The same framework we use to assess every site we look at. Sign up for a free account and run as many scenarios as you like.
Most feasibility tools are designed to make a deal look better than it is. They use optimistic build costs, ignore holding costs, and assume best-case sale prices. Ours doesn't.
We built this calculator to give a quick, honest read on whether a development site stacks up financially. It uses the inputs that actually matter, applies conservative assumptions where there's uncertainty, and tells you clearly where the project lands: proceed, borderline, or walk away.
There's no magic here. It's arithmetic applied carefully. The same arithmetic every experienced developer runs before committing to anything.
Plug in the land price, expected build cost, and likely sale price to see if the numbers actually work before you get attached to the idea.
Run a hypothetical to see how changing one variable (land cost, build cost, end value) and how it changes the margin. It's the fastest way to build intuition for the numbers.
Run the calculator on best case, worst case, and most likely case. If it only works in the best case scenario, that's important information before you make an offer.
The calculator applies cost assumptions based on typical Sunshine Coast development conditions: professional fees, holding costs, contingency, and sales costs. You can adjust inputs to reflect your specific situation. If a deal only works when you strip out contingency and assume zero holding costs, it probably doesn't work.

Subdivision and unit development: the two most common small-scale development types on the Sunshine Coast, and the ones we have the most direct experience with.
They're designed to be conservative, not aspirational. Professional fees, holding costs, contingency, and selling costs are applied based on our own project experience. You can adjust inputs to reflect your specific situation.
Use it as a starting point, not a final answer. A feasibility calculator gives you a directional read. Follow it with detailed analysis and a conversation with a town planner, QS, and solicitor before making any offer.
