Dealsheet

Data sources

Listing prices, value estimates, rent estimates and rental comparables come from the RentCast API, whose terms allow showing the data to users. Census and HUD data are U.S. government works. Mortgage rates are Freddie Mac's Primary Mortgage Market Survey via FRED (Federal Reserve Bank of St. Louis).

Default assumptions (closing costs, vacancy, repairs, management, insurance) are not data: they are common rules of thumb, labeled in every report and editable. Dealsheet never opens Zillow or Redfin pages; it reads the address from the link itself.
