See what taking over a seller's existing FHA, VA, or USDA loan would actually save compared to a new mortgage at today's rate — including the cost of covering the equity gap.
The assumed-loan payment is calculated using the seller's actual rate and remaining balance over whatever years are left on their original term — not a fresh 30 years. That's the whole advantage: you inherit both their lower rate and their head start on the amortization schedule.
The new-loan comparison shows what it would cost to finance the same amount at today's market rate instead, so you can see the real dollar gap side by side. If you enter a sale price and cash available, the calculator also estimates the "equity gap" — the part of the price not covered by the assumable balance — and what financing that gap would add to your monthly payment.
