Tenant Estoppel Certificate: A signed statement from a tenant confirming—or contradicting—the key terms of their lease. The estoppel is the "truth serum" of commercial real estate. Whatever the tenant writes on this form overrides your rent roll, your lease, and your word.
Why Do Lenders Care What Tenants Think?
You submitted a clean T-12. Your leases match your rent roll. Your documentation is tight. Why is the lender asking your tenants to verify what you already provided?
Because tenants know things that don't appear in your documents. The handshake deal. The verbal rent reduction. The promised free month. The dispute about CAM charges. The estoppel forces these hidden agreements into the light—before the lender closes.
What Is the Hierarchy of Truth?
When documents conflict, lenders use a clear hierarchy:
| Document | Authority Level | Why |
|---|---|---|
| Tenant Estoppel | Absolute | Signed by the tenant, dated, legally binding |
| Executed Lease | Strong | Signed by both parties, but may have amendments |
| Rent Roll | Weak | Created by landlord, no tenant verification |
The Override Rule: If your rent roll shows $2,000/month, your lease shows $2,000/month, but the tenant writes "$1,800—owner gave me a discount after the roof leak," the lender underwrites to $1,800. The estoppel wins. Every time.
When Are Estoppels Required?
Guide Section 55SBL requires tenant estoppels for:
| Commercial Tenants | Required for all commercial tenants contributing >5% of gross income |
| Residential Tenants | Rarely required (too many tenants, too much friction) |
| Mixed-Use Properties | Required for ground-floor retail/commercial spaces |
| Section 8 Tenants | HAP contract serves as de facto estoppel |
The Commercial Trap: Residential multifamily borrowers often forget they have commercial exposure. That ground-floor laundromat? The cell tower on your roof? The property manager's office? If it's a commercial lease contributing meaningful income, expect an estoppel requirement.
What Does an Estoppel Ask?
A standard estoppel certificate requires the tenant to confirm:
Standard Estoppel Contents
- Lease Identification: Property address, unit number, lease date
- Rent Amount: Current monthly rent (base + CAM + taxes)
- Lease Term: Commencement date, expiration date, renewal options
- Security Deposit: Amount held by landlord
- Prepaid Rent: Any rent paid in advance
- Amendments: Any modifications to the original lease
- Defaults: Is the landlord in default of any obligations?
- Side Agreements: Any verbal promises or unwritten modifications
What Are the Deal Killers?
These tenant disclosures on estoppels trigger immediate lender scrutiny:
| Disclosure | What It Means | Loan Impact |
|---|---|---|
| "Rent is different than stated" | Verbal modification to lease terms | Underwrite to lower rent; lost proceeds |
| "Landlord owes me a rent credit" | Promised concession not yet applied | Deduct credit from income |
| "I have a verbal renewal option" | Tenant claims extension rights not in lease | Affects lease expiration analysis |
| "Landlord hasn't made required repairs" | Landlord potentially in default | Legal review; potential repair escrow |
| "My security deposit is different" | Records don't match | Reconciliation required |
| "I have a purchase option" | Tenant can buy the property | Major title issue; may kill deal |
The "Verbal Mod" Nightmare: "My landlord said I could pay $200 less next year because I referred a new tenant." If the tenant writes this on the estoppel, the lender deducts $2,400 annually from your income. That's $31,000+ less in loan proceeds—for a handshake deal you may have forgotten.
What Is an SNDA and Why Does It Matter?
The estoppel often comes with an SNDA—Subordination, Non-Disturbance, and Attornment Agreement. This three-part agreement protects all parties:
| Component | What It Means | Who It Protects |
|---|---|---|
| Subordination | Tenant's lease is junior to the mortgage | Lender—can foreclose without tenant blocking |
| Non-Disturbance | Lender won't evict tenant in foreclosure | Tenant—can stay if they're paying rent |
| Attornment | Tenant agrees to pay rent to new owner (bank) | Lender—income continues post-foreclosure |
Why Attornment Matters: The lender needs to know that if they foreclose, your tenants will pay rent to the bank—not just stop paying because the ownership changed. The SNDA locks this commitment in writing.
How Do I Prevent Estoppel Problems?
Before You List the Property
Pre-Sale Estoppel Prep
- Audit All Verbal Agreements: Write down every promise you've made to tenants
- Formalize Side Deals: Turn verbal modifications into written lease amendments
- Check Security Deposits: Verify your records match what tenants think they paid
- Resolve Disputes: Fix any landlord defaults before the estoppel airs your laundry
- Pre-Fill the Form: Give tenants a pre-populated estoppel; they only need to confirm or correct
During the Transaction
| Start Early | Request estoppels 3-4 weeks before closing, not 3 days |
| Use the Lender's Form | Don't create your own; use the lender's approved template |
| Follow Up Aggressively | Commercial tenants need corporate approval—this takes time |
| Offer Incentives | A $50 gift card speeds things up; it's worth the closing certainty |
| Get Them Notarized | Some lenders require notarization; ask upfront |
The Timeline Killer: You can't close until commercial estoppels are signed. If your anchor tenant's corporate office takes 2 weeks to return a signed form, your closing moves 2 weeks. If that pushes you past rate lock expiration, you're re-locking at whatever rates exist that day.
What If a Tenant Refuses to Sign?
Tenants have no legal obligation to sign an estoppel—unless their lease requires it (most commercial leases do). If a tenant refuses:
| Approach | When to Use |
|---|---|
| Review the Lease | Most commercial leases require cooperation on estoppels |
| Explain the Stakes | Tenant may not realize refusal could block a sale |
| Offer Something | Minor concession (parking, signage) in exchange for signature |
| Landlord's Estoppel | Some lenders accept a landlord-signed estoppel with lease attached (last resort) |
The Lease Clause Fix: For future leases, include an estoppel cooperation clause: "Tenant agrees to execute an estoppel certificate within 10 business days of landlord's written request." This gives you contractual leverage.
What's on the Estoppel Checklist?
Pre-Closing Estoppel Verification
- All Commercial Estoppels Collected: Every tenant >5% of income
- No Contradictions: Estoppel terms match rent roll and leases
- No Disclosed Modifications: No verbal side deals revealed
- Security Deposits Match: Tenant's stated deposit = your records
- No Landlord Defaults Claimed: Tenant hasn't flagged unresolved issues
- SNDAs Executed: If required, tenant has signed subordination agreement
- Properly Dated and Signed: Within 30 days of closing
The Bottom Line: The estoppel is where verbal promises come to die—or kill your deal. Know what your tenants think before they put it in writing. Formalize every side agreement. Start collection early. The estoppel isn't a formality—it's the last chance for hidden landmines to surface.
