Quick Answer
There is no single magic number, but there are practical floors. Conventional loans generally need a 620. FHA works from 580 with 3.5% down, and as low as 500 with 10% down. USDA has no official minimum, though most lenders want to see 620 to 640. VA has no official minimum either, though most lenders look for 580 to 620.
Getting past the floor is only half the game. Your credit score directly determines which loan programs you qualify for, what interest rate you will pay, and how much mortgage insurance will cost. A higher score means lower rates and more options.
A buyer with a 760 score may pay 0.5% to 1% less in interest than a buyer with a 640 score. That translates to $200 to $400+ per month and potentially $50,000 to $100,000+ over the life of a 30-year loan. Even a 20 to 30 point improvement can meaningfully reduce your rate and save you thousands.
What Credit Score Do You Actually Need? Minimums by Loan Type
Here are the practical floors for the four main loan programs, with the down payment note that goes with each. These are the numbers I quote most often when a first-time buyer asks me what score they need:
| Loan Type | Minimum Credit Score | Down Payment Notes |
|---|---|---|
| FHA | 580 standard 500 with 10% down | 3.5% down at 580; below that you need 10% down |
| Conventional | 620 typical | 3% down programs exist at 620; best rates reserved for 760+ |
| VA | No official minimum; most lenders want 580 to 620 | Zero down for qualified veterans and service members |
| USDA | No official minimum; most lenders want 620 to 640 | Zero down for eligible rural and suburban properties |
These are current general rules, and every lender adds its own overlay, so the "minimum" on a chart and the number a lender quotes you can differ. Confirm your exact situation before you shop with expectations built on a number you have not verified.
Credit Score Tiers and What They Mean
Credit scores generally fall into these tiers for mortgage lending:
- 760+: Best rates available, all loan programs open to you.
- 700 to 759: Very good. Slightly higher rates but excellent options across almost all loan types.
- 660 to 699: Good. Most programs available with a moderate rate premium.
- 620 to 659: Fair. Limited to FHA or conventional with higher rates and higher mortgage insurance.
- Below 620: Few options. FHA may still work down to 580 with 10% down.
The Real Dollar Impact of Your Score
This table is illustrative, but the shape is real: here is how your credit score affects your payment on a $350,000 30-year fixed-rate loan:
| Credit Score | Interest Rate | Monthly Payment | Extra Cost Over 30 Years vs. 760 |
|---|---|---|---|
| 760+ | 6.25% | ~$2,162 | Baseline |
| 700 to 759 | 6.50% | ~$2,219 | +$57/month · +$20,520 over 30 years |
| 660 to 699 | 6.75% | ~$2,276 | +$114/month · +$41,040 over 30 years |
| 620 to 659 | 7.25% | ~$2,387 | +$225/month · +$81,000 over 30 years |
Note: Rates are illustrative and do not include taxes, insurance, or mortgage insurance. Your actual rate depends on market conditions and your full financial profile.
Worked Example: A Half Point Is Tens of Thousands (Illustrative)
Say you are financing $320,000 on a 30-year fixed-rate loan. Principal and interest run roughly $2,023 a month at 6.5%, $2,076 at 6.75%, and $2,129 at 7.0%. The half point between 6.5% and 7.0% is about $106 a month, which adds up to roughly $38,000 in extra interest over 30 years. Even a quarter point, 6.5% to 6.75%, is about $19,000 over the life of the loan.
That is why raising your score before you apply pays. I had a client at 638 who qualified for FHA at 6.875%. We spent 60 days paying down two credit cards and disputing one error, her score jumped to 694, and she qualified for conventional at 6.25% instead. On her $320K loan that saved her $145 per month, or $52,200 over 30 years, from two months of credit work.
How Lenders Read Your Score: The Middle Score Rule
Mortgage lenders pull your credit from all three bureaus, Equifax, Experian, and TransUnion, and they typically use the middle score of the three for your approval and your rate. If one bureau reports something the other two do not, that low number can drag down the score that actually matters.
And here is what trips up a lot of buyers: the score you see in a free app is often a different model, like a VantageScore or a credit-card FICO variant, and it can run 20 to 50 points away from the mortgage FICO score lenders use. Do not obsess over the gap between the app and the lender's number. What matters is your mortgage score at underwriting, and once your rate is locked, the lock is the number that counts.
How to Check Your Credit Score
Before you start the home buying process, it is essential to know where your credit stands. Here is how to check:
- Get your free annual credit reports at annualcreditreport.com (official source)
- Many banks and credit card issuers provide free FICO scores through their apps and websites
- Check all three bureaus (Experian, TransUnion, Equifax) -- scores can differ by 20 to 50 points between them
Mortgage lenders use the middle score from all three bureaus. If one bureau has a significantly lower score than the other two, it could indicate an error that needs to be disputed.
How to Improve Your Score Before Applying
If your score is not where you want it to be, here are the most effective strategies, ranked by impact:
- Pay down credit card balances below 30% utilization (below 10% is ideal) -- this is the fastest-impact move you can make
- Dispute any errors on your credit reports (can take 30 to 45 days, but worth it)
- Do not close old credit cards -- length of history is a significant factor
- Do not open new accounts in the 6 months before applying
- Make every payment on time for at least 12 months
- Become an authorized user on a family member's old, clean card
- If you have collections, negotiate pay-for-delete before applying
That is the short version. If your score needs work, I have the full step-by-step plan with timelines, including what to do 6 to 12 months out versus 30 to 60 days out, in my guide on how to improve your credit score to qualify for a mortgage.
The 60 to 90 Day Credit Optimization Window
The single biggest lever you can pull is credit card utilization. Paying your cards from 80% utilization down to 10% can boost your scores 30 to 50 points within 30 to 60 days.
If you are 3 to 6 months from applying for a mortgage, this one move alone can be the difference between qualifying for FHA versus conventional, or between getting a rate that costs you thousands more over the life of the loan.
What If My Score Is Too Low Right Now?
Do not panic. Most credit issues are temporary and fixable. A structured 60 to 90 day plan can often boost scores significantly. In the meantime, get pre-approved to know exactly where you stand and what you would qualify for today. Then optimize.
Even if you do not qualify for your ideal loan today, knowing your starting point gives you a clear roadmap. I help buyers build a credit action plan all the time. The key is to start now, not later.
Patriot Pro Tip
Check your score early, not the week before you go under contract. A 20 to 40 point move can shift you into a different rate tier, and you only have leverage on your score before you apply. Pull your reports, fix what you can, and give the score time to catch up while you still have it.
Reality Bites
Your score is not everything. Lenders weigh your income, your debts, your assets, and your employment history right alongside it. A great score with a high debt-to-income ratio can still block the loan, and a so-so score with a strong file can get approved. The score opens the door; the rest of your file is what walks you through it. If you want the full picture of what lenders weigh, read my breakdown of debt-to-income ratios.
A Word of Caution
The minimums and rate tiers above are current general rules, not a quote. Lenders set their own overlays and programs change, so confirm your exact numbers with a lender before you plan around them. And remember: a lower score is not an automatic no. FHA and USDA in particular look at the whole file, and buyers at 580, even at 500 with 10% down, close loans every month.
