Recognising Housing Fraud in Amersfoort

Housing fraud in Amersfoort — a problem behind closed doors

Amersfoort’s housing market has been under significant pressure for years. The city’s attractiveness as a residential location, combined with excellent rail connections and a growing local economy, has driven demand far beyond supply. In this tight market, housing fraud flourishes. Illegal subletting, registration fraud, phantom occupancy, and abuse of social housing allocations affect private landlords, housing corporations, and legitimate tenants alike.

Neighbourhoods such as Soesterkwartier, Liendert, and Kruiskamp are particularly affected. In older housing stock with relatively affordable rents, the temptation to sublet illegally or to register at an address without actually living there is considerable. For housing corporations such as De Alliantie and Portaal, which manage thousands of social housing units in Amersfoort, every fraudulently occupied home is one fewer available for people on the waiting list.

Warning signs that indicate housing fraud

Housing fraud takes place behind closed doors, making it difficult to detect without active investigation. However, several patterns should raise concern:

• The registered tenant is rarely or never seen at the property
• Different individuals are observed entering and leaving the property at irregular hours
• An unusually high number of people appear to live at the address relative to its size
• Post accumulates in the letterbox or is collected by someone other than the tenant
• Neighbours report persistent noise, unfamiliar visitors, or unusual activity
• Utility consumption is abnormally high or suspiciously low compared to similar properties
• The property appears on short-term rental platforms such as Airbnb or Booking.com

How SAJ Recherche investigates housing fraud

A housing fraud investigation by SAJ Recherche combines multiple investigative methods to establish the facts:

• Administrative research: verification of municipal registration (BRP) data, rental agreements, utility account holders, and tenancy records
• Surveillance: structured observation of the property to document who actually occupies it, how frequently, and at what times
• Neighbour interviews: discreet conversations with adjacent residents to gather information about occupancy patterns and observed activity
• OSINT investigation: systematic checks of short-term rental platforms, social media profiles, and online advertisements linked to the address
• Documentation: compilation of a comprehensive, timestamped report with observations, photographs, and supporting evidence

All activities are conducted within the framework of the Wpbr and the GDPR (AVG). SAJ Recherche holds a POB licence. The final report is suitable for use in legal proceedings at the District Court of Midden-Nederland, for example to support lease termination under Article 7:231 of the Dutch Civil Code, or to file a report with the municipality of Amersfoort.

Practical example from Amersfoort

A housing corporation managing properties in Liendert received a tip from neighbours that a social housing unit appeared to be occupied by people other than the registered tenant. The tenant denied any irregularity. SAJ Recherche conducted surveillance over a two-week period, documenting that the registered tenant was never present while two other individuals were consistently observed entering and leaving the property. OSINT research uncovered a room-rental advertisement on a social media marketplace matching the property’s interior. The corporation used the investigation report to initiate lease termination proceedings, freeing the unit for a legitimate applicant.

Act early to protect your property and the housing market

Housing fraud erodes the integrity of the housing market and causes direct financial harm to landlords and corporations. The sooner you investigate, the sooner you can act. Professional investigation provides the legally admissible evidence needed for effective action, whether through the courts, the municipality, or internal corporate procedures.
