The conversation about security structures at lease signing almost always feels like a formality. The tenant is excited about the space, the landlord is glad to have it filled, and negotiating the security deposit is the last administrative hurdle before everyone moves on. So the structure often gets less attention than it deserves.
And then something unforeseen happens — and it turns out the security structure was one of the most important decisions made in that transaction.
What's at Stake
A commercial lease is a long-term commitment. A five- or ten-year lease with a retail or office tenant represents a significant amount of future cash flow. If that tenant defaults — especially early in the term — the owner faces the worst-case combination: lost rent, legal costs, potential build-out write-off, and the cost and time of re-leasing. The security structure doesn't prevent default, but it substantially affects how bad the outcome is if default happens. Getting this right at the front end is one of the most meaningful ways to protect the investment.
The Three Main Structures
Cash security deposits are the most common and simplest to understand. The tenant puts up a defined amount — typically tied to some number of months' rent — which the landlord holds and can draw on if the tenant defaults or fails to leave the space in the required condition. The advantage is simplicity and immediacy: if there's a claim, you have funds. The limitation is that cash deposits are typically capped in negotiation, and a large cash deposit ties up real money for the tenant in ways that can create friction — or cause well-qualified tenants to push back hard.
Letters of credit are a different mechanism — and in many commercial contexts, especially larger transactions, they're the better tool. A letter of credit is issued by the tenant's bank and allows the landlord to draw funds directly from the bank upon presenting specified documentation of default. The key advantage: the letter of credit is not the tenant's asset, so it typically survives a bankruptcy filing in ways a cash deposit might not. For larger tenants or longer-term leases, this can be a meaningful distinction. Letters of credit do require the tenant to have the banking relationship and creditworthiness to obtain one, and they involve more documentation and process than a cash deposit. But for the right deal, they're worth the friction.
Personal guaranties are another layer entirely — the owner's ability to pursue the business principals personally if the entity defaults. For a new business, a business with limited operating history, or a thinly capitalized entity, a personal guaranty significantly changes the risk calculus. An owner holding a guaranty from principals with real personal assets has meaningful recourse beyond the lease. Guaranties can be full (covering all obligations) or limited (covering a defined amount or time period). What makes sense depends on the tenant's profile, the owner's leverage in negotiation, and the specific deal.
The Burndown Conversation
In longer leases, it's common for the security structure to "burn down" over time — the required deposit or letter of credit amount decreases after a defined period of satisfactory performance. This is a reasonable commercial accommodation, and it gives tenants an incentive for consistent performance.
The structure of a burndown schedule matters. Burning down too fast, or before the tenant has demonstrated real staying power, can leave the owner exposed in years two and three of a lease — when some of the highest-risk situations arise. We work with our owners to think through these schedules at the lease stage rather than accepting whatever is proposed as standard. There's usually room to negotiate, and the specific structure should reflect the specific tenant's risk profile.
Planning for the Unforeseen
Here's the honest truth about commercial tenants: businesses fail. Industries shift. A tenant who signed a lease in good faith during strong conditions can find themselves genuinely unable to perform when conditions change. This isn't always bad faith — sometimes it's just the reality of operating a business.
The security structure won't fix a failed tenant. But it can be the difference between a painful situation and a catastrophic one. And how you handle the default process — documented, prompt, consistent, legally sound — determines how much of that protection you actually get to use. We've seen owners with strong security structures recover meaningful amounts after a default and re-lease with minimal long-term damage. We've also seen owners with weak structures or poorly documented claims absorb losses they couldn't recover from.
Coordinating with the Right Advisors
I want to be clear: the specifics of security structures, guaranty enforceability, and bankruptcy implications in commercial leases are legal questions. Every significant lease should involve a commercial real estate attorney, full stop. The structures described here are concepts — how they work in a specific North Carolina lease, with a specific tenant, under specific circumstances, is your attorney's territory. What we bring is operational context: we've seen what these structures look like when they're put to the test, and we can flag the patterns that tend to create problems down the road. We connect our owners with qualified counsel early — before the lease is signed, not after a problem emerges.
The Bottom Line
Security deposits, letters of credit, and personal guaranties are not administrative boxes to check. They're part of your risk architecture as a commercial property owner. Getting them right at the front end is one of the highest-leverage things you can do before a tenant takes occupancy. If you're underwriting a new tenant relationship or reviewing your current lease structure, we're happy to share how we think about these issues — and to make sure you're connected with the right advisors.
