How to review an estoppel certificate against the lease and rent roll

In short: check every statement in a tenant estoppel against two sources: the lease with all its amendments, and the tenant’s row on the rent roll. Work out the rent in force on the certificate’s date, then compare the dates, area, share, deposit and options. Set apart what only the tenant can state, such as defaults, offsets and prepaid rent, and turn each difference into an item to settle before closing.

What does an estoppel certificate certify?

A tenant estoppel certificate is a signed statement from the tenant, usually requested by the landlord for a buyer or lender. It confirms the lease’s key facts as of a date: that the lease is in force, which documents make it up, the rent, dates, deposit and options, and whether either side is in default. Many leases require one on request within a set time; the fictional Harborview Tower sample lease allows ten business days (§23.2, p. 7).

Why does an estoppel bind?

The certificate is addressed to the people who will rely on it; the sample’s tenant certifies “knowing that they will rely on this certificate”. That reliance gives it force: a tenant that certified a fact to a buyer or lender who relied on it will generally find it hard to argue the opposite later.

For the buyer, the point is timing. Find a wrong statement before closing, while the seller can still correct it, credit it or hold money back. How far a certificate binds depends on its wording and the governing law; this guide is not legal advice.

What should you check on an estoppel?

How do you tie each statement to the lease?

1. Start with the documents. List the lease and everything that changes it. Amendments override the base lease, so check against the terms as amended.
2. Work out the rent on the certificate’s date. Find the rent schedule step that contains it, as in a rent roll tie-out.
3. Place the date in the lease’s timeline. Work out which deposit reductions, abatements and allowance deadlines have passed by the certificate’s date.
4. Quote the clause for each match or difference, so the reader can see what “matches the lease” rests on.

Then tie it to the rent roll

Buyers and lenders underwrite from the rent roll, so each certified figure should also match the tenant’s row.

• If the certificate and the lease agree but the rent roll doesn’t, correct the rent roll.
• If the certificate and the rent roll agree but the lease doesn’t, ask why. There may be an amendment or side letter you haven’t seen.
• If the certificate differs from both, it needs correcting or explaining before anyone relies on it.

What can only the tenant state?

Some statements can’t be checked against the lease or the rent roll:

• that the landlord isn’t in default
• that the tenant has no defenses, offsets or credits against rent
• the date rent is paid through, and that none is prepaid (the landlord’s ledger can confirm this; the lease can’t)
• that there are no agreements beyond the documents listed
• disputes or unpaid landlord obligations the tenant knows about

These are much of the reason the certificate exists. Keep them apart from the checked statements, and follow up every exception the tenant writes in.

A worked example

The fictional Northwind Analytics estoppel for Suite 1200 of Harborview Tower is dated October 5, 2026 and addressed to the landlord and a purchaser. Checked against the office lease and the building’s October 1, 2026 rent roll:

The certificate also says the lease hasn’t been amended. The file holds no amendment, but only the tenant can confirm there is nothing else. Three items need resolving:

• The deposit. $120,350.00 is what the deposit falls to on the first day of the 37th month of the term (July 1, 2028), if there has been no default. On October 5, 2026 the lease still requires $180,525.00, as the rent roll shows. The $60,175.00 gap is either an error on the certificate or a reduction no document in the file supports. Confirm what the landlord holds before the deposit is credited at closing.
• The rent roll. The certificate and the lease agree on $61,980.25 a month; the rent roll still carries the first year’s $60,175.00, understating the suite by $21,663 a year.
• The allowance. The tenant says $42,000.00 of the allowance it requested on May 20, 2026 is unpaid, and keeps it as its one exception to having no offsets (paragraph 8). The request came before the lease’s deadline of 12 months after commencement (July 1, 2026), so the forfeiture clause doesn’t defeat it. Only the landlord’s records can show whether it was paid.

How do discrepancies become closing items?

For each difference, record:

• the statement, quoted from the certificate, with its paragraph number
• what the lease says, with the clause and page, and what the rent roll shows
• the amount at stake
• who has to act: the seller, the tenant or the property manager
• how it will be resolved: a corrected certificate, a corrected rent roll, a closing credit or a holdback

In the example, that means evidence of the deposit held or a corrected certificate, a corrected rent roll, and either proof the $42,000.00 was paid or a credit or holdback for it. If you need a corrected certificate, allow for the time the lease gives the tenant. Keep the list with the deal’s other diligence items, so nothing closes on an open question.
