  Homes.com publishes no trust center of its own — trust.homes.com is NXDOMAIN
  and every path on www.homes.com returns HTTP 403 to non-browser clients behind
  Akamai bot protection. The trust center recorded here belongs to CoStar Group,
  Inc., the company that owns and operates Homes.com (acquired 2021, Homesnap
  folded in). It is the corporate security posture that governs the Homes.com
  property, but the portal does NOT name Homes.com, Apartments.com, Homesnap, or
  LoopNet in its covered-product list; the only products named explicitly are
  Visual Lease and CoStar Real Estate Manager. Read the certifications below as
  CoStar Group corporate scope, not as a Homes.com-specific attestation.
