Due-on-sale clause

A clause in most mortgages saying the full balance becomes due if the property is sold or transferred. Why most conventional loans can't just be taken over by the next owner.

Part 1 of 4

Why a seller cares

Nearly every conventional mortgage has one, and it is why a buyer cannot quietly take over your payments. It also makes informal deals, a land contract or a wraparound, riskier than they look.

Part 2 of 4

A simple example

A buyer proposes taking over your $220,000 loan at 3% while you keep it in your name. Your loan's due-on-sale clause lets the lender call the whole balance if title transfers.

Due-on-sale clause: a simple example
What is proposedWhat the clause allows
Deeding the home while your loan staysThe lender may demand the full $220,000 at once
A formal assumption approved by the lenderAllowed; the clause is waived by the lender's own process
Paying the loan off at closingThe ordinary sale; the clause never comes up

The clause is the lender's veto over a change of owner. It is rarely used and always there.

Part 3 of 4

What people get wrong

That lenders never enforce it. They rarely need to, and a rate far below market is exactly the case where one might.
