70% Rule Check
Max purchase price (ARV × 70% − rehab): $142,500
Fail — your purchase price exceeds the 70% rule
Break-even ARV: $227,174 — the property needs to sell for at least this much to avoid a loss. Your ARV of $275,000 gives you $47,826 of margin (17.4%).
Researching ARV for a flip?
Search any address to see comparable sales and rental data that can help you estimate after-repair value.
A flip's profit equation is: Profit = ARV − Purchase − Rehab − Holding Costs − Financing Costs − Selling Costs. The two numbers that make or break a flip are the ARV and the rehab estimate. Underestimate rehab by $15,000 or overestimate ARV by 5% and a $50,000 profit becomes a loss.
If you are financing the flip with hard money, those costs add up fast. A $135,000 hard money loan at 12% interest with 2 points costs over $10,000 in just 6 months. This calculator includes financing so you see the true profit, not the simplified version that ignores the cost of capital.
The 70% rule says: Max Purchase = ARV × 70% − Rehab. It is conservative by design, leaving room for profit, holding costs, selling costs, and unexpected overruns. In competitive markets, some flippers push to 75% or 80%, but that leaves much less margin for error.
