Intro

Mortgage rates are one of the biggest factors in your monthly payment, but there's more to them than just the number you see online. Here are 5 things to know about interest rates.

1. Rates Change Daily

Mortgage rates can move from one day to the next based on market conditions. That's why the rate you see today may not be available tomorrow.

2. Fixed & Adjustable Rates Work Differently

A fixed-rate mortgage keeps the same interest rate for the life of the loan, while an adjustable-rate mortgage may change over time based on market conditions.

3. Credit Score Influences Your Rate

Your credit score is one factor lenders consider when determining your interest rate. Generally, stronger credit profiles qualify for more favorable pricing.

4. Rate Locks Protect You

Once you're under contract, a rate lock protects you from market increases while your loan is being processed.

5. Discount Points Can Lower Your Rate

Some borrowers choose to pay discount points at closing in exchange for a lower interest rate. Whether that makes sense depends on your long-term plans.

Outro

Understanding how interest rates work helps you make more informed decisions instead of focusing on just one number.
