How Do I Build My Credit to Buy My First Home?
The short answer
Start by pulling your free credit reports and fixing any errors. Then pay every bill on time, keep your card balances low compared to your limits, and avoid opening a lot of new accounts before you apply. If you have little credit history, a secured card or a credit builder loan can help, and some lenders can now consider your on-time rent. Talk with a lender early, since each loan program sets its own credit rules.
Why Does My Credit Matter So Much When I Buy?
How do you build your credit to buy your first home in Orange County? You build it the same way anyone does, with on-time payments, low balances and a clean report, and you start months before you plan to apply for a loan.
I'm Jeanette Nelson, a REALTOR® with Jeanette Nelson Real Estate, Keller Williams Realty, serving Orange County, Huntington Beach, Costa Mesa, Fountain Valley, and surrounding areas. Credit is one of the first things I encourage first-time buyers to look at, because it shapes which loans you can use and what rate you are offered.
This is general information, not lending or credit advice. A lender or a HUD-approved housing counselor can review your own file with you.
How Do I See Where My Credit Stands Today?
Pull your credit reports first. The Consumer Financial Protection Bureau (CFPB) says you can get free reports from each of the three nationwide credit bureaus once a week at AnnualCreditReport.com.
The CFPB also warns to be cautious of other websites that claim to offer free credit reports. Use the official site.
When you read your reports, look for:
- Accounts you don't recognize
- Late payments you believe were on time
- Balances or limits that look wrong
- Old debts that should have aged off
What Builds Credit the Fastest?
The CFPB says paying your bills on time, every time, has the greatest impact on your score. Set up automatic payments or reminders so nothing slips.
Next is how much of your available credit you use. The CFPB explains that scoring models look at how close you are to your limits, and it notes that experts often advise using no more than 30% of your total credit limit. Paying your full balance each month also keeps your interest cost low.
A few other habits help:
- Keep older accounts open. The CFPB notes your score tends to improve the longer you have credit.
- Go slow on new credit. The CFPB says your score may go down if you apply for or open a lot of new accounts in a short time.
- Be careful when closing cards. Closing cards and moving balances onto one card can raise the share of your limit you are using.
What if I Don't Have Much Credit History Yet?
That is common for first-time buyers. The CFPB describes two tools:
- A secured credit card. You put down a deposit equal to your limit. As you show on-time payments, the limit may rise and the deposit may be refunded.
- A credit builder loan. The lender holds the loan amount in a savings account while you pay it back, often over 6 to 24 months.
With either one, the CFPB suggests checking that your payments will appear on your credit report.
Your rent may also help. Fannie Mae has a positive rent payment program that lets its underwriting system consider on-time rent payments, often found through bank statements. Ask your lender whether it uses this option.
How Do I Fix Errors on My Credit Report?
The CFPB says to dispute an error with both the credit bureau and the company that reported it. Explain in writing what is wrong and why, and include copies of your supporting documents, never originals.
The CFPB notes the credit bureau generally has 30 days to investigate. Start this early, since a correction can take time to show up.
If an error comes from identity theft, the CFPB points people to IdentityTheft.gov.
What Credit Score Do I Need to Buy a Home?
It depends on the loan. HUD's FHA guidance says a borrower with a decision credit score of 580 or higher can qualify for maximum financing, and FHA's down payment can be as low as 3.5%. With a score from 500 to 579, HUD limits the loan to 90% of the value, which means at least 10% down.
Conventional loans follow Fannie Mae and Freddie Mac rules, and those rules have changed recently. Fannie Mae's Selling Guide now relies on its own underwriting system's credit review for many loans instead of a single fixed minimum. A lender can tell you exactly where you stand.
Credit also affects your rate and costs, not just approval. Once you know your numbers, see how much should I save to buy my first home and what will I pay at closing.

Frequently asked questions
How long does it take to build credit for a mortgage?
It varies. The CFPB notes that recent negative information affects your score more than older information, so steady on-time payments help more over time. A lender can tell you how your file looks today.
Does checking my own credit hurt my score?
Pulling your own reports at AnnualCreditReport.com is how the CFPB recommends you review them. Applying for many new accounts in a short time is what the CFPB says can lower your score.
Can I buy a home with no credit score?
Some lenders can use other records. Fannie Mae's positive rent payment program can consider on-time rent, and rules vary by loan. Ask a lender what applies to you.
Should I pay off all my cards before applying?
Lower balances compared to your limits usually help. Talk with your lender before moving large sums, because they also need to see the savings for your down payment and closing costs.
