A letter of credit is a bank’s promise to pay. When used as lease security, it replaces or supplements the traditional cash security deposit with a financial instrument issued by the tenant’s bank in the landlord’s favor. If the tenant defaults, the landlord presents a demand to the bank and gets paid, usually within days. No lawsuit, no waiting, no argument about damages.
Letters of credit are most common in commercial leasing, especially for large spaces, long terms, and tenants whose credit is thin but whose banking relationships are strong. Startups with venture funding, foreign companies entering a new market, and growing businesses all use them. For landlords, a letter of credit is often better than cash. For tenants, it preserves working capital but comes with costs and risks that deserve a close look.
How a Lease Letter of Credit Works
The mechanics involve three parties. The tenant, called the applicant, asks its bank to issue the letter of credit. The bank, called the issuer, promises to pay the landlord, called the beneficiary, up to a stated amount if the landlord presents the required documents. The documents are usually simple: a written demand stating that the tenant has defaulted under the lease.
The key feature is that the bank’s obligation is independent of the lease dispute. This is called the independence principle. If the landlord presents a conforming demand, the bank pays, even if the tenant insists it did not default. The tenant’s remedy is to sue the landlord afterward to get the money back. The bank does not adjudicate who is right.
Sight drafts and evergreen clauses
Most lease letters of credit are payable on sight, meaning the bank pays promptly when the landlord presents the demand documents. Many also include an evergreen clause, which automatically renews the letter of credit each year unless the bank gives advance notice of non renewal. Landlords insist on evergreen language so the security cannot quietly expire mid lease. Tenants should make sure the lease requires the landlord to accept a replacement letter of credit or return to a cash deposit if the bank declines to renew.
Why Landlords Prefer Letters of Credit
From the landlord’s perspective, a letter of credit solves several problems at once. Cash deposits can get tied up in bankruptcy proceedings if the tenant files. A letter of credit, because it is the bank’s independent obligation, is generally not considered property of the tenant’s bankruptcy estate. The landlord can draw on it even after a bankruptcy filing, which is a major advantage.
Letters of credit are also cleaner to administer. There is no commingling of funds, no disputes about interest on deposits, and no argument about the condition of the premises at draw time. The landlord presents the demand and receives the money. For institutional landlords managing many tenants, that simplicity has real value.
Why Tenants Agree to Them
Tenants agree to letters of credit mainly to preserve cash. A large cash security deposit locks up working capital for the entire lease term, sometimes years. A letter of credit ties up a credit line instead, leaving cash free for operations, inventory, and growth. For a startup burning venture money on expansion, that difference can matter enormously.
Letters of credit can also unlock deals that would otherwise not happen. A tenant with weak credit but a strong bank relationship can offer a letter of credit as a substitute for the massive cash deposit a landlord would otherwise demand. It functions as a credibility bridge, letting the deal proceed while the tenant builds a track record. Tenants with bad credit who still need to get approved will recognize the same logic at a smaller scale.
The Costs Tenants Often Underestimate
A letter of credit is not free. The bank charges an issuance fee, typically a percentage of the face amount per year, plus renewal fees for evergreen instruments. On a five hundred thousand dollar letter of credit at one and a half percent annually, the tenant pays seventy five hundred dollars a year for the privilege of posting security. Over a ten year lease, that is real money.
The bigger cost is the credit line impact. The bank treats the letter of credit as an outstanding obligation and reduces the tenant’s available borrowing capacity by the full face amount. A tenant who needs that credit line for operations may find the letter of credit constraining in exactly the wrong way. Before agreeing, ask your banker how the instrument affects your covenants and availability, not just what the fee is.
Collateral requirements
Banks often require the tenant to post collateral for the letter of credit, sometimes cash equal to the full face amount. If that happens, the tenant has achieved nothing: the cash is locked up anyway, plus the tenant is paying bank fees on top. Negotiate with the bank for a partially secured or unsecured letter of credit based on your overall relationship, and get the collateral terms in writing before the lease is finalized.
Negotiating the Letter of Credit Provisions
The lease language governing the letter of credit deserves as much attention as the rent. Start with the draw conditions. The lease should specify exactly what documents the landlord must present and what statement of default it must make. Vague draw language invites abuse. Ideally, the landlord must certify a specific monetary default, not just a general breach.
Next, negotiate a burn down or reduction schedule. Many leases allow the letter of credit amount to decrease over time as the tenant proves reliable. A one million dollar letter of credit might step down to seven hundred fifty thousand after two years of on time payments, and to five hundred thousand after four. This recognizes that the landlord’s risk declines as the tenancy matures. Landlords resist this, but it is a standard ask.
Also address replacement and return. The lease should say what happens if the issuing bank’s credit rating drops below a threshold, who pays for a replacement, and how quickly the original is returned after the lease ends. A letter of credit that lingers for months after move out continues to tie up your credit line for no reason.
Finally, compare the letter of credit against the alternative. A traditional security deposit versus other upfront amounts analysis should include the bank fees, the credit impact, and the bankruptcy advantage. Sometimes cash is cheaper. Run the numbers both ways.
What Happens When the Landlord Draws
When a landlord draws on a letter of credit, the bank pays first and asks questions never. The tenant usually learns about the draw after the fact. This is by design. The independence principle means the bank is not a referee.
The tenant’s recourse is against the landlord. If the draw was wrongful, because no default occurred or the amount was wrong, the tenant sues the landlord for breach of the lease. This is cold comfort when the money is already gone, which is why the draw conditions in the lease matter so much. Tight draw language is the tenant’s main protection against a wrongful draw.
Tenants should also know that most leases require the tenant to replenish the letter of credit after a draw. If the landlord draws two hundred thousand from a one million dollar instrument, the tenant must restore it to the full amount within a set number of days. Failure to replenish is itself a default, creating a spiral that struggling tenants should take seriously.
Alternatives Worth Considering
A letter of credit is not the only way to secure a lease. A larger cash deposit is simpler and cheaper if you have the cash. A cosigner or guarantor with strong credit can substitute for funded security in some deals. A surety bond, where a bonding company guarantees your performance, works similarly to a letter of credit but through a different industry.
Each alternative has its own cost structure. Cash costs you liquidity. A guarantor costs you a relationship and leverage. A surety bond costs premiums and underwriting hassle. The letter of credit sits in the middle: professional, bank backed, and expensive in ways that are easy to overlook. Match the security to your actual financial situation rather than defaulting to whatever the landlord’s form lease proposes.
The Bottom Line
Letters of credit are powerful lease security because they give landlords fast, bankruptcy remote access to money. For tenants, they preserve cash at the price of bank fees, reduced credit capacity, and the risk of a wrongful draw with limited immediate recourse. Negotiate the draw conditions, push for a burn down schedule, and make sure your bank’s collateral demands do not defeat the purpose. Used wisely, a letter of credit is a smart financing tool. Used carelessly, it is an expensive way to post a deposit you could have just paid.
