Why Popurise
Stop rebuilding
the model.
Development feasibility used to mean copying a previous workbook and hoping the formulas still held. Popurise gives the team one place to screen a site, model the deal and see whether it stacks up.
- 01
Screen sites faster.
Build a first-pass feasibility without starting from a blank workbook every time.
- 02
See the deal logic clearly.
Land, costs, revenue, timing, debt and return metrics live in one structured workflow.
- 03
Change assumptions without chaos.
Test the moving parts of the deal without chasing broken formulas through another file.
- 04
Move from quick check to full model.
Start with a simple screen, then build a saved feasibility when the site deserves more work.
- 05
Compare sites like for like.
Keep every project in one workspace instead of a folder of copied spreadsheets.
- 06
Built for Australian projects.
Acquisition costs, GST on sales, finance and timing modelled the way local development runs.
The old way vs Popurise
Every new deal starts as another spreadsheet.
A development feasibility built in Excel is fine on day one and fragile by version five. Popurise gives your team one place to screen the deal, compare the cases and see the numbers that decide what moves forward.

What it is
What property development feasibility software does.
It replaces the spreadsheet you would otherwise build for every deal — turning a site's assumptions into the numbers you decide on.
In plain English
Property development feasibility software models whether a development site stacks up financially. It turns assumptions about land, acquisition costs, construction, professional fees, contingency, finance, timing and sales revenue into development profit, development margin, profit on cost and IRR. Popurise is property development feasibility software for Australian teams — it replaces fragile spreadsheets so you can screen sites, compare scenarios and share results without rebuilding a model for every deal.

- Development margin
- Profit on cost
- Equity IRR
- Monthly project cash flow
- Peak debt and peak equity
- Scenario comparison
- Saved, reusable projects
What you can model
Everything a development deal actually needs.
Popurise models the full picture — costs, finance, timing, revenue and returns — not just a single headline number.
Construction and project costs
Construction cost, professional fees, contingency and other project costs in a structured cost build-up.
Timing and staging
Project timing across planning, construction and settlement, so costs and revenue land in the right months.
Debt and finance
A debt facility with interest and drawdown, surfacing peak debt and peak equity across the program.
Revenue and cash flow
Sales revenue and gross realisation (GRV), fed into a monthly project cash flow for the whole project.
Returns, scenarios and saved projects
Development profit, development margin, profit on cost and equity IRR — compared across scenarios and saved in one workspace.
The spreadsheet problem
Why feasibility spreadsheets break down.
Excel is a fine place to start and a hard place to stay. As a development deal moves, the spreadsheet is usually the last thing to keep up.
01
Assumptions get buried
Key inputs end up scattered across tabs and cells, so no one can see what actually drives the result.
02
Formulas get hardcoded
A number gets typed over a formula during a late night, and the model quietly stops calculating.
03
Timing changes everything
Shift the program by a few months and finance, drawdown and cash flow all move — the spreadsheet rarely keeps up.
04
Debt and interest are hard to audit
Interest on a moving debt balance is fiddly to model and even harder for someone else to check.
05
Comparing sites gets messy
Every new site starts as another copied file, so a like-for-like comparison is slow and error-prone.
06
Version control breaks down
“final_v7_REALfinal.xlsx” — and no one is sure which file holds the numbers the deal was approved on.
07
Sharing is clunky
Sending a workbook to a partner or investment committee means emailing yet another version and hoping it is read right.
08
Quick screening becomes slow
When every deal begins from another spreadsheet, quick screening stops being quick.
Which tool, when
Calculator, spreadsheet or feasibility software.
Each has a job. The trick is knowing which one the deal in front of you actually needs.
A quick calculator
Useful when you are screening one simple deal or checking a single number — a profit, a margin or a supportable land value.
An Excel spreadsheet
Flexible, but turns fragile once assumptions, debt, timing and scenarios start changing and the file gets passed around.
Feasibility software
Earns its place when you need repeatable modelling — saved projects, timing, debt, cash flow, scenario comparison and shareable outputs.

Set the program across planning, construction and settlement so costs and revenue land in the right months.
- 03
Check costs and revenue
See the full cost build-up and gross realisation update as you change assumptions.
- 04
Review the output metrics
Read development profit, margin, profit on cost and equity IRR up front, with peak debt and peak equity.
- 05
Decide the next step
Keep screening, park the site, or build a full feasibility with scenarios and saved projects.
Compare
Compare a quick result with a full Popurise feasibility.
You have seen the quick screen. Open the same site in Popurise to add timing, monthly cash flow, debt and scenarios — then decide with confidence.
Replace the spreadsheet
A property development feasibility spreadsheet alternative.
Searching for a property development feasibility template, a development feasibility Excel model or a real estate development model in Excel usually ends the same way — another fragile financial model to maintain. Here is what changes when the model lives in software.
The spreadsheet
Another fragile model to maintain
- Version control across files and inboxes
- Hidden assumptions buried in cells
- Hardcoded formulas that silently break
- Timing and debt complexity by hand
- Poor side-by-side scenario comparison
- Difficult, version-heavy sharing
- Slow to reuse across the next site
Popurise
Screen the deal, not the file
- One live project, not a folder of copies
- Assumptions stay visible and editable
- Structured inputs with a clear cost build-up
- Timing, debt and monthly cash flow built in
- Scenarios compared side by side
- Share a live link or a clean report

Questions
Property development feasibility software, answered.
What is property development feasibility software?
Property development feasibility software is a tool that models whether a development site is financially viable. It takes assumptions about land, acquisition costs, construction, fees, contingency, finance, timing and revenue, and returns development profit, development margin, profit on cost, cash flow and IRR — so you can decide whether a site is worth pursuing.
Who is Popurise for?
Popurise is built for Australian residential developers, acquisition managers, property analysts, development managers, property consultants and smaller developers who currently screen sites and assess deals in Excel, feasibility templates or legacy feasibility software.
Is Popurise a replacement for Excel?
For development feasibility, yes. Popurise gives you structured inputs, project timing, debt and interest, monthly cash flow, scenario comparison and shareable outputs without hand-building and maintaining a spreadsheet. You can still export to Excel when you need to hand numbers to someone who works there.
What is the difference between a feasibility calculator and feasibility software?
A feasibility calculator answers one question quickly — a single profit, margin or land value for one set of inputs. Feasibility software is built for repeatable modelling: saved projects, project timing, debt and cash flow, scenario comparison and outputs you can share. Use a calculator to screen; use software when a site deserves a proper look.
Does Popurise work for Australian residential development?
Yes. Popurise is designed for Australian residential development — apartments, townhouses and medium-density sites — with acquisition costs, GST on sales, construction, finance and timing modelled the way Australian projects actually run.
Can I model debt, timing and cash flow?
Yes. Popurise models project timing and staging, a debt facility with interest and drawdown, and a monthly project cash flow, so you can see peak debt, peak equity and how returns move as the program changes.
Can I compare multiple development sites?
Yes. You can build scenarios within a project and keep every project saved in one workspace, so comparing sites and assumptions is a like-for-like comparison rather than a folder full of copied spreadsheets.
Can Popurise help with residual land value?
Yes. By working back from gross realisation, costs, finance and a target return, Popurise helps you test what a site can support — the residual land value logic behind a land bid — and stress-test it across scenarios.
Is this financial advice?
No. Popurise and the preview on this page are modelling tools for testing development assumptions. Outputs are illustrative and depend entirely on the inputs you provide. They are not financial, investment or valuation advice.
