Your landlord signed your blend-and-extend. If its lender didn't, the rent cut can unwind.

On a 150,000 SF building in Ontario, a blend-and-extend that resets rent from $1.45 to $1.05/SF/mo NNN saves you $720,000 in the first year. If your landlord's lender never consented to that amendment in writing, and the loan fails before your original October 2029 expiry, the lender or whoever buys from it can treat the rent cut as never made. That puts back $0.40/SF/mo, $4.80/SF/yr, and $2,247,552 through 2029: $14.98/SF, or 14.3 months of your new rent.

The consent requirement is not in your lease or in the amendment. It sits in the subordination, non-disturbance and attornment agreement (SNDA) you signed at the original lease or at a later refinance, and lender forms commonly say a successor owner is not bound by any amendment made without the lender's written consent. Nothing in a standard amendment form asks who holds the loan.

California starts from a hard rule. Foreclosure of a senior deed of trust terminates a junior lease (Principal Mut. Life Ins. Co. v. Vars, Pave, McCord & Freedman (1998) 65 Cal.App.4th 1469; Dover Mobile Estates v. Fiber Form Products (1990) 220 Cal.App.3d 1494). A lease subordinated to the loan survives foreclosure only through the SNDA's non-disturbance and attornment terms. In the AIR single-tenant net lease the subordination sits at ¶30, Subordination; Attornment; Non-Disturbance. The term that strips your amendment does not come from the AIR form. It comes from the lender's SNDA.

A KeyBank SNDA filed with the SEC says the lender is not “bound by any amendment, modification, or waiver of any of the provisions of the Lease” unless it was “taken with the prior written consent of Lender,” and separately commits the tenant: “Tenant shall enter into no material amendment or modification of the Lease without Lender's prior written consent.” A Regions Bank form says the same of amendments made without the lender's written consent. Smith Gambrell & Russell calls forgetting the SNDA exists a common mistake, and notes that a rent concession granted for an extension may not bind a successor after foreclosure.

The landlord's loan documents point the same way. Typical covenants bar the borrower from entering into a “renewal, extension or modification” of a Major Lease without lender approval. Holland & Knight's June 2026 review puts “changes that reduce rent” squarely inside the lender's consent right, and a loan-documents guide in Law Journal Newsletters lists rent reductions among the exceptions to deemed-approval provisions. Lowndes puts the lender's view plainly: “The Lender does not want the Tenant to amend the Lease without its approval while the Lender's loan is outstanding.” A rent cut lowers NOI and debt coverage, so it is the modification a lender is least likely to approve. That gives a landlord under pressure a reason not to ask.

The odds are low and the loss is large. Industrial CMBS loans were 1.14% delinquent in September against 8.02% for all CMBS, per Trepp, and 2.35% in distress per CRED iQ. We found no named IE industrial loan in special servicing or foreclosure this year. The selection runs against you, though. IE starting rent fell 24.4% from its Q2 2023 peak of $17.64/SF/yr to $13.33 by Q2 2026, per CompStak. Lee & Associates' Q2 2026 IE West report found tenants “remained in a favorable position with greater leasing options and increased flexibility during negotiations.” The landlords who agree to the deepest cuts are the ones under the most pressure, and those are the buildings most likely to change hands through the lender.

The SNDA protects your occupancy. It does not protect your amendment. The successor chooses whether the amendment binds it. You do not. Whether it can keep your five added years while rejecting the rent cut turns on your SNDA's wording, and we found no published California case on it. The same carve-outs reach the rest of a typical blend-and-extend. KeyBank's form does not bind a successor to rent paid “more than one month in advance,” Regions Bank's to “offsets, claims, credits or defenses,” and lender forms Sherin and Lodgen reviewed free the new owner from “completing any construction of improvements.” Abatement months you have not taken and TI allowance not yet funded are the first things to go.

Not every SNDA carries the carve-out. Some exempt non-material amendments or give deemed consent, and some buildings carry no loan at all. A lease with no SNDA is worse off, not better: under the California rule, foreclosure ends it. Check your recorded SNDA.
