House Flipping

How these numbers were built: the flipping engine is a project model. Profit per flip is sale price minus purchase price, rehab, holding cost, and selling costs; the year is the sum of those spreads minus staff, deal sourcing, office and admin costs, and the page shows that year as a month’s average. The headline margin is profit over SALE PRICE, which is why it reads around 8 percent even when profit per flip is large; this is lumpy project income, not recurring revenue. The default resale price, the hold and the cash share of purchases come from ATTOM’s 2025 year-end home flipping report; profit per flip and the owner cash flow (SDE) margin come from FlipperForce’s analysis of 25,119 deals; hard-money terms come from FlipperForce, and SBA ineligibility from 13 CFR 120.110; rehab costs come from HomeGuide and HomeAdvisor cost guides, with BLS carpenter wages (SOC 47-2031) as a labor context; establishment context comes from the U.S. Census Bureau (NAICS 531390); and firm entry, exit, and survival come from the Census Business Dynamics Statistics. The opening kit prices the first house, its rehab trade by trade, closing, insurance and carry from pages checked in October 2026. These are starting assumptions; the moment you enter a real deal’s purchase price, rehab budget, carry, and resale comps, your numbers should replace ours.

The resale price and hold come from ATTOM’s 2025 flipping report, and profit per flip and the margin band from FlipperForce’s deal data (25,119 deals); the 7% to 13% band applies that median to a year after overhead and is not a single published figure. The purchase and rehab ratios are planning ranges for disciplined buyers; the median 2025 flip paid about 80% of its resale price.
