How Credit Scores Affect Your Mortgage — and What to Do About It
Your credit score is the single biggest factor lenders use to price and approve a mortgage. It determines which loan programs you qualify for, how favorable your terms are, and — for some borrowers — whether you qualify at all. Here's exactly how that works.
Which credit score do lenders actually pull?
Most people have dozens of credit scores depending on the model and bureau. For a mortgage, lenders pull a tri-merge report — one from each of the three major bureaus (Equifax, Experian, TransUnion) — and use the FICO scoring model specific to mortgage lending (FICO 2, 4, or 5, depending on the bureau).
If you're buying with a co-borrower, lenders typically use the lower of the two borrowers' middle scores as the qualifying score. So if your score is strong but your co-borrower's isn't, that matters significantly.
This is worth knowing before you rely on Credit Karma or a bank's consumer app. VantageScore and general-purpose FICO versions often read differently from what a lender sees. Mortgage pre-approval is usually the first time borrowers see their actual lender-facing score — and sometimes the surprise goes in either direction.
How does your score affect which loan programs you can use?
Different loan programs have different score floors. Here's how they stack up:
Conventional loans (backed by Fannie Mae or Freddie Mac) generally require a minimum score around 620. Getting in the door is one thing — but pricing improves materially as you move up from that floor.
FHA loans (backed by HUD) are more flexible by design. Borrowers with scores at or above 580 qualify for FHA's standard down payment requirement. Scores between 500 and 579 may still qualify under FHA guidelines, but face a higher required down payment. Below 500, FHA isn't available.
VA loans technically have no agency-set minimum score, but most lenders set their own overlays — typically in the 580–620 range. If you're buying near Edwards Air Force Base or elsewhere in the Antelope Valley, the VA loan guide for Edwards AFB homebuyers covers the full picture.
Non-QM loans are portfolio products, so each lender sets its own requirements. They can serve borrowers who fall outside conventional or government-backed guidelines and often have more credit flexibility. Non-QM loans are worth understanding if your profile doesn't fit the standard boxes.

Does your credit score affect your mortgage pricing?
Yes — and this is where the real money is.
Mortgage pricing is risk-based. Both Fannie Mae and Freddie Mac use a system of Loan Level Price Adjustments (LLPAs) — cost adjustments applied based on your credit score, loan-to-value ratio, and loan type. The higher your score, the lower those adjustments, and the better the pricing you qualify for.
In practice: two borrowers applying for the same loan amount on the same property in Palmdale or Lancaster can receive meaningfully different offers based purely on a score gap. That pricing difference compounds over the full loan term. It's one of the strongest financial arguments for cleaning up your credit before you apply, rather than after.
For a fuller look at how lenders set rates beyond just the score, understanding mortgage rates covers what actually moves the needle — score is one input, but the bond market, loan type, and property type all factor in too.
What actually moves your credit score?
FICO scores are built from five factors, each weighted differently:
- Payment history (~35%) — The single biggest driver. One 30-day late payment can drop a healthy score sharply and stays on your report for years.
- Amounts owed / utilization (~30%) — How much of your available revolving credit you're using. Staying under 30% is a common benchmark; under 10% is better. Paying down a card before applying can move the needle in 30–60 days.
- Length of credit history (~15%) — Older accounts help. Closing old cards usually hurts here.
- Credit mix (~10%) — A blend of installment loans and revolving accounts signals experience managing different debt types.
- New credit (~10%) — Hard inquiries and recently opened accounts cause a temporary dip.
One important exception: multiple mortgage-related hard pulls within a short window (14–45 days, depending on the FICO version) count as a single inquiry. Shopping multiple lenders won't stack against you the way opening three credit cards would.
How do you improve your score before applying?
The highest-impact moves, in rough order:
- Pay everything on time. One missed payment right before closing can kill an approval outright.
- Pay down revolving balances. The fastest lever available to most borrowers. Reducing balances directly lowers utilization, which is the second-biggest factor.
- Don't open new accounts. Every new line is a hard inquiry and signals risk to lenders reviewing your file.
- Don't close old accounts. Closing a card removes available credit and increases your utilization ratio — and doesn't erase the history.
- Dispute errors. Credit reports contain errors more often than people realize. Check your report at annualcreditreport.com for accounts you don't recognize, incorrect balances, or duplicates.
- Give it time. A 90–180 day runway of clean behavior can produce meaningful score movement if the underlying issues are resolved.
What if my credit score is low — do I still have options?
Often yes. The path depends on how low and why.
For scores in the 580–620 range, FHA is usually the first conversation. Before assuming it's the better deal, read conventional vs. FHA — FHA carries mortgage insurance premiums that conventional avoids, so the math isn't always obvious.
For investors, DSCR loans qualify based on a property's rental income rather than personal credit and income — and often have more flexible score requirements. They're common with California real estate investors who don't fit the W-2 mold.
If you're a first-time buyer in Los Angeles County or the Antelope Valley with a thinner credit file, there are first-time homebuyer programs designed specifically to bridge that gap.
The bottom line: if your score isn't where you want it, the move is to understand where you are and build a plan — not to wait indefinitely. See where you stand and we'll map out the options that fit your timeline.
Frequently asked questions
Does checking my own credit hurt my score?
A soft pull — checking your own credit or a lender pre-qualification — doesn't affect your score. A hard inquiry from a full application does cause a small, temporary dip. Multiple mortgage inquiries within a short window count as one inquiry under FICO's rules, so shopping lenders won't hurt you the way multiple new credit card applications would.
What is considered a good credit score for a mortgage?
It depends on the loan type. FHA programs were designed to serve borrowers in the 580–620 range. Conventional programs become more accessible and more favorably priced as scores climb above the minimum. For most programs, scores above 740 put you in the most favorable pricing tier — though "good enough to qualify" and "best available pricing" are two different bars.
Can I get a mortgage after a bankruptcy, foreclosure, or short sale?
Yes, but timing and loan type matter. Government-backed programs (FHA, VA, USDA) have mandatory waiting periods that vary by event type. Non-QM products often have shorter or more flexible seasoning requirements. Talk to a broker about your specific timeline — the answer is almost never "never."
Does a larger down payment offset a lower credit score?
Partially. A larger down payment reduces your loan-to-value ratio, which can offset some pricing adjustments tied to a lower score. But it won't satisfy minimum score requirements — if you're below a program floor, LTV alone won't open that door.
Should I pay off debt or save for a down payment first?
Usually the move is to pay down revolving balances enough to lift your score meaningfully, then pivot to down payment savings — since a higher score often improves both your program options and your pricing. The right sequence depends on your specific numbers. Run the scenarios through our calculators or talk to a broker who can model both paths side by side.
