What does a 7.32% mortgage rate mean for a buyer in Williamson County today? With the median home price at $390,000 across 835 closed sales in September, the monthly principal and interest payment on a standard loan is $2,143. ALEX Intelligence modeled two common buydown scenarios to show how these rates affect affordability. A 3-2-1 buydown reduces the rate to 4.32% in year one, cutting the monthly payment by $595 compared to the standard rate. This buydown costs $14,520 total, or about 3.72% of the median sale price. A 2-1 buydown offers a smaller reduction, lowering the rate to 5.32% in year one for a monthly savings of $407, at a total cost of $7,380, or 1.89% of the price. These figures assume a 30-year fixed loan and do not include taxes, insurance, or HOA fees. The data reflects September 2026 closed sales, with mortgage rates sourced from the Freddie Mac Primary Mortgage Market Survey for the week ending October 22, 2026. Buyers should treat these modeled payments as estimates to compare financing options, not as appraisals of specific properties. Want a closer look?
