Mortgage & Home Loans

What is Fixed-Rate Mortgage?

A fixed-rate mortgage locks in your interest rate for the entire loan. Your monthly principal and interest payment stays the same from day one to the final payment—no surprises if market rates spike.

Predictability makes this the most popular mortgage type in the US. Most people choose 15 or 30 years. A 15-year term means higher monthly payments but a lower rate and faster payoff.

The trade-off: your rate won't drop automatically if market rates fall. You'd need to refinance to capture lower rates, which means new closing costs.

PRACTICAL EXAMPLE
