Condo Deconversion Mortgage 2026: What Happens When a Condo Goes Back to Apartments

Condo deconversion occurs when a majority of condo unit owners vote to dissolve the condominium regime and sell the entire building to a single buyer, typically an investor planning to convert the units back to market-rate rentals. Deconversions have increased in markets where the rental economics of a building as a whole exceed the sum of individual unit sale prices.

How Deconversion Affects Financing

• ✦Once a deconversion vote is approved, the project is legally transitioning out of condominium status
• ✦Fannie Mae and Freddie Mac will not purchase loans on units in a project that has an approved deconversion pending
• ✦FHA will not insure new loans once a formal deconversion vote has been approved by the requisite majority of owners
• ✦Existing loans on affected units remain outstanding but new purchase or refinance financing is unavailable

Investor Concentration as an Early Warning

Long before a formal deconversion vote, financing problems can develop when a single investor acquires a large block of units. Fannie Mae restricts the percentage of units a single entity can own: no more than 20% in projects with 21 or more units. Fewer units allowed in smaller projects. When concentration exceeds these thresholds, the project becomes ineligible for new Fannie Mae purchase or refinance financing regardless of whether a deconversion vote has been called.

Protecting Active Files in the Pipeline

If you have a purchase or refinance in a condo complex and you hear that a deconversion vote is being circulated, order the HOA questionnaire immediately. Ask specifically whether any bulk investor purchase offers or deconversion votes are pending. Fannie Mae requires the HOA to disclose pending litigation and material ownership changes. A positive answer on deconversion will kill the file in underwriting.
