US real estate data: five listing sources compared
Five US listing sources, the tools that cover each, official API status and the field coverage that decides which one fits a lead list or market study.
Short answer
Zillow, Realtor.com and Redfin cover residential listings, Apartments.com focuses on rentals, and Crexi covers commercial property. None publishes a general self-serve listing API; Zillow and Realtor.com have partner access routes, while Redfin's public downloads contain market aggregates.
Portal coverage and API status checked 2026-11-12. How tools are ranked.Choosing a portal for this market
- For residential sale research, choose between search results and property details according to the columns you need. Zillow detail output includes agent, broker and mls, while search output includes cardType to distinguish home cards from apartment-building cards.
- For rental comparisons, check whether an Apartments.com record describes a property, a floor plan or a rent range. Keep that distinction when comparing records.
- For agent lead lists, select an agent profile tool. Realtor.com tools include agent contact and review outputs alongside separate property listing tools.

Questions people ask
Can Redfin Data Center replace listing extraction?
Redfin Data Center provides aggregate market downloads rather than individual listing records. Use those downloads for market summaries and a listing source when the work requires property addresses or individual sale records.
How should asking and sold prices be handled?
Keep the listing status alongside the price so asking and recorded sale values remain distinguishable. Zillow search output documents listingSoldPrice for sold records, while the listed Redfin tools vary in whether they expose soldDate or soldPrice.
Does Zillow search output include the same detail as property output?
Zillow search and detail tools expose different fields, with detail output adding fields such as taxAssessedValue, parking and broker. Search output also includes apartment-building cards that can lack price, bedrooms and bathrooms.
