What you get

Every field you'd expect from the MLS itself

  • Full property record (beds/baths/sqft/lot/year built)
  • Current price + recent price changes
  • List & sale history back to first record
  • Hi-res photo URLs in order
  • Listing agent name, brokerage, license, phone
  • Assigned school district + ratings

what's not in here

Off-MLS fields like internal showing notes, agent commentary, or syndication policy flags aren't in the Zillow surface — so we don't fabricate them. If you need raw MLS feed access (RETS/RESO), you'll want a board-licensed vendor.
