Make sure your credit is in orderThere’s no more important time to work on your credit score than when you’re about to apply for a mortgage. Improving your credit can save you a ton ofmoney‐we’re talking about thousands of dollars over the life of the loan. Here are the actions you can take that will have a notable impact on your score.Pay down your credit card balances Credit utilization is one of the biggest factors in determining your credit score. Your credit utilization should at least be lessthan 30 percent of your limit, and it’s even better if you can get it below 15 percent. This rule applies to both individual cards and your overall credit limit.It may even be worthwhile to use some of the cash funds you were planning to use for a down payment to pay off credit card balances.Do no harm While you certainly want to improve your score if possible, at the very least you’ll want to keep it steady. Avoid opening new lines of credit if you’reapplying for a mortgage in the very near future. This will cause a hard inquiry to show up on your credit report.Take care of negative items It’s good practice to check your credit report for negative items a few times a year‐you can get one free report from each of thethree major bureaus ﴾Experian, Equifax, and TransUnion﴿ per year.If you find any negative items ﴾collections, late payments, etc.﴿, write a letter to the original creditor. Explain the circumstances that led to the negative item, andrequest that it be removed from your report. It can be surprisingly effective, and removing a negative item will improve your credit score in a hurry. You can findsome good templates for a request letter online.
