How It Works

A House Flip Calculator helps real estate investors estimate potential profits and necessary financing for a property renovation and resale project. It's crucial for determining if a flip is financially viable and setting a realistic budget to avoid losses.

This calculator typically uses a formula that subtracts the total project costs (purchase price, renovation expenses, holding costs, selling costs) from the estimated After Repair Value (ARV) of the property. The result is the projected gross profit, which can then be used to calculate return on investment (ROI).

Common mistakes include underestimating renovation costs, overestimating the ARV, and forgetting to account for all holding costs (taxes, insurance, utilities) during the flip period. Always build in a contingency fund (10-15% of renovation costs) for unexpected issues.

Example: Flipping a House in a Growing Neighborhood

  1. 1 Input Numbers: Purchase Price = $200,000; Renovation Budget = $50,000; Holding Costs (3 months) = $5,000; Selling Costs (8% of ARV) = $28,000; Estimated After Repair Value (ARV) = $350,000.
  2. 2 Calculation: Total Costs = $200,000 (Purchase) + $50,000 (Renovation) + $5,000 (Holding) + $28,000 (Selling) = $283,000. Projected Gross Profit = $350,000 (ARV) - $283,000 (Total Costs) = $67,000.
  3. 3 Result: The projected gross profit for this house flip is $67,000.
  4. 4 Takeaway: With a projected gross profit of $67,000, this flip appears to be a potentially profitable venture. However, further due diligence, including market analysis and detailed contractor quotes, is essential before committing to the project.

Frequently Asked Questions

What is the 70% rule in house flipping?
The 70% rule says you should pay no more than 70% of the After Repair Value (ARV) minus repair costs. For a house with a $300,000 ARV and $50,000 in repairs, the maximum purchase price should be ($300,000 x 0.70) minus $50,000 = $160,000.
How much profit should a house flip make?
Experienced flippers aim for a 15-20% return on the total investment (purchase plus rehab). On a $200,000 project, that is $30,000-$40,000 profit. After holding costs, selling costs, and taxes, net profit is often 10-15%.
How long does a house flip take?
The average house flip takes 4-6 months from purchase to sale. Renovation typically takes 2-4 months, and selling takes 1-3 months depending on the market. Faster flips reduce holding costs and improve ROI.
