You have decided to develop. Here are the tools you need next.
The Property Prequel suite helps you decide whether to develop. These tools are for the moment after that decision. A free feasibility calculator to quickly check any deal, and an expert video review of your site or plans before you commit another dollar.
Two tools for two different moments
Both tools on this page are for people who have already decided to develop. If you are still working out whether development is right for you, the Decision Tools are the better starting point.

The Development Site Review
A second pair of experienced eyes, before you commit.
Before you spend more money on a development site or plans, get 30 years of property development experience looking over your shoulder. A private, asynchronous video review of your site or draft plans, delivered to your inbox within 72 business hours.
Most development mistakes are visible before you commit if you know what to look for. A council request on a tight access arrangement can stall a project for weeks. An optimistic feasibility assumption can quietly erode your margin.
"These things are almost always visible early. That is what this review gives you."
A recorded walkthrough of your site or plans, sent to your inbox.
A structured list of the risks identified, ranked by impact.
The exact questions to put to your architect, planner and builder.
Delivered within 72 business hours of you submitting your intake.
Four steps from payment to your inbox
The whole process is asynchronous. No scheduling, no meetings, no waiting for a consultant's diary.

Common questions
Is there a free property development feasibility calculator?
Yes, at propertyfeasibilitycalculator.com. Free, no email, returns gross margin, ROI and cost-to-GRV on any deal in under 2 minutes. Works for any market.
What does a property feasibility calculator tell you?
Three key metrics: gross margin percentage, return on investment, and cost-to-GRV ratio. These tell you whether a deal is worth looking at more closely before spending time or money on a full feasibility study.
What is the difference between a quick check feasibility and a full feasibility study?
A quick check tells you whether a deal has the right basic shape. A full study goes much deeper with cost breakdowns, finance costs, DA timelines, and cash flow modelling. Run the quick check first, commission the full study once you know a deal is worth pursuing.
Who is The Development Site Review for?
People who have already decided to develop and have a specific site or draft plans they want experienced eyes on before committing further time or money.
How is The Development Site Review different from hiring a consultant?
It is $249, asynchronous, and delivered within 72 business hours with no formal brief and no meeting. It is a practical second opinion to help you ask better questions of the consultants you are already working with.
Are these tools suitable for someone who has not developed before?
Yes. The calculator helps you understand the financial shape of a deal. The Site Review helps you identify what you do not know. If you are still deciding whether to develop at all, start with the Decision Tools.
Check the numbers. Get the expert eyes. Move forward with confidence.
Both tools are available right now. The calculator is free. The Site Review is $249 and delivered within 72 business hours.
