Recently, observing the housing market in Victorville shows a steady flow of inquiries due to relatively affordable prices compared to the areas near LA. However, just as much as the sale price, the actual monthly payment is influenced by mortgage rates, and understanding how these rates are determined can put you in a much better position during the loan preparation process.

The most fundamental factor that influences mortgage rates is the yield on 10-year Treasury bonds. Since the funding maturity of a 30-year fixed mortgage has a similar long-term structure to Treasury bonds, the two yields generally move in the same direction. When Treasury yields rise, mortgage rates tend to follow suit after a lag, a pattern observed in various market conditions.

The Federal Reserve's decisions on interest rates are also a significant variable. When the Fed adjusts its benchmark interest rate, it changes the cost of funding between banks and the expectations of investors regarding inflation, which in turn affects mortgage rates. During periods when inflation indicators come in higher than expected, increased volatility in the bond market can lead to fluctuations in mortgage rates as well.

The supply and demand situation in the MBS market is also a factor reflected in actual consumer rates. Depending on how actively investors purchase mortgage-backed securities issued based on loans that have been executed, the spread between mortgage rates and Treasury yields can widen or narrow.

As of 2026, the average rate for a 30-year fixed mortgage is expected to be in the mid to high 6% range. The 15-year fixed mortgage tends to be lower, forming in the high 5% to low 6% range, making it a viable option for those who can manage the monthly payment burden while significantly reducing total interest costs.

ARM products often offer lower rates during the initial fixed period compared to 30-year fixed mortgages. However, after the adjustment period, the payment amounts can vary based on rate changes, making it more suitable for households planning to move or refinance within 5 to 7 years rather than those looking to hold long-term.

At the same time, even with the same lender, the rates offered can vary significantly based on credit scores.

• 760 and above: Tends to receive the lowest rate
• 700-759: Average rate
• 660-699: Higher than average rate
• Below 620: Tends to have stricter approval conditions

In areas like Victorville, where prices are relatively low, increasing the down payment ratio slightly can improve the DTI, often resulting in more favorable conditions during rate negotiations. Maintaining a low credit card balance and avoiding new loans at least six months before applying for a loan can help manage your credit score. Although comparing estimates from different lenders can be cumbersome, it is a necessary process that should not be skipped.
