Negotiating a CMBS loan assumption

Identify approval standards, transaction timing, and continuing borrower obligations.

An assumption can preserve an existing loan while transferring ownership of the financed property. For a multifamily seller, it may support a buyer's economics without requiring the seller to fund a costly debt exit. For the buyer, it can supply an attractive existing financing package. The transaction still needs to satisfy transfer provisions, credit requirements and the applicable servicing process.

Separate three questions at the outset: whether the transfer is permitted, what terms the buyer accepts and which seller obligations are released. A favorable coupon does not answer any of them. The tax definition of an assumption expressly includes situations where the buyer becomes liable and the seller remains liable, as well as situations where the lender releases the seller.[1]

Classify the proposed ownership change

Describe the transaction precisely. A deed transfer, sale of the property borrower's interests, transfer of an upstream ownership entity and introduction of a new control party can have different consequences under the documents. Draw the existing and proposed organizational charts with percentages, control rights and proposed guarantors.

The ICNQ 2024-MF servicing agreement addresses due-on-sale provisions that can include direct or indirect ownership transfers and pledges.[2] It illustrates why a borrower should not focus solely on whether title to the real estate changes. The agreement's conditions govern that securitization; another loan may define permitted transfers differently.

A February 2025 mortgage-loan purchase agreement contains seller representations addressing due-on-sale restrictions and specified exceptions.[3] These representations are evidence of the issues addressed in particular loans, not a source of permission for a reader's transaction. The original borrower's own executed documents must identify the permitted route.

Ask counsel to distinguish a transfer allowed after notice from one requiring consent and one needing an assumption or modification agreement. Prepare the request for the actual transaction rather than proposing an abstract change in ownership. If the buyer's capital structure includes junior debt or preferred equity, disclose the related rights and entity changes together.

Confirm who can approve the request

The servicer handling routine monthly payments may coordinate an assumption without possessing sole authority to approve it. In the ICNQ agreement, §3.09 allocates assumption functions between master and special servicers and conditions certain actions on credit criteria and no-downgrade requirements.[2] The applicable process can also involve companion interests.

Request a written list of information, approvals and fees needed for the proposed transaction. Assign responsibility for buyer financial statements, property reports, organizational documents, guarantor information and counsel deliverables. Ask which review starts only after the package is complete and which reviews can proceed in parallel.

The ICNQ agreement contains a specific deemed-consent mechanism measured after receipt of the master servicer's analysis and reasonably required information.[2] It does not establish a guaranteed end-to-end assumption timetable. A seller should not convert an internal response provision into a closing promise to a buyer.

Compare the buyer's funding and carrying costs

Consider a hypothetical property priced at $160 million. The existing loan has a $100 million balance, a 4.50 percent interest-only coupon and four years remaining. Assume it can be assumed on those terms. The buyer budgets $2 million of transaction costs, $900,000 of assumption expenses and $2 million of required reserves.

The buyer's initial equity requirement is $160 million plus $2 million plus $900,000 plus $2 million, less $100 million of assumed debt: $64.9 million. Assume instead a new $95 million interest-only loan at 6.50 percent, with $1.2 million of financing costs and $1 million of reserves. With the same purchase price and transaction costs, the equity requirement is $69.2 million.

The assumed loan therefore requires $4.3 million less initial equity under these invented inputs. Annual interest is $4.5 million on the assumed loan and $6.175 million on the new loan, a $1.675 million difference. Over four unchanged years, the nominal interest difference is $6.7 million, before time value, taxes or other expenses.

Those figures do not imply the seller can increase the purchase price by $6.7 million. The buyer still needs to evaluate the larger $100 million balloon, the remaining maturity, cash restrictions and refinancing risk. If the assumption requires additional reserves, a principal paydown or altered terms, update both the initial-equity and carrying-cost calculations.

Maintain a separate seller net-proceeds calculation. The buyer's equity contribution is not the seller's proceeds. In a purchase where the buyer assumes $100 million of debt, the debt portion of the price does not arrive as unrestricted cash to the seller. The settlement statement needs to distinguish price, retained debt, seller charges and adjustments.

A $1.675 million annual difference, or $6.7 million nominal over four unchanged years. That does not mean the seller can raise the price by $6.7 million. Hypothetical example from this guide. Before time value, taxes or other expenses. Not a quote or offer.

Negotiate what continues after the transfer

Identify obligations under the note, guaranties, environmental indemnities, cash-management agreements and other surviving documents. The seller should seek express releases covering the intended parties and obligations, with an agreed boundary for liabilities arising before the transfer. The buyer should understand which obligations it assumes and whether it indemnifies the seller separately.

The REMIC assumption definition permits multiple liability outcomes; it does not dictate the seller's release.[1] An indemnity from the buyer also differs from release by the lender. If the seller remains obligated to the lender, a buyer indemnity depends on the buyer's ability and duty to reimburse the seller if a claim arises.

The ICNQ agreement authorizes an original-borrower release in specified assumption circumstances.[2] That provision should not be treated as an automatic release of every original guarantor or indemnitor. Require the closing documents to name the released parties and describe the scope rather than relying on a summary approval email.

Reconcile fees, reserves and existing defaults

Request a complete fee and cost schedule. Separate assumption charges, legal costs, rating-related expenses, third-party diligence and reserve changes. CREFC's glossary identifies assumption and modification fees as possible additional servicer compensation under a pooling and servicing agreement.[4] It does not establish a uniform amount or eliminate other transaction expenses.

Determine how existing escrows, security deposits, reserve balances and open repair obligations transfer. If restricted funds remain with the loan, the purchase agreement needs to specify the economic credit and the buyer's ability to use them. Neither party should count the same balance as both a price adjustment and available closing cash without a funds-flow reconciliation.

Identify uncured defaults or reporting deficiencies early. A request to assume a loan while also obtaining waivers or changed economics may require a different approval path. In the ICNQ agreement, changing loan terms through an assumption is subject to its modification provisions.[2] The assumption request should describe the whole proposed package.

Before signing a firm closing timetable, align the purchase agreement's financing conditions, deposit exposure and outside date with the review process. The assumption succeeds when the property transfer, replacement credit support, funds movements and intended releases become effective together. Its value should be measured by that complete outcome, not the existing coupon alone.
