Mortgage Rates Explained
Mortgage rates move every day, and the rate you lock has a bigger effect on your total cost than almost any other number in the deal. The headline average you see quoted in the news is close to meaningless for any individual borrower: your state, credit score, loan type, down payment and the points you are willing to pay up front all move the number you will actually be offered.
When comparing offers, look past the headline rate: points change the math (paying two points up front for a lower rate only pays off if you keep the loan for years), and the same rate can come with very different closing costs. Once you have a realistic rate, run it through the mortgage calculator to see the monthly payment and the full amortization schedule it implies — that's the number your budget will actually feel.
