Mortgage rates can feel like a mystery — one week they tick up, the next they ease. Understanding what actually drives them helps you time your decisions with confidence instead of guesswork.
Rates track the broader bond market, especially the 10-year Treasury yield, along with inflation data and Federal Reserve policy. Lenders then layer in their own pricing based on loan type, credit profile, and down payment.

Why your rate differs from the headline rate
The rate quoted in the news is an average. Your actual rate depends on your credit score, loan-to-value ratio, property type, and program — which is why two borrowers can be quoted very different numbers on the same day.

Locking your rate
Once you’re under contract, a rate lock protects you from market swings during escrow. Locks typically run 30 to 60 days, and many lenders offer a float-down if rates improve before closing.

The takeaway
Don’t try to time the market perfectly. Focus on the monthly payment you’re comfortable with, lock when the numbers work, and remember: you can often refinance later if rates fall.
