When visiting open houses in the Northside and Stone Oak areas of San Antonio, I've noticed that visitors' first question has often shifted from property prices to mortgage rates.

Texas has a relatively stable income-to-home-price ratio, so inquiries about buying remain steady, but the speed at which these inquiries turn into actual contracts varies significantly with the level of interest rates. Therefore, I will summarize how mortgage rates move and what levels are currently worth noting in the market.

Mortgage rates are not determined by a single factor but are influenced by multiple variables. The most frequently mentioned factors include:

• 10-year U.S. Treasury yield - serves as a benchmark for long-term fixed-rate mortgages
• Federal Reserve's interest rate policy and monetary policy direction
• Inflation indicators (CPI, PCE) trends
• Supply and demand in the MBS (mortgage-backed securities) market
• Individual credit scores, DTI (debt-to-income ratio), down payment ratios

Among these, the 10-year Treasury yield is particularly important. Mortgage loans are often refinanced or repaid within about 10 years, so lenders base their rates on this Treasury yield plus a spread. While the mortgage rate does not move in lockstep with changes in the Fed's benchmark rate, the overall direction of monetary policy does influence market rates.

As of mid-2026, according to Freddie Mac PMMS statistics, the average rate for a 30-year fixed mortgage is observed to be in the mid to high 6% range. The 15-year fixed rate tends to be about 0.5 to 1 percentage point lower than the 30-year rate, as the shorter repayment period reduces the interest rate risk for lenders. However, the monthly payment for a 15-year fixed mortgage is significantly higher, so cash flow considerations must also be taken into account.

ARMs (adjustable-rate mortgages) often start with lower rates than fixed-rate mortgages for the first 5 or 7 years. This can be advantageous for those planning to sell or refinance after a short stay, but it is crucial to acknowledge the risk of rate adjustments after the fixed period ends. For long-term residents, fixed rates are generally considered a more stable option in terms of predictability.

The difference in rates based on credit scores is also quite noticeable during the contract process. Generally, the most favorable rates are offered for scores above 760, while rates tend to increase significantly as scores drop from the 620s to the 680s. The exact figures vary by lender and timing, so it is best to confirm through prior consultation.

San Antonio has a significant military population due to Randolph Air Force Base and Fort Sam Houston, making the use of VA loans relatively high in the area. VA loans, which can be obtained without a down payment, significantly reduce initial financial burdens if the eligibility requirements are met.

For Korean households, it is helpful to check credit reports at least six months before applying for a loan, maintain credit card usage below 30%, and prepare income verification documents (W-2, tax returns) in advance to aid in both the speed and conditions of approval. Comparing APRs from multiple lenders can also be practically beneficial in lowering overall costs.

Interest rates may continue to move gradually based on future economic indicators. Rather than focusing on short-term predictions, choosing loan products that align with one's financial situation and living plans is a more stable approach.
