Did You Know?
The 70% Rule leaves ~30% for profit, holding, financing, and closing.
Hard money lenders typically fund in 5-10 days vs 30-45 for conventional.
Average flip timeline is 4-6 months from purchase to sale.
Rehab overruns of 15-25% are commonโalways add contingency.
Selling costs (agent commission) often run 6-8% of ARV.
Cash deals avoid interest but tie up capital; ROI can still be strong.
How Does the 70% Rule Work?
1. Maximum Purchase Price
Max Purchase = (ARV ร 0.70) โ Rehab. This reserves 30% for profit, holding, financing, and closing.
2. Why 70%?
The remaining 30% covers your profit margin (target 10-15%), holding costs, financing, and both sides of closing. Paying more than 70% leaves little buffer for surprises.
3. When to Adjust
In hot markets, some flippers use 65% for more cushion. In distressed areas, 75% may work if you can execute quickly and control costs.
Expert Tips
Get 3 Bids
Always get at least 3 contractor bids for rehab. Scope creep is the #1 profit killer.
Short Hold
Every extra month adds holding costs. Plan for 4 months; budget for 6.
ARV Conservatively
Use comparable sales, not list prices. Subtract 5% for market risk.
Know Your Exit
Have a backup plan: rent, wholesale, or partner if the flip doesn't sell.
