Mortgage Assumption Calculator 2026: Save $268K vs New Loan

Q: What is the mortgage assumption fee?

Assumption fees by loan type: FHA = $900 (highest), VA = $300 (lowest), USDA = $500-1,000, Conventional = 1% of balance (rare). Total closing costs: $2K-5K (assumption) vs $8K-12K (new loan). Savings: $6K-10K on closing costs alone. Fee is paid at closing to lender.

Q: Can I assume a mortgage with bad credit?

Yes, but harder. Minimum credit scores: FHA assumption = 580, VA assumption = 620, USDA assumption = 640. Lower score = higher scrutiny. Compensating factors help: (1) Large down payment (25%+), (2) Low DTI (<35%), (3) Significant reserves (6+ months), (4) Stable employment (5+ years). Some sellers allow 'subject to' (no qualification) but risky.

Q: How long does mortgage assumption take?

Assumption timeline: 45-60 days average. Process: Submit application (Day 1), Credit/income review (Days 1-10), Lender approval (Days 10-30), Assumption agreement prepared (Days 30-40), Closing (Days 45-60). Faster than new loan (60-75 days) but slower than cash (30 days). Plan for 60 days minimum.

Q: What happens to the seller after assumption?

After assumption: (1) Seller released from liability (no longer responsible for loan), (2) Buyer assumes all responsibility, (3) Seller receives equity (price - loan balance), (4) Loan stays in seller's credit history (positive if paid on time). VA loans: Seller's VA entitlement restored after assumption (can get another VA loan).
