How do I find only private-seller (particular / FSBO) listings on Idealista?
Idealista mixes owner and agency ads and offers no particular-only filter, so the fastest way to see only private-seller listings is to read each listing's owner signal and keep just the owner ones — which FSBO Finder does automatically across every page of your search.
Why Idealista has no particular-only filter
Idealista lists properties from private owners (particulares) and from agencies (mediadoras) together. There is a professional/particular distinction in each listing's data, but the public search gives you no toggle to show owners only — so by hand you page through dozens of mixed results checking each one.
The manual way: page through and check each listing
You can open each listing and look for the owner-vs-agency indicator, then copy the ones that are private. It works, but a single search can span many pages, and you repeat the whole thing every time inventory changes.
The fast way: extract only the private sellers
FSBO Finder scrapes every page of your Idealista search, reads each listing's structured owner type, and returns only the private-seller listings — exportable as CSV with URL, price, typology, and area. It works on Idealista Portugal (idealista.pt), Spain (idealista.com), and Italy (idealista.it).
