Estoppel Certificates Are the Only Protection When No Lease Exists

Commercial properties with long-term tenants and zero signed leases appear in Lake Havasu City more often than most buyers expect. When that situation surfaces during due diligence, the estoppel certificate stops being a formality and becomes the only enforceable document confirming tenancy terms. 

The Reality of Properties With No Leases in Havasu Commercial Deals

Verbal month-to-month arrangements are not uncommon in small commercial markets. They appear most often in buildings that passed through estate sales or stayed in the same family for decades. They also show up where owners ran things on personal trust.

In those situations, the tenant pays, and the owner deposits the check. Nobody feels the need to ask for paperwork because the relationship has always worked on goodwill.

From the outside, the property looks stabilized. It has real tenants, and the rent flows in reliably. That makes it easy to check those items off on your due diligence checklist and move on.

But buyers need to understand they are buying into a handshake agreement. It's a month-to-month arrangement with no formal record of the deposit amount, the rent terms, or the notice period required to reclaim the space.

That gap is where post-closing disputes begin. In a standard transaction, a signed lease provides the necessary documentation. When no lease exists, something else has to fill the record.

The Value of an Estoppel Certificate in Commercial Real Estate

An estoppel certificate is a document the tenant signs directly. It confirms the material facts of their tenancy, including monthly rent, deposit amount, lease term or month-to-month status, notice period, and any special agreements.

Once the tenant signs, they are legally bound by what they certify. That gives the buyer and lender a reliable record they can use.

That binding effect is exactly what makes the estoppel so valuable. A tenant who signs one stating a month-to-month arrangement, a 30-day notice requirement, and a specific deposit amount cannot later claim otherwise. The buyer then takes title with that confirmation in hand, which provides real peace of mind at closing.

In a standard deal, the estoppel confirms what a written lease already states. When no lease exists, the estoppel becomes the entire record. It is the only document establishing the tenancy terms that both parties acknowledge. That distinction matters more than most buyers realize before they close.

When Estoppel Certificates Saved a Deal

Randy Shuffler has navigated commercial closings in Lake Havasu City and the Kingman corridor for over two decades. The goal is always the same: identify structural gaps before keys change hands. In the field, estoppels are standard practice on any commercial deal with tenants in place.

"When you do a commercial sale, you get the tenants signing an estoppel stating that they agree what the deposit is, the terms, everything. You always get estoppels on all commercial deals if there's tenants involved. I hadn't run into the tenants with no leases thing before." – Randy Shuffler, Founder and Commercial Real Estate Agent, Lake Havasu City Commercial at Realty ONE Group Mountain Desert

This was a case where the property had two tenants with years of occupancy. They were paying their rent every month. For practical purposes, that's a stabilized property. However, the owner didn't have a formal lease with either tenant.

The buyer decided to move forward with the estoppels covering the gap. But the honest read on that deal: a short written lease alongside each estoppel would have been worth pushing for. The estoppels served the purpose, but the combination removes all ambiguity and holds up better under scrutiny.

The practical facts worked in the buyer's favor. Rents were low, and the tenants had been in place for years. The buyer planned to deliver notices shortly after closing. An estoppel confirming month-to-month tenancy with 30-day notice terms put the buyer in a position to do exactly that, with documentation in hand.

What Buyers Should Look For on Any Tenant-Occupied Property

One direct question belongs early in every commercial due diligence process: do signed leases exist for every occupied space?

If the answer is no, estoppels become mandatory. Each tenant signs a certificate confirming the specific terms of their tenancy. That review happens during the due diligence window, before earnest money becomes non-refundable.

If a tenant refuses to sign, that is a red flag. It may signal a disputed term, an undisclosed side agreement with the seller, or a tenant who anticipates a problem. Treat the refusal as a negotiating point that puts the deal on hold until it's resolved.

Pairing the estoppel with a short-form written lease in any no-lease situation is the better approach. A basic month-to-month agreement with clear terms and a signature line creates a documented record that holds up in a dispute. It also supports future financing and gives the next buyer a cleaner path if the property trades again.

Arizona's commercial landlord-tenant statutes reinforce the same principle that Uniform Commercial Code standards establish at the national level. Written confirmation of tenancy terms controls over verbal representations in any dispute. That principle applies directly to the gap the estoppel fills.

Common Questions About Estoppel Certificates in Commercial Real Estate

What is an estoppel certificate in commercial real estate?

An estoppel certificate is a document a tenant signs to confirm the material facts of their tenancy. The details include monthly rent, deposit amount, lease term or month-to-month status, notice period, and any special agreements. Once signed, the tenant is legally bound by what they certify. That binding effect protects the buyer from conflicting claims after closing.

Does an estoppel certificate replace a written lease entirely?

An estoppel confirms current tenancy facts and binds the tenant to what they certify. It does not create ongoing lease obligations the way a written agreement does. In a no-lease situation, pairing the estoppel with a short-form month-to-month written lease creates a complete record. One document confirms current terms, and the other establishes enforceable obligations going forward. Together, the two documents are far stronger than either one alone.

Can a commercial deal close without leases if tenants are in place?

Yes, but risk exposure increases significantly. Without leases, the estoppel becomes the only written record of tenancy terms. Buyers who proceed without estoppels in a no-lease situation have no enforceable documentation if a dispute arises over rent. For a look at how this played out in a real transaction, read my post about a $700,000 deal that almost fell apart. It covers a deal involving a property with no leases and how it was salvaged using estoppel certificates.

What should a buyer do if a tenant refuses to sign an estoppel?

Treat the refusal as a red flag and a negotiating point. A refusal may signal a disputed term, an undisclosed agreement with the seller, or a tenant anticipating a post-closing problem. Do not proceed without resolving the underlying issue. The refusal itself tells you something material about the tenancy.

How is a verbal month-to-month tenancy different from a written lease in terms of buyer risk?

A verbal arrangement leaves no enforceable written record of rent amounts, deposit figures, or notice periods. Those terms exist only in memory, meaning any dispute defaults to conflicting recollections with nothing to adjudicate against. The buyer who inherits that arrangement without an estoppel has no written ground to stand on.

When should estoppel review happen in the due diligence process?

The review should happen before the purchase agreement goes hard on earnest money. Request, execute, and review estoppels during the inspection and due diligence window. Discovering material discrepancies after earnest money becomes non-refundable strips the buyer of leverage. This timing discipline applies regardless of whether signed leases exist.

How does a no-lease tenancy affect financing for the acquisition?

Most commercial lenders require documented tenancy as part of their underwriting for income-producing properties. Verbal arrangements typically do not satisfy that requirement. A lender reviewing a building with no written leases and no estoppels may decline the loan or require documentation before funding. Buyers planning to finance the acquisition need to resolve the documentation gap before the loan application, not after.

Does the estoppel protect the buyer if a tenant later claims a larger security deposit?

Yes, a tenant who signs an estoppel certifying a specific deposit amount cannot later claim a different figure. The signed certificate is binding. That is the core protection the document provides. It closes the gap between what the seller represented and what the tenant can claim once the transaction closes.

Protect Your Deal Before the Keys Change Hands

When commercial tenants occupy a property without written leases, buyers need documented proof of the terms they inherit. Estoppel certificates establish what tenants acknowledge about rent, deposits, and notice periods. Without that documentation, buyers risk disputes they could have resolved before closing.
