Assumable VA & FHA Mortgage Savings Calculator

VA and FHA mortgages originated since 1988 are formally assumable — a qualified buyer can take over the seller's loan at the seller's original interest rate. With rates having jumped from 3% to 7%+ in recent years, assumption can save the buyer hundreds per month and $100,000+ over the loan life. The catch: you must pay the seller's equity in cash or via a second loan.

VA vs FHA Assumption Rules

VA loans: Buyer must apply through the seller's lender, qualify on credit and income, and pay a 0.5% funding fee. If the buyer is also a veteran, they can substitute their VA entitlement so the seller fully releases liability. If the buyer is a non-veteran, the seller's entitlement remains tied to the home until full payoff. FHA loans: Full FHA underwriting required (credit score, DTI, income docs). The original borrower may remain partially liable for 5 years post-assumption unless the lender formally releases them. Both routes require lender approval, which can take 45-90 days.

When Assumption Makes Financial Sense

Assumption is most powerful when (a) the seller's rate is 2%+ below current market and (b) the seller's equity is small enough that you can pay it in cash or via a small second mortgage. If equity is large (e.g. $200K+), the cash needed may offset the rate benefit. Run the math: monthly savings × remaining years should clearly exceed any extra financing costs on the equity portion. VA assumption with entitlement substitution is the cleanest because it fully releases the seller — making it attractive to sellers and improving your negotiating position.
