Overview

What determines your mortgage rate?

Mortgage rates are not random. They respond to a handful of market forces, lender dynamics, and your personal financial profile. Understanding what drives them helps you lock at the right time and avoid surprises.

The Fed does not set mortgage rates directly, but its decisions on the federal funds rate ripple through the bond market. When the Fed raises or lowers rates, mortgage-backed securities typically shift in response, influencing the rates lenders offer.

Mortgage rates tend to track the 10-year Treasury yield, since both are long-term investments. When Treasury yields rise, mortgage rates usually follow. When yields fall, lenders can pass savings to borrowers.

Your credit score and loan-to-value ratio are the biggest personal levers. A 740+ score and 20% down payment typically unlock the best pricing. Lower scores or higher LTVs add risk-based adjustments.

Conventional loans, FHA, VA, and jumbo programs each carry different rate profiles. Shorter-term loans (like 15-year fixed) usually offer lower rates than 30-year terms, but with higher monthly payments.
