The 70% Rule Explained
The 70% rule states that an investor should pay no more than 70% of the After Repair Value (ARV) minus rehab costs. Formula: Max Offer = (ARV × 0.70) − Rehab Costs
Frequently Asked Questions
What is a good ROI for a house flip?
Most experienced flippers target a minimum 20% ROI per flip. Annualized returns above 40% are considered excellent. Risk, holding time, and market conditions all factor in.
What costs do house flippers overlook?
Common hidden costs: holding costs (every month matters), agent commissions (5–6% is significant), permit fees, unexpected structural repairs, utilities during rehab, and financing fees. Always add a 10–15% contingency buffer.
How do I reduce risk on a flip?
Buy at the right price (use the 70% rule), get accurate rehab estimates before closing, use local contractors with track records, keep a contingency fund, and have an exit strategy if the market softens.
