Buying down points involves paying an upfront fee at closing to secure a lower interest rate for either a temporary period or the entire life of the loan. Core Mechanics of Mortgage Points

: You can ask the home seller or builder to pay for your points as a closing incentive, effectively buying down your rate at no upfront cost to you.

: One point typically costs 1% of your total loan amount . Example: For a $300,000 loan, one point costs $3,000.
