How to Analyze a Fix & Flip Deal
The most common mistake new flippers make is focusing only on purchase price and ARV while ignoring the costs in between. A profitable flip requires accurate estimates across four cost categories:
- Acquisition Costs — Purchase price plus buyer closing costs (title insurance, inspection, appraisal, loan origination fees). Typically 1-3% of the purchase price.
- Rehab Costs — The full renovation budget including materials, labor, permits, and a 10-20% contingency buffer for surprises. Walk the property with a contractor before making an offer.
- Holding Costs — Every month you own the property costs money: loan interest (or opportunity cost if paying cash), property taxes, insurance, utilities, and lawn care. These add up fast.
- Selling Costs — Agent commissions (typically 5-6% of sale price), seller closing costs, transfer taxes, staging, and marketing. These are the costs most beginners underestimate.
The 70% Rule Explained
The 70% rule is a quick screening formula used by fix-and-flip investors to determine the maximum purchase price:
Max Purchase Price = ARV × 70% − Rehab Costs
The 30% cushion is designed to cover closing costs, holding costs, selling costs, and profit. It's a guideline, not a hard rule — in hot markets, many successful flippers operate at 75-80% of ARV. In slower markets with more risk, you may need 65% or less.
Our calculator goes beyond the 70% rule by computing your actual costs and profit, so you can make data-driven decisions rather than relying on a rule of thumb.
Tips for Maximizing Flip Profit
- Buy right — Profit is made at purchase, not at sale. The biggest variable in your control is the acquisition price.
- Speed matters — Every month of holding costs eats into profit. Have contractors lined up before you close.
- Know your ARV — Pull comps from the last 3-6 months within a 0.5-mile radius. Be conservative — it's better to be surprised on the upside.
- Budget for the unexpected — A 10-15% contingency on rehab costs is essential. Foundation issues, mold, and electrical problems are common in distressed properties.
