Assumable Loan

An assumable loan is multifamily debt that a buyer can take over from the seller at existing terms, rather than paying off and refinancing. Rare in commercial multifamily but valuable in rising-rate environments.

What it means in practice

Most modern commercial multifamily loans have "due on sale" clauses requiring payoff at transfer. Some agency loans and legacy CMBS allow assumption with lender approval and possibly a fee.

When interest rates have risen since the original loan was made, an assumable below-market-rate loan can be a significant value to the buyer — and a negotiating lever for the seller.

Why it matters for LA multifamily

For LA multifamily sellers in 2026 whose loans were originated at 2021 rates (3-4%), an assumable loan at those rates is a substantial asset when current rates are 6-7%. Check loan documents; if assumable, market this feature prominently. Can support 5-10% higher sale pricing when the rate differential is meaningful.
