The Property Viability module, explained
What it costs to build, what it can sell for, and whether the maths actually works.
The Property Viability module estimates whether a specific development, a set of units on a specific plot in a specific Nigerian location, is financially viable. It works across four tabs: Build Cost, Sale Price, TDC Model, and Feasibility Summary. On a WaVES subscription, it's typically run after the Compliance module has cleared, before Risk Assessment or Funding Gap scoring begins.
Before a deal can be scored for risk or structured for funding, there needs to be a project worth doing at all. The Property Viability module answers that question.
The four tabs
- Build Cost: WaVES suggests a construction rate per square metre based on location, build standard, and building category, which can be overridden with a quantity surveyor's figure. Land cost is entered separately. The full Total Development Cost is calculated from here, including professional fees, statutory costs, external works, contingency, funding cost, and marketing.
- Sale Price (NPVI): estimates achievable sale price per square metre using the Neighbourhood Price Value Index and a TDC-multiple approach, blended by a slider. Can be overridden with comparable sales data.
- TDC Model: stress-tests the sale price against four market-strength scenarios; Weak, Stable, Strong, and Prime luxury, showing conservative, mid, and optimistic implied prices per square metre.
- Feasibility Summary: pulls everything into profit, ROI, margin, TDC multiple, rental yield, break-even period, and the land and construction cost share of total spend.
What it connects to
The module's net cost and adjusted revenue outputs feed directly into the overall WaVES verdict, so they don't need to be re-entered elsewhere.

What does the Property Viability module actually calculate?
Total Development Cost against achievable sale price for a given Nigerian location, build standard, and project size, returning profit, ROI, margin, TDC multiple, and rental yield.
Can I use my own construction rate instead of WaVES' suggestion?
Yes. The suggested rate can be overridden manually if you have a quantity surveyor's figure. Overriding disables the auto-suggestion until you reset it.
