What does a 7.4% mortgage rate mean for a buyer in Round Rock today? With the median closed sale price at $417,500 across 140 transactions in September, ALEX Intelligence calculated that a standard purchase requires a principal and interest payment of $2,313 per month. This rate, sourced from the Freddie Mac Primary Mortgage Market Survey for the week ending October 8, 2026, significantly impacts monthly affordability compared to lower-rate environments.
Buyers often ask if temporary buydowns are worth the cost. A 3-2-1 buydown on this median price reduces the rate to 4.4% in year one, saving $640 per month, though it costs $15,612 upfront. Alternatively, a 2-1 buydown drops the rate to 5.4% for the first two years, saving $437 monthly at a cost of $7,932. These figures represent ALEX Intelligence estimates based on current market data and are not appraisals.
The median price per square foot in Round Rock stands at $192, down 3% from last year, while the median home size has grown slightly to 2,089 square feet. Despite higher rates, sales volume remains robust with 140 closings in September, up 6.4% from the prior month and 9.4% from the same period last year. Understanding these payment scenarios helps buyers navigate a market where financing terms are as critical as the home price itself.
