Estoppel Certificates and SNDAs: A Guide for Landlords

A refinance is set to close at the end of the month. The lender’s checklist calls for a signed estoppel certificate from each major tenant, confirming the facts of its commercial lease, plus an SNDA from the same tenants. Two weeks out, the second-largest tenant returns its certificate with two notes in the margin: the landlord still owes part of the improvement allowance, and the tenant reserves its right to audit last year’s operating expense reconciliation. Another tenant signed its SNDA, but nobody notarized the signature, so the title company cannot record it.

None of these problems started in the closing week. The allowance balance was in the ledger, the audit notice in the file, the notary rule on the recording office’s checklist. The estoppel round only exposed them when there was the least time to fix them.

This guide covers estoppels and SNDAs from the landlord’s side: what tenants confirm, how the lease controls the request, how to prepare, reconcile and track certificates, how to handle edits, and how SNDAs and recording work in DC, Virginia and Maryland. Estoppel and SNDA preparation is part of Levaru’s lease administration service, and this is the method behind it. It is general information, not legal advice; the lease and your counsel control.

What is an estoppel certificate in a commercial lease?

An estoppel certificate is a signed statement in which a tenant confirms the key facts of its lease as of a stated date, for a buyer or lender who will rely on it. It tests what the landlord has said: that the lease exists, reads as described, and hides no disputes.

The name comes from estoppel, a legal doctrine that can stop a party from later asserting facts that contradict a statement another party reasonably relied on. A tenant that certifies “no landlord defaults” may find it hard to raise an earlier default against the buyer or lender that relied on the certificate. How far a particular certificate binds depends on its wording, the lease, the facts and the state’s law. That is a question for counsel, not for a form.

Three features matter most to a landlord:

• It is a snapshot. It speaks as of its date. A missed payment or new dispute after that date is not covered, which is why buyers and lenders care how old a certificate is.
• It runs to named parties. It names the buyer or lender, often with successors and assigns. A certificate addressed to the wrong entity may need to be redone.
• It confirms; it is not meant to amend. When a certificate and the lease disagree, someone has made an error. Fix it before signing, not after closing.

What does a tenant estoppel certificate usually confirm?

Most certificates cover the same core facts. The table shows the common items, where the landlord should source each one before pre-filling it, and what tends to go wrong.

Item	Tenant confirms	Landlord’s source	Common trap
Lease documents	Lease, every amendment, side letter, memo	Lease file, abstract	Side letter missed
Premises	Suite, floor, rentable area	Abstract, remeasurement	Area changed by expansion
Term and dates	Commencement, rent start, expiration	Commencement memo	Estimated dates never updated
Base rent	Current rent, next step	Abstract, billing	Step billed on wrong date
Additional rent	Expense share, base year, estimates	Billing, expense file	Share differs from lease
Rent paid through	Paid-to date, no prepaid rent	Tenant ledger	Credits or prepayments left out
Security deposit	Cash amount or letter of credit	General ledger, LOC file	Reduced or expired LOC
Defaults	None by either party, or listed	Notice file	Unresolved complaints
Offsets and claims	No offsets, credits or claims	Correspondence	Pending audit or abatement claim
Options	Renewal, expansion, first offer or refusal, termination	Abstract	Lapsed option still listed
TI and landlord work	Allowance paid, work complete	Draw records	Allowance balance unpaid
Free rent	Abatement used and remaining	Abstract, billing	Remaining abatement omitted
Assignment, sublease	Tenant entity, any transfers	Consents file	Name changed by merger
Guarantor	Guaranty in effect, guarantor	Guaranty	Guaranty burned off

In a triple net lease, the additional rent rows carry more weight, because taxes, insurance and common area charges are a large share of what the tenant pays. The allowance row depends on the tenant improvement allowance terms, whose draw conditions and deadlines decide whether a balance is still owed.

Lender forms often add items the lease does not require. Whether the tenant must confirm them depends on the estoppel clause.

How does the lease’s estoppel clause control the request?

The estoppel clause decides what the landlord can ask for, how fast the tenant must answer and what happens if it does not. Read it before you promise a lender a date. Leases commonly set a response period, but there is no standard number of days. The lease controls.

Clause element	What to look for	Why it matters
Response period	Days, business or calendar, from what event	Sets the earliest real return date
Notice	Who may request; delivery method and address	A bad delivery may not start the clock
Frequency	Limit on requests per year	A second round may need goodwill
Form	Lease exhibit, “customary” form or lender form	Decides which extra items bind
Content limits	Facts only; knowledge qualifiers allowed	Narrows what you can insist on
Deemed certification	Silence confirms the landlord’s statements	Helps only if the lender accepts it
Attorney-in-fact	Landlord may sign for the tenant	Same: confirm lender acceptance
Remedy	Failure is a default, with or without cure	Leverage, but slow and adversarial
Reciprocity	Landlord must give estoppels too	Matters when the tenant finances

Two rules follow. Count the response period from proper delivery under the notice clause, not from the day someone emailed a PDF. And if the lender’s form asks for more than the lease requires, trim it to the lease or send it early enough to negotiate.

Deemed-certification and attorney-in-fact provisions are weaker in practice than on paper: they rest on the landlord’s own statements, and a buyer or lender may still insist on a signed certificate. All of these terms belong in the abstract; our commercial lease abstract guide shows where they go.

How should a landlord prepare estoppels for a sale or refinance?

Prepare from the documents, prove the numbers against the money, then send. Most of a good estoppel round is done before the first certificate goes out.

1. Get the requirements in writing. Which tenants, which form, who the certificate must name, how recent it must be at closing, and which tenants owe SNDAs. The purchase contract or loan commitment sets these, including whether a seller certificate can stand in for a missing one.
2. Abstract first. Verify each abstract against the full document set in date order: lease, amendments, side letters, commencement memos, consents and guaranty. A certificate drafted from a stale abstract repeats its errors under the tenant’s signature.
3. Reconcile to billing and the rent roll. Check every number against what was billed, paid and represented (next section).
4. Pre-fill accurately. Fill every blank the landlord can answer and list each lease document by title and date. Disclose known open items, such as an unpaid allowance or an open reconciliation year. A tenant that sees its issue already stated has less to edit.
5. Send under the notice clause. Right address, method and copy parties. Log the delivery date and compute the due date from it.
6. Call early. An early call finds out who has the certificate (often counsel) and whether the form is a problem.
7. Review every return against the abstract. Line by line. Log each edit as a variance until it is resolved.
8. Resolve and deliver. Agree corrections, explain remaining variances to the buyer or lender, and file executed originals.
9. Update the records. If a certificate exposed an error, fix the abstract and billing, not just the closing file.

Why must the estoppel match the abstract, the ledger and the rent roll?

Because the buyer or lender will compare them. The rent roll is what the landlord represented; the estoppel is what the tenant confirms. When they disagree, the landlord’s credibility suffers, and sometimes the price or loan amount does too.

Check	Compare	Flag if
Base rent	Abstract steps, billing, rent roll	Any of the three differ
Paid-through date	Tenant ledger, rent roll	Arrears or prepaid rent not shown
Recoveries	Lease share and base year, billed estimates	Share or base year differs
Reconciliation	Expense file, certificate	Open year or disputed true-up
Deposit	Lease amount, ledger, bank or LOC	Balances differ; LOC reduced
Allowance	Lease allowance, paid draws	Balance owed not disclosed
Abatement	Lease schedule, billing	Free rent used or still owed
Open requests	Service requests, “no default” line	Old unresolved complaints

An illustrative example: the abstract puts a rent step on each anniversary of commencement. The commencement memo set the commencement date later than the estimate, but billing applied the step on the estimated date, and the rent roll shows the higher figure. A tenant that notices will correct the rent and claim a credit. Fix billing and the rent roll first, issue the credit, then send a correct certificate.

If a reconciliation year is open or the tenant’s audit window is still running, say so; the CAM reconciliation guide covers timelines and backup. Check open repair requests too. A tenant that has chased a roof leak for months will not certify that the landlord is not in default. In a Levaru-managed building, tenant requests and their status sit in our CMMS, so this check is a filter, not an inbox search.

What edits do tenants make, and how should a landlord respond?

Expect edits. Many are useful, because they show you a problem before the buyer does. Respond to the substance, and never pressure a tenant to sign something it believes is wrong.

Tenant edit	Usual reason	Landlord response
“To tenant’s knowledge”	Cannot verify everything	Usually fine for defaults and claims
Lists a landlord default	Unresolved repair or service	Fix it, or record the disagreement
Reserves audit rights	Open reconciliation	Accept; disclose to buyer or lender
Shows unpaid allowance	Draws not yet paid	Confirm amount; credit or escrow
Corrects rent or dates	Abstract or billing error	Verify; fix the source records
Strikes lender items	Beyond the lease	Trim to the lease or negotiate
“Lease controls” sentence	Fear of amending the lease	Usually harmless if facts are right
Keeps offset rights	Claim in progress	Resolve the claim or disclose it
Adds an unwritten term	Oral promise or email	Check files; disclose or dispute

Clear each edit with the buyer or lender, not only with the tenant; their counsel decides what closes. Never trade an informal promise in an email for a signature, because that email can become the side agreement the next buyer finds. Document any concession as an amendment or a closing credit. Good tenant relations through the year also tend to show up as faster returns.

What is an SNDA, and what does each part do?

An SNDA, or subordination, non-disturbance and attornment agreement, is a three-party agreement among the tenant, the landlord and the landlord’s lender. It sets what happens to the lease if the lender forecloses.

Part	Tenant agrees	Lender agrees	Effect
Subordination	Lease ranks behind the loan	—	Lender’s lien comes first
Non-disturbance	—	Not to end the lease while tenant performs	Tenant keeps its space
Attornment	Recognize the new owner as landlord	—	New owner gets a paying tenant

Why lenders want them. A lender wants its loan to rank ahead of the leases, so a foreclosure is not tied to lease terms it never approved. It also values the rent. The SNDA gives it priority plus tenants who will recognize whoever takes title.

Why tenants want non-disturbance. Depending on state law and the documents, a lease junior to a mortgage can be at risk in a foreclosure. A tenant that has invested in its space wants a written promise that it stays while it performs.

Lender forms usually limit what a successor landlord takes on: no liability for the prior landlord’s defaults, no offsets against the prior landlord, no credit for rent paid well in advance, no amendments made without lender consent, and no liability for a deposit it never received. Tenants push back hardest where those limits meet an unpaid allowance or an offset right for landlord work, so start that negotiation early.

How does the lease’s subordination clause relate to an SNDA?

Commercial leases commonly address subordination already. The SNDA either confirms what the lease says or supplies what it left open. Three patterns are common:

• Automatic. The lease is subordinate to existing and future mortgages without another document, and the tenant signs confirming instruments on request.
• Conditional. The lease subordinates to a future mortgage only if the lender grants non-disturbance. The SNDA is the condition.
• Silent or outdated. The lease says little, or attaches a form that no longer fits lender requirements. Expect negotiation.

Priority is why this matters. A lease signed before a mortgage was recorded may rank ahead of it, so the lender may want the tenant to subordinate. Priority turns on recording and state law: a title and counsel question. Before promising a lender anything, check in the abstract which pattern each lease follows, whether the tenant must sign the lender’s form or only a “commercially reasonable” one, and which loans already have SNDAs.

Should an SNDA be recorded?

Often, yes. A lender or title company may want the signed SNDA recorded in the land records next to the mortgage. A document that misses the recording rules comes back and has to be signed again, so check the package before tenants sign: notarized signatures with complete acknowledgments, a legal description, and party names that match the record owner, the lender and the lease chain exactly.

The rules are local. Fairfax County’s circuit court, for example, requires a cover sheet for counter and mail recordings, notarized original signatures and minimum margins, per its recordation requirements. Get the recording-ready form from the title company or lender’s counsel first. Tenants with long terms or options sometimes also ask for a memorandum of lease, a short recorded notice that the lease exists.

What changes in DC, Virginia and Maryland?

The documents are the same across the region. Recording offices and statutes differ, and federal leases have their own rules.

Item	DC	Virginia	Maryland
Where SNDAs record	Recorder of Deeds (OTR)	Circuit court clerk, county or city	Circuit court land records
Statute to read	D.C. Code §§ 42-306, 42-401	Va. Code § 55.1-407	Md. Real Prop. § 3-101
Key point	Terms over 1 year need a deed	Possession alone is not notice	Estates above 7 years record

DC. The Recorder of Deeds, part of the Office of Tax and Revenue, keeps the District’s land records. D.C. Code § 42-306 requires a deed for an estate longer than one year, and § 42-401 makes a deed effective against later purchasers and mortgagees without notice only from its delivery to the Recorder for record.

Virginia. Va. Code § 55.1-407 makes listed unrecorded instruments void against purchasers for value without notice, and says mere possession of real estate is not, by itself, notice.

Maryland. Each county and Baltimore City has a land records department in the circuit court clerk’s office, per the Maryland Courts. Real Property § 3-101 requires recording for estates above seven years, exempts on stated conditions leases whose initial and renewal terms are each seven years or less, and allows a memorandum of lease instead. An unrecorded lease that should have been recorded stays valid against a later buyer with actual notice, or where the tenant’s occupancy gives reasonable notice.

Federal (GSA) leases. A GSA lease does not promise a commercial estoppel. Under its Statement of Lease clause (GSAR 552.270-24), the contracting officer issues a letter within 30 days of a joint written request from the lessor and a prospective lender or purchaser. Based on the lease file, it states only whether the lease is in full force, the date to which rent is paid in advance, and whether a default notice has issued. The subordination clause (GSAR 552.270-23) makes the lease self-operatively subordinate to recorded mortgages, commits the government to sign confirming instruments within 20 business days of a written demand, protects its lease rights while it is not in default, and deems it to have attorned after foreclosure. GSA rules call for clauses substantially like these in leases above the simplified lease acquisition threshold; read the lease you have. A sale also brings in novation: the GSA lease template (L100A) applies FAR subpart 42.12 to a transfer of ownership.

What is a landlord estoppel?

A landlord estoppel is the reverse: the landlord certifies lease facts for the tenant’s lender, buyer or assignee. It comes up when a tenant sells its business, assigns, sublets or refinances, and under ground leases, where the tenant’s leasehold lender relies on it. The lease may require one, often in a reciprocal clause.

The same discipline applies, because now the certificate binds the landlord:

• Reconcile before you certify “no amounts due.” An unbilled escalation or an unissued reconciliation may be hard to collect later if the certificate says nothing is owed.
• State tenant defaults. If the tenant is behind on an obligation, say so.
• Keep it to facts. Consents to assignment, landlord lien waivers and recognition agreements are separate documents and separate decisions.

How do you track estoppels and SNDAs through a closing?

Use one log per transaction, one row per tenant and a named owner for every row. It answers the “where are we?” that every party asks.

Column	Record	Why
Tenant and suite	Legal entity per lease chain	Wrong entity means a redo
Required	By loan, contract or neither	Focuses effort
Form	Lease exhibit, lender form, GSA letter	Sets content and timing
Sent	Date and method per notice clause	Starts the clock
Due	Computed from the clause	Sets follow-up dates
Owner	Person chasing this tenant	No orphan rows
Returned	Date signed and date received	Freshness at closing
Variances	Each edit, open or resolved	Shows closing risk
SNDA	Sent, signed, notarized, recorded	Recording readiness
Accepted	Buyer or lender sign-off	The real finish line

Give each row one status from a fixed ladder: not sent, sent, acknowledged, returned clean, returned with edits, resolved, accepted. Report status counts and every open variance with its owner on a fixed schedule, tightening it near closing. If closing slips, certificates can go stale against the contract or loan limit, so watch signing dates. In an investment sale, the same log becomes part of the diligence file.

Which mistakes cost closings?

Most estoppel problems are records problems that surface late:

• Drafting from the rent roll. It is a summary. Draft from the documents; check against the rent roll.
• Missing a document. An amendment signed under a prior owner, a side letter, or a consent that changed the tenant entity.
• Starting the clock wrong. An emailed request may not count if the lease requires courier delivery to a named address.
• Overloading the form. A lender form far beyond the lease, sent late, invites strikes with no time to negotiate.
• Unrecordable SNDAs. Missing notary blocks, legal descriptions or exact names mean a second signing round.
• Stale certificates. A slipped closing sends everyone back for bring-downs.
• Side promises. Concessions traded for signatures become undocumented lease terms.
• No loop back. Corrections that never reach the abstract and billing return in the next round.

Frequently asked questions

How long does a tenant have to return an estoppel certificate?

The lease decides. Commercial leases commonly set a response period in the estoppel clause, counted in business or calendar days from proper delivery under the notice clause. No single number applies to every lease. Federal tenants differ: under GSA’s Statement of Lease clause, the contracting officer responds within 30 days of a joint written request from the lessor and a prospective lender or purchaser.

Is an estoppel certificate legally binding?

It can be. Estoppel can prevent a tenant from later asserting facts that contradict what it certified to a buyer or lender who relied on the certificate. How far that reaches depends on the wording, the lease, the facts and the governing state’s law. Tenants should read every line against their documents, and landlords should never pre-fill anything they cannot support.

What happens if a tenant will not sign an estoppel certificate?

Find out why first. Often there is a dispute, a wrong number or a form the lease does not require, and fixing the cause is faster than enforcing. A deemed-certification, attorney-in-fact or default remedy in the lease may apply, but confirm early whether the buyer or lender will accept anything other than a signed certificate.

Can a tenant change the estoppel certificate form?

A tenant can correct facts and, where the lease allows, limit statements to its knowledge. Whether it must sign extra lender items depends on the lease: if the lease attaches a form or limits the content, the tenant generally does not have to confirm more. Treat each edit as a variance, check it against the documents, and clear it with the buyer or lender.

Does a tenant have to sign an SNDA?

It depends on the lease. Many leases require the tenant to sign subordination documents on request, sometimes only if the lender grants non-disturbance, and sometimes only in a commercially reasonable form. Where the lease is silent, signing is a negotiation. Tenants generally want non-disturbance, so the real discussion is usually the lender’s limits on successor-landlord liability.

How recent does an estoppel certificate need to be at closing?

The purchase contract or loan commitment usually limits how old a certificate can be when the deal closes. Track the date each certificate is signed, not just the date it arrives. If closing slips past that limit, expect a request for new certificates or short bring-down confirmations, which means another round of tenant cooperation.

Do federal tenants sign estoppel certificates?

Under a GSA lease, the government commits to a narrower Statement of Lease rather than a commercial estoppel. The contracting officer’s letter, based on the lease file, states whether the lease is in full force, the date to which rent has been paid in advance, and whether a notice of default has been issued. Plan diligence around that letter.
