Should I buy mortgage points?
Points are an upfront fee (one point is 1% of the loan) to lower your interest rate. They pay off only if you keep the loan long enough to pass the break-even point. Points add to your cash to close, which ListingCraft for Buyers totals for you on the offer screen.
Divide the cost of the points by the monthly payment reduction to find how many months it takes to break even, and compare that with how long you expect to keep the loan.
