The Promise vs. the Bank

What Every Business Owner Should Know Before Signing a Commercial Lease

By Gregory Cooper | Kuper Sotheby's International Realty | Austin, Texas

When a business owner signs a commercial lease, one of the first things the landlord asks for is a security instrument. Not a security deposit — something bigger. The landlord has just committed to spending real money on your build-out before you've paid a single month of rent, and they want to know they can recover that investment if things go sideways. Two instruments come up almost every time: a personal or corporate guarantee and a standby letter of credit. They sound similar. They work very differently.

For growing businesses — fitness concepts, emerging brands, first-location operators — this question comes up early and often, because the landlord's financial requirement will outpace what a young company can show on paper. Understanding your options is the first step to negotiating a structure that protects you as much as it protects them.

Option A: The Personal or Corporate Guarantee

A guarantee is a written legal promise. It says: "If the tenant doesn't pay what it owes, I will." No money changes hands at signing. The guarantor — whether that's the business owner, an investor, or a corporate parent — signs a document that gives the landlord the legal right to come after them directly if the tenant defaults.

What it costs you up front: Nothing. That's the appeal. You sign it, you walk away, and there's no cash leaving the room. The exposure is real — if the landlord ever wants to enforce it, they can — but enforcement requires a lawsuit. They have to file, win, and then pursue collection. That process takes months to years, and it costs the landlord legal fees to get there.

What it doesn't do: It doesn't cap your exposure unless the lease specifically says so. An unlimited, unconditional personal guarantee — which is what landlords ask for by default — exposes the guarantor to every dollar of unpaid rent for the rest of the term, plus damages, legal costs, and build-out costs. On a ten-year lease, that number can be very large. The guarantee needs to be negotiated, not just signed.

Option B: The Standby Letter of Credit

A standby letter of credit is a different animal entirely. It's issued by a bank — not the tenant, not the investor, the bank itself — and it's the bank's own unconditional promise to pay the landlord a specific amount of money if the landlord presents a written demand.

No lawsuit. No grace period. The landlord hands the bank a letter, and the bank pays within a matter of days. Then the dispute — whether the draw was justified, whether the tenant actually owed that money — gets sorted out afterward, after the funds have already left the building.

What it costs you up front: Two things. First, the investor or guarantor must either hold cash collateral at the bank equal to the full LOC amount, or have a credit facility large enough to support it. That cash is effectively frozen — it can't be deployed elsewhere — for as long as the LOC is outstanding. Second, banks charge an annual fee to issue and maintain an LOC: typically 0.75% to 2.00% of the face amount per year.

Side by Side

The right answer in any negotiation is to lead with the guarantee and push hard to keep it. If the landlord insists on an LOC, the structure below limits how much capital has to be tied up — and for how long.

Why the Security Should Burn Down Over Time

Here's the thing about lease security instruments: the landlord's actual risk isn't flat over time. On Day 1, they've spent real money — tenant improvement allowance, leasing commissions — and collected nothing. That's their highest point of exposure. By Year 3 or 4, rent payments have been flowing in long enough to recover most of what was spent. By Year 5, the business has a track record and the landlord's investment is largely amortized through rent.

Keeping the full security in place through Year 8 or 9 would give the landlord a windfall if they ever drew on it — far more than they actually lost. The solution is a burn-down structure.

How it works: The security instrument starts at the landlord's total cost — TI allowance plus verified leasing commissions. It holds at the full amount through the end of Year 1, protecting the landlord during the period of highest exposure. Then, beginning on the first anniversary of rent commencement, it steps down by an equal amount each year until it reaches zero after Year 5. From that point forward, the obligation is fully extinguished.

Using $200,000 as a round illustrative figure:

• Year 1: $200,000
• Year 2: $150,000
• Year 3: $100,000
• Year 4: $50,000
• Year 5+: $0 — fully extinguished

If the LOC route is used, the bank releases the remaining collateral each year as the face amount steps down — so the investor's frozen cash comes back in annual installments. If the guarantee route is used, the guarantor's exposure simply declines by contract.

Who Provides the Security Doesn't Have to Be You

For growth-stage businesses, a common and entirely acceptable structure is to have a third-party investor — not the operating company — provide the guarantee or the LOC. This keeps the business's balance sheet clean and gives the landlord a creditworthy backstop they can underwrite. Landlords see this regularly from emerging brands, franchise operators, and venture-backed concepts. It's not a red flag; it's just how these deals get done.

The burn-down structure makes it even more attractive for investors: they know exactly what their maximum exposure is on Day 1, they know it decreases every year, and they know precisely when the obligation ends. That's a meaningful difference from an open-ended guarantee with no defined ceiling or sunset.
