An assumable mortgage lets a qualified buyer take over the seller’s existing mortgage — including its rate, term, and remaining amortization — instead of arranging new financing, subject to the lender's approval of the buyer.
Assuming a mortgage can appeal to a buyer when the seller's existing rate is more attractive than current market pricing, or as a way to help the seller avoid a prepayment penalty for breaking the mortgage early. The buyer still has to qualify with the lender — income, credit, and debt-service ratios are assessed as if applying fresh, just as with any new mortgage.
An assumable mortgage is a different concept from porting: porting moves the same borrower's existing mortgage to a newly purchased property, while assumption transfers the seller's mortgage obligation to a different borrower on the same property.
Not every mortgage is assumable: the mortgage contract must permit assumption, and the lender must approve the transaction before it can proceed.
Buyer must still qualify: the lender assesses the assuming buyer against its normal requirements, so the seller's agreement alone doesn't guarantee approval.
Can avoid a prepayment penalty: because the obligation transfers rather than being discharged, assumption can save the seller from paying to break the mortgage early.
Different from porting: porting moves an existing borrower's own mortgage to a new property, rather than transferring the mortgage to a new borrower.
