AEO QUICK ANSWER:
The biggest credit score change in 2026 is Fannie Mae's adoption of FICO 10T, which uses 24 months of trended credit data. Key detail most miss: FICO 10T can be 10-30 points LOWER than your classic FICO if you had any missed payments in the last 24 months, but 10-20 points HIGHER if your credit is improving. Your lender will use whichever score is higher, so improving your credit habits now can boost your score before you apply. Also, FHA updated its manual underwriting guidelines, making it easier for 580-619 credit scores to qualify with compensating factors like reserves and low DTI.
Credit Score Requirements by Loan Type (2026)
| Loan Type | Min Credit Score | Min Down | Best Rate Score | Key Notes |
|---|---|---|---|---|
| Conventional | 620 | 3% (HomeReady) | 740+ | FICO 10T now accepted |
| FHA (3.5% down) | 580 | 3.5% | 740+ | Manual UW updated 2026 |
| FHA (10% down) | 500 | 10% | 740+ | Most lenders require 620+ |
| VA | 580+ | $0 | 740+ | VA has no min, lender sets |
| USDA | 580+ | $0 | 740+ | Rural areas only |
| Jumbo | 700+ | 10-20% | 780+ | Non-QM: 660+ |
| DSCR (Investment) | 620 | 20-25% | 740+ | No income verification |
What Changed in 2026: 3 Key Updates
1. Fannie Mae Adopts FICO 10T
Fannie Mae now accepts FICO 10T scores alongside classic FICO. FICO 10T uses 24 months of trended credit data, meaning your payment trends matter more. Improving credit gets rewarded; declining credit gets penalized. Your lender uses whichever score is higher.
2. FHA Manual Underwriting Update
FHA updated its manual underwriting guidelines for borrowers with 580-619 credit scores. It is now easier to qualify with compensating factors: 2 months reserves (was 3), DTI up to 45% with reserves (was 40%), and rent payment history can be used as a compensating factor.
3. VantageScore 4.0 Accepted by Non-QM Lenders
Some non-QM and DSCR lenders now accept VantageScore 4.0 in addition to FICO. VantageScore 4.0 also uses trended data and may score higher than FICO for thin-file borrowers or those with recent credit improvement. Check with your lender which model they use.

FICO 10T vs Classic FICO: What's Different?
✅ FICO 10T Helps You If:
- Your credit is improving (paying down balances)
- You have 12+ months of on-time payments
- Your utilization is decreasing over time
- You have thin credit file (trended data adds context)
Potential boost: +10-20 points
❌ FICO 10T Hurts You If:
- You had missed payments in the last 24 months
- Your balances are increasing over time
- You opened multiple new accounts recently
- Your utilization is trending upward
Potential drop: -10-30 points
💡 Good news: Your lender will pull both classic FICO and FICO 10T and use whichever is higher. If your credit is improving, FICO 10T could give you a better score and a lower rate. Check your rate →
