Key Takeaway: Your credit score is the single biggest factor lenders use to set your mortgage interest rate. The difference between a 620 and a 760 score on a $350,000 loan can cost you more than $60,000 in extra interest over 30 years. Understanding the minimums — and the rate tiers — helps you decide whether to apply now or spend a few months improving your score first.
Minimum Credit Score Requirements by Loan Type
There is no single universal minimum. The score you need depends on which loan program you are using. Here is how the four main programs compare:
Conventional Loan
620
Minimum FICO Score
- Backed by Fannie Mae / Freddie Mac
- Best rates at 740+
- PMI required below 20% down
- No upfront mortgage insurance premium
FHA Loan
580
Minimum (3.5% down) — 500 with 10% down
- Government-backed, lower bar to qualify
- MIP required for life of loan (if <10% down)
- Flexible debt-to-income limits
- Good option for recovering credit
VA Loan
No official minimum
Most lenders require 620 in practice
- Available to eligible veterans & service members
- No down payment required
- No monthly PMI
- Competitive rates even at lower scores
USDA Loan
640
Typical lender requirement
- For rural and suburban properties
- No down payment required
- Income limits apply
- Guarantee fee instead of PMI
Important Distinction: The minimum score to qualify and the score needed for the best rate are very different numbers. A 620 may get you a conventional loan, but it will come with a rate that is 1.5% to 2.5% higher than what a borrower with a 760 score pays. That difference has a massive dollar impact over 30 years.
How Your Credit Score Affects Your Mortgage Rate
Lenders use your FICO score to determine which interest rate tier you fall into. Fannie Mae and Freddie Mac publish Loan-Level Price Adjustments (LLPAs) that translate directly into higher rates for lower scores. The table below shows representative 30-year fixed APRs by score range as of early 2026 for a $350,000 purchase with 20% down. Your actual rate will vary by lender, loan size, and market conditions.
| FICO Score Range | Rate Tier | Typical 30-Yr APR | Monthly Payment | Total Interest (30 Yr) |
| 760 and above | Best | 6.50% | $1,896 | $402,560 |
| 720 – 759 | Very Good | 6.75% | $1,946 | $420,560 |
| 680 – 719 | Good | 7.00% | $1,996 | $438,800 |
| 640 – 679 | Fair | 7.50% | $2,098 | $475,280 |
| 620 – 639 | Minimum | 8.00% | $2,201 | $512,440 |
Rates are illustrative based on market conditions. Loan amount: $280,000 (80% LTV on $350,000 purchase). Rates change daily; consult lenders for current quotes.
The Real Cost of a Lower Score: $350K Mortgage Example
Let's put the rate difference in concrete dollar terms. Comparing a borrower with a 760 score versus one with a 620 score, both buying the same $350,000 home with 20% down:
Score 760 vs. Score 620 on a $280,000 Loan (30 Years)
Borrower A — Score 760 — 6.50% APR
Monthly payment (principal + interest) $1,896
Total paid over 30 years $682,560
Total interest paid $402,560
Borrower B — Score 620 — 8.00% APR
Monthly payment (principal + interest) $2,201
Total paid over 30 years $792,440
Total interest paid $512,440
$109,880
Extra interest paid over 30 years with a 620 vs. 760 score
That is roughly $305 more per month — every month for 30 years. If you are sitting at 620 and could realistically reach 680 or 720 within 6 to 9 months of focused credit work, the math of waiting almost always wins.
Credit Score vs. Down Payment Tradeoff
Your credit score and down payment interact in two important ways: they both affect your rate, and a larger down payment can sometimes compensate for a weaker score.
| Scenario | Score | Down Payment | PMI Required? | Rate Outlook |
| Best case | 760+ | 20%+ | No | Lowest available |
| Strong buyer | 720–759 | 10–19% | Yes | Near best |
| Average buyer | 680–719 | 5–9% | Yes | Moderate premium |
| Marginal buyer | 620–679 | 3.5% (FHA) | Yes (MIP) | Significant premium |
A larger down payment (25%+) can offset some LLPAs from a lower score, but it cannot eliminate them entirely. If you are choosing between saving more for a down payment versus spending time improving your credit score, focus on the score first if you are below 700. The rate reduction from a better score typically outweighs the PMI savings from a larger down payment at the margin.
How to Improve Your Score Before Applying: 6–12 Month Timeline
Credit improvement is methodical, not magic. Here is what to focus on and roughly when to expect results:
Month 1–2
Pull your credit reports and dispute errors Get free reports from all three bureaus at AnnualCreditReport.com. Look for accounts you do not recognize, incorrect balances, duplicate collections, or outdated negative items. Dispute any errors in writing. Bureaus have 30–45 days to investigate. Accurate removals can boost your score immediately.
Month 1–3
Pay down revolving balances aggressively Credit utilization (balance ÷ limit) accounts for 30% of your FICO score. Getting all cards below 30% utilization can add 20–50 points. Getting below 10% often adds another 10–20 points. Pay down the card with the highest utilization ratio first, not necessarily the highest balance.
Month 2–6
Establish a perfect on-time payment streak Payment history is 35% of your score. If you have missed payments, you cannot remove them if accurate, but you can bury them with a consistent streak of on-time payments. Set up autopay for every account. Even one new 30-day late can set your score back 60–100 points.
Month 3–9
Address collections and charge-offs strategically Unpaid collections under $500 are excluded from new FICO models but may still affect older scoring models lenders use. Before paying a collection, request a pay-for-delete agreement in writing. If the collector agrees, you pay and they remove the tradeline. Use a debt validation letter to verify the debt is yours and the amount is accurate before agreeing to pay anything.
Month 6–12
Do not open or close accounts Opening a new credit card lowers your average account age and adds a hard inquiry — both hurt your score temporarily. Closing old accounts reduces your available credit and can spike utilization. In the 6 to 12 months before a mortgage application, keep your credit profile static.
Soft Pull vs. Hard Pull: What Happens When You Shop Lenders
Many borrowers avoid shopping for mortgage rates because they fear damaging their credit with multiple inquiries. This fear is largely unfounded when you understand how mortgage inquiries actually work.
The 45-Day Rule: FICO treats all mortgage-related hard inquiries within a 45-day window as a single inquiry. You can get quotes from 10 lenders in 45 days and your score only takes the hit of one hard pull — typically 5 to 10 points, which recovers within a few months.
Soft pull (pre-qualification, rate checkers): Does not affect your score, not visible to other lenders. Use these tools freely to get a rough sense of your rate before committing.
Hard pull (formal mortgage application, pre-approval): Recorded on your report, visible to other lenders for 2 years, can lower your score slightly. Triggers when a lender pulls your full credit file to issue a Loan Estimate.
The practical advice: Get soft-pull estimates from several lenders to narrow your list, then submit formal applications to your top 2–4 choices within the same 45-day window. Comparing rates across lenders on a $350,000 mortgage can save $30,000 to $80,000 over 30 years — far outweighing any temporary score impact.
Common Mistakes That Hurt Your Score Before Closing
Getting pre-approved is not the end of the credit scrutiny. Lenders run a final credit check immediately before closing. These moves between application and closing have derailed or delayed thousands of mortgage closings:
Do Not Do These After Applying: - Open a new credit card or loan — New accounts lower your average account age and change your debt-to-income ratio. Even a new store card for a couch can jeopardize your closing.
- Make large credit card purchases — Running up your existing cards increases your utilization and your minimum monthly payment, changing the DTI ratio your lender calculated.
- Change jobs or go self-employed — Lenders verify employment right before closing. A job change can require re-underwriting the entire loan. Moving from W-2 to self-employed is particularly risky.
- Co-sign any loan for another person — Co-signing adds that loan to your credit file and raises your DTI, even if you never make a payment.
- Make large unexplained deposits — Lenders scrutinize your bank statements. Cash deposits that cannot be sourced raise red flags for anti-money-laundering compliance and can stall closing.
- Miss any existing payment — One 30-day late after application can drop your score 60–100 points and void your loan approval outright.

What credit score do I need to buy a house?
The minimum depends on loan type. Conventional loans require 620+. FHA loans allow 580 with 3.5% down or 500 with 10% down. VA loans have no official minimum but most lenders require 620. USDA loans typically require 640. To get the best interest rate on any loan type, aim for 740 or higher.
Does shopping multiple mortgage lenders hurt my credit score?
No — not if you shop within a 45-day window. FICO treats all mortgage-related hard inquiries during that period as a single inquiry. You can compare rates from 5 to 10 lenders without additional score damage. Always shop; a 0.25% rate difference on a $350,000 mortgage saves over $18,000 over 30 years.
How long does it take to improve my credit score before applying for a mortgage?
Most meaningful improvements take 6 to 12 months. Paying down card balances can show results in 30 to 60 days. Disputing errors takes 30 to 45 days per round. If you are below 620 and targeting a conventional loan, plan for 6 to 18 months of focused credit work before applying.
What should I avoid doing after applying for a mortgage?
Do not open new credit accounts, make large credit card purchases, change jobs, co-sign any loans, or miss any existing payments. Lenders re-check your credit before closing. Any of these actions can change your debt-to-income ratio or credit profile enough to delay or cancel your approval.
What is the difference between a soft pull and a hard pull on my credit?
A soft pull does not affect your score and is used for pre-qualification estimates. A hard pull is recorded on your report, visible to other lenders, and can lower your score by 5 to 10 points temporarily. Use soft-pull tools to shop rates, then trigger hard pulls only when you are ready to proceed with formal applications.
