What This Calculator Estimates
Real estate flipping analysis estimates potential profit by comparing purchase price plus renovation and holding costs against expected resale value, helping investors assess whether a specific property flip makes financial sense before committing capital. This calculator estimates flip profit using the purchase price, renovation costs, holding costs, and expected sale price you provide.
Formula / Method Used
Selling Costs = ARV × (Selling Cost % ÷ 100). Total Costs = Purchase Price + Renovation + Holding Costs + Selling Costs. Profit = ARV − Total Costs.
Worked Example
A $200,000 purchase with $40,000 renovation, $8,000 holding costs, and a $310,000 expected resale at 8% selling costs ($24,800) leaves an estimated profit of $37,200.
How to Interpret the Result
Compare estimated profit against your time investment and risk tolerance. Many flippers target at least 10-20% of ARV as profit margin to account for unexpected costs and market shifts.
Common Mistakes
- Underestimating renovation costs or overlooking permit fees.
- Ignoring holding costs on a longer-than-expected timeline.
- Using an overly optimistic ARV without solid comparable sales.
- Forgetting financing costs like loan points or interest.

Tips for a More Accurate Estimate
- Get contractor quotes for renovation costs rather than relying on rough estimates.
- Include all holding and selling costs, not just purchase price and renovation, in your analysis.
- Research comparable sales carefully to get a realistic after-repair value estimate.
- Build in a margin of safety, since flip projects commonly face unexpected costs or delays.
- Consider holding time carefully, since longer timelines increase carrying costs without added value.
Frequently Asked Questions
What costs should be included in a flip analysis beyond purchase price?
Renovation costs, holding costs (mortgage interest, taxes, insurance during the renovation period), selling costs (agent commissions, closing costs), and sometimes financing costs should all be factored in beyond just the purchase price.
How accurate do renovation cost estimates need to be for flip analysis?
Very accurate, ideally based on contractor quotes rather than rough guesses, since renovation costs are often where flip projects go over budget and erode expected profit margins.
What is the 70% rule sometimes referenced in house flipping?
It's a rule of thumb suggesting investors shouldn't pay more than 70% of the after-repair value minus renovation costs, providing a margin of safety for unexpected costs and ensuring adequate profit potential.
How does holding time affect flip profitability?
Longer holding periods increase carrying costs (mortgage interest, taxes, insurance, utilities) without adding to resale value, so faster renovation and sale timelines generally improve overall profitability.
Should I get a professional appraisal or comparable sales analysis before flipping?
Yes, an accurate estimate of after-repair value from comparable sales or professional appraisal is critical, since overestimating resale value is a common way flip projects underperform expectations.
