Expected resale price$260,000
Purchase plus rehab$190,000

Selling costs at 8%$20,800
Estimated net profit$32,000
House Flip Calculator FAQs
Is net profit more important than ROI?
Both matter. Net profit tells you the dollar payoff, while ROI shows whether that payoff is worth the capital, risk, and time tied up in the project.
How should I estimate holding time?
Use your real timeline for inspection, permits, rehab, listing, buyer financing, and closing. Then add a buffer because time is usually where flip math gets squeezed.
What is a good flip margin?
There is no single safe margin. The needed spread depends on market speed, repair risk, financing cost, resale certainty, and your minimum return target.
