Stop credit activity. Until you apply for a mortgage, it may be a good idea to cease most credit-related activity. That means you’ll want to skip any large purchases, avoid applying for any new accounts and try not to switch jobs or make any other major life changes.
Pay down balances. One of the most important factors in determining your credit score is the amount you owe compared to the amount of credit you have. Ideally, you don’t want to use more than 30 percent of your available credit. If you can, work to pay down balances if you’re using more than this.
Good credit can take time to build, but regularly reviewing your information and working to rectify past errors will put you in the best possible position when it comes to getting an optimal rate on your mortgage.
