A web-based tool connects mortgage, property value, rental, tax, and investment assumptions into side-by-side financial scenarios. Users can compare outcomes like selling now, renting temporarily, making lump-sum principal payments, re-amortizing, refinancing, or keeping a rental property, with clear monthly cash flow and net worth projections.

High interest rates, locked-in low mortgages, affordability pressure, and slower housing markets are forcing more homeowners into complex keep-versus-sell decisions. Millions of owners need practical modeling before making irreversible property moves.
