Start modellingWhat this model does
Run a clean feasibility on a duplex without an analyst. Two dwellings, subdivision and finance handled in minutes, with profit on cost, equity IRR and peak debt at the top.
Schema
The full duplex feasibility model schema. 7 input blocks feeding 8 output metrics, with the calculation engine in between.
Engine logic
The two pieces that separate the duplex feasibility from a spreadsheet. Scenarios that share one project, and a monthly cashflow wired to every input.
Switchable in a click. No copied files.
Sell-both vs hold-one as a scenario switch.
Move pricing and build rate per scenario on one project.
Each scenario keeps its own cashflow shape.
No second workbook for the hold case.
Every input touches the schedule.
Cashflow sized for two dwellings, not twenty.
Subdivision sits in the programme with its own duration and cost.
Sell-both runs two settlements; hold-one models rent in the cashflow.
Equity-first drawdown, with senior debt scaled to the build cost.
Excel replacement
Every row is a recurring failure mode of the duplex feasibility spreadsheet, and how the model handles it once.
Use and verify
The decisions the duplex feasibility is built to support, alongside the things to verify before you trust it on a live deal.
Get to profit on cost and peak debt before the contract goes unconditional.
Test sell-both vs hold-one as a scenario. See the equity outcome.
Move build rate by dwelling and watch the margin respond.
Sell on completion or stagger. See the cashflow consequence.
Questions
How Popurise handles the duplex feasibility.
No. It is sized down to two dwellings, with the rest of the framework collapsing automatically.
Yes. Set it as a scenario and the cashflow follows.
Yes. Subdivision sits in the programme with its own duration and cost.
Yes. Build rate per dwelling lets you connect the price to the build.
No spreadsheet. No setup. Open Popurise and model the deal.
