What is a good ROI for house flipping?

Aim for 20–40%+ ROI on cash invested. Annualized ROI should clear 30% to justify the time, capital, and risk vs. passive alternatives.

How do I calculate the maximum offer on a flip?

Use the 70% rule: Maximum Allowable Offer = (ARV × 70%) − Repair Costs. The 30% buffer covers holding, financing, closing, agent commissions, and your profit.

What is the 70% rule in house flipping?

The 70% rule says you should never pay more than 70% of ARV minus repair costs. It's a quick sanity check used by experienced flippers — our calculator applies it automatically.

Net Profit = Sale Price − Purchase Price − Rehab Costs − Holding Costs − Buying Costs − Selling Costs

Purchase Price: What you pay (auto-checked against the 70% rule)
Rehab Costs: Renovation budget — pulled from our rehab cost estimator
Holding Costs: Loan payments, taxes, insurance, utilities during the flip
Buying Costs: Closing, inspection, appraisal, lender fees
Selling Costs: Agent commissions (typically 5–6%), closing, staging

Free, instant, and built specifically for fix-and-flip investors and real estate wholesalers.

Frequently Asked Questions

Target 10–20% net profit on the resale (ARV), or roughly $30,000–$50,000+ per flip depending on deal size and market. Sub-$25k profits leave too little margin for surprises.
