Model the cash needed to buy out a partner and the mortgage that may remain if one person keeps the home.
Change any number. The estimate updates in your browser and is not sent to Incolator.
The calculator subtracts the mortgage and your chosen sale-cost allowance from the home value, applies the share you entered, then adds that buyout and transfer costs to the existing mortgage. Cash applied reduces the modeled new loan.
The result is arithmetic, not a statement about ownership. Courts, agreements, title, debt responsibility, taxes, support, appraisal disputes, lender underwriting, and state marital-property law can change the real outcome. An 80% loan-to-value line is shown only as a planning checkpoint, not a lending promise.
Use an independent appraisal, current payoff statement, actual lender quote, and advice from qualified local professionals before signing anything.
