What Is the 70% Rule?

The 70% rule is the foundational formula for fix-and-flip investing. It tells you the maximum price you should pay for a property to ensure a profitable flip after all costs.

Max Purchase Price = (ARV × 70%) − Renovation Costs

Example: ARV $250,000 × 70% = $175,000 − $40,000 rehab = $135,000 max price

The remaining 30% covers your profit, hard money loan interest, closing costs (buying and selling), agent commissions, holding costs, and unexpected expenses.

Use the 65% rule if you're a beginner or in a slow market. Use 75% only if you have very accurate renovation estimates and a fast-selling market.
