CMBS property releases and partial defeasance

A property release removes an asset or portion of an asset from the mortgage lien. A partial defeasance substitutes eligible collateral for an identified part of the loan's real-estate security. Neither should be modeled as simply subtracting an allocated loan amount from sale proceeds. The owner needs to establish the permitted route, the required funding and the condition of the remaining collateral.

An allocated loan amount is a contractual input used in a portfolio's release mechanics. It may differ from the asset's value, its share of NOI and the amount the lender requires for release. Read the release schedule together with remaining-portfolio tests and any securitization conditions.

Identify the contractual route for the proposed sale

Determine whether the documents permit release through principal repayment, defeasance or another specified arrangement. Record the eligible assets, release amount, notices, permitted dates and required opinions. A provision permitting full defeasance does not by itself establish a right to partial defeasance.

A February 2025 mortgage-loan purchase agreement illustrates seller representations addressing principal-funded partial releases and partial defeasance, plus limited releases of certain unimproved portions.^[1] It contains particular allocation multiples and conditions. Those terms describe specified loans; they do not establish a universal CMBS release premium or authorize a sale under another agreement.

Treat an outparcel release separately from a full property's sale. Determine whether the parcel has assigned value, supports access or utilities, or affects zoning and operating use. The same purchase agreement's limited outparcel representation addresses value, access and zoning.^[1] Even an apparently unused parcel can have a role in the remaining property's legal or operational condition.

Model the remaining portfolio as a new credit question

Calculate remaining NOI, value, loan balance, coverage and debt yield after the sale and required funding. Use the agreement's defined income and expenses. An asset producing a large share of portfolio income can be more consequential than an allocation schedule suggests.

Include shared infrastructure and expenses. If disposing of one property leaves management or central expenses largely unchanged, subtracting that property's standalone NOI may overstate the remaining portfolio's income. Identify leases, service contracts and guarantees that continue after release, and adjust the operating budget accordingly.

Separate contractual credit tests from federal tax tests. The REMIC regulation's continued-real-property-security test generally compares current real-property value with 80 percent of the modified obligation's adjusted issue price, with an alternative comparison of post- and pre-modification collateral value.^[2] That is not a standard 80 percent LTV lending limit. Adjusted issue price is a tax measure and need not equal stated principal.

Apply overlapping tests without double counting

Consider a hypothetical $160 million portfolio loan. The asset to be sold has a $45 million allocated loan amount. Assume the contract initially requires a principal repayment equal to 120 percent of that allocation, or $54 million. Assume gross sale proceeds of $75 million and $3 million of sale expenses, leaving $72 million before release funding.

After the initial repayment, $106 million of debt remains. Assume remaining defined NOI of $9.5 million and a hypothetical minimum remaining debt yield of 9.50 percent. The maximum remaining balance under that test is $100 million: $9.5 million divided by 9.50 percent. An additional $6 million repayment is therefore required under the assumed credit test, bringing total release principal to $60 million.

Now assume remaining real-property value of $82 million and, solely for this illustration, adjusted issue price equal to the remaining principal. Before the additional $6 million payment, value is approximately 77.36 percent of the $106 million adjusted issue price, below the regulation's 80 percent route. Reducing adjusted issue price to $102.5 million would reach 80 percent, a $3.5 million reduction from $106 million.

The larger $6 million repayment already required by the credit test produces a $100 million balance and an 82 percent value-to-adjusted-issue-price result. On those assumptions, the owner does not add another $3.5 million to the $60 million payment. The selected conditions overlap. Net cash after sale expenses and the required $60 million principal repayment is $12 million, before other transaction charges.

This example assumes the 80 percent route is being used, with no other qualifying route applied. It is a calculation of selected tests, not a complete legal determination. IRS Revenue Procedure 2010-30 provides additional lien-release treatment for qualifying transactions, including specified qualified paydowns when the regulation's continued-security tests are not met.^[3] Counsel and the servicer must evaluate the actual route and adjusted issue price.

Treat partial defeasance as a collateral transaction

If partial defeasance is available, obtain a separate quote for the collateral needed to support the relevant payment stream, plus transaction costs. The securities price is not necessarily identical to the allocated amount or release amount. Identify exactly which loan payments the substituted collateral must support and what obligations remain secured by the unsold real estate.

Chatham's explanation describes securities supporting remaining debt payments and the related successor and account arrangements.^[4] The documents determine whether and how those mechanics apply to a partial transaction. Payment dates, permitted securities and the required horizon affect the price; a principal-only estimate can materially understate funding.

Do not count collateral substitution as principal amortization unless the transaction actually repays principal. A lender's property-release calculation, the note's outstanding balance and the real-estate-supported portion of the debt can be different measures. Reconcile them explicitly so the remaining-property model neither omits payments nor credits a nonexistent paydown.

Address REMIC requirements before marketing the asset

The regulation expressly governs when releasing a real-property lien can affect qualified-mortgage treatment and separately identifies qualifying defeasance conditions.^[2] A release needs an applicable route. A negotiated right should be written to operate within those constraints rather than depending on a discretionary waiver that the servicer may lack authority to grant.

Revenue Procedure 2010-30's qualified-paydown provisions include several defined ways to establish the required amount, including certain net proceeds and value-based measures.^[3] The relevant definitions are tax-specific. A closing statement's ordinary net-cash subtotal should not be assumed to satisfy the procedure without applying those definitions and the rest of its scope.

Obtain a preliminary release analysis before agreeing to a sale whose economics depend on retaining proceeds. Provide current value evidence, defined NOI, an allocation schedule and the proposed funds flow. Ask the servicer to distinguish credit conditions, tax conditions, document requirements and estimated costs. The MLPA representations themselves contemplate tax compliance or an appropriate tax opinion for specified releases.^[1]

Update the analysis when price, closing date or remaining performance changes. A release that worked in the original acquisition model can consume more cash after values or NOI fall. The sale is financially useful only if the resulting liquidity and remaining debt structure support the owner's plan after every applicable condition has been satisfied.
