The 70% Rule for House Flipping

The 70% Rule is a quick formula used by real estate investors to determine the maximum price they should pay for an investment property. It ensures enough margin for profit and unexpected costs.

1How the 70% Rule Works

Multiply the After Repair Value by 70%, then subtract repair costs. The result is your Maximum Allowable Offer (MAO). The 30% buffer covers holding costs (2-5%), closing costs (6-10%), and profit (15%+).

MAO = (ARV × 0.70) - Repair Costs

270% Rule Example

Property ARV: $300,000. Repairs needed: $50,000. Calculation: ($300,000 × 0.70) - $50,000 = $160,000 MAO. If the seller wants $180,000, walk away—there's not enough margin.

3When to Adjust the 70%

Use 65% for: slow markets, unknown repair scope, rural areas, or first-time flippers. Use 75-80% for: hot markets where you can sell fast, properties needing minimal repairs, or when you have a buyer lined up.

Frequently Asked Questions

What is the 70% rule in real estate investing?

The 70% rule is a quick formula to determine your maximum purchase price. It states: Max Offer = (ARV × 0.70) - Repair Costs. The 30% buffer covers closing costs, holding costs, and profit.

Is the 70% rule always accurate?

The 70% rule is a starting point, not a hard rule. In competitive markets, investors may go to 75-80% and accept lower margins. In slow markets, you might need 65% to account for longer holds.

What costs does the 30% buffer cover?

The 30% margin typically covers: 3-5% buying closing costs, 3-5% selling closing costs, 5-10% holding costs (depending on hold time), and 10-15% profit margin.
