The short answer in 2026: You can technically buy a house with a credit score as low as 500 if you’re willing to pay for it.
The real answer: If you want a mortgage that doesn’t feel like financial punishment, you need at least 700 — and ideally 740 or higher.
Here’s exactly what every major loan type requires today, what it actually costs you at different score tiers, and how much money you leave on the table by settling for “good enough.”
Minimum Credit Score Requirements by Loan Type (December 2025 – 2026 Guidelines)
Conventional Loans (Fannie Mae & Freddie Mac)
- Absolute minimum: 620
- Realistic minimum for approval without heavy scrutiny: 680
- Best pricing tier (LLPA grid): 740+
- Sweet spot in 2026: 760+ (many lenders now give their absolute lowest rate at 760–780)
FHA Loans
- 580+ with 3.5% down
- 500–579 with 10% down (yes, lenders still do these, but only a handful remain)
- Note: Most FHA lenders overlay 640+ in 2026 because of risk-based pricing
VA Loans
- No official minimum (technically 0)
- Reality: Almost every VA lender requires 620–640
- 700+ gets you the best execution and often no lender overlays
USDA Loans
- No set minimum, but lenders require 640+
- 680+ avoids manual underwriting headaches
Non-QM / Bank Statement / DSCR Loans
- 660–720 typical minimum
- Some asset-depletion and true no-FICO products exist down to no score (but at 8–12% rates)
How Much Does Your Credit Score Actually Cost You in 2026?
$450,000 purchase price, 5% down conventional loan, 30-year fixed (national averages as of Dec 2025)
| Credit Score | Interest Rate | Monthly PI Payment | Total Interest Paid Over 30 Years | Extra Cost vs 760 Score |
|---|---|---|---|---|
| 760–780+ | 5.625% | $2,462 | $470,000 | $0 |
| 740–759 | 5.750% | $2,495 | $483,000 | +$13,000 |
| 720–739 | 5.875% | $2,529 | $496,000 | +$26,000 |
| 700–719 | 6.125% | $2,596 | $520,000 | +$50,000 |
| 680–699 | 6.375% | $2,664 | $545,000 | +$75,000 |
| 660–679 | 6.750% | $2,770 | $582,000 | +$112,000 |
| 640–659 | 7.250% | $2,915 | $635,000 | +$165,000 |
| 620–639 | 7.875% | $3,105 | $700,000+ | +$230,000+ |
That’s not a typo. A 620 score versus 760+ costs the average buyer over $230,000 in extra interest on a $450k home.
Even worse: Lenders now hit lower scores with additional loan-level price adjustments (LLPAs) of 1.5–3.75% of the loan amount. That’s another $6,000–$15,000 in upfront fees or rate.
The Hidden Breakpoints That Matter Most in 2026
740 → Unlocks the best conventional pricing tier
760 → Many lenders’ internal “platinum” tier (often 0.125–0.25% better than advertised rates)
720 → Avoids the brutal 0.75–1.5% LLPA hit
700 → Still decent, but you’re leaving real money on the table
680 → Pricing starts getting ugly fast
660 → PMI becomes dramatically more expensive if putting <20% down
620 → You’re now in manual underwriting territory with limited lender options
How Long Does It Take to Boost Your Score to the Next Tier?
Realistic timelines based on current credit profiles we see daily at Hamilton Home Sales:
580 → 620: 3–8 months (pay down cards, add authorized user if needed)
620 → 680: 6–12 months
680 → 720: 9–18 months
720 → 760: 12–24 months (mostly time + perfect payment history)
Pro move in 2026: Use Experian Boost or UltraFICO to add utility, phone, and streaming payments to your file — often adds 15–40 points in 30 days.
The 2026 Reality Check
Yes, you can buy with a 620 or even a 580 if you absolutely must.
But you will pay tens of thousands more — sometimes hundreds of thousands — for the privilege.
Every single one of our buyers who waited 9–14 months to go from the 660–680 range to 740+ has thanked us later. They’re saving $250–$450 per month for the entire life of the loan.
Your credit score isn’t a badge of honor. It’s the single biggest lever you control in determining whether homeownership builds wealth or quietly drains it.
Fix it first. Buy once. Win forever.
