Round Rock: How Mortgage Rates Shape Buying Power in October

What does a 7.32% mortgage rate mean for a buyer in Round Rock today? With the median home price at $405,000 across 142 closed sales in September, the monthly principal and interest payment on a loan with a 7.32% note rate is $2,226. This figure represents the baseline cost of financing before any rate adjustments. ALEX Intelligence modeled two common buydown scenarios to show how buyers can temporarily reduce their monthly burden. A 3-2-1 buydown lowers the interest rate to 4.32% in year one, cutting the monthly payment by $619 for that first year at a total cost of $15,096. Alternatively, a 2-1 buydown reduces the rate to 5.32% in year one, saving $423 monthly for a total cost of $7,668. These costs represent 3.73% and 1.89% of the median sale price, respectively. The current market environment shows that while prices have risen 6.1% compared to last September, the higher interest rate environment increases the monthly payment burden significantly compared to lower-rate periods. Buyers must weigh the upfront cost of a buydown against their long-term cash flow goals. These calculations are ALEX Intelligence estimates based on median data and are not appraisals. The data reflects 142 closed sales in September, with the median price per square foot at $192.
