What Determines Your Mortgage Rate?
Mortgage rates are not one-size-fits-all. The rate you receive depends on a combination of market conditions and your personal financial profile. Understanding these factors gives you leverage when shopping for a home loan.
Market Factors
Federal Reserve Policy: The Fed does not set mortgage rates directly, but its actions heavily influence them. When the Fed raises its benchmark rate, mortgage rates typically follow.
Bond Market: Mortgage rates closely track the yield on 10-year Treasury bonds. When bond yields rise, mortgage rates tend to rise with them.
Inflation: Higher inflation generally pushes mortgage rates up because lenders need to maintain returns that outpace rising prices.
Economic Conditions: During recessions, rates tend to fall as demand for borrowing decreases. In strong economies, rates often rise.
Personal Factors
Your individual rate depends on several factors you can influence:
- Credit Score: Borrowers with scores above 760 typically receive the best rates. A score of 620 vs 760 can mean a difference of 1% or more on your rate.
- Down Payment: Putting down 20% or more usually qualifies you for better rates and eliminates PMI.
- Debt-to-Income Ratio: Lenders prefer a DTI below 36%. Lower ratios signal lower risk and earn better rates.
- Loan Type: Conventional, FHA, VA, and USDA loans each come with different rate structures.
- Property Type: Primary residences get the best rates, followed by second homes, then investment properties.
Fixed Rate vs Adjustable Rate Mortgages
Fixed-Rate Mortgages lock in your interest rate for the entire loan term. Your payment never changes, making budgeting predictable. These are ideal when rates are historically low or when you plan to stay in your home long-term.
Adjustable-Rate Mortgages (ARMs) start with a lower introductory rate that adjusts periodically after an initial fixed period. A 5/1 ARM, for example, has a fixed rate for 5 years, then adjusts annually. ARMs can save money if you plan to sell or refinance before the adjustable period begins.
How Small Rate Differences Add Up
On a $350,000 mortgage over 30 years:
| Rate | Monthly Payment | Total Interest |
|---|---|---|
| 5.5% | $1,987 | $365,415 |
| 6.0% | $2,098 | $405,434 |
| 6.5% | $2,212 | $446,488 |
| 7.0% | $2,329 | $488,520 |
The difference between 5.5% and 7.0% is $342 per month and over $123,000 in total interest.
Tips for Getting the Best Rate
- Improve your credit score before applying. Pay down credit cards and fix any errors on your report.
- Shop multiple lenders. Rates can vary by 0.5% or more between lenders on the same day.
- Consider buying points. Paying 1% of the loan amount upfront typically reduces your rate by 0.25%. This pays off if you keep the loan long enough.
- Lock your rate once you find a good deal. Rate locks typically last 30 to 60 days.
