What is flip ROI?
Flip ROI is the return on investment you earn from a property renovation. The formula is simple: (Sale price − total costs) ÷ total costs × 100. What flippers usually under-count is the total costs half of that equation — stamp duty, holding cost, selling cost and tax all eat into the headline gain.
What counts as a total cost?
Purchase price, stamp duty, acquisition costs (legal, conveyancing, building inspection), renovation cost, holding costs across the entire hold (interest, rates, insurance, utilities), selling costs (agent commission, marketing, legal), and tax on the profit. If you skip any one of those, your ROI inflates.
How does FlipPro do this for you?
The FlipPro app pulls comps to estimate your sale price, runs stamp duty against the right state bracket, calculates holding cost from your loan and timeline, and applies the 50% CGT discount where the hold qualifies. You get the same answer in under a minute — on a real listing — instead of typing twelve numbers into a spreadsheet.
