Methodology
Calculation basis
Residual land value is calculated as gross development value less hard cost, soft cost, finance and holding cost, selling cost, contingency, and required developer profit.
This runner establishes the common ValuTax tool pattern: controlled assumptions, live diagnostics, sensitivity outputs, professional interpretation, member save/export hooks, and clear limitation language.
