What does it take to buy an entry-level home in San Marcos today? For the bottom quartile of sales in September, the median price was $342,500 across 50 closed transactions. At a current mortgage rate of 7.32% from the Freddie Mac Primary Mortgage Market Survey, a buyer faces a principal and interest payment of $1,882 per month based on the ALEX Intelligence estimate parameters. ALEX Intelligence applied a standard affordability model to this price tier to determine buying power. The calculation uses the median entry-level price of $342,500 and the 7.32% note rate. This monthly cost represents the baseline for buyers targeting homes in the lowest price quartile of the market. While prices have risen 9.1% compared to August and 2.4% from September last year, the higher interest rate environment increases the monthly burden. Buyers must weigh the $342,500 median against the $1,882 payment requirement. The data shows that even at this entry level, financing costs are a significant factor in total affordability. The sample of 50 closed sales provides a clear view of what is currently available for first-time or budget-conscious buyers. This figure represents the threshold where homes transition from entry-level to mid-range pricing in San Marcos. Want a closer look? Reply or call George at 713.918.9951 and we'll set up a showing.
