How to Build Your Credit Score Before Buying a Home

Your credit score plays a central role in the homebuying process. It determines whether you qualify for a mortgage, what interest rate you receive, and how much you pay over the life of your loan. Even a small improvement in your score can save you thousands of dollars. The good news is that most people can meaningfully improve their credit within six to twelve months of focused effort.

## Check Your Credit Reports First

Before you do anything else, pull your credit reports from all three major bureaus: Equifax, Experian, and TransUnion. You are entitled to one free report from each bureau every year through AnnualCreditReport.com. Review each report carefully for errors, such as accounts that do not belong to you, incorrect balances, or late payments that were actually made on time. Disputing and correcting errors is often the fastest way to boost your score.

## Understand What Makes Up Your Score

FICO scores, which are used by most mortgage lenders, are calculated from five categories. Payment history accounts for 35 percent of your score, making it the single most important factor. Amounts owed make up 30 percent, length of credit history is 15 percent, new credit inquiries account for 10 percent, and your credit mix makes up the remaining 10 percent. Knowing this breakdown helps you prioritize your efforts.

## Pay Every Bill on Time

Since payment history carries the most weight, making every payment on time is the single most impactful thing you can do. Set up autopay for at least the minimum payment on every account. Even one missed payment can drop your score significantly, and late payments stay on your report for seven years. If you have existing late payments, getting current and staying current will gradually improve your score over time.

## Lower Your Credit Utilization

Credit utilization is the percentage of your available credit that you are currently using. Lenders like to see this number below 30 percent, and below 10 percent is ideal. For example, if you have a credit card with a $10,000 limit, try to keep the balance below $3,000 at all times. You can lower your utilization by paying down existing balances, requesting credit limit increases on existing cards, or spreading purchases across multiple cards.

## Avoid Opening New Accounts

Every time you apply for new credit, a hard inquiry appears on your report and can temporarily lower your score by a few points. In the months leading up to a mortgage application, avoid opening new credit cards, financing furniture or appliances, or taking out auto loans. The exception is if you have no credit history at all, in which case a secured credit card or credit-builder loan can help establish a payment history.

## Keep Old Accounts Open

The length of your credit history matters. Closing old credit cards shortens your average account age and reduces your total available credit, both of which can hurt your score. Even if you no longer use an old card, keep it open and make a small purchase on it every few months to keep it active.

## What Credit Score Do You Need?

The minimum credit score requirements vary by loan type. Conventional loans typically require a 620 or higher. FHA loans accept scores as low as 580 with a 3.5 percent down payment, or 500 with 10 percent down. VA and USDA loans do not have a government-mandated minimum, but most lenders require at least 620. Keep in mind that higher scores unlock better interest rates and more favorable loan terms regardless of the loan type.

## Start Early

Give yourself at least six months before you plan to apply for a mortgage. This gives you time to dispute any errors, pay down balances, and establish a consistent payment history. If your score needs significant improvement, twelve months is a more realistic timeline. Many down payment assistance programs also require minimum credit scores, so improving your credit opens up more assistance options as well.
