Escrow Term

Estoppel Certificate

Estoppel certificates explained for apartment owners preparing for buyer due diligence.

By Don Favia · Updated July 3, 2026

Direct Answer

An estoppel certificate is a tenant-signed document that confirms key lease facts, such as rent, deposits, lease terms, and certain tenant claims. In an apartment sale, buyers use estoppels to confirm that the rent roll matches the tenancy facts.

Why It Matters

Estoppels reduce uncertainty during escrow. If the estoppels disagree with the rent roll, buyers may ask for more diligence, credits, price changes, or contract protections.

Tenant documentation can create legal issues. This is general information only. Owners should consult appropriate counsel for building-specific guidance.
