How to Build Credit Before Buying a Home (2027)

You build credit by having accounts that report to the three credit bureaus, paying each one on time, keeping card balances low against their limits, and giving them time to age. Payment history (35%) and amounts owed (30%) make up most of a FICO score, and FICO can't score you until an account has been open six months. If you want to buy a home in 2027, start now. This guide covers building credit from scratch or rebuilding it, and what the 2026–2027 mortgage scoring changes mean for you.

Tactic	Impact	Timeline
Pay every account on time	Payment history is 35% of FICO	Ongoing; a late payment can be reported for up to 7 years
Keep reported card balances low	Amounts owed are 30% of FICO	Shows when the next statement reports
Dispute / remove inaccurate items	Fixes errors only; accurate negatives stay	Bureau generally investigates within 30 days
Secured credit card	Builds card history if the issuer reports to all 3 bureaus	FICO needs 6 months of history to score
Credit builder loan	Builds installment history and savings	Typically repaid over 6–24 months
Become authorized user on old card	Can help, but is not the same as your own accounts	When the issuer next reports
Space out new credit applications	One inquiry usually costs under 5 FICO points	Counts for 1 year, shows for 2

Why credit matters for a 2027 mortgage

Your credit decides whether you qualify, how much you can put down, and what the loan costs; Fannie Mae and Freddie Mac charge upfront fees that vary by score. Program floors as of October 2026:

• FHA: 580 or higher for 3.5% down; 500 to 579 is limited to 90% loan-to-value (10% down). See our FHA loan guide.
• Conventional: Fannie Mae's Desktop Underwriter dropped its fixed 620 minimum for casefiles created on or after November 16, 2025. A score is still required, and many lenders keep their own minimums.
• VA: the VA sets no minimum score; lenders do. See our VA loan guide.

More detail by program: what credit score you need to buy a house.

The same habits raise every model, but your scores can differ by model. The newer ones use trended data (how balances move over time) and, FHA notes, rent and utility payments when reported. At pre-approval, ask which model your lender uses.

Step 1: Pull your reports and fix errors

All three bureaus offer free reports every week at AnnualCreditReport.com, the only authorized site per the FTC. Beware look-alike sites. Then read every line:

• Errors (an account that isn't yours, a wrong balance, a paid account showing open): dispute in writing with the bureau and the company that reported it. The bureau generally has 30 days to investigate.
• Accurate negatives can be reported for seven years, a bankruptcy up to ten. Disputing them won't remove them.
• Medical collections: the bureaus no longer report paid medical collections or ones under $500, and they wait a year on unpaid medical debt. Since 2024, Va. Code § 59.1-444.4 also bars Virginia health care providers and medical-debt collectors from reporting medical debt.

Skip paid credit repair. The FTC says these firms can't remove true information or legally charge before doing the work, and you can do anything they do yourself for little or no cost.

Step 2: Keep reported balances low

Amounts owed are 30% of a FICO score, led by utilization: the share of your card limits in use. The CFPB says many experts recommend staying under 30%, and people with the highest scores often use less than 10%. You don't need to carry a balance; paying in full helps your score and avoids interest.

• The statement balance is usually what gets reported, so paying before the statement closes lowers it.
• A limit increase lowers utilization too. Ask whether the request triggers a hard inquiry.

Step 3: Pay on time and let accounts age

Payment history is 35% of a FICO score, and a late payment can stay on your report for seven years. Set autopay for at least the minimum on every account. Length of history adds 15%, and time is the one thing you can't rush.

• Keep old, no-fee cards open. Closing one removes its limit and pushes utilization up. A small recurring charge keeps it active.
• Think twice about co-signing. A co-signed loan is your debt too; its payments can land on your report and count in your debt-to-income ratio.

Step 4: Space out new credit

New credit is 10% of a FICO score. FICO says one inquiry takes less than five points off for most people; it counts for a year and shows for two. Checking your own credit never hurts. Mortgage rate shopping is protected: inquiries within 14 days (older FICO versions) or 45 days (newer) count as one.

Open accounts early in your plan. In the three to six months before you apply, hold off on new cards, store financing and car loans, and keep it that way through closing, since many lenders re-check credit before closing.

Step 5: Start or thicken a thin file

No accounts, or just one? These are the main ways to start, per the CFPB:

• Secured credit card: a cash deposit sets your limit. Confirm it reports to all three bureaus, compare fees, and ask whether it graduates to a regular card.
• Credit builder loan: mostly from banks and credit unions. The money is held while you repay it over 6 to 24 months, adding installment history.
• Authorized user on a family member's long-standing, on-time card. It can help, but the CFPB cautions it won't necessarily build your own history.
• Rent and utilities count only if reported. Experian Boost adds them to your Experian file free, but Experian notes not all lenders use scores Boost affects. Fannie Mae's underwriting can consider 12 months of on-time rent for some borrowers.

Debit cards, prepaid cards and payday loans don't build credit.

Realistic timeline

Point gains vary too much to promise, but the clock is predictable:

Month 1: Reports pulled, disputes filed, a reporting account opened, autopay set. Lower balances show on the next statement; dispute results generally follow within about 30 days.

Month 6: A new file can get its first FICO score.

Months 6 to 12+: On-time history builds and old late payments weigh less. From scratch, plan on a year or more before applying.

3 to 6 months out: Freeze new accounts and talk with a few Hampton Roads mortgage lenders. For local program details, read building credit before buying in Hampton Roads.

Frequently Asked Questions

How long does it take to build credit to buy a house?

FICO needs six months of history to produce a score. From scratch, plan on a year or more of on-time payments. With existing credit, lower balances and fixed errors can show within a statement cycle or two.

What is the minimum credit score to buy a house in Virginia?

There's no state minimum. FHA allows 500 with 10% down or 580 with 3.5% down; Fannie Mae's underwriting has no fixed 620 floor since November 2025; the VA sets none. Many lenders set higher cutoffs. Full credit score breakdown.

Will paying off collections raise my credit score?

It depends on the model. FICO Score 9 and VantageScore 4.0 ignore paid collections, but the Classic FICO versions most mortgage lenders pull (FICO Scores 2, 4 and 5) predate that change. Ask your loan officer first, and get any settlement terms in writing before you pay.

Can I get a mortgage with no credit history?

Sometimes. FHA allows borrowers with non-traditional or insufficient credit through manual underwriting, and Fannie Mae can weigh rent history for some borrowers. Expect more paperwork.

Does paying my rent build credit?

Only if it's reported, through your landlord, a rent-reporting service or Experian Boost. Most landlords don't report by default.

How often should I check my credit?

Your reports are free weekly at AnnualCreditReport.com. Free apps are handy for trends but often show a VantageScore or FICO Score 8, not the score a mortgage lender uses.

Will applying for a mortgage hurt my credit?

Slightly; one inquiry usually costs under five FICO points, and mortgage inquiries within a 14- or 45-day window count as one.

What's the difference between FICO and VantageScore?

Competing scoring models built from the same credit reports. Classic FICO has been the mortgage standard; Fannie Mae and Freddie Mac now also accept VantageScore 4.0, and FHA adds VantageScore 4.0 and FICO 10T in January 2027.
