The NDV vs replacement-cost gap is a key diagnostic metric in property development finance UK, representing the difference between a project’s Net Development Value (NDV) and the cost of replacing or replicating the property. NDV reflects the anticipated sale value of a completed development minus all development costs, while replacement cost accounts for current construction, materials, and labour expenses. A positive gap indicates potential profit and project feasibility, whereas a negative gap signals underfunding or overvaluation risks. This metric assists UK property developers and industry professionals in making informed investment decisions and evaluating funding requirements across residual and replacement-cost analyses.


This sits beneath Replacement-Cost & Residual Diagnostics, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Land Residual Stability Index, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, NDV vs Replacement-Cost Gap is most commonly encountered in connection with Equal Share of Profits and Losses within the property development capital stack.
