Credit Score to Buy a House: Requirements by Loan Type and How to Improve Yours Fast
Your credit score determines which loan programs you qualify for, what interest rate you receive, and how much PMI costs. A 20-point difference in score can change your monthly payment by $50–$150. Over 30 years that is $18,000–54,000. Understanding the minimum requirements is the first step; understanding how to improve your score quickly is the step that saves real money.
Credit Score Requirements by Loan Type
| Loan Type | Minimum Score | Standard Score | Score for Best Rate | ||||||
|---|---|---|---|---|---|---|---|---|---|
| Conventional (conforming) | 620 | 680+ | 740+ | ||||||
| FHA (3.5% down) | 580 | 620+ | 680+ reduces MIP somewhat | ||||||
| FHA (10% down) | 500 | 580+ | 620+ | ||||||
| VA | No official minimum; ~620 typical lender floor | 620+ | 740+ for best rates | ||||||
| USDA | No official minimum; ~640 typical lender floor | 640+ | 720+ | ||||||
| Jumbo (above $806,500) | 680–700 typical minimum | 720+ | 760+ | ||||||
| These are lender minimums, which can be higher than program minimums. Individual lenders set their own overlays above minimum guidelines. "Best rate" thresholds shift with market conditions. | |||||||||
How Lenders Calculate Your Score: The Tri-Merge
Lenders pull your credit report from all three bureaus: Experian, Equifax, and TransUnion. Each bureau generates a FICO score. Lenders use the middle score of the three (not the average, not the highest). On a joint application with two borrowers, lenders typically use the lower of each borrower’s middle score. If one borrower has 710 and the other has 660, the qualifying score is 660.

How to Improve Your Credit Score Fast: The Specific Steps
Step 1: Pay Down Credit Card Balances to Under 10% Utilization
Credit utilization (balance ÷ limit) is the single fastest-moving credit factor. If you have a card with a $5,000 limit and $2,500 balance (50% utilization), paying it to $450 (9% utilization) can add 20–60 points within one billing cycle. Target: below 10% on each individual card and below 10% total. This alone is frequently the highest-leverage action.
Step 2: Dispute Any Errors on All Three Reports
Pull your free reports from AnnualCreditReport.com. Check all three bureaus. Errors that affect mortgages: inaccurate late payments, accounts you don’t recognize, balances reported incorrectly, closed accounts showing as open. Dispute errors directly with each bureau. Resolution takes 30 days but can add 20–80 points if errors are significant.
Step 3: Do Not Open New Accounts or Close Old Ones
New accounts temporarily reduce average account age (lowers score) and add a hard inquiry. Closing old accounts reduces available credit (increases utilization). Both hurt your score. For 6 months before and during the mortgage process: no new credit cards, no new car loans, no closing any accounts.
Step 4: Become an Authorized User on a Seasoned Account
If a family member has a credit card with a long history, low utilization, and no late payments, being added as an authorized user can add that account’s history to your report. This is legitimate and is recognized by FICO. You don’t need to use the card — just being on the account adds the history.
Step 5: Address Any Collections Before Applying
A collection account with a recent payment date (even partially paid) can actually reduce your score further by refreshing the account’s "last activity" date. Before paying any collection, ask your lender whether it needs to be paid for loan approval and how to structure the payment to minimize score impact. Some programs require collections to be paid; others do not.
“The fastest score improvement I’ve seen was a buyer who went from 618 to 694 in 60 days. They did two things: paid their credit cards from 75% utilization to under 10%, and disputed three errors that were removing 40 points combined. That 76-point improvement dropped their FHA rate by almost 1% and saved them over $80,000 in lifetime interest. The time it cost them: 60 days. For most buyers with a score between 620 and 680, a 60–90 day improvement sprint before applying is almost always worth it.”

What credit score do I need to buy a house?
Minimum by loan type: conventional 620, FHA 580 (3.5% down) or 500 (10% down), VA and USDA ~620 (lender floor). Best rates start at 740+. For a first-time buyer, targeting 680–720 before applying typically provides a much better rate than applying at the minimum.
Which credit score do mortgage lenders use?
Lenders pull all three bureaus (Experian, Equifax, TransUnion) and use the middle score. On joint applications, they use the lower of the two borrowers’ middle scores. FICO Score 8 or 9 (versions) are most commonly used; FICO 10T is being phased in by Fannie Mae and Freddie Mac.
How fast can I improve my credit score before buying a house?
40–80 points in 60–90 days is achievable with targeted action: pay credit card utilization below 10%, dispute errors on all three bureaus, do not open or close any accounts. Utilization improvement shows in one billing cycle. Dispute resolutions take 30 days.
Does checking my own credit hurt my score?
No. Checking your own credit is a soft inquiry and does not affect your score. Only hard inquiries (from lenders, landlords, or credit card applications) temporarily reduce your score. Check all three bureaus free at AnnualCreditReport.com before starting the mortgage process.
