An estoppel certificate is a signed document in which a tenant confirms the current facts of their lease. It is usually requested by the landlord when a buyer or lender needs to verify that the lease terms and the rent roll are accurate.
The word “estoppel” comes from a legal principle that prevents someone from later taking a position that contradicts what they stated earlier. Once a tenant signs the certificate, they generally cannot later claim different terms against the party who relied on it.
What it typically includes
An estoppel certificate usually asks the tenant to confirm:
- The lease and all amendments, and that there are no side agreements
- Start and end dates, and any renewal or expansion options
- Current monthly rent and the date it is paid through
- The security deposit amount held by the landlord
- Whether any rent has been prepaid
- Whether the landlord or tenant is in default
- Any outstanding tenant improvement work or allowances owed
- Any rights of first refusal or purchase options
How it works
When a property is sold or refinanced, the buyer or lender gives the landlord a list of required estoppels. The landlord fills in the expected facts and sends the certificates to tenants, who review, correct if needed, sign and return them by the deadline in the lease. Any discrepancies between the certificate and the landlord’s records must be resolved before closing.
Why it matters for landlords
Estoppels protect buyers and lenders, but they also flag problems early. If a tenant says they paid a larger deposit than your records show, or claims an unrecorded rent reduction, you want to know before closing, not after. Keeping leases, amendments and tenant ledgers organized in one system, like TenantLoop leasing, makes it easy to prepare accurate certificates.

Where it gets confusing.
Does a tenant have to sign an estoppel certificate?
Only if the lease requires it, though most commercial leases do. These clauses usually set a deadline, such as 10 or 15 days, and may treat silence as confirmation of the landlord's version.
Are estoppel certificates used for residential rentals?
They are much more common in commercial real estate. Residential buyers and lenders usually rely on the rent roll and leases, though some larger multifamily deals request tenant estoppels too.
