Becoming a homeowner has become increasingly more challenging, with the median monthly mortgage payment reaching an all-time high of $2,661 (at a 7.19% mortgage rate), according to Redfin.com. They also found the median sale price of a home to be $374,975. And sky-high mortgage rates have left both homebuyers and owners feeling increasingly pessimistic about the housing market outlook

So, if you're in the market for a mortgage or a refinance, it’s more important now than ever to ensure you can secure the lowest mortgage rate possible. One way you can find the best 30-Year mortgage rates is by prioritizing a good credit score.  

Credit score impact on mortgage rates 

Lenders take into account a variety of factors when determining the interest rate on your mortgage, including your down payment, desired loan term and the price of the property. However, the biggest factor determining your mortgage rate is your credit score. Most lenders will take into account your FICO score, which can range from 300 to 850, or from poor to exceptional credit.

How to improve your credit score

Your credit score matters to lenders as it shows them how likely you’ll be able to repay your loan. If you have a higher credit score, lenders won’t see you as a risky borrower. And while you can still get approved for a mortgage with a bad credit score, you won’t be able to secure the lowest rates possible. If you’re looking to save on your mortgage rates, try following these steps to boost your overall credit score before applying.  

Check your credit report: Before applying for a mortgage, get a copy of your credit report. You’ll be able to see a complete rundown of your credit history, helping you identify areas of your credit that are hurting your score, while also checking for any inaccuracies in the report. Having errors on your credit report is more common than you may think, so it’s important to get those fixed, by filing a dispute if any are found.

Make on-time payments: Payment history is the largest factor affecting your credit score, accounting for 35% of your total score. Because of this, it’s vital to always make payments on time, as missing payments can significantly decrease your score.

Pay off credit card balances: Credit utilization is the ratio between any debt you have compared to your total credit limit, and it makes up 30% of your overall credit score. Therefore, keeping your credit utilization ratio as low as possible can help you up your overall credit score. A good rule of thumb is to keep your credit utilization below 30%.
