The 70% rule is a fix-and-flip guideline: pay no more than 70% of a property's after repair value (ARV) minus the cost of repairs. It leaves room for profit, holding and selling costs.
The formula
Maximum allowable offer = (ARV × 0.70) - estimated repair costs.
The remaining 30% of ARV is meant to cover closing costs on purchase and sale, agent commissions, financing and holding costs, and profit.
When to adjust it
It's a screening rule, not a law. In high-priced markets, investors may go to 75% or 80% because the dollar margin is larger. On low-priced homes, risky areas or projects with long timelines, 65% or less may be safer. Always follow up with a full budget for the specific deal.
Using it on foreclosures
For a foreclosure auction, the rule helps set a maximum bid, but you must also subtract surviving liens, back taxes, eviction or cash for keys costs, and a reserve for repairs you can't see without interior access. For REO homes, you can inspect, so repair estimates are firmer.
The formula
- ARV
- After repair value
Setting a maximum offer
A house has an ARV of $250,000 and needs $40,000 in repairs. Maximum offer = $250,000 × 0.70 - $40,000 = $175,000 - $40,000 = $135,000. If the seller wants $150,000, the deal doesn't meet the rule, and the investor either negotiates or passes.
