Key Takeaways
- Fix and flip creates value through physical renovation, requiring significant capital and project management.
- The 70% rule (Max Price = ARV × 70% − Repairs) is the foundational deal analysis formula.
- The 30% margin must cover acquisition, financing, holding, and selling costs plus profit.
- Professional flippers use a comprehensive P&L tracking every cost category before and during projects.
Fix and flip is the most capital-intensive but potentially most profitable short-term real estate investment strategy. It involves purchasing a property below market value, renovating it to a retail-ready condition, and reselling it at full market price. This lesson introduces the fix-and-flip business model, the 70% rule that governs deal analysis, and the full profit-and-loss framework that professional flippers use to evaluate and execute projects.
What Is Fix and Flip?
Fix and flip is the practice of acquiring distressed or outdated properties at a discount, renovating them to current market standards, and reselling them to retail buyers at full market value. Unlike wholesaling (which earns a fee without renovation), fix and flip creates value through physical improvement of the property. The strategy requires significant capital (acquisition + renovation + holding costs), project management skills, contractor relationships, and accurate market analysis. Successful flippers typically target net profits of 10-15% of ARV after all costs, translating to $20,000-$50,000+ per flip depending on market and property value.
The 70% Rule
The 70% rule is the foundational formula for fix-and-flip deal analysis. It states that an investor should pay no more than 70% of the ARV minus repair costs. The formula is: Maximum Purchase Price = ARV × 70% − Repair Costs. The 30% margin (the difference between 70% and 100% of ARV) must cover all non-repair expenses: acquisition costs (2-4%), financing costs (8-12% hard money interest + 2-3 points), holding costs (insurance, taxes, utilities, maintenance during renovation and listing), selling costs (agent commissions at 5-6%, closing costs at 1-2%), and profit (10-15% target). If any of these cost categories exceeds expectations, profit erodes rapidly.
The Full Flip Profit & Loss Statement
Professional flippers analyze deals using a comprehensive P&L that accounts for every cost category. Revenue is the expected sale price (ARV). Total Project Costs include: Acquisition (purchase price + closing costs + inspection), Financing (loan origination points + interest during hold period + extension fees), Renovation (materials + labor + permits + contingency), Holding (property taxes, insurance, utilities, HOA, lawn care during hold), and Selling (agent commissions, buyer concessions, closing costs, staging, photography). Net Profit = Sale Price − Total Project Costs. The P&L should be prepared before acquisition and updated throughout the project to track actual versus projected costs.
| Cost Category | % of ARV | Dollar Amount ($300K ARV) |
|---|---|---|
| Purchase Price | 50-65% | $150,000-$195,000 |
| Renovation | 10-25% | $30,000-$75,000 |
| Acquisition Costs | 2-4% | $6,000-$12,000 |
| Financing Costs | 4-8% | $12,000-$24,000 |
| Holding Costs | 3-6% | $9,000-$18,000 |
| Selling Costs | 7-9% | $21,000-$27,000 |
| Target Profit | 10-15% | $30,000-$45,000 |

Common Mistakes to Avoid
Using the 70% rule without understanding what the 30% margin must cover
Consequence: Underestimating total costs and overestimating profit potential
Correction: The 30% covers acquisition (2-4%), financing (4-8%), holding (3-6%), selling (7-9%), and profit (10-15%).
Relying on gross profit figures without calculating net profit after all costs
Consequence: Believing a deal is profitable when financing and holding costs actually eliminate the margin
Correction: Always calculate the full P&L including all five cost categories before committing to a deal.
