The difference between a profitable flip and a money-losing disaster often comes down to one thing: accurate deal analysis before you buy. The 70% Rule is the foundation, but experienced flippers go much deeper.
The 70% Rule Explained
The 70% Rule states that you should pay no more than 70% of the After Repair Value (ARV) minus repair costs:
Maximum Offer = (ARV x 0.70) - Repair Costs
For example: if a property's ARV is $300,000 and repairs will cost $50,000: Maximum Offer = ($300,000 x 0.70) - $50,000 = $160,000
The 30% margin covers your profit, holding costs, selling costs, and unexpected expenses.
Why 70% Isn't Always Right
The 70% Rule is a starting point, not a rigid formula. Adjust based on:
- Hot markets: Some flippers work at 75-80% in competitive markets with fast appreciation
- Expensive properties: On $1M+ homes, 75-80% may still yield good dollar profit
- Cheap properties: On $100K homes, you might need 60-65% to make the deal worthwhile
- Your experience: Beginners should stick to 65-70% for safety margin
All the Costs You Must Account For

Holding Costs (Monthly)

- Contingency (15-20%)
Selling Costs (8-10% of sale price)
- Agent commissions (5-6%)
- Closing costs (1-2%)
- Staging ($2,000-5,000)
- Photography and marketing

Advanced Profit Strategies
1. Speed Is Profit
Every month you hold a property costs money. The fastest flippers:
- Have contractors lined up before closing
- Order materials before closing
- Work on multiple trades simultaneously
- Target 60-90 day renovations
2. Focus on High-ROI Improvements
Not all renovations are equal. Highest ROI improvements:
- Kitchen updates (60-80% ROI)
- Bathroom updates (50-70% ROI)
- Curb appeal (100%+ ROI)
- Fresh paint throughout (200%+ ROI)
- New flooring (70-80% ROI)
3. Don't Over-Improve
The biggest mistake new flippers make is over-renovating for the neighborhood. Your flip should be the nicest house on the block, but not a mansion surrounded by starter homes.
4. Buy the Worst House on the Best Street
Location determines ARV more than anything. A mediocre renovation in a great neighborhood will outperform a perfect renovation in a bad neighborhood.
Using the Fix & Flip Calculator
Our calculator helps you model all these costs before making an offer. Input your numbers for purchase price, rehab costs, holding period, and expected sale price to see your projected profit, ROI, and whether the deal meets the 70% Rule.
Remember: the profit is made when you BUY, not when you sell. If the numbers don't work at your maximum offer price, walk away. There will always be another deal.
