011-0, 2-1, and 3-2-1 options
A 1-0 buydown reduces the effective rate for the first year. A 2-1 reduces it for the first two years, and a 3-2-1 may reduce it for three years. The payment increases according to the schedule until it reaches the full note-rate payment.
02Someone has to fund it
The buydown account is typically funded by the seller, builder, or another permitted party. Borrower-paid temporary buydowns may not be allowed, and program eligibility varies.
03You usually qualify at the note rate
The lender generally qualifies the borrower using the full note-rate payment, not the temporarily reduced payment. That helps confirm the mortgage remains affordable after the buydown period ends.
04Use concessions strategically
When seller or builder concessions are available, a temporary buydown may provide more useful short-term relief than leaving eligible funds unused. Compare it with permanent points, closing-cost credits, and price reductions before deciding.
05Ask me to run the numbers
The right choice depends on the cost, monthly savings, time horizon, loan program, and likelihood of refinancing or selling. Sometimes a little temporary relief makes the move much more comfortable.
