The most common buydown is the 2-1 buydown. In the past, for a buyer to
secure a 2-1 buydown they would pay 3 points above current market points
in order to pay a below market interest rate during the first two years
of the loan. At the end of the two years they would then pay the old market
rate for the remaining term.
As an example, if the current market rate for a conforming fixed rate
loan is 8.5% at a cost of 1.5 points, the buydown gives the borrower a
first year rate of 6.50%, a second year rate of 7.50% and a third through
30th year rate of 8.50% and the cost would be 4.5 points. Buydown were
usually paid for by a transferring company because of the high points
associated with them.
In today's market, mortgage companies have designed variations of the
old buydowns rather than charge higher points to the buyer in the beginning
they increase the note rate to cover their yields in the later years.
As an example, if the current rate for a conforming fixed rate loan is
8.50% at a cost of 1.5 points, the buydown would give the buyer a first
year rate of 7.25%, a second year rate of 8.25% and a third through 30th
year rate of 9.25% , or a three-quarter point higher note rate than the
current market and the cost would remain at 1.5 points.
Another common buydown is the 3-2-1 buydown which works much in the same
ways as the 2-1 buydown, with the exception of the starting interest rate
being 3% below the note rate. Another variation is the flex-fixed buydown
programs that increase at six month interval rather than annual intervals.
As an example, for a flex-fixed jumbo buydown at a cost of 1.5 points,
the first six months rate would be 7.50%, the second six months the rate
would be 8.00%, the next six months rate would be 8.50%, the next six
months rate would be 9.00%, the next six months the rate would be 9.50%
and at the 37th month the rate would reach the note rate of 9.875% and
would remain there for the remainder of the term. A comparable jumbo 30
year fixed at 1.5 points would be 8.875%.
