Due-on-sale clauses – also called alienation clauses – are a type of acceleration clause. Similar to due-on-sale clauses, acceleration clauses allow your mortgage lender to demand full repayment of your home loan. The difference is that a due-on-sale clause is triggered when you sell or transfer your property without the lender’s consent, whereas an acceleration clause goes into effect when you miss mortgage payments, file for bankruptcy or fail to fulfill your loan requirements in some other way.
