House Flip Profitability Analysis

Flipping houses requires careful analysis of all costs to ensure profitability. Many new flippers underestimate holding costs and selling costs.

Profit Formula

Net Profit = ARV - Purchase Price - Rehab - Closing Costs (buy & sell) - Holding Costs - Commission

Cost Categories

  • Acquisition: Purchase price + closing costs + inspection
  • Rehabilitation: Materials, labor, permits, contingency
  • Holding costs: Loan payments, insurance, taxes, utilities, HOA
  • Selling costs: Agent commission, closing costs, staging

    • Rules of Thumb

  • 70% Rule: Maximum purchase = ARV x 70% - Rehab costs
  • Target minimum profit of $25,000-$30,000 per flip
  • Budget 10-20% contingency on rehab costs
  • Expect 4-8 months total timeline

    Buy at $200,000, rehab $50,000, sell at ARV $320,000. 6-month hold at $2,000/month. Buy closing $5,000, sell at 5% commission + $3,000.

    1. Total holding costs: $2,000 x 6 = $12,000
    2. Total investment: $200,000 + $50,000 + $5,000 + $12,000 = $267,000
    3. Selling commission: $320,000 x 5% = $16,000
    4. Total selling costs: $16,000 + $3,000 = $19,000
    5. Total cost: $267,000 + $19,000 = $286,000
    6. Net profit: $320,000 - $286,000 = $34,000
    7. ROI: $34,000 / $267,000 = 12.7%
    8. Profit margin: $34,000 / $320,000 = 10.6% of ARV
