Method
Every rental listing Flat Spain harvests is put through the deterministic half of the Flat Spain 16-Point Scam Screen at the moment it enters our inventory — not when a customer pays for a search, which would make the sample a record of what customers asked for rather than of what the market is offering. The index counts the share of those listings carrying at least one fraud-type flag in the calendar month they were screened.
A flag is a reason to check, not a verdict. Bait pricing can be a mis-typed rent; a missing street address is often just how a portal renders a search card. The critical rate — money requested before a viewing, an owner claiming to be abroad, payment by Wise or crypto — is the figure that behaves like a fraud signal, and it is the one to quote.
Two limits worth stating. The price-bait check compares against the city benchmark rather than a per-barrio one, because the per-barrio figure needs enrichment we do not run at ingest — so it is slightly blunter here than in a paid report. And a slice below 120 screened listings is not published at all.

Frequently asked questions
Which Spanish rental portal has the most scam listings?
Flat Spain publishes the flag rate per portal every month on this page, from its own screening of harvested listings. A flag is a reason to check a listing, not proof of fraud — the critical rate is the figure that behaves like a fraud signal.
How is the Spain Rental Scam Index calculated?
Every listing Flat Spain harvests is put through the deterministic half of its 16-Point Scam Screen at ingest. The index is the share of screened listings carrying at least one fraud-type flag, grouped by city and portal, for listings screened in that calendar month.
What counts as a scam signal?
Bait pricing far below the area rate, an owner or agent claiming to be abroad, money requested before a viewing, payment by Wise, Revolut, crypto or gift card, pressure language, and seasonal framing used on a long-term let.
