Lease Subordination and Attornment Clause

A lease subordination and attornment clause (SNDA) defines what happens to a lease if the property is mortgaged, refinanced, or foreclosed. It specifies whether the lender’s mortgage is senior to (takes priority over) the lease, and requires the tenant to accept a new landlord if the property changes hands through foreclosure or sale.

The lender’s perspective and subordination

When a landlord borrows money using the property as collateral, the lender (a bank or institutional investor) takes a mortgage. The mortgage creates a security interest: if the landlord defaults, the lender can foreclose and take ownership. But the lender needs assurance that taking ownership will be clean and valuable. If a long-term lease exists and is senior to the mortgage, the lender’s collateral is constrained—a new owner inherits the tenant and cannot immediately evict or renegotiate.

To solve this problem, lenders require subordination. The lease is made subordinate to the mortgage, meaning the mortgage takes priority. If the landlord defaults and the lender forecloses, the lender (or a buyer at the foreclosure sale) can step in and—in theory—cancel the lease or renegotiate it on fresh terms. Subordination makes the lender’s collateral more flexible and valuable.

Attornment: accepting a new landlord

Attornment is the tenant’s legal obligation to recognize a new landlord post-foreclosure and continue paying rent to that party. Without an attornment clause, a foreclosed tenant might argue it owes nothing to the new owner (since there is no contract between them) or that the foreclosure severed the lease entirely.

Attornment clauses ensure continuity. If the property is foreclosed and sold to a buyer or taken by the lender, the tenant must immediately recognize the new owner as landlord and resume rent payments. The tenant cannot use the foreclosure as an excuse to stop paying, hold rent in escrow, or abandon the property.

The subordination-attornment tradeoff

A pure subordination-only clause exposes the tenant to significant risk. If the landlord defaults on the mortgage and the lender forecloses, the lender can wipe out the tenant’s lease, especially if the lease is unprofitable to the lender or the tenant is a month-to-month occupant. A high-rent market, a distressed lender, or a foreclosure sale can all result in lease termination. The tenant loses the property and any renewal options or favorable rent terms negotiated in the original lease.

Tenants prefer non-subordination, where the lease is senior to any mortgage. But this makes the property less attractive to lenders, harder to refinance, and riskier to borrow against. A commercial landlord refinancing a $10 million property with a major retailer will find that the lender insists on subordination, forcing the tenant to choose between accepting the risk or losing the property.

The SNDA: subordination with protections

Most commercial leases use an SNDA—a subordination, non-disturbance, and attornment agreement. The acronym captures the structure:

• Subordination: The lease is junior to the lender’s mortgage.
• Non-disturbance: If the loan is in good standing (landlord is current), the lender agrees not to disturb the tenant’s right to occupy and enjoy the space.
• Attornment: The tenant agrees to recognize a new owner if foreclosure occurs.

An SNDA is a three-party agreement signed by the landlord, the tenant, and the lender. The lender makes a binding promise that as long as the tenant pays rent and performs the lease, the tenant will not be evicted even if the lender forecloses. This protects the tenant’s occupancy during the loan term. But if the landlord defaults and the lender forecloses, the tenant must accept a new landlord and remain bound by the original lease terms.

When SNDAs protect tenants

SNDAs are most protective when they include explicit carve-outs or protections:

• Lender subordination caps: The lender waives its right to subordinate future mortgages or refinancings beyond a specified amount.
• Rent abatement caps: If the property is damaged or partially destroyed, the tenant’s rent abates only up to a set percentage; beyond that, the tenant can terminate.
• Default definitions: The lease must be in breach for a material period (e.g., 60 days) for the lender to enforce; minor delays do not trigger foreclosure risk.
• Notice to tenant: The lender must notify the tenant of a default and give the tenant an opportunity to cure, protecting the tenant from surprise eviction.
• Estoppel letters: The tenant provides periodic letters confirming no defaults and that rent is current, protecting the lender’s title.

Large, creditworthy tenants (e.g., publicly traded retailers) often negotiate SNDAs that are heavily tenant-favorable. Smaller tenants may accept a plain SNDA with minimal protections.

Practical impact: foreclosure scenarios

Scenario A: A retail tenant has a 10-year lease at $50/sq ft in a prime location. The landlord defaults, and the property is worth less than the mortgage balance (underwater). The lender forecloses. Because the lease is subordinate, the new lender-owner can terminate the lease or demand new terms. The tenant loses the lease and must vacate or renegotiate, likely at higher rent in a now-tighter market.

Scenario B: The same tenant negotiates an SNDA with a strong non-disturbance clause. The lender forecloses, but the SNDA protects the tenant’s occupancy and rent terms. A new owner takes over, and the tenant remains at the original $50/sq ft. The tenant continues undisturbed.

Scenario C: The tenant is month-to-month with subordination. The lender forecloses and immediately terminates the lease, evicting the tenant without a long-term lease claim. The tenant loses all occupancy rights.

Subordination and lease value

Subordination directly affects lease economics. A landlord with a $10 million mortgage subordinating a $2 million annual revenue lease is making a statement: the tenant’s lease is worth less than the debt. If the property crashes in value, the lender has priority, and the tenant can be evicted.

This affects tenant negotiating power. A tenant in a subordinate lease has less security and may demand lower rent, renewal options, or buyout rights to offset the risk. A non-subordinate or protected lease can command premium economics because the tenant’s security is higher.

Renegotiation during refinancing

When a landlord refinances, the new lender typically requires a fresh SNDA. The tenant may have to re-sign, and the new lender might impose stricter terms. A tenant that originally negotiated tenant-friendly language might lose it during a refinance if the market has changed or the new lender is more aggressive. Tenants should anticipate that subordination and attornment can shift through the lease term.

Subordination and ownership changes

Subordination also applies to non-mortgage ownership transfers. If the landlord sells the property to a buyer who assumes the existing mortgage, subordination ensures the buyer (new landlord) has priority over the tenant’s lease rights. The tenant remains bound but is now answerable to a different entity. Attornment clauses make this transition smooth.
