When you're getting ready to buy a home, your credit score is one of the most important numbers in the process. It influences your interest rate, your loan options, and in some cases whether you qualify at all. The good news: you don't need perfect credit to buy a home. The not-so-good news: the minimum score varies depending on which loan program you use — and every point counts when it comes to the rate you'll receive.
Minimum Credit Scores by Loan Type
Different mortgage programs have different floor requirements. FHA loans — backed by the Federal Housing Administration — allow scores as low as 580 with a 3.5% down payment, or as low as 500 with a 10% down payment. Conventional loans (Fannie Mae/Freddie Mac) generally require a minimum score of 620, though you'll need 740+ to access the best pricing tiers. VA loans technically have no government-mandated minimum, but most lenders (including Lumen) look for at least a 580–620. Jumbo loans, which exceed the conforming loan limits, typically require 700 or higher — often 720+ for the best terms. USDA loans are similar to FHA and generally require a 640 minimum for streamlined processing.
How Your Score Affects Your Rate
The difference between a 680 and a 740 credit score isn't just about qualifying — it can mean thousands of dollars over the life of your loan. Lenders price mortgage rates using Loan Level Price Adjustments (LLPAs), which are fee grids tied to your credit score and loan-to-value ratio. For example, on a $500,000 conventional loan, moving from a 679 score to a 700 score might reduce your rate by 0.25–0.50%, saving you $75–$150 per month. Over a 30-year loan, that's $27,000–$54,000 in total interest. It's worth taking 3–6 months to improve your score before you apply if you're on the edge of a pricing tier.
What Actually Makes Up Your Credit Score
Your FICO score is calculated using five weighted factors: Payment history (35%) — the single biggest factor; whether you've paid bills on time. Amounts owed (30%) — your credit utilization ratio, or how much of your available credit you're using. Lower is better; aim for under 30%, ideally under 10%. Length of credit history (15%) — how long your accounts have been open. Don't close old cards right before applying. Credit mix (10%) — a variety of account types (cards, auto loans, student loans) signals experience managing debt. New credit (10%) — hard inquiries from recent applications can temporarily ding your score. Avoid opening new accounts in the 6 months before you apply.
How to Improve Your Score Before Applying
The fastest ways to boost your score: Pay down revolving balances — even dropping your utilization from 50% to 20% on one card can move your score 30–40 points within one billing cycle. Dispute errors — pull your free reports from AnnualCreditReport.com and dispute any inaccuracies; errors are more common than you'd think. Become an authorized user — if a family member has an old card with a clean history and low utilization, being added as an authorized user can add that positive history to your file. Avoid new credit — every hard inquiry is a small negative signal; resist the urge to open store cards or auto loans in the months before you apply for a mortgage.
Does Checking Your Own Credit Hurt You?
No — checking your own credit is a 'soft inquiry' and has zero impact on your score. Only 'hard inquiries' — when a lender pulls your credit during an application — can affect your score. The good news is that mortgage-related hard inquiries within a short window (typically 14–45 days, depending on the scoring model) are treated as a single inquiry, so shopping multiple lenders doesn't multiply the damage.
Run the Numbers First
FHA Loan & MIP Calculator
Abstract percentages are easy to read past. Seeing your actual monthly number — principal, interest, and FHA mortgage insurance — is something different. A good loan calculator turns a rate quote into a real budget you can stress-test before you ever talk to a lender.
With our FHA calculator you can model the full picture: vary your purchase price and interest rate, choose any down payment from 3.5% to 20%, and instantly see how each choice affects your monthly payment, total MIP cost, and whether your mortgage insurance cancels at 11 years or stays for the life of the loan. Layer in property taxes and homeowners insurance to arrive at a true all-in monthly budget.
Down payment impact
See how 3.5% vs. 10% vs. 20% affects your MIP rate, monthly payment, and total mortgage insurance cost.
