What counts as an official 1 Euro house source?
The strongest source is a page or PDF from a municipality, public housing agency, or notary-backed public sale. A travel article, marketplace post, or private broker page can be useful for discovery, but it should never be the final proof.
- Look for the town name plus terms like bando, avviso pubblico, case a 1 euro, immobili, or manifestazione di interesse.
- Check whether the page includes dates, application forms, deposit terms, property lists, and contact details.
- If the town only has old press coverage and no current notice, mark the program as historic until confirmed.
