Over 30 million people in the U.S.A. have credit scores low enough (less than 620) to make shopping for low mortgage loan rates very difficult at best. The major credit reporting agencies use a slightly different system to arrive at a credit score. The best known is called the FICO score, developed by Fair Isaac and Company (FICO). A FICO credit score can range from 300 to 800. Most borrowers fall into the 600-800 credit score range.

A high FICO score is your reward for paying bills on time. This is one of the most important factors that determine your California home mortgage loan rate

If you've had a few credit bumps in the road recently, and you're asking yourself, How can I improve my FICO credit score? Here are 5 ways to boost your FICO credit score.

1. Paying your bills on time is the first step in improving your FICO credit score. Late payments can have a big negative impact on your FICO score, 30 days or more late on one account can lower your FICO score 50 points or more.

If you don't like writing checks, go online and automate your bill paying.

2. Don't max out your credit cards. The smaller balance gives you a wider difference between your balance and your credit limit.

Also, if you are planning to purchase a new car or other major item, wait until you get that low mortgage loan rate.

3. If you are sincerely interested in improving your FICO credit score, bankruptcy MUST be avoided! Bankruptcy is more negative than late payments or collection accounts.

4. Get credit counseling if you have too much debt and begin to fall behind, or can't see a way out.

5. Keep old paid off accounts in an open status. If you close an account, it won't help your FICO score but it could lower your credit score.

If you close an old account it could make you look like a rookie in the credit world. A factor in obtaining credit is how long you've had credit.

If your FICO credit scores are over 620, but you want to raise it, obtain a copy of your credit report and request that the credit bureau remove any errors.
