How to Build Credit Before Buying a Home

Why Credit Matters When Buying a Home

Lenders evaluate three things on a mortgage: credit, income, and assets. You can have strong income and steady savings, but if your credit profile is thin or damaged, your loan options narrow and your costs go up. Credit also affects auto loans, credit cards, rental applications, utility deposits, insurance pricing in many states, and some employment screenings.

For first-time buyers, the gap between average and strong credit is real money. On a $400,000 loan, a half-point difference in interest rate is roughly $115 per month, or about $41,000 over a 30-year term. That's tied directly to a single number on your credit report.

How Credit Scores Are Calculated

FICO is the most widely used scoring model for mortgages. It weighs five categories. The first two carry 65% of the weight, so that's where the effort pays off the most.

What Credit Score Do You Need to Buy a Home?

Minimum credit requirements vary by loan program. Here's where they land in 2026.

The minimum gets you in the door. The score that affects your monthly payment is a different number. Conventional pricing is broken into "credit tiers," and each tier above the minimum can save tens of thousands of dollars over the life of the loan. If your score is in the 580-620 range, the priority is hitting 620 to unlock conventional and most DPA options. From 620 to 740, every 20-point gain typically saves money.

How to Build or Improve Your Credit

There's no shortcut, but there is a clear playbook. The strategies below are the ones that consistently move the score for first-time buyers.

1. Pay Every Bill on Time

This is the single most important factor in your score. A single 30-day late payment can drop a score 60 to 100 points and stay on your report for 7 years. Set up autopay for at least the minimum on every account, then pay off the full balance manually if you prefer that level of control. The goal is to make a missed payment functionally impossible.

2. Keep Credit Card Balances Low

Credit utilization is the percentage of your available credit that you're using. Lenders want to see this stay low.

• Under 30% utilization on each card and overall is the threshold to clear
• Under 10% utilization is where the strongest scores cluster
• 0% utilization across every card is not ideal, since some scoring models want to see active use

One practical move: pay your card down before the statement closes. The bureau only sees the balance reported on the statement date, not your post-payment balance.

3. Build a Longer Positive History

Length of credit history is 15% of your score, and it's one of the few factors you can't rush. The clock starts the day an account opens. Two implications: open a starter account as early as possible, and don't close old accounts. Closing a 10-year-old card resets the history clock for that line. Keep older cards open with a small recurring charge and pay them off each month.

4. Add Rent & Utility Payments to Your Credit Profile

Most renters pay thousands per year in rent, but those payments don't show up on a traditional credit report unless you take action. Rent reporting services verify your payments with your landlord and submit them to the credit bureaus on your behalf. The biggest impact is for renters with thin or limited files, since rent payment history adds depth and length to an otherwise sparse profile.

Rental Kharma* is one option to consider. They report rent payments to TransUnion and Equifax, and at signup they backfill the entire payment history of your current rental rather than starting from the enrollment date. They can also report utility payments (electric, gas, water, and phone) for an added fee. Setup involves a brief landlord verification, with no hard credit inquiry.

5. Use a Secured Credit Card to Establish Payment History

A secured credit card is the most common starting point for buyers with no credit, limited credit, or past damage. You put down a refundable deposit, which becomes your credit limit. From there, the card works like any other: charges, statements, and on-time payments reported to the bureaus.

Credit Builder Card* is one option built specifically for profile development. It has a $200 minimum refundable deposit (which sets your starting limit), reports to all three major credit bureaus, and approval does not require a traditional credit check (active bankruptcy is the main disqualifier). The card typically arrives within about two weeks of approval. After 6 to 12 months of responsible use on any secured card, many issuers will refund the deposit and convert the account to unsecured.

6. Dispute Errors on Your Credit Report

The Federal Trade Commission has reported that roughly 1 in 4 consumers find an error on at least one credit report. Common errors include accounts that aren't yours, incorrect balances, and late payments that were actually on time. Pull all three reports for free at AnnualCreditReport.com (the official site mandated by federal law) and dispute anything wrong directly with the bureau showing it. Bureaus have 30 days to investigate.

A Closer Look at Two Common Tools

Rent & Utility Reporting Services

If you've been paying rent on time, that's a long history of housing payments that traditional credit scoring largely ignores. Services like Rental Kharma* close that gap by verifying your payments with your landlord and submitting them to the credit bureaus.

How a typical rent reporting service works:

• Bureau coverage: Rent data goes to TransUnion and Equifax. Most rent reporting services do not currently feed Experian, so the impact may show up on two of your three reports rather than all three.
• Backfilling history: Many services, including Rental Kharma, will report the full payment history of your current rental at enrollment, not just future months. This is what adds length to a thin file faster than starting from scratch.
• Utility reporting: Some services can also report electric, gas, water, and phone bill payments for an additional fee, which can broaden your reported payment history beyond housing alone.
• Setup: Verification typically involves your landlord confirming the rental and payment history. There is no hard credit inquiry and no bank account connection required.
• Pricing: Most services charge a one-time setup fee plus a small monthly subscription. Compare current pricing on the provider's site before signing up.
• Cuts both ways: Once you are enrolled, late payments are reported too, so consistency matters.
• Scoring impact varies: Not every scoring model weights rent data the same way. The biggest gains tend to be for renters with thin files.

Secured Credit Cards

Secured cards differ in a few ways worth comparing before you pick one. Using Credit Builder Card* as a reference point, here are the variables that matter most:

• Bureau coverage: The strongest secured cards report to all three major bureaus (TransUnion, Equifax, and Experian). Credit Builder Card reports to all three, which gives the payment history broader pickup.
• Approval criteria: Some secured cards run a hard credit check, others do not. Credit Builder Card does not require a traditional credit check, which makes it accessible to people with no file or past damage. Active bankruptcy is generally the main disqualifier.
• Deposit: Compare the minimum deposit (Credit Builder Card starts at $200) and whether the deposit is fully refundable.
• Fees and APR: Some cards charge an annual fee, some do not. APR is less important if you pay the balance in full each month, which is the right strategy for credit-building anyway.
• Path to unsecured: Look at how long the issuer typically takes to review you for an upgrade and whether they refund your deposit when that happens.

The behavior that builds credit is the same on every card: keep the balance low and pay on time. A common pattern is to charge a small recurring expense (a streaming service or a utility bill) and pay it in full every month. That alone is enough to establish a positive history.

Common Mistakes That Hurt Credit

Some of the biggest setbacks come from well-intentioned moves. Avoid these:

• Closing old credit cards. Shortens your average account age and shrinks total available credit, spiking utilization.
• Maxing out a card and paying it off later. The high balance may already have been reported before your payment posts.
• Applying for several new cards in a short window. Each application is a hard inquiry and shortens average account age.
• Co-signing a loan you don't fully control. The account shows on your report, and missed payments hit your score.
• Paying off old collections without a plan. In some scoring models, paying re-ages the account and can lower the score temporarily. Talk to a lender first.
• Opening new credit right before a mortgage application. In the 6 months before a home purchase, avoid new accounts and large balance changes. Lenders re-pull credit before closing.
