Prepare estoppel certificates faster with Lextract. Extract rent, dates, deposits, and renewal terms from every lease. Populate estoppel templates with verified, structured data.
By Angel Campa, Founder · Updated March 2026
Estoppel certificates must accurately state the current terms of a lease — rent, expiration date, security deposit, outstanding landlord obligations, and any defaults. Preparing estoppels requires re-reading the entire lease plus all amendments to extract these specific data points. When a property is being sold or refinanced, dozens of estoppels may be needed simultaneously under tight deadlines. Errors in estoppel certificates can create binding legal obligations if the receiving party relies on inaccurate information.
Lextract extracts all estoppel-relevant fields from the lease and amendments in minutes — base rent, commencement and expiration dates, security deposit amounts, TI allowance details, renewal options, and outstanding obligations. This structured data can be used to populate estoppel certificate templates quickly and accurately. Instead of re-reading each lease to fill out the certificate, administrators simply transfer verified extracted data into the estoppel form.

Lextract extracts the data needed to populate an estoppel certificate — it does not generate the legal document itself. The structured extraction provides all the key data points (rent, dates, deposits, options) that go into a standard estoppel form, making the population step fast and accurate.
The most critical estoppel fields are current base rent, rent commencement date, lease expiration date, security deposit amount and type, TI allowance details, renewal option terms, and any outstanding landlord work obligations. Lextract extracts all of these.
