redfin.comThe Full Profit Formula
Net Profit = ARV − (Purchase + Rehab + Holding + Selling)
Every one of those cost buckets matters. Investors who lose money on flips almost always underestimated one: usually rehab, sometimes holding, occasionally both.
Real Example — Northern Virginia
- ARV: $420,000
- Purchase price: $225,000
- Buying closing costs: $5,500
- Rehab: $65,000
- Holding costs (7 months): $21,000
- Selling costs (5.5% + closing): $27,000
- Net profit: $76,500
- ROI: 26%
