We collect rental inventory from the places it is first published, normalise it into one schema, and deliver it through the Display Feed and the Data API. Our customers are housing apps, relocation services and nonprofits that show current rentals inside their own product.
Two products run on one database and are kept apart on purpose, because they carry different rights.
Manager-direct US rental listings, licensed for public display in your product with the manager named and linked. Delivered weekly with added, changed and removed records. About the Display Feed.
An internal-use dataset for research, analysis and internal tools, without display rights. It can include portal listings, which are held for measurement only. About the Data API.
We maintain a registry of rental-source websites and identify the leasing software behind each one, so we can collect listings directly from the source. Today that covers 40,000+ manager and owner websites across 43 software families, from the small landlord's management system to the leasing sites of large operators.
Each listing gets a stable id, a normalised address with coordinates, rent in its own currency and in USD, and three timestamps: first seen, last verified and last read. Every export passes an automated pre-delivery check. The numbers and their definitions are public: coverage by state and metro and how listings are verified.
The Display Feed comes with a written licence to show the listings, descriptions and photos in your product, with the manager named and linked. Property-data APIs such as RentCast, HelloData and Dwellsy IQ are built mainly for records, rent estimates, comparables and underwriting.
Listings are read from the property manager's or owner's own website and leasing software. Portal listings are held for measurement only and never enter the Display Feed. A portal scraper gives you a collection workflow to run; paying to run it does not by itself give you a licence to republish what it collects.
Every source is re-read weekly. Confirmed delistings arrive in a removed set, so a leased unit leaves your product instead of lingering. Each record carries three timestamps: first seen, last verified and last read. How verification works.
Each licence is quoted for an agreed scope, from one city to nationwide, and runs month to month with 30 days' notice. The free month starts when you first show our listings publicly. There is no per-request metering and no annual commitment.
HousingFeed is built by Iron Brands and Adriaan van Rossum in Amsterdam, and Iron Holding B.V. is the company behind it. Both are seasoned tech entrepreneurs, and the same people building the product handle customer questions and integrations. There is no sales layer.
HousingFeed began in July 2026 as a rental listings dataset on Apify and became a licensed feed when the first customers asked to show the listings inside their own products. The roadmap is set by what customers ask for.

RentCast is a property-data API for records, rent estimates, comparables and listings, priced per request. HousingFeed is a rental listings feed licensed for display, quoted per market and billed monthly. Full comparison.
Yes, under a Display Feed licence for the agreed use. Attribution to the manager and a link back to the source listing are required. The separate Data API is for internal use and does not include display rights.
Not in the Display Feed. Portal listings are held only for measurement and research, because display rights to them are not ours to grant. Every displayed listing comes from the manager's or owner's own site.
Every source is re-read weekly and confirmed delistings are delivered as removals. Records past the delivery freshness limit are excluded before export.
Each licence is quoted for its scope: locations, inventory and usage. Licences run month to month and the first month is free, starting when you first show our listings publicly. Pricing explains what shapes a quote.
Coverage is published by state and metro on the coverage page. For a specific market, ask for a sample: you see real records before you sign anything.
