Ask ten loan officers what credit score you need to buy a home and you’ll get ten slightly different answers. The number shifts with the loan program, the size of your down payment, and how nervous your lender feels that quarter.
A more useful question is the one that applies to your situation: what score do you need for the house you actually want, and what’s the fastest honest way to get there? Here’s how to work it out, in the order that matters.
Start With the Number Your Lender Will Actually Use
The score your mortgage lender pulls is not the score in your banking app. Most lenders order three “mortgage scores” (FICO Score 2 from Experian, FICO Score 4 from TransUnion and FICO Score 5 from Equifax) and use the middle one. These models weight your file differently from the VantageScore that free credit apps show you, so the two numbers can sit 20 to 40 points apart. A 640 on a free app might be a 612 where it counts.
Before you change anything, spend the $20 to $30 on a mortgage FICO report or ask a broker to run your file. Every step after this depends on knowing your real starting point.
The Minimum Score by Loan Type
- Conventional loans: 620 is the standard floor for Fannie Mae and Freddie Mac-backed loans, and 3% down is allowed at that score. Below 620, this door closes.
- FHA loans: 580 gets you in with 3.5% down. Between 500 and 579 you can still qualify, but you’ll need 10% down.
- VA loans: the VA sets no minimum, though most lenders add their own at 580 to 620.
- USDA loans: typically 640.
- Jumbo loans: 700 to 720 is common, and many lenders want 740 or better once the loan gets large.
Those floors tell you whether you’re allowed in. They say nothing about the price you’ll pay once you’re inside, which is where the real planning starts.
Step 1: Price Out What Your Score Costs You
Say you’re buying a $310,000 house with $31,000 down, leaving a $279,000 mortgage. In a market where the best advertised rates sit near 6.5%, here’s roughly what different scores buy you on a 30-year fixed conventional loan:
- 640 score: about 7.375%, or $1,934 a month in principal and interest
- 720 score: about 6.625%, or $1,793 a month
That’s $141 a month, or close to $51,000 across the life of the loan, for the same house, the same down payment and the same borrower. Now add the mortgage insurance gap. At 640 you might pay 1.1% of the loan annually, around $256 a month. At 760 the same coverage could run $117. A 60-point score difference can easily cost $300 a month.
Run this math before you shop, because it tells you whether waiting three months is worth it. It also changes what you can afford, since a higher payment drags your debt-to-income ratio up and shrinks your price ceiling. Working through the full cash you’ll need at closing alongside your projected rate gives you a realistic target instead of a wish list.
Step 2: Attack Credit Utilization First
If you need points quickly, revolving balances are where they come from. Utilization is the second-biggest factor in your score and the only one you can move in a single billing cycle.
Picture a card with a $5,000 limit carrying $2,400. That’s 48% utilization, and it’s dragging your file down. Pay it to $450 and you’re at 9%. On a score in the mid-600s, that single move often produces a 30 to 45 point jump once the new balance reports, usually within 30 days.
Time the payment to your statement date
Card issuers report the balance on your statement closing date, not the due date. Paying on the 28th when your statement cuts on the 30th does nothing for that cycle. Look up your statement date, pay five days before it, and you’ll see the change on the next report.
If you can’t clear the balance, spread it. Moving $800 off a card sitting at 60% utilization and onto a card at 10% lowers your overall ratio and generally helps more than it hurts.
Step 3: Handle Errors and Late Payments Deliberately
Pull all three reports and read them line by line. Roughly one in five files contains an error serious enough to affect a score, and mortgage underwriters will find them whether or not you do.
Disputes
The bureau has 30 days to investigate a dispute. Collections that aren’t yours, accounts reported late when you paid on time, and balances that don’t match your statements are all worth challenging in writing. Expect 30 to 45 days for the correction to land.
Goodwill letters
A single 30-day late payment can knock 60 to 80 points off a strong score. If it was a one-off and the rest of your history with that creditor is clean, call and ask whether they’ll remove it as a courtesy. It costs you a phone call, and a written goodwill letter sometimes works when the phone call doesn’t. Budget 30 to 60 days for an answer.
What you should not do is open new credit, close old cards or finance a car between now and your application. New accounts lower your average account age and add inquiries at the worst possible moment. A furniture store card opened in March can be the reason a June pre-approval comes back with a worse rate.
Step 4: Map Your Timeline Before You Apply
Scores move on a schedule, and knowing it stops you from applying too early. Here’s a rough guide for different problems, assuming you fix everything else:
- High card balances: 30 to 45 days after the new balance reports
- Report errors: 30 to 45 days from filing the dispute
- A single late payment removed by goodwill: 30 to 60 days
- Older late payments with no removal: the damage fades noticeably after 24 months and disappears at 7 years
- Chapter 7 bankruptcy: 2 years for FHA and VA, 4 years for conventional
- Foreclosure or short sale: 3 years for FHA, 4 to 7 for conventional
This is the stage where the order of operations matters most. Disputes, paydowns and rate shopping all take time, and they don’t overlap neatly. Sketching them against the home buying process from pre-approval to closing day will show you whether your target closing date is realistic or a stretch.
Step 5: When the Score Won’t Move in Time, Compensate
Maybe you’re six weeks from the end of a lease and your file has a two-year-old collection that isn’t going anywhere. You still have options.
- A larger down payment reduces the lender’s risk and can offset a weaker score
- An FHA loan with a non-occupant co-borrower, such as a parent, is allowed and can carry the file
- Manual underwriting at a credit union or portfolio lender weighs your whole picture instead of a cutoff
- Compensating factors like six months of reserves or a debt-to-income ratio under 35% can push an approval through
- Discount points buy the rate down, though they don’t change the score itself
Comparing lender-by-lender credit score minimums is worth an afternoon here, because overlays vary far more than most buyers expect. Two lenders can quote the same loan program with minimums 40 points apart.
Your 90-Day Countdown
Days 1 to 7: get your mortgage FICO scores and pull all three reports. Days 8 to 14: file disputes and send any goodwill letters. Days 15 to 45: pay every revolving balance below 10% utilization, timed to statement dates. Days 46 to 75: let the dust settle. No new accounts, no balance transfers, no car loans. Even a pre-qualified offer you never take can cost you. Days 76 to 90: gather pay stubs, W-2s, bank statements and tax returns, then get pre-approved.
One detail people miss: your score has to hold until closing, not just until pre-approval. Lenders commonly re-pull credit before funding, and a financed truck between contract and closing has killed plenty of deals.
A mortgage was never only about a credit score. Down payment, closing costs, reserves and your debt-to-income ratio all carry weight, and how much to save before you buy is often the harder constraint. Nail the score first, then build the cash cushion around it.
