About this data
Flip transactions: Pulled from public county recording records via SFR Analytics. Filtered to investor purchases resold 28 to 540 days later (shorter holds are wholesale or assignment deals). New construction, rebuilds, iBuyers, homebuilders, multi-parcel sales, family transfers and purchases under $25K are excluded. Money-losing flips are included, so margins reflect the real range of outcomes.
Gross margin: Sale price minus purchase price. Does not include rehab, carrying, or closing costs. Use our Deal Calculator to model full project returns.
Demographics and rent: Population, median household income, and median home value from U.S. Census ACS 5-year estimates (2022). Rental figures reflect current listings from SFR Analytics.
Why we built this: Tier One Funding is a direct bridge and fix-and-flip lender. We built this free tool because flippers kept asking us, "What are the real numbers in my market?" and there was no free answer that wasn't buried behind a paywall. Use the data to decide where to buy, then call us when you need bridge capital.
