Credit Score for Mortgage: What You Actually Need
Minimum requirements, which score version lenders use, and how your score translates to real dollar costs.
Getting approved for a mortgage and getting a good rate are two different things.
You can technically qualify with a 580 credit score. But the rate you get at 580 versus 760 will cost you tens of thousands of dollars over the life of the loan.
Here's exactly what lenders look at, the minimum requirements by loan type, and how to optimize your score before applying.
Minimum Credit Score by Loan Type
| Loan Type | Minimum Score | Down Payment | Notes |
|---|---|---|---|
| FHA | 580 | 3.5% | 500-579 requires 10% down |
| Conventional | 620 | 3-20% | PMI required under 20% |
| VA | None (VA) | 0% | Lenders typically want 620+ |
| USDA | 640 | 0% | Rural areas only |
| Jumbo | 700-720+ | 10-20% | Stricter requirements |
Which Score Do Mortgage Lenders Use?
⚠️ Critical: Not the Score You See Online
Mortgage lenders use older FICO versions: FICO Score 2 (Experian), FICO Score 5 (Equifax), and FICO Score 4 (TransUnion). These differ from the FICO 8 or VantageScore you see on Credit Karma or most free apps — often by 20-50+ points.
Lenders pull all three bureau scores and use the middle score. If your scores are 650, 680, and 710, they use 680.
For joint applications, lenders use the lower middle score between both applicants.
The Cost of Each Score Tier
On a $350,000 mortgage over 30 years (2025 rates):
| FICO Score | Estimated APR | Monthly Payment | Total Interest |
|---|---|---|---|
| 760-850 | 7.24% | $2,385 | $508,000 |
| 700-759 | 7.45% | $2,431 | $525,000 |
| 680-699 | 7.56% | $2,455 | $534,000 |
| 660-679 | 7.61% | $2,467 | $538,000 |
| 620-639 | 7.84% | $2,518 | $556,000 |
The difference: 620 vs 760 = $48,000 extra interest on the same loan.
Even jumping one tier (e.g., 680 to 700) can save $10,000+ over the loan's life.

What NOT to Do Before Applying
🚫 Mortgage Application Don'ts
- • Don't open ANY new credit accounts
- • Don't close ANY existing accounts
- • Don't make large purchases on credit
- • Don't move large sums between accounts (looks like undisclosed loans)
- • Don't co-sign for anyone
- • Don't change jobs if you can avoid it
- • Don't pay off collections without checking first (can reset dates)
The Rate Shopping Window
FICO gives you a 14-45 day window for mortgage rate shopping. All hard inquiries within this period count as a single inquiry.
Use this to your advantage: get quotes from 3-5 lenders within a 2-week period. The inquiries won't stack up against you.
Rapid Rescore: The Last-Minute Fix
If your score is just below a tier threshold during underwriting, ask your lender about a rapid rescore.
💡 How Rapid Rescore Works
- • You pay down a balance or fix an error
- • Lender pays the bureaus to update immediately (3-5 days)
- • Costs $25-50 per tradeline per bureau
- • Only lenders can initiate — you can't do it yourself
This can bump you from 679 to 685, potentially saving thousands in interest.
Collections and Mortgages: The Fannie Mae Rules
Good news: You may not need to pay off all collections to qualify.
- Medical collections — Ignored entirely by Fannie Mae automated underwriting
- Non-medical collections (principal residence) — Don't need to be paid if automated underwriting approves
- Investment properties — Collections over $250 typically must be paid
However, the underwriter may impute a monthly payment (typically 5% of balance) into your debt-to-income calculation, even if unpaid.
After Bankruptcy: When Can You Buy?
| Loan Type | Chapter 7 Wait | Chapter 13 Wait |
|---|---|---|
| FHA | 2 years from discharge | 1 year (w/ trustee approval) |
| VA | 2 years from discharge | 1 year (w/ trustee approval) |
| Conventional | 4 years from discharge | 2 years from discharge |
| USDA | 3 years from discharge | 1 year (w/ trustee approval) |
The Bottom Line
Getting approved is the first hurdle — FHA at 580, conventional at 620.
Getting a good rate is where the real money is. Every 20-point score improvement can save you thousands over the loan term.
The most important advice: start 6 months early. Optimize utilization, fix errors, and avoid any new credit activity. The prep work pays for itself many times over.
