Subordination, non-disturbance, and attornment agreements sit quietly in lease files until a lender calls them front and center. When a building is refinanced, the SNDA moves from background document to live negotiation, and the gaps that looked minor at lease execution suddenly carry real financial and operational weight. Understanding the 6 SNDA issues that surface when a building is refinanced gives advisers, tenants, and owners a sharper lens for deal-execution before the lender's counsel sets the timeline.
Why Refinancing Triggers SNDA Review
A refinancing event restructures the security position of the debt secured by the property. The incoming lender acquires a new mortgage lien, and that lender's counsel will review every existing lease to confirm that tenant rights do not impair the collateral position. SNDAs are the mechanism that balances tenant protection against lender security, so their terms become operative the moment a new loan closes.
Many SNDAs executed during the original lease term were negotiated against the requirements of a prior lender. That prior lender's form may have included concessions the new lender will not accept. The refinancing process therefore frequently requires SNDAs to be renegotiated, amended, or restated — a process that can take weeks and sometimes stalls a loan closing.
The practical consequence for tenants is that lenders routinely require SNDA estoppels to confirm that no landlord defaults exist and that lease terms are as represented in the rent roll. For advisers working alongside occupier clients, the refinancing window is one of the few moments in a tenancy when the tenant holds real negotiating leverage. That leverage disappears once the loan closes and the SNDA is confirmed.
Issue 1 — The Subordination Clause Reorders Priority Without a Guard Rail
Subordination makes the tenant's leasehold interest junior to the lender's mortgage lien. This is the starting position most institutional lenders require, and most commercial leases contain an automatic subordination clause. The danger is an automatic subordination with no corresponding non-disturbance protection. If the mortgage is foreclosed and the SNDA does not bind the successor to honor the lease, the tenant can be displaced regardless of remaining term.
When a building is refinanced, the new lender's counsel will examine whether the existing SNDA's subordination language is self-executing or requires a separate instrument. Some older SNDA forms require both parties to sign a separate subordination agreement before the mortgage closes. If that signature was never obtained, the existing SNDA may be unenforceable against the new lender as written, creating a gap in protection.
Advisers reviewing SNDAs for occupier clients should confirm that the subordination and the non-disturbance are genuinely paired — that accepting junior status is conditional on the lender's commitment to honor the lease in a foreclosure scenario. A subordination clause that stands alone is a one-sided concession. The tenant's lease analysis should flag this pairing as a threshold condition before any refinancing SNDA amendment is signed.
Issue 2 — Non-Disturbance Carve-Outs That Eliminate the Core Protection
Non-disturbance is the tenant's side of the bargain: the lender agrees that if foreclosure occurs, the tenant's right to occupy will continue as long as the tenant is not in default. The problem is that lenders routinely negotiate carve-outs that substantially reduce what non-disturbance actually covers. Understanding which carve-outs are standard and which are overreaching is where lease analysis software and experienced counsel earn their value.
Standard carve-outs include tenants in monetary default, tenants holding lease modifications that were not approved by the lender, and tenants in possession under subleases not consented to by the lender. Each of these is commercially reasonable. What is not reasonable — but appears in lender forms — is a carve-out that excuses the lender from honoring any lease concession, rent abatement, or landlord obligation that was not disclosed in the lender's loan underwriting file.
This particular carve-out can strip away free rent periods, tenant improvement allowance repayment rights, and landlord build-out obligations that have not yet been completed. If a lease was signed eighteen months before the refinancing and the landlord still owes a substantial TI reimbursement, that obligation can effectively disappear if the SNDA's non-disturbance language is not drafted to survive foreclosure. Advisers must audit lease economics against SNDA non-disturbance scope before the refinancing closes.
Issue 3 — Attornment Language That Contradicts the Original Lease
Attornment requires the tenant to recognize a successor landlord — typically the lender or a purchaser at a foreclosure sale — as the new landlord under the existing lease terms. Most attorneys treat attornment as a formality, but its precise language can materially alter the tenant's obligations. Specifically, the moment a successor landlord is defined as holding a lien rather than a fee interest, the tenant may be paying rent to a party who cannot legally grant renewals, extensions, or consents.
When a building is refinanced, the new lender's SNDA form will usually include an attornment clause that limits successor landlord liability for acts or omissions of prior landlords. This is the lender's reasonable protection — it did not create the prior landlord's defaults and should not inherit them. The issue surfaces when the limitation is drafted so broadly that the successor is relieved of obligations the prior landlord affirmatively undertook in the lease, including completion of landlord work, reimbursement of approved tenant costs, and delivery of quiet enjoyment.
Tenants negotiating an SNDA amendment during a refinancing should push for an explicit acknowledgment that the successor landlord assumes the economic obligations that were part of the lease at the time the SNDA was entered into. The concept of a "snapshot" of landlord obligations as of the SNDA date gives both parties a defined baseline. Without that snapshot, the attornment clause becomes a mechanism for reducing the lease to its minimum economic terms at the moment of foreclosure.
Issue 4 — Lender Consent Requirements That Were Never Satisfied
Commercial leases frequently require lender consent for lease modifications, subleases, assignments, and certain landlord waivers. This is standard. The problem that surfaces at refinancing is that many of those consent requirements were simply never satisfied during the lease term. The landlord and tenant agreed to a lease amendment, changed the permitted use, or allowed a subtenant into the space — and no one obtained the lender's consent because the original SNDA's consent requirements were not front of mind.
When the new lender conducts due diligence, it will review the rent roll, the existing leases, and any recorded lease amendments. If a lease amendment was recorded without the prior lender's consent, the new lender will flag it as an unauthorized modification. The practical consequence is that the new lender may treat the modified lease terms as unenforceable against its security interest, reverting to the original lease form for underwriting purposes.
Advisers supporting a landlord client through a refinancing should run a consent audit before lender due diligence begins. This means pulling every lease amendment, every sublease consent, and every landlord waiver and confirming that corresponding lender consents exist in the file. Where they do not, the landlord may need to obtain a lender confirmation of ratification before the refinancing closes. Missing consents discovered late in a loan process have derailed closings.
Issue 5 — Lease Termination Rights That Threaten Lender Collateral
Many commercial leases give tenants the right to terminate the lease on the occurrence of specified events: a casualty the landlord does not restore within a defined period, a condemnation that takes a threshold percentage of the premises, a failure of the landlord to deliver vacant possession by a long-stop date, or a co-tenancy failure in a retail context. These termination rights protect tenants from being locked into unusable space. They also reduce the value of the lender's collateral if exercised.
When a building is refinanced, the incoming lender will analyze every lease termination right as a contingent liability against the rent roll. If a major tenant holds a termination right that could eliminate thirty percent of the building's income, that risk will affect the loan-to-value underwriting. The lender may require the tenant to waive the termination right, limit its exercise conditions, or confirm in an SNDA amendment that the right is not currently triggered.
The challenge for the tenant is that waiving or limiting a termination right is a real economic concession. The tenant negotiated that right because it valued the optionality. Advisers should evaluate whether the landlord is offering any consideration in exchange for a termination right modification — a rent concession, an extension option, an improvement allowance. Conceding a termination right without compensation is a loss of value that the tenant's lease analysis should quantify before any SNDA amendment is signed.
Deal-execution discipline requires that tenant-side advisers document the economic value of any termination right before engaging with lender requests. This is not an abstract exercise. Calculating the lease net present value with and without the termination right, using realistic probability weights on the trigger conditions, gives the tenant's negotiating team a defensible number to work from.
Issue 6 — Estoppel Conflicts That Surface During Lender Due Diligence
The SNDA process at refinancing almost always includes an estoppel certificate request. The estoppel asks the tenant to confirm the lease commencement date, rent amounts, security deposit held, absence of landlord defaults, and accuracy of the rent roll. The estoppel is then delivered to the new lender as a representation on which the lender relies in closing the loan. Estoppel conflicts — where the tenant's representations differ from the landlord's rent roll — are among the most common obstacles in a refinancing.
Estoppel conflicts arise when the lease has been verbally modified, when side letters exist that were not disclosed to the lender, or when the rent roll does not reflect actual rents being paid due to informal rent deferrals or abatements agreed outside the written lease. Any of these discrepancies puts both the landlord and the tenant in a difficult position. The tenant who signs an estoppel that contradicts a prior verbal agreement may be waiving that agreement. The tenant who refuses to sign or qualifies the estoppel may trigger a loan default notice.
The right approach is a pre-refinancing estoppel reconciliation. The landlord and tenant should compare their respective understandings of the lease economics before the lender's estoppel certificate is circulated. Where discrepancies exist, they should be resolved by a written lease amendment that reflects the agreed terms. This eliminates the ambiguity before the lender's timeline creates pressure to sign a qualified or inaccurate estoppel. Advisers should build this reconciliation step into every refinancing checklist.
A further complication is that lenders often circulate non-negotiable estoppel forms that ask the tenant to make representations the lease does not require. Tenants can legitimately push back on representations that go beyond the lease's estoppel clause.
How Advisers Should Structure the SNDA Review Process
The six issues above do not appear in isolation. A building refinancing typically triggers several of them simultaneously, and lender counsel will be working on a compressed timeline. The adviser who has organized the client's lease file, flagged the operative SNDA provisions, and prepared a summary of tenant rights before lender due diligence begins will consistently secure better outcomes than the adviser reacting to lender requests in real time.
The review process should start with a lease abstraction that extracts every SNDA-related provision: subordination, non-disturbance conditions and carve-outs, attornment successor landlord limitations, termination rights with their trigger conditions, estoppel certificate requirements, and lender consent triggers. That abstraction becomes the working document for the SNDA negotiation.
Timing matters as much as substance. Lenders will typically require SNDA confirmation thirty to sixty days before loan closing. Tenant-side advisers who engage at day one of that window, rather than day twenty, have room to negotiate meaningful non-disturbance protections and estoppel reconciliations. Advisers who engage late are trading off substance for speed.
Pricing the Risk Inside the SNDA Negotiation
Every SNDA issue carries a financial value that should be modeled before the negotiation begins. A non-disturbance carve-out that eliminates a landlord's TI obligation has a dollar value equal to the outstanding obligation. A termination right waiver has a value equal to the probability-weighted NPV of the option to exit the lease. A missing lender consent has a remediation cost equal to the legal fees required to obtain a ratification and potentially the value of the lease provision that the lender treats as unenforceable.
Advisers should build these valuations explicitly rather than leaving them implicit in a legal negotiation. When an SNDA amendment is proposed, the economic impact on the lease NPV can be quantified and used to determine whether a concession requires offsetting consideration.
Building a Critical-Date Calendar Around the SNDA
SNDA-related deadlines are some of the most consequential in commercial real estate. A tenant who misses an estoppel response deadline may inadvertently confirm facts it disputes. A landlord who misses a lender consent deadline may lose the right to modify the lease without lender approval. An adviser who does not track these deadlines systematically will eventually miss one, with real consequences for the client.
The practical solution is a critical-date calendar built from the lease and SNDA provisions, with named owners for each deadline and escalation procedures when deadlines approach without resolution. This is not a spreadsheet exercise — it is an operational discipline. The dates must be tied to the responsible party, the consequence of missing the date, and the action required to avoid that consequence.
Refinancing timelines are imposed by lenders, not by the parties. The lender's rate lock expiration, its commitment letter deadline, and its closing date create a fixed external frame. Every SNDA action — estoppel delivery, SNDA amendment signature, lender consent confirmation — must be mapped against that frame. Advisers who build that mapping at the outset avoid the compressed, error-prone negotiations that happen when SNDA issues land on the closing table.
What Tenants Often Overlook in the Final SNDA Form
The most common mistake tenants make at refinancing is treating the SNDA as a landlord document that requires a signature rather than a tenant-negotiated instrument that shapes their occupancy rights for the life of the loan. Many tenants sign the lender's form with minimal review because the refinancing feels like the landlord's transaction. It is not. The SNDA binds the tenant to the new lender's terms and determines what rights survive a foreclosure.
Tenants should request the new lender's proposed SNDA form at least thirty days before the required signature date. They should send it to their own counsel for review, not rely on the landlord's representation that it is a standard form. Standard lender forms favor the lender — that is what they are designed to do, and there is nothing improper about a tenant insisting on modifications that protect its occupancy rights.
The SNDA review should address every issue catalogued here: the scope of non-disturbance carve-outs, the successor landlord liability limitations in the attornment clause, the treatment of outstanding landlord obligations, the estoppel representations required, and any termination right modifications the lender is requesting. Advisers who bring this structure to the SNDA review will identify the issues that matter most to the tenant's economics and prioritize them in negotiation, rather than treating every lender comment as equally important.
That confirmation is not a formality; it is the starting point for identifying where the lender's form departs from the existing framework.
Preparing the Client Brief Before the Lender Engages
The adviser's most valuable contribution to a refinancing SNDA process is the work done before the lender's counsel circulates its first request. That work starts with a complete review of the existing lease file: the lease, all amendments, the existing SNDA if any, all estoppel certificates previously delivered, and all correspondence with the landlord or prior lender about SNDA-related matters. Any gaps in that file are gaps in the tenant's negotiating position.
The alternative — reassembling scattered files under lender-imposed deadline pressure — is both costly and error-prone.
