Rates & Points
The interest rate determines the monthly interest payments over the lifetime of the loan. A "point" or "discount point" is equivalent to 1% of the loan amount and usually reduces or "discounts" the loan rate by an eighth of a percentage point.
You want to get a loan for $100,000 to buy a home. Each "point" would cost you 1% of $100,000 or $1,000 but would reduce your loan's interest rate by .125%. The lender might offer you an 8.0% loan with zero points, a 7.875% loan with one point, or a 7.75% loan with 2 points.
Points, like the down payment, are paid at closing. In some cases, lenders will allow borrowers to finance the points over the term of the loan. Lenders sometimes use points to make their interest rates appear lower. Be aware that lower interest rate offered by a lender may translate into higher points requirements.
