Understanding Mortgage Rates: How They Work and How to Get a Lower One
What drives mortgage rates, the difference between fixed and adjustable loans, and practical ways to secure a lower rate on your home loan.
Your mortgage rate quietly determines the true cost of your home. Understanding what moves rates — and what you can control — can save you a fortune over the life of your loan.
What drives mortgage rates
- The broader economy and inflation expectations
- Central bank policy and bond markets
- Your credit score and debt-to-income ratio
- Loan type, term, and down payment size
Fixed vs. adjustable-rate mortgages
A fixed-rate mortgage keeps the same rate for the life of the loan — predictable and popular. An adjustable-rate mortgage (ARM) starts lower but can rise after an introductory period. ARMs can make sense if you plan to move or refinance before the adjustment.
Rate vs. APR
The interest rate is the cost of borrowing the principal. The APR includes rate plus lender fees, giving a fuller picture of total cost. Compare APRs when shopping lenders.
How to get a lower rate
- Raise your credit score before applying
- Lower your debt-to-income ratio
- Make a larger down payment
- Compare offers from at least three lenders
- Consider buying discount points if you will stay long term
- Lock your rate once you find a good one
Frequently asked questions
Is it better to get a fixed or adjustable rate?+
A fixed rate offers stability and is ideal if you plan to stay long term. An ARM can save money upfront if you expect to move or refinance before it adjusts.
Do mortgage points make sense?+
Points lower your rate for an upfront fee. They pay off if you keep the loan past the break-even point — often several years — so they favor long-term owners.
