For a buy down mortgage loan program, the interest rate and payment remain unchanged for a fixed period, at the end of which, the interest rate and payment both increase. The interest rate and payment may increase once, twice, or even three times, depending on whether the Buy-down is a 1/1, 2/1, or 3/1.
However, the percentage of increase, as well as number of increases is predetermined. Once all of the increases have occurred, the new rate and payment remain fixed for the term of the loan. Furthermore, lenders will as a rule charge a fee to buy the rate down for the first 1, 2, or 3 years of the mortgage loan.
Borrowers having troubles getting fixed-rate loans and seeking affordable payments are recommended to consider Buy Down loan programs.
