About This Underwater Mortgage Calculator
When your mortgage balance exceeds your home's market value, selling on the open market means bringing cash to the closing table — often tens of thousands of dollars to cover the shortfall plus commissions and fees. This calculator shows you exactly how much that would cost.
With a subject-to arrangement, a buyer takes over your existing mortgage payments. You avoid the negative equity gap, the selling costs, and the monthly payment burden — all without needing to come out of pocket. This calculator quantifies those savings so you can compare your options.
Understanding your true financial exposure is the first step to making an informed decision. For a deeper dive into creative financing strategies including wrap mortgages, seller financing terms, and amortization schedules, explore our full-featured GoFlexi calculator.
