Collecting Tenant Estoppels Before Closing: Timeline, Deadlines and What Happens When Tenants Don't Respond

Short answer: Collecting tenant estoppels for a sale or refinance is a timed project. Start from the closing date and the buyer's or lender's requirements, check each lease's estoppel clause for its response period and non-response terms, then send pre-filled certificates timed to the deal's dating rules. Track every tenant, follow up as each lease requires, and resolve discrepancies before closing.

A multi-tenant property is under contract, and closing is set for six weeks out. The buyer needs signed estoppel certificates, but not from every tenant. Its purchase agreement sets a threshold based on rentable area and a rule about how recent each certificate must be. Some leases give tenants 10 days to respond, some 10 business days, and a few say nothing. Two tenants have disputes with the landlord. One anchor tenant accounts for a third of the building.

Whether the deal closes on time can depend on how this process is run. This guide covers the estoppel process from the landlord's and property manager's side: the timeline, the documents that set the rules, what happens when tenants don't respond, and how to handle certificates that come back with changes.

The Estoppel Timeline at a Glance

This example uses a sample purchase agreement clause that requires certificates dated no earlier than 10 business days before closing and delivered at least 5 business days before closing. Your deal's terms may differ, so build the timeline from your own documents.

The dating window. Under a clause like this one, a certificate signed more than 10 business days before closing may be too old, but certificates must be delivered at least 5 business days before closing. That leaves a narrow window for tenants to sign. Leases may give tenants 10 days or more to respond, so a request sent too early can come back stale, and one sent too late can miss delivery. Check whether the purchase agreement lets early certificates be re-dated or updated.

Step 1: Read the Three Sets of Rules

Three sets of documents decide how the process runs. Read them before sending anything.

1. The purchase agreement or loan terms. These set what the buyer or lender needs:

• the required form

• which tenants must return certificates

• the closing threshold

• how recent each certificate must be

• the delivery deadline

Thresholds may be based on area, not tenant count. The sample purchase agreement clause used in this guide requires estoppels from tenants occupying at least 75% of the rentable area.

2. Each lease's estoppel clause. This sets what the tenant owes:

• the response period

• whether the lease has its own attached form

• what the tenant must certify

• what happens if it doesn't respond

A buyer's form may ask for more than a lease requires, and tenants may be able to decline to certify matters outside their obligation.

3. Any notice requirements in the lease. Requests may need to go to a specific address, by a specific method, to count as delivered. A request sent the wrong way may not start the response clock.

Step 2: Build the Tracker

At portfolio scale, the tracker shows whether you're on course to meet the closing condition. Keep one row per tenant:

Prioritize by area. When the threshold is based on rentable area, a few large tenants may carry most of it. Send to them first and follow up hardest with them, because one missing anchor certificate can decide whether the threshold is met.

Step 3: Pre-Fill and Verify Each Certificate

Pre-fill every certificate from current records, then check each line against its source before sending. An error a tenant signs can become the fact the buyer or lender relies on. Pulling rent, deposit and paid-through figures from the same ledger that holds each tenant's lease and payment history reduces transcription errors across dozens of certificates.

Deposit balances are one of the lines most likely to need checking. Following a consistent process for security deposit accounting makes this line faster to verify. Have someone other than the preparer review each draft.

Step 4: Time the Send Date

Work backward from the delivery deadline and the dating window:

1. Start from the date certificates must be delivered.

2. Note the earliest date a certificate can be signed and still be recent enough.

3. Allow for each lease's response period and any follow-up or second notice.

4. Send so that tenants are likely to sign within the window.

Include the lease clause and the response deadline in the request, along with a contact for corrections. Log the date and method of delivery for every tenant.

Step 5: Follow Up by the Lease's Rules

When a response date passes, follow the lease's process exactly, including any second notice it requires. Some leases only treat non-response as a default, or allow deemed answers, after a follow-up notice and a further period. Skipping a required step can weaken any reliance on those terms later.

When Tenants Don't Respond: Deadlines and Deemed Answers

Each lease's estoppel clause decides what non-response means. The examples below come from leases filed with the SEC. They show what a lease may contain, not a general rule.

• Response periods. Commercial leases may specify periods such as 10 days or 10 business days after the landlord's written request. One lease filed with the SEC gives the tenant 10 business days to certify, among other things, the commencement date, that the lease is unmodified and in effect, the date through which rent has been paid, and whether the landlord is in default.

• Deemed answers. Some clauses treat certain facts as conclusive if the tenant doesn't respond in time. The same lease provides that failure to deliver the statement is conclusive that:

  • the lease is in full force without modification, except as represented by the landlord,

  • there are no uncured landlord defaults, and

  • no more than one month's rent has been paid in advance.

  It also makes late delivery an immediate tenant default.

• Second notices. Other leases add a step. In one, the landlord can send a follow-up notice, and failure to respond within five days of it becomes a default.

• Signing on the tenant's behalf. Some leases expressly authorize the landlord to sign or deliver an estoppel on the tenant's behalf if the tenant fails to respond. In one example, the lease appoints the landlord as the tenant's attorney-in-fact for that purpose after a 10-day deadline passes.

• What this means in practice. Deemed-answer provisions can help, but buyers and lenders often still want a signed certificate, and how these clauses are enforced depends on the lease and the jurisdiction. For tenants that count toward the closing threshold, keep pursuing a signed certificate and tell the buyer or lender early if one is at risk.

When Certificates Come Back With Changes

Returned certificates can include changes. Log each one and resolve it before closing where possible, because an unresolved exception becomes the buyer's or lender's question.

Don't pressure a tenant to sign a certificate it believes is wrong. A corrected certificate that states the real position is more useful than a clean one that turns out to be inaccurate. If a change reflects a real change to the deal, document it as a lease amendment rather than through the certificate. Afterward, update the ledger, lease file and dates so the same gap doesn't appear in the next request.

If the Closing Date Moves

A delayed closing can push certificates outside the dating window. When the date moves:

• Recalculate the window for every certificate.

• Check whether the purchase agreement allows certificates to be updated or re-dated, and on what terms.

• Identify which tenants may need to re-sign, starting with those that count most toward the threshold.

• Update the tracker with new deadlines.

After closing, the new owner or manager takes over the tenants. The property management takeover plan covers what happens next.

For Tenants: What the Deadline Means for You

If you're a tenant who has received an estoppel request:

• Check your lease's estoppel clause for the response period and what you must certify.

• Respond on time. Under some leases, missing the deadline can mean certain facts are treated as confirmed, or can become a default.

• Correct anything inaccurate and state any known claims, such as unfinished landlord work or unpaid allowances, rather than signing a certificate you believe is wrong.

• Check what you're asked to certify. A buyer's form may go beyond what your lease requires.

• Get advice on any certificate you're unsure about before signing.

Checklist

• Purchase agreement or loan terms read: form, tenants, threshold, dating rule, delivery deadline

• Every lease's estoppel clause read: response period, form, scope, non-response terms

• Notice requirements confirmed for each lease

• Tracker built, with rentable area and % of threshold per tenant

• Certificates pre-filled from current records and verified line by line

• Each draft reviewed by someone other than the preparer

• Send date timed to the dating window and response periods

• Delivery date and method logged for every tenant

• Follow-up and second notices sent according to each lease

• Every returned certificate reconciled with your records

• Discrepancies resolved or disclosed before closing

• Records updated after corrections

• Certificate set delivered before the deadline

Common Mistakes

• Sending before reading the deal terms. Certificates sent without checking the dating rule can come back too old to use.

• Counting tenants instead of area. Under an area-based threshold, a missing anchor certificate can matter more than ten small ones.

• Skipping required notice steps. Relying on deemed answers without following the lease's notice process can weaken that reliance.

• Relying on deemed answers for key tenants. Buyers and lenders often want signed certificates, whatever the lease says about non-response.

• Leaving discrepancies for the buyer. Unresolved changes become closing questions.

• Not recalculating when closing moves. A delayed closing can make certificates stale.

Frequently Asked Questions

1. How long does the tenant estoppel process take?
It depends on the deal's deadlines, the number of tenants and each lease's response period. Work backward from the delivery deadline, allowing time to verify drafts, for tenants to respond, for follow-up, and to resolve discrepancies.

2. How long does a tenant have to sign an estoppel certificate?
Whatever the lease says. Commercial leases may specify periods such as 10 days or 10 business days after the landlord's written request.

3. What happens if a tenant doesn't sign an estoppel certificate?
It depends on the lease. Some leases treat certain facts as confirmed, some make non-response a default, sometimes after a second notice, and some authorize the landlord to sign on the tenant's behalf. Buyers and lenders often still want a signed certificate.

4. Can a landlord sign an estoppel certificate on the tenant's behalf?
Only if the lease allows it. Some leases expressly appoint the landlord as the tenant's attorney-in-fact for this purpose if the tenant fails to respond.

5. Do all tenants have to return estoppel certificates before closing?
Not always. Purchase agreements may set a threshold instead, such as tenants occupying a minimum share of the rentable area. Check the deal's terms.

6. How recent does an estoppel certificate need to be?
It depends on the purchase agreement or loan terms. In one sample clause, certificates must be dated no earlier than 10 business days before closing.

7. What if a tenant changes the certificate before signing?
Log the change, check it against your records, and resolve it before closing where possible. If it reflects a real change to the deal, document that change separately rather than through the certificate.

8. What happens to estoppels if the closing date moves?
Certificates may fall outside the dating requirement. Check whether the purchase agreement allows them to be updated or re-dated, and identify which tenants may need to re-sign.

Conclusion

Collecting tenant estoppels before closing is a timed project with fixed rules. Read the deal terms and every lease's estoppel clause first, build a tracker that measures progress toward the closing threshold, verify every certificate before it goes out, time the send date to the dating window, follow each lease's notice process, and resolve discrepancies before they reach the buyer or lender. Run that way, the estoppel set supports the closing rather than delaying it.
