Datafiniti Property Data vs HUD open data for AI agents
Datafiniti Property Data is a searchable US property database (API, portal and bulk download) that merges listing activity, tax/assessment and transaction data per property. HUD open data is a set of government datasets about HUD-subsidized multifamily properties (an ArcGIS feature service) and Fair Market Rents (HUD USER API); not a listings API.
The short answer
- Datafiniti Property Data: Bulk property and listing-history records for analysis and modelling, billed per record returned.
- HUD open data: Mapping subsidized apartment buildings and checking rents against HUD Fair Market Rents, not finding a vacant unit.
