House flipping investors need accurate calculations to make profitable decisions.
Key Real Estate Investment Calculators

- Purchase Price = (After Repair Value × 0.70) – Repair Costs
- Example: For a home worth $200,000 after repairs requiring $30,000 in renovations:
($200,000 × 0.70) – $30,000 = $110,000 maximum purchase price

FAQs
- What are the essential calculators needed for house flipping investment analysis?
The essential calculators include After Repair Value (ARV) calculator, 70% Rule calculator, Repair Cost estimator, Holding Costs calculator, and Return on Investment (ROI) calculator. These tools help investors make informed decisions about potential flip properties. - How does the 70% Rule calculator work in house flipping?
The 70% Rule calculator determines the maximum purchase price for a flip property by multiplying the ARV by 70% and subtracting repair costs. For example, if ARV is $200,000 and repairs are $30,000, maximum purchase price would be: ($200,000 × 0.70) – $30,000 = $110,000. - What costs should be included in a house flip holding costs calculator?
Holding costs calculator should include mortgage payments, property taxes, insurance, utilities, HOA fees, and loan interest for the estimated flip duration. These costs typically account for 2-3% of the purchase price for every six months. - How do you calculate After Repair Value (ARV) accurately?
ARV is calculated by analyzing comparable properties (comps) that have sold within the last 3-6 months, within 1 mile radius, and with similar characteristics (size, bedrooms, bathrooms). At least 3-5 comparable sales should be used for accuracy. - What should a comprehensive repair cost calculator include?
A repair cost calculator should include materials, labor, permits, structural repairs, cosmetic updates, HVAC, plumbing, electrical work, roofing, flooring, and a 10-20% contingency buffer for unexpected issues. - How do you calculate potential profit margin in house flipping?
Profit margin is calculated by subtracting all costs (purchase price, repairs, holding costs, selling costs) from the ARV. Industry standard suggests aiming for a minimum 20% profit margin on the total investment. - What financing costs should be included in flip investment calculators?
Financing calculators should include loan interest rates, points, origination fees, closing costs, private lender fees, and potential refinancing costs. Hard money loans typically range from 10-15% interest plus 2-4 points. - How do you calculate selling costs in a house flip?
Selling costs calculator should include real estate commission (5-6%), closing costs (1-3%), transfer taxes, title insurance, escrow fees, and any buyer concessions. Total selling costs typically range from 8-10% of the sale price. - What’s the formula for calculating Return on Investment (ROI) in house flipping?
ROI is calculated by dividing net profit by total investment (including purchase price, repairs, and all costs) and multiplying by 100. For example: ($40,000 profit ÷ $200,000 total investment) × 100 = 20% ROI. - How do you calculate maximum allowable offer (MAO) for a flip property?
MAO is calculated using the formula: (ARV × 0.70) – Repair Costs = MAO. This ensures you stay within the 70% rule while accounting for necessary repairs and desired profit margin.
