Amortized TI: How Much Is the Landlord Really Charging Me?

What "amortized TI" actually is, versus a real allowance

Tenant-improvement money arrives in two very different shapes, and landlords rarely draw the line for you. A base allowance is the landlord's own contribution to win your lease — you spend it on the buildout and you never repay it. It is genuinely free capital, quoted as a lump sum or as dollars per square foot. Amortized TI — sometimes labeled "additional TI," "over-allowance," or "landlord's contribution to be repaid as additional rent" — is the opposite. It is money the landlord *lends* you for construction and recovers through a monthly rent increase, with interest, spread across the lease term.

The reason the distinction matters so much is that amortized TI is debt dressed up as rent. When a landlord says "we can do another $100,000 of TI, it just adds about $2,076 a month to your rent," what they have actually done is originate a five-year loan at roughly 9% interest and hand you the payment coupon without naming the rate. Nothing on the term sheet says "loan." Nothing says "9%." You see a rent number that sounds manageable, and the financing cost hides inside it. Treat every dollar of amortized TI as borrowed money, because that is exactly what it is — and the interest rate is almost always higher than what a bank would charge you for the same construction.

The practical takeaway: before you get anywhere near a signature, force the deal into two clean buckets. How many dollars are free base allowance you never repay, and how many dollars are amortized TI you are borrowing? Those are different economics, and negotiating them as one blended "TI package" is how tenants quietly overpay for years.

The real cost — run the numbers before you initial the page

Amortized TI only looks cheap because you never see the total. Run the amortization yourself and the true cost appears immediately. Assume $100,000 of additional TI and hold the principal constant while you vary the rate and term:

• 5-year (60-month) term at 8%: about $2,028/month, roughly $21,650 in total interest — you repay about $121,650 for $100,000.
• 5-year term at 9%: about $2,076/month, roughly $24,500 in total interest — repaying about $124,500.
• 5-year term at 10%: about $2,125/month, roughly $27,500 in total interest.
• 5-year term at 12%: monthly climbs further, total interest near $33,500 — roughly $12,000 more than the same buildout at 8%.

Now watch what a longer amortization does. Stretch the same $100,000 at 9% over 10 years and the monthly payment drops to about $1,267 — which *feels* like a better deal — but total interest balloons to roughly $52,000 because you are paying for twice as long. This is the single most important pattern to internalize: a lower monthly payment from a longer term is more expensive overall. Landlords know a smaller monthly number closes deals, so they will happily stretch the amortization; your job is to look past the payment and at the total repayment.

Every percentage point is real cash. On a $100,000 five-year loan, each point of rate is worth roughly $2,500–$3,000 in lifetime interest. So the difference between accepting the landlord's opening 10% and negotiating down to 7% is not rounding error — it is thousands of dollars pulled out of your operating account and moved into theirs. The discipline is simple: get the principal, get the rate, get the term, and compute the total repayment before you agree to anything. If the landlord won't give you the rate, you cannot run this math — which is precisely why they don't volunteer it.

The tricks hidden inside the rent add-on

Amortized TI is a fine-print game, and most of the money is lost in clauses tenants never read closely. Watch for each of these:

The unnamed rate. By far the most common maneuver — a monthly rent bump with no interest rate stated anywhere. Always back into the effective rate from the quoted monthly payment and the principal, then insist that the rate appears in the executed work-letter. No stated rate, no signature.

Amortization longer than your lease term. If the TI amortizes over 10 years but your initial term is only 7, the unpaid balance doesn't vanish — it becomes a balloon you owe at expiration or if you leave early. You borrowed over a schedule longer than your commitment, so you never actually finish paying inside the term you signed for.

Repayment that survives early termination. Many leases accelerate the *unamortized* TI balance the moment you break the lease — the clause usually reads "in the event of early termination, the unamortized balance shall be immediately due." Exit in year two of a five-year deal and you owe the entire remaining buildout cost in one lump, stacked on top of any separate termination penalty. Read the termination and default sections specifically for this language.

Interest charged on the free allowance. Confirm the interest rate applies only to the additional TI you are actually borrowing — not to the base allowance the landlord is supposed to be contributing for free. Sloppy or aggressive drafting sometimes amortizes the whole package, quietly turning free money into financed money.

Compounding, fees, and layered charges. Make sure the amortization is simple, with no origination fee, no administrative markup, and no compounding trick sitting on top of the headline rate. A "9%" that compounds or carries a fee is not really 9%.

The defense against all of this is the same: ask the landlord to break out, in writing, three numbers — the principal (actual TI dollars spent on your behalf), the rate, and the total repayment across the term. If they resist itemizing, that resistance tells you who the structure favors.

How to spot amortized TI buried in the lease language

Landlords rarely stamp "loan" on this. The amortized portion either folds invisibly into your base rent or surfaces as a separate "additional rent" line, and the drafting is deliberately dry. Learn to recognize the tells in the work-letter and rent schedule.

Look for "amortized over the initial term at [X]% per annum." That percentage *is* your interest rate — and if it reads 10% or 12%, you are paying a near-credit-card rate for drywall, HVAC, and paint. Look for "landlord's contribution to be repaid as additional rent," which is simply a loan wearing a rent costume. And hunt specifically for the acceleration clause — "upon early termination the unamortized balance shall become immediately due" — because that one line can turn a routine year-three exit into a six-figure surprise bill.

The cleanest way to expose the real cost is a side-by-side: ask for the base rent with zero TI financing versus the base rent with the amortized package. The monthly gap between those two numbers, annualized, is your true cost of the money — no interpretation required. If the landlord will quote you the second number but suddenly can't produce the first, you have learned something important about how transparent this deal really is. A tenant-rep broker or real estate attorney earns their fee fast here; they read these clauses for a living and know which phrases hide the acceleration and balloon risk.

Negotiating the rate — and the term — down

The interest rate on amortized TI is not a law of physics. It is the landlord's opening number, and like every other line in a lease it moves under pressure. Several levers actually work:

Anchor to their cost of capital, not yours. Landlords borrow against the building at commercial mortgage rates. Point out plainly that they are re-lending you money at a markup over what they themselves pay, and ask them to amortize at their own cost of funds plus a thin spread rather than a retail 8%–10%. Framing the rate as *their margin* rather than *your privilege* reframes the whole conversation.

Trade term for rate. The entire reason landlords amortize TI is to lock in tenancy — the financing is a retention tool. If you are willing to sign a longer initial term or add option years, you hold real leverage to push the rate down a point or two, because the longer commitment is the thing they actually want in exchange.

Cap the early-exit exposure. Even when you can't kill the acceleration clause outright, negotiate it into a declining balance or a fixed buyout schedule so an early departure doesn't detonate the full unpaid principal in one payment. Converting "entire remaining balance immediately due" into "the then-unamortized balance on a stated schedule" dramatically shrinks your downside.

Split the difference on principal. Offer to fund part of the buildout in cash in exchange for a lower amortization rate on the remainder. Cash you bring up front isn't financed at 9% at all, and it shrinks the principal the interest accrues on — a double savings. Maximize the *free base allowance* first for the same reason: every non-amortized dollar is a dollar you never repay with interest.

Every quarter-point you shave off a $100,000 buildout, over a multi-year term, is real money that stays in your operating account instead of the landlord's.

When amortized TI is actually the right call

It isn't always a trap. The structure exists because it genuinely solves a cash-flow problem, and there are real situations where taking the landlord's money is the smart move even at a premium rate.

You're capital-constrained at signing. If paying for the buildout yourself would drain the cash you need for inventory, payroll, and the first lean months of operating, financing it through rent — even at 9% — can beat the alternative of not opening at all. Preserving working capital has value that a spreadsheet interest comparison alone doesn't capture.

You can't qualify for outside financing yet. A brand-new entity with no operating history often can't land an SBA 7(a) or an equipment loan on day one. The landlord, who already controls the asset and has recourse to your lease, may extend credit a bank simply won't. In that case the amortized rate isn't being compared against 6% — it's being compared against *no loan available*.

The improvements are landlord-specific. When most of the buildout is base-building work that stays with the space — structural, HVAC, electrical, plumbing — there's a fair argument the landlord should carry some of it, because it raises the property's long-term value whether or not you renew. Financing that portion through the lease at least aligns the debt with the asset it improves.

You have strong term certainty. If you're confident you'll ride out the full term and won't trigger the early-exit clause, the balloon and acceleration risks that make amortized TI dangerous are largely off the table for you specifically.

The honest rule: amortized TI is a financing tool, and like any loan it's fine when the rate is fair and the terms are clean. The danger is treating "free" landlord money as free when it's actually one of the more expensive loans you'll ever sign. The deciding question is always the same — the rate versus your real alternatives, plus the early-exit language — so run the total-repayment number before you initial the page.

A quick decision framework

Boil the whole negotiation down to five moves you can run in order. First, separate the base allowance from the amortized TI — one is free, one is a loan with interest, and blending them hides the cost. Second, demand the interest rate in writing and amortize it yourself before signing so you know the total repayment, not just the monthly. Third, compare that rate to real financing at 6%–9% (SBA 7(a), SBA 504, an equipment loan, or a line of credit) and borrow elsewhere if the landlord wants 10%+. Fourth, match the amortization to the lease term — never longer — to eliminate balloon and acceleration exposure. Fifth, negotiate the biggest free allowance first, because that is the money you never repay with interest at all. Follow those five steps and you'll never sign a 12% buildout loan by accident.

FAQ

What does it mean when a landlord amortizes tenant improvements? It means the landlord fronts the cost of your buildout and adds it back into your rent over the lease term, plus interest. You're effectively borrowing the construction money from your landlord and repaying it through higher monthly rent. The essential point is that this is a loan, not free money — treat the rent bump as a loan payment.

What interest rate do landlords typically charge on amortized TI? Landlords commonly amortize TI somewhere in the 8%–10% range, and sometimes 12% or higher, which is usually above what you'd pay a bank for comparable financing. The exact rate depends on the landlord, the market, and your leverage. Always insist the rate is stated explicitly in the lease rather than buried inside the rent number.

Is amortized TI always a bad deal? No. If you lack upfront capital and can't get cheaper financing elsewhere, it can be a reasonable way to fund a buildout. The problem arises when the rate is undisclosed or far above market borrowing costs. The deal is only as bad as the interest rate and terms you accept, so negotiate both before agreeing.

How can I tell how much of my rent is really TI repayment? Ask the landlord to break out the base rent and the amortized TI portion separately, along with the principal and stated rate. If they won't itemize it, that resistance signals the markup may favor them. Knowing the split lets you back into the implied interest rate and compare it against other financing options.

Can I negotiate the terms of amortized TI? Yes — the interest rate, the amortization period, the total allowance, and the early-exit clause are all negotiable. You can trade a longer initial term for a lower rate, fund part of the buildout in cash to shrink the principal, or push for more free allowance instead of financing. Your leverage depends on market conditions and how much the landlord wants you.

Does the interest apply to my free base allowance too? It shouldn't. Interest should apply only to the additional TI you're actually borrowing, never to the base allowance the landlord contributes for free. Confirm this in the work-letter, because loose drafting sometimes amortizes the entire package — quietly turning free money into financed money at the same rate as your loan.

What happens to amortized TI if I break the lease early? It depends entirely on your lease language. Many leases accelerate the unamortized balance on early termination, making the full remaining buildout cost immediately due on top of any termination penalty. Read the default and termination clauses before signing, and negotiate a declining-balance or buyout schedule to cap the exposure.

Is amortized TI cheaper than an SBA or equipment loan? Usually not. SBA 7(a), SBA 504, and equipment loans commonly land in the 6%–9% range, below a typical 8%–12% landlord rate. If you can qualify and can absorb the paperwork, outside financing is often cheaper and keeps construction debt off your lease and off the landlord's leverage over you.
