The Rental Scam Monitor
Every other number on this site comes from an institution that published it. These come from us: what our verdict engine actually returned on listings people asked us to check. Aggregated so far that no check, person or listing can be read back out — and free to quote, with attribution.

By platform
Where the checked listing was hosted. This measures the listings people brought us, not the platform — someone who already suspects a listing is the one who checks it.
| Platform | Checks | Flagged | Flagged rate | High risk |
|---|---|---|---|---|
| Other sites (pooled) | 51 | 22 | 43% | 8 |
49 checks were run without a listing link — a pasted advert, a chat screenshot or an IBAN on its own — and are counted in the total but not in this table.
By month
Rental-scam volume is seasonal; a single month is a season, not a trend.
| Month | Checks | Flagged | Flagged rate | High risk |
|---|---|---|---|---|
| 2026-07 | 49 | 30 | 61% | 24 |
| 2026-08 | 44 | 28 | 64% | 21 |
7 checks fall in months too small to publish and are counted in the total only.
Method, and what these numbers are not
- Source: every verdict our engine returned in the last 12 months, grouped inside the database by platform, month and verdict band. No individual check is read out.
- Suppression: any row describing fewer than 25 checks is pooled into “other”, and dropped entirely if the pool is also below 25.
- Selection bias, stated plainly: these are listings someone chose to check, usually because something already felt wrong. The flagged rate here is higher than the flagged rate of the Dutch rental market, and it is not a measurement of any platform's honesty.
- A flag is a risk signal, not a verdict about a person or a company. We never publish an address, an owner, a listing or a user.
