The 2/1 Buy Down Mortgage allows the borrower to qualify at below market rates so they can borrow more. The initial starting interest rate increases by 1% at the end of the first year and adjusts again by another 1% at the end of the second year. It then remains at a fixed interest rate for the remainder of the loan term. Borrowers often refinance at the end of the second year to obtain the best long term rates; however, even keeping the loan in place for three full years or more will keep their average interest rate in line with the original market conditions. Acceleration Clause
Provision in a mortgage that allows the lender to demand payment of the entire principal balance if a monthly payment is missed or some other default occurs.
