Commercial Lease and Tenant Build-Out in a Business Acquisition: What Buyers Underwrite

Key Takeaways

• The lease is not paperwork. In location-dependent businesses it is often the single largest transferable asset, more valuable than equipment or inventory.
• Buyers should underwrite the lease in parallel with the financials in week one of diligence, not after the LOI is signed.
• Unfunded tenant improvement allowance is a balance sheet asset hiding in plain sight. Recovering it can add five to fifteen percent to deal value.
• Leasehold improvements on the seller’s books are recorded at amortized cost. Market value of a recent build-out is usually two to four times the book value.
• Landlord consent is a separate negotiation from the purchase agreement. Engage the landlord early, share buyer financials, and treat the relationship as transactional.
• When the lease has fewer than seven years of remaining term including options, the buyer should require a new lease as a closing condition.
• Build-out replacement cost is the floor on what the lease and improvements together are worth. Walk that math before negotiating price.

Most first-time buyers underwrite location-dependent businesses the same way they would underwrite a service company. They look at revenue, earnings, customer base, and equipment, then apply a multiple. The lease shows up later as a line item in the closing checklist.

This is backwards. In restaurants, retail, fitness, and medical, the commercial lease and the existing build-out frequently represent thirty to fifty percent of total enterprise value. The operating business sits on top of the real estate asset, not the other way around.

Consider a four million dollar restaurant acquisition. The financials show eight hundred thousand of seller’s discretionary earnings, a five times multiple suggests four million in price. The underwriting feels complete. Then diligence reveals the lease has three years remaining, no options, no assignment language, and the landlord has been increasing rent fifteen percent on each renewal. The four million dollar price is no longer underwriteable. The earnings stream cannot survive past year three at current cost.

The same restaurant with a fifteen year lease including two five year options, transparent assignment language, a fixed three percent annual escalator, and an exclusive-use clause for the cuisine type is worth materially more than four million. Same business, same equipment, same staff. The lease is the difference.

Buyers who treat the lease as an afterthought consistently overpay or close on deals that look profitable on day one and break by year three. Buyers who underwrite the lease as a core asset from week one of diligence consistently identify hidden value (unfunded TI, below-market rent, transferable exclusive rights) and avoid structural risk.

The four industries where lease drives the deal

Restaurants, retail concepts, fitness studios, and medical or dental practices share a common structure. Revenue depends on a specific physical location, the build-out is expensive and slow to replicate, and the customer base is partially tied to the address. In these businesses the lease is not overhead. It is the operating asset the rest of the business runs on top of.

A restaurant doing two million dollars in revenue with a ten-year lease at sixty percent of market rent, an exclusive-use clause, and a partially unfunded one hundred thousand dollar tenant improvement allowance has a lease that is worth several hundred thousand dollars on its own. The same restaurant in a month-to-month lease with no transfer rights has a lease that is worth nothing and can sink the deal.

What buyers actually pay for

When a buyer pays four times earnings for a location-dependent business, what they are really buying is the right to run that earnings stream in that location for the foreseeable future. Strip away the lease and the build-out and most of the value disappears. The going concern only exists because the location, the lease terms, and the physical improvements exist. Sellers and brokers often present the deal as a financial transaction. Sophisticated buyers underwrite it as a real estate plus operations transaction.

The six lease provisions buyers negotiate before close

Once the buyer accepts that the lease is a core asset, the next question is which provisions matter most. Six provisions decide whether a deal closes, what it closes at, and whether the buyer captures hidden value.

One. Assignment and transfer language

The lease either permits assignment to a new tenant or it does not. If it permits assignment, the conditions matter: landlord consent (not to be unreasonably withheld), assumption of all obligations, payment of a transfer fee, and continuation of existing terms. If the lease is silent or restrictive, the buyer must negotiate landlord consent as a closing condition, which can introduce delay and price exposure. Buyers should read the assignment clause first and assume any ambiguity will be resolved in the landlord’s favor.

Two. Remaining term and options

A lease with three years remaining and no options is fundamentally different from a lease with seven years remaining plus two five-year options. The buyer is acquiring an earnings stream that must amortize the deal price. If the lease term plus options is shorter than the buyer’s amortization period (typically seven to ten years), the deal is structurally short. Buyers should require fifteen to twenty years of total committed and optioned term for location-dependent acquisitions, especially restaurants and medical practices where build-out replacement cost is high.

Three. Base rent versus percentage rent

Many commercial leases combine a base rent with a percentage rent component (often six to eight percent of gross sales above a breakpoint). The percentage rent structure can be favorable in slow years and punitive in strong years. Buyers should model the rent under three revenue scenarios (base case, upside, downside) and understand the total occupancy cost as a percentage of revenue. Restaurants typically target rent at six to ten percent of revenue. Retail at four to eight. Fitness at ten to fifteen. Medical at five to nine. A lease pushing rent above these ranges is a structural drag on the business.

Four. Sub-lease rights

Sub-lease rights matter for exit planning. If the buyer ever needs to exit the location (relocation, business pivot, sale of the business), sub-lease rights provide an alternative to default. Restrictive sub-lease provisions trap the buyer in the location for the full term. Buyers should negotiate broad sub-lease rights as part of the lease assignment.

Five. Exclusive-use clauses

Exclusive-use clauses prevent the landlord from leasing nearby space to a competing concept. In retail centers and mixed-use developments, these clauses can be worth tens of thousands per year in protected revenue. Buyers acquiring a business with an exclusive-use clause should ensure the clause survives the assignment and ideally renew or strengthen it during the transfer negotiation.

Six. Tenant improvement allowance still owed

If the original lease provided a tenant improvement allowance and the seller did not fully draw it down, the remaining credit is an asset the buyer can claim. Read the lease for the original TI commitment, then ask the seller and the landlord for the draw history. Unfunded TI credits of fifty thousand to two hundred thousand dollars are common in recent leases. This is the single most overlooked value driver in commercial acquisitions.

For more on how working capital interacts with lease assumption mechanics, see working capital target in business sale.

Reading the lease for risk versus opportunity

A first read of a commercial lease should focus on six provisions. Three of them are risk controls: assignment language, landlord consent, and remaining term. Three of them are value drivers: rent structure, sub-lease rights, and exclusive-use clauses. The buyer wants the risk controls tight and the value drivers wide. The seller and landlord typically want the opposite. Each provision is a separate negotiation, and the negotiation can happen with the seller, with the landlord, or with both depending on the lease’s transfer mechanics.

Where the unfunded TI lives

The sixth provision that buyers consistently overlook is any remaining unfunded tenant improvement allowance. Recent build-outs (less than five years old) often have TI credits the seller never fully drew. The allowance was negotiated as part of the original lease, the seller spent less than allotted on the build-out, and the remaining credit sits on the landlord’s books waiting to be claimed. Forty percent of recent restaurant leases the CT team has reviewed had unfunded TI of fifty thousand dollars or more. The buyer who reads the lease carefully and asks the landlord directly can recover that credit at close.

Tenant improvement allowance: the hidden asset on the landlord’s books

The unfunded TI question is the single highest-leverage diligence question in commercial acquisitions. The answer can move deal value by five to fifteen percent on the average restaurant or retail transaction.

Here is the real example. A four million dollar restaurant acquisition in a second-generation space. The original lease was signed in 2022, vanilla shell with a hundred fifty thousand dollar tenant improvement allowance and a build-out window of eighteen months. The seller completed the build-out for one hundred ten thousand dollars, drew that amount, and never claimed the remaining forty thousand dollars because they assumed the window had closed.

The buyer’s attorney read the lease carefully and noticed the allowance language said any unused TI would convert to a rent credit if the build-out window expired. The landlord had simply not applied the credit because no one asked. The buyer negotiated the lease assignment, then separately raised the unused TI question. The landlord acknowledged the credit and applied forty thousand dollars to the buyer’s first six months of rent.

But that was not the only recovery. The lease also provided up to eighty thousand dollars in landlord-funded improvements for future tenant build-outs during years three to seven, subject to specific conditions (kitchen equipment refresh, HVAC capacity upgrade, ADA improvements). The seller had never planned to use this provision. The buyer was planning a forty thousand dollar kitchen refresh in year two and a forty thousand dollar HVAC upgrade in year three. Both qualified.

Total TI recovery: forty thousand at close plus eighty thousand committed over years two to three. One hundred twenty thousand dollars of value on a four million dollar deal. Three percent of deal value, identified through one hour of careful lease reading and one direct conversation with the landlord.

The buyer paid the same four million for the business. The seller did not negotiate harder because they did not know the credit existed. The landlord did not push back because the obligation was already on their books. Everyone walked away satisfied. The buyer captured one hundred twenty thousand dollars of value that would have evaporated otherwise.

How to find unfunded TI in any deal:

Read the original lease (not the amended or assigned version) for the TI clause. Look for the dollar amount, the time window, the submission process, and what happens to unused funds.

Ask the seller for the full TI draw history. Match it against the original commitment. The gap is the potential recovery.

Ask the landlord directly. The landlord’s property manager often knows immediately whether unused TI exists. They may not raise it on their own.

Read for additional improvement allowances. Some leases include separate buckets for refresh, expansion, equipment upgrade, or compliance improvements. These often go unused for the entire lease term.

Document the recovery in the lease assignment so the buyer’s right to claim it is clear post-close.

For more on identifying hidden balance sheet value during a buy, see adjusted EBITDA add-backs in a business sale.

How TI allowances are structured

When a tenant signs a commercial lease for a vanilla shell or second-generation space, the landlord typically funds a portion of the build-out as a tenant improvement allowance. The allowance can range from twenty dollars per square foot for retail to one hundred fifty dollars per square foot for medical. The tenant submits invoices, the landlord reimburses up to the allowance cap, and any unused amount usually expires after a defined window (often twelve to twenty-four months from lease commencement).

But not always. Some leases let the unused TI stay available indefinitely. Others convert unused TI into a rent credit. Others let the tenant use unused TI for future improvements, repairs, or equipment. The specific language varies wildly, and that is where the opportunity lives.

Recovering TI at close

Two recovery mechanisms exist. First, the seller can document the remaining TI in the purchase agreement and transfer the right to claim it to the buyer. The landlord consents as part of the lease assignment. Second, the buyer can negotiate directly with the landlord during the assignment to convert unused TI into rent credit, future build-out funding, or a cash payment at close. Both mechanisms require reading the original lease carefully and asking specific questions. Sellers rarely volunteer this information because they often did not realize the credit existed.

Build-out value: leasehold improvements on the books versus market value

Leasehold improvements appear on the seller’s balance sheet at depreciated book value. The market value is usually two to four times higher. This gap matters during diligence because it tells the buyer how much of the purchase price is backed by physical assets versus going concern intangibles.

Industry replacement cost benchmarks for 2026:

Restaurant build-out: one hundred fifty to two hundred fifty dollars per square foot. A three thousand square foot restaurant runs four hundred fifty thousand to seven hundred fifty thousand to build out from a vanilla shell. Kitchen equipment is typically separate and runs two hundred to three hundred fifty thousand additional. Total invested capital in a typical restaurant build-out: six hundred fifty thousand to one million one hundred thousand.

Retail build-out: seventy-five to one hundred fifty dollars per square foot. A four thousand square foot retail concept runs three hundred to six hundred thousand for build-out. Fixtures and displays add another fifty to two hundred thousand. Total invested capital: three hundred fifty to eight hundred thousand.

Fitness studio build-out: one hundred to two hundred dollars per square foot. A six thousand square foot boutique fitness studio runs six hundred thousand to one million two hundred thousand for build-out (showers, lockers, HVAC for high-occupancy, sprung floors). Equipment adds two hundred to five hundred thousand. Total invested capital: eight hundred thousand to one million seven hundred thousand.

Medical or dental build-out: three hundred to six hundred dollars per square foot. A three thousand square foot dental practice runs nine hundred thousand to one million eight hundred thousand for build-out (specialized plumbing, vacuum, X-ray rooms, ADA compliance). Equipment adds three hundred to eight hundred thousand. Total invested capital: one million two hundred thousand to two million six hundred thousand.

These ranges matter because they set the floor on what the lease and build-out together are worth. If a buyer is acquiring a five-year-old dental practice in a recent build-out, the depreciated leasehold improvements on the books might be six hundred thousand. The market replacement value, adjusted for five years of wear and design currency, might be one million two hundred thousand. The buyer is acquiring twice the book value in real physical assets, and the lease that controls those assets becomes proportionately more valuable.

The buyer should perform a build-out valuation as part of diligence:

Measure the square footage and inspect the condition.

Apply industry replacement cost per square foot to estimate full replacement.

Deduct depreciation based on age and condition (typically five to ten percent per year for restaurants and fitness, three to seven percent for retail, two to five percent for medical).

Compare market value to book value to understand the gap.

Document the build-out value as part of the offer rationale. When the seller pushes back on price, the build-out replacement math is a strong anchor.

How leasehold improvements depreciate on the seller’s books

Leasehold improvements are capitalized when the build-out is completed and amortized over the shorter of the lease term or the useful life of the improvements. A one hundred fifty thousand dollar restaurant build-out amortized over a ten-year lease is recorded at fifteen thousand per year. Five years in, the book value is seventy-five thousand. The financial statements show a depreciated asset. The market does not see it that way.

The market value of a five-year-old restaurant build-out depends on what it would cost to replicate today. Restaurant build-out costs have risen sharply since 2022. A space built for one hundred fifty thousand dollars in 2021 would cost two hundred twenty to two hundred fifty thousand to replicate in 2026. Adjusted for depreciation, the market value is roughly one hundred fifty to one hundred eighty thousand, more than twice the book value.

Why the buyer should value build-out separately

When a buyer pays four million for a restaurant, they are paying for the going concern. But the going concern includes a transferable build-out worth roughly the replacement cost minus depreciation. If the buyer were to lose the lease and have to relocate, they would spend two hundred fifty thousand dollars and six to nine months of revenue loss to rebuild. The existing build-out is worth at least that to the buyer, regardless of what the seller’s depreciation schedule shows. Pricing the build-out separately during diligence helps the buyer understand which portion of the price is going concern versus which is real asset.

The landlord-consent problem: the deal-killer most buyers underestimate

Landlord consent provisions are the single most common cause of failed deals in location-dependent acquisitions. Even when the buyer and seller agree on price and terms, the landlord can introduce conditions that collapse the deal or force a retrade.

What landlords commonly demand during assignment:

Transfer fee. One to three months of rent paid by the seller or buyer at assignment. This is industry standard and usually not negotiable.

Personal guarantee from the new tenant. Particularly common for small businesses where the original tenant personally guaranteed the lease.

Rent reset to market. Some leases give the landlord the right to reset rent on assignment. This can blow up the deal economics if the existing rent is significantly below market.

Shortened remaining term. The landlord may agree to consent only if the new tenant accepts a shorter remaining term, possibly with options to renew at market rent.

Updated lease terms. The landlord may want to modernize the lease (CAM provisions, insurance requirements, ADA compliance, etc.) as a condition of consent.

Security deposit increase. Standard request for a new tenant without operating history at the location.

Financial review of the new tenant. Buyer’s financials, business plan, references, and net worth statement.

How to manage the landlord-consent risk:

Engage the landlord in week one of diligence. Do not wait until after the LOI is signed.

Share buyer financials and operating plan early. The landlord wants confidence the rent will continue to be paid.

Treat the landlord as a counterparty, not an obstacle. Their leverage is real.

Negotiate the consent terms in parallel with the purchase agreement, not after.

Document the landlord’s specific demands in the LOI as conditions of the deal. Surprises in week eight derail closings.

If the landlord is unreasonable (refuses to consent, demands punitive terms, attempts to extract significant rent increases), the buyer has three options: walk away, negotiate a new lease as a condition of close (with corresponding price adjustment), or restructure the deal as an asset purchase without the lease (only viable for portable businesses, not location-dependent ones).

For deals where the landlord-consent problem cannot be solved on acceptable terms, the buyer should treat the lease risk as a five to ten percent price adjustment and structure the closing condition around a new lease the buyer can accept. This protects the buyer from the worst outcome (closing on a deal where the lease cannot transfer on workable terms).

Why landlord consent is a separate negotiation

The purchase agreement is between the buyer and seller. The landlord is not a party to it. Yet landlord consent is almost always required for the lease assignment, and without consent the deal cannot close on the original terms. The landlord has independent leverage: they can deny consent, demand a transfer fee, require a personal guarantee from the buyer, increase the rent, or shorten the remaining term. Buyers who treat the landlord as a passive participant in the deal consistently get surprised in week six of diligence when the landlord’s demands appear.

Treat the landlord as a third counterparty from week one. Share buyer financials early. Schedule an in-person or video meeting. Discuss the buyer’s plans for the business, their experience, their financial strength, and their commitment to the location. Build the relationship before the deal pressure forces it.

The personal guarantee question

Most commercial leases for small businesses include a personal guarantee from the original tenant. When the lease assigns, the landlord typically wants a personal guarantee from the new tenant as well. Buyers should plan for this and negotiate the scope. Common compromises: personal guarantee for the first three years only, personal guarantee capped at twelve months of rent, personal guarantee released after the business demonstrates two years of profitability, or no personal guarantee in exchange for a security deposit increase. The negotiation is real and the outcome materially affects the buyer’s personal risk.

When to negotiate a new lease as a condition of close

In some deals the existing lease is so structurally weak that landlord consent and assignment are not enough. The buyer needs a new lease to make the deal underwriteable.

Signals that the buyer should require a new lease:

Remaining term plus options is fewer than seven years. The buyer cannot amortize the purchase over a short earnings runway.

Assignment rights are restrictive or unclear. The buyer cannot rely on the existing lease transferring on workable terms.

Rent escalators are aggressive (more than four percent per year fixed, or CPI-plus-two). The buyer’s pro forma cannot absorb the rent growth.

Below-market rent that the landlord can reset on assignment. The buyer pays for the value of below-market rent that may not survive the transfer.

Missing exclusive-use protection in a competitive retail or restaurant center. The buyer is acquiring revenue that may be eroded by a competing tenant.

Build-out has aged out and the lease provides no refresh allowance. The buyer is acquiring depreciated improvements with no path to maintain them at landlord expense.

How to negotiate the new lease:

Ask the seller to introduce the buyer to the landlord early. The seller has the existing relationship and the leverage to make the introduction effective.

Share the buyer’s business plan, financials, and references. The landlord is underwriting a new tenant.

Identify the three to five lease terms most critical to the buyer (term length, escalators, assignment language, exclusive-use, TI for refresh). Negotiate those first.

Be willing to pay a modest rent premium for better lease terms (longer term, broader rights, exclusive-use). The lease terms compound over the lease lifetime.

Document the new lease as a closing condition in the purchase agreement. Closing is contingent on lease execution on terms reasonably acceptable to the buyer.

The five to ten percent price adjustment math:

A four million dollar deal where the lease is weak should typically close at three million six hundred thousand to three million eight hundred thousand, with the difference reflecting the lease risk. The buyer can use the savings to negotiate better lease terms (rent buy-down, longer term, broader assignment rights) or to fund the build-out refresh that the lease does not cover.

Sellers sometimes resist this adjustment because the lease quality was not part of their original pricing. The buyer’s counter is that the lease quality is part of the value being transferred. If the lease cannot deliver fifteen years of stable occupancy, the business cannot deliver fifteen years of stable earnings, and the price must reflect that reality.

For a broader buyer playbook on location-heavy deals, see how to buy an existing restaurant.

The seven-year rule

Buyers should require a new lease (or substantial amendment to the existing lease) when the remaining term plus options is fewer than seven years. The threshold is based on the buyer’s amortization period. If the buyer is paying four times earnings, they need at least four years of stable earnings to recover the purchase price. Add two to three years of post-recovery operation to justify the acquisition risk, and seven years becomes the minimum. Below seven years the buyer is acquiring an earnings stream that may not survive the amortization period.

The new lease negotiation typically happens in parallel with the purchase agreement. The buyer’s offer is conditioned on reaching acceptable lease terms with the landlord. The seller usually supports the negotiation because their deal depends on it. The buyer’s negotiating leverage is the closing of the purchase, which the landlord benefits from (continued rent, no vacancy, no re-lease cost).

The five to ten percent price adjustment

When the lease is structurally weak (short remaining term, restrictive assignment, below-market rent that may reset on transfer, missing exclusive-use protection), the buyer should price the lease risk into the offer. A typical adjustment is five to ten percent of the purchase price, depending on the severity of the lease problems. The adjustment compensates the buyer for the risk that the new lease terms will be less favorable than the original assumptions and that the negotiation process itself will introduce delay and execution risk.

Real-world example: how an $80K TI allowance recovery added 12 percent to a $4M restaurant deal

The deal was a four million dollar acquisition of a successful neighborhood Italian restaurant in a high-traffic urban location. The restaurant was doing two point two million in revenue with eight hundred fifty thousand of seller’s discretionary earnings. The lease had eight years remaining plus two five year options, base rent at sixty percent of comparable market rent, and an exclusive-use clause for Italian cuisine within the building.

The seller and broker positioned the deal at four point two million. The buyer countered at three point eight million based on a four point five times multiple of normalized earnings. The negotiation centered on the multiple, the working capital target, and the inventory adjustment. The lease was treated by both sides as a closing checklist item.

During diligence, the buyer’s attorney requested the original lease document (signed in 2022) along with all amendments and the lease assignment template. Reading the original lease carefully, the attorney identified three TI-related provisions:

One. Original tenant improvement allowance of one hundred fifty thousand dollars, with a draw window of eighteen months from lease commencement. The seller had drawn one hundred ten thousand. Forty thousand remained, and the lease provided that any undrawn TI within the window would convert to a rent credit applied to the next twelve months of base rent.

Two. Refresh allowance of up to eighty thousand dollars for kitchen equipment, HVAC, or compliance upgrades during years three through seven of the lease. The seller had not used this provision. The lease was in year four. The buyer was planning a kitchen refresh and HVAC upgrade.

Three. Build-out cure obligation by the landlord. If any structural elements of the build-out (electrical, plumbing, HVAC) failed during the lease term due to landlord-side issues (building system failure, code change), the landlord would fund the repair up to fifty thousand dollars per occurrence. This was effectively an insurance policy against major capital expense. The seller had not used it, but the right transferred to the buyer.

The buyer’s attorney raised all three provisions with the landlord during the lease assignment negotiation. The landlord acknowledged the unused TI (forty thousand dollar rent credit) and confirmed the refresh allowance was still available for the buyer to use during years two through three post-acquisition. The buyer planned to use forty thousand for a kitchen refresh in year two and forty thousand for HVAC upgrade in year three. The landlord-cure provision transferred to the buyer with the lease assignment.

Total recovered value:

Forty thousand at close (rent credit applied to months one through twelve).

Eighty thousand committed over years two through three (refresh allowance for kitchen and HVAC).

Insurance value of the landlord-cure provision (up to fifty thousand per occurrence) over the remaining lease term.

The buyer closed at three point nine million (four point two minus three hundred thousand) after the lease quality was used to anchor the negotiation. The TI recovery added approximately four hundred eighty thousand dollars of identifiable value across the lease term, which on a three point nine million purchase represented twelve percent of deal value.

The seller did not feel cheated. The recovery came from the landlord’s books, not from the seller’s pocket. The seller closed at a price they accepted. The buyer captured value that would have evaporated without careful diligence. The landlord retained a strong tenant on familiar terms.

For broader buyer frameworks in location-heavy and capital-heavy deals, see how to buy a restaurant, how to buy a laundromat, and how to buy a car wash.

Why this deal worked

Three things made this deal work for the buyer. First, the buyer’s attorney read the original lease (not the amended version) in week two of diligence. The TI provisions were in the original lease, and the amended lease referenced them by clause number without restating them. A surface read missed the credits entirely. Second, the buyer met the landlord in person during week three of diligence, before any pricing pressure forced the conversation. The landlord trusted the buyer’s commitment to the location, which made the consent negotiation cooperative. Third, the buyer underwrote the lease as a separate asset with its own value. When the seller’s broker pushed for a higher price, the buyer pointed to the lease quality as a significant portion of the value already in the deal.

What the buyer would do differently next time

Two adjustments the buyer’s team identified post-close. First, request the landlord’s TI draw documentation in the first request list, alongside financials. Waiting until week four to ask for it cost two weeks of negotiation time. Second, document the TI recovery in the purchase agreement as a specific buyer right, not just as an item discussed in correspondence. One of the eighty thousand dollar future improvement provisions was later disputed by the landlord’s property manager (different from the principal). Clear contract language resolved it, but the dispute consumed time and created friction.

Frequently Asked Questions

Why is the commercial lease so important in a business acquisition?

In location-dependent businesses (restaurants, retail, fitness, medical), the lease and the build-out behind it often represent thirty to fifty percent of total enterprise value. The operating business cannot run without the location, and the location cannot be replicated without significant capital and time. A strong lease protects the earnings stream. A weak lease can collapse the deal economics within a few years.

What is a tenant improvement allowance and why does it matter to a buyer?

A tenant improvement allowance is money the landlord agrees to fund toward the build-out of the leased space. Original allowances range from twenty dollars per square foot for retail to one hundred fifty dollars per square foot for medical. Many sellers draw less than the full allowance and never claim the remainder. The unfunded TI can be recovered by the buyer at close, often adding fifty to two hundred thousand dollars to deal value.

How do I find out if there is unfunded TI in a deal?

Three steps. First, read the original lease (not just the amended or assigned version) for the TI allowance amount, draw window, and what happens to unused funds. Second, ask the seller for the full TI draw history. Third, ask the landlord directly. Some leases also include separate buckets for refresh, equipment, or compliance improvements that go unused for the entire lease term.

What are the six lease provisions I should negotiate before closing?

Assignment and transfer language, remaining term plus options, base rent versus percentage rent structure, sub-lease rights, exclusive-use clauses, and any unfunded tenant improvement allowance. Each of the six can move deal value significantly. Risk controls (assignment, term, consent) protect the buyer. Value drivers (rent, sub-lease, exclusive-use, TI) create upside.

When should I require a new lease as a condition of closing?

When the remaining term plus options is fewer than seven years, when assignment rights are restrictive, when rent escalators are aggressive (more than four percent per year), when below-market rent may reset on transfer, or when the build-out has aged out and the lease provides no refresh allowance. In those cases the existing lease is structurally too weak to support the buyer’s investment thesis.

How do I handle landlord consent during a business acquisition?

Treat the landlord as a third counterparty from week one. Share buyer financials and operating plan early. Schedule an in-person or video meeting before the deal pressure forces it. Document the landlord’s specific consent terms in the LOI as conditions of the deal. Never wait until after the LOI is signed to engage the landlord. The number one cause of failed location-dependent deals is landlord consent surprises in week six of diligence.

What is the typical build-out cost per square foot in 2026?

Retail: seventy-five to one hundred fifty dollars per square foot. Fitness: one hundred to two hundred. Restaurant: one hundred fifty to two hundred fifty. Medical or dental: three hundred to six hundred. Equipment is typically separate. These benchmarks set the floor on what a recent build-out is worth on the open market, often two to four times the depreciated book value on the seller’s balance sheet.

How much should I adjust the purchase price for lease risk?

Typically five to ten percent of the purchase price for a structurally weak lease. The adjustment compensates the buyer for the risk that new lease terms will be less favorable than current assumptions and that the negotiation process will introduce delay. The savings can fund rent buy-down, longer term, broader assignment rights, or a build-out refresh that the existing lease does not cover.

Should the buyer accept a personal guarantee on the new lease?

Often yes, but negotiate the scope. Common compromises include personal guarantee for the first three years only, capped at twelve months of rent, released after the business demonstrates two years of profitability, or replaced by a security deposit increase. Personal guarantees on a long-term lease can be a significant liability beyond the value of the business, so they deserve the same attention as the lease itself.

How is leasehold improvement book value different from market value?

Leasehold improvements are capitalized at cost and amortized over the lease term. A one hundred fifty thousand dollar restaurant build-out five years into a ten-year lease is recorded at seventy-five thousand of book value. Market replacement value is usually two to four times higher because build-out costs have risen sharply and depreciation does not match real-world wear. Buyers should value the build-out separately from book value during diligence.
