What this model does

Residential feasibility, end to end.

Replace the residential feasibility spreadsheet. Capture the scheme, the AU cost stack and the settlement profile, and return profit on cost, IRR, peak debt and peak equity on every input change.

Calculation flow05 steps
  1. 01

    Site and scheme

    Lot, zoning, GFA, unit mix and car parks captured as scheme inputs.

  2. 02

    Cost stack

    Land, build by component, statutory and soft costs, finance assembled by line.

  3. 03

    Revenue

    Per-unit pricing, settlement profile, agent fee and GST treatment applied.

  4. 04

    Cashflow

    Equity-first drawdown, S-curve build, tail-loaded settlement waterfall.

  5. 05

    Returns

    Profit on cost, equity IRR, peak debt and peak equity fall out.

Schema

Engine logic

Two engines. Scenarios and cashflow.

The two pieces that separate the residential feasibility from a spreadsheet. Scenarios that share one project, and a monthly cashflow wired to every input.

Scenarios01 / 02

Multiple scenarios, one project

Switchable in a click. No copied files.

  1. 01

    One project carries multiple scenarios, switchable in a click.

  2. 02

    Each scenario keeps its own pricing, build rate, mix and finance assumptions.

  3. 03

    Compare base, downside and stretch on profit on cost and equity IRR side by side.

  4. 04

    No file duplication, no formula drift between cases.

Cashflow02 / 02

Monthly cashflow, fully connected

Every input touches the schedule.

  1. 01

    Monthly cashflow connected to every input, with annual aggregation alongside.

  2. 02

    Equity-first drawdown, then senior debt against approved claims.

  3. 03

    S-curve construction default with a manual override per project.

  4. 04

    Settlement waterfall tail-loaded across multiple months, with deposits modelled.

Excel replacement

Where the workbook quietly fails.

Every row is a recurring failure mode of the residential feasibility spreadsheet, and how the model handles it once.

Use and verify

What it decides. What to check first.

The decisions the residential feasibility is built to support, alongside the things to verify before you trust it on a live deal.

What it decidesUse cases
  1. 01

    Bid the site or walk

    Get to profit on cost, IRR and peak debt before the off-market deal moves on.

  2. 02

    Stretch the scheme

    Add a level. Lift the mix. See whether the deal still works at the same finance terms.

  3. 03

    Price the equity raise

    Show capital partners a peak equity number that holds up to scrutiny.

  4. 04

    Pressure-test the build rate

    Move $/m² up or down by component and watch margin, not just total cost.

Pre-flight checklist05 checks

  • AU cost stack: GST on revenue, Section 7.11 and authority fees handled explicitly.

  • Construction by component, not a single $/m² rate across the whole project.

  • Settlement waterfall tail-loaded, not a single completion month.

  • Scenarios switchable in-project, with no copied files or new spreadsheets.

  • Exports ready for IC and capital partners (PDF and CSV).

Questions

Residential feasibility, answered.

How Popurise handles the residential feasibility.

Does the model handle BTS apartments?

Yes. Build-to-sell apartments are the primary use case. Townhouses are also supported.

Does it handle mixed-use?

Yes, for residential-led mixed-use with a retail or commercial podium. Pure commercial is not the focus.

Can I run more than one scenario per project?

Yes. Each project carries its own scenario set. Switch between base, downside and stretch without copying files.

Is the cashflow monthly?

Monthly, with annual aggregation alongside for IC-friendly reading.

Does it produce a branded report?

Yes. PDF and CSV export are built in, ready to share with capital partners.
