Frequently asked questions
What does the Sunshine Coast feasibility calculator include?
Land cost, build cost, finance interest during construction, holding costs and a contingency buffer, the four numbers that decide whether a Banya, Aura or Caloundra project actually stacks up.
Is this calculator suitable for a knockdown-rebuild in Buderim or Mooloolaba?
Yes. The calculator works for any single-dwelling new build or KDR across the Sunshine Coast, Buderim, Mooloolaba, Maroochydore, Caloundra and the Aura corridor.
Does it cover construction loan progress payments?
It models total interest cost during the build window. For a full progress-payment schedule and lender comparison, book a call with Brokerly after running the numbers.
What contingency should I assume for a Sunshine Coast build right now?
Most Brokerly clients use 7.5%–10% contingency in 2026 for QLD residential builds, given lingering trade pricing volatility and weather delays.
Is this calculator the same as the Developer Feasibility Worksheet?
No. This one is for owner-builders and small dual-occ projects. For multi-lot residual land value modelling and PDF export, use the Developer Feasibility Worksheet.
