Commercial mortgage delinquencies rose to 4.02% in the first quarter of 2026, up from 3.86% the quarter before, and CMBS loans specifically are running at 5.21% delinquent, the highest of any capital source the Mortgage Bankers Association tracks. Office, lodging, retail, and multifamily loans all got worse; industrial was the only property type that improved.[1] Separately, $76.6 billion in CMBS loans face hard maturities in 2026 out of a $146.2 billion maturity calendar, and roughly $27.3 billion of that carries a debt yield of 8% or less, the range where refinancing usually fails and the loan heads toward workout or foreclosure instead.[2] None of that shows up in a tenant’s rent statement. It shows up, if it shows up at all, as a letter announcing a new landlord.
Every commercial lease has a clause that decides what a tenant’s occupancy is worth on that day, and most tenants have never read it closely enough to know which side of it they’re on.
Subordination is automatic. Non-disturbance has to be signed, and most tenants never check whether it was.
The lease already agreed to come second. Standard lease language subordinates the tenant’s leasehold interest to any mortgage the landlord has now or takes out later — meaning if the lender forecloses, the lender’s claim on the building outranks the tenant’s claim on the space.[3] That clause is boilerplate. It’s in the lease whether or not a tenant negotiated it, because almost nobody does.
The matching protection is not boilerplate; it’s a separate document, and it usually isn’t offered. A non-disturbance agreement is the lender’s promise that a paying, non-defaulting tenant gets to stay after foreclosure. It doesn’t exist by default. It exists when a tenant, landlord, and lender all sign a three-party SNDA, and in most deals that document only surfaces when the landlord’s lender requires one as a closing condition on the landlord’s own financing — not at lease signing, and not because the tenant asked.[4] Residential tenants have statutory backstops in some situations. Commercial tenants generally don’t; the SNDA is the whole protection, and if it never gets signed, a foreclosure can end the lease outright.[5]
Even a signed SNDA usually protects your right to stay, not the money you already spent. Many SNDA forms specifically exclude monetary obligations from carrying over to the successor landlord — unpaid tenant improvement reimbursements, rent credits, prior landlord defaults. A tenant that fronted a build-out expecting the landlord to pay it back can keep the space after foreclosure and still lose the reimbursement, because the new landlord picked up the lease, not the old landlord’s debts.[3]
Why the timing works against the tenant almost every time. The moment a tenant has the most leverage to negotiate SNDA terms is before the lease is signed, when the landlord wants the deal closed and can lean on its own lender to move fast. Once the lease is signed, the tenant is waiting on someone else’s financing timeline — the SNDA shows up, if it shows up, whenever the landlord happens to refinance, and by then the ask is usually “sign this” rather than “let’s negotiate this."[4] A tenant who never raised it at signing is negotiating from a document a lender’s counsel already wrote, on a schedule set by someone else’s refinancing, not the tenant’s lease.
That timing gap gets worse in exactly the market this year’s numbers describe: more loans maturing at yields too low to refinance cleanly, which means more of them get extended, restructured, or handed to a special servicer — the same maturity wall that’s already forcing lenders to renegotiate what “non-recourse” actually covers once a loan goes into extension. A tenant sitting under one of those loans doesn’t get a vote in whether it refinances. It only gets a vote in whether its own lease already has the paperwork that survives the outcome.
Knowing which leases in a portfolio would actually survive a foreclosure#
Finding out does our lease have a signed SNDA, and does it cover the improvement allowance we’re still owed usually means pulling the transfer-and-assignment or financing article out of a specific lease and reading it against whatever side letters exist, one property at a time. Across a portfolio of fifty leases sitting under fifty different landlords’ mortgages, that’s not a question anyone can answer from memory. Acrebase parses leases into structured data, flags whether an SNDA was executed and what it does and doesn’t cover, and lets a team query an entire portfolio in plain language — which leases have signed protection, which don’t, and which have a gap between subordination and non-disturbance that nobody closed — with every answer traced back to the source clause.
Acrebase also applies a firm’s approved clause library and negotiation playbook automatically, so a tenant’s standard ask — SNDA delivered as a condition of lease execution, monetary obligations carried over, cure rights preserved — gets proposed the same way on every deal, instead of depending on which associate remembered to raise it. Its AI, trained on prior negotiations, can flag when an incoming SNDA draft is narrower than what the firm has gotten elsewhere, before it gets signed.
The practical takeaway: if you’re a tenant, ask for the SNDA before you sign the lease, not after, and read whether it protects money owed to you or just your right to occupy the space. If you’re a landlord, get ahead of your lender’s closing conditions now rather than during a refinance under pressure — a tenant who’s asked twice and been ignored twice is the tenant most likely to slow down your next deal.

[3] Adventures in CRE, “Subordination, Non-Disturbance, and Attornment Agreement” — many SNDAs limit or prohibit a landlord’s monetary obligations, including unreimbursed tenant improvement costs, from transferring to a successor landlord; SNDA terms are best negotiated before lease execution, while the landlord still has incentive to close the deal. https://www.adventuresincre.com/subordination-non-disturbance-attornment-agreement/
[4] McLane Middleton, “Know the Law: Subordination, Non-Disturbance and Attornment Agreements” — SNDAs are typically required by a commercial lender as a closing condition on the landlord’s own financing, rather than negotiated at lease signing; without an SNDA, foreclosure of the leased property can result in the tenant being evicted; commercial tenants have fewer statutory safeguards than residential tenants in this situation. https://www.mclane.com/insights/know-the-law-subordination-non-disturbance-and-attornment-agreements/
