Housing Fraud in Amsterdam — How Landlords Protect Their Properties

Housing fraud in Amsterdam — the scale of the problem

Amsterdam’s housing market is among the most pressured in Europe. With average rental prices far exceeding the national norm, the financial incentive for housing fraud is enormous. A tenant paying EUR 1,200 per month in social housing in Amsterdam-West can sublet the same property for EUR 2,500 or more on the private market. A registration address in Amsterdam provides access to municipal services, voting rights, and benefit entitlements. These incentives drive a thriving underground economy of illegal subletting, phantom occupancy, and registration fraud.

For landlords — whether housing corporations like Ymere and Eigen Haard, institutional investors, or private property owners — housing fraud represents a triple threat: lost rental income, property damage from unscreened occupants, and legal liability for activities conducted at the address. The municipality of Amsterdam actively combats housing fraud through its fraud investigation team, but individual landlords carry the primary responsibility for their own properties.

Forms of housing fraud common in Amsterdam

A housing fraud investigation addresses the full range of misuse:

• Illegal subletting: the registered tenant lives elsewhere while renting out the property at a markup, often through platforms or informal networks
• Holiday rental abuse: properties used as Airbnb or short-stay apartments in violation of municipal regulations and lease terms
• Phantom occupancy: someone maintains a registration at the address without actually living there, often to preserve benefit entitlements or social housing allocation
• Overcrowding: significantly more people living at the address than the lease or building permits allow
• Commercial misuse: residential properties used as offices, warehouses, or for other business purposes without authorisation

How SAJ Recherche investigates

The investigation combines multiple evidence-gathering methods:

• Surveillance: observation of the property over multiple days to document actual occupancy patterns
• Platform monitoring: OSINT searches across Airbnb, Booking.com, Facebook Marketplace, and other rental platforms
• Administrative research: verification of BRP registrations, utility accounts, and postal delivery patterns
• Neighbour interviews: discreet conversations with residents of adjacent properties
• Documentation: comprehensive report with timestamped observations and photographic evidence

Practical example from Amsterdam

A housing corporation managing a portfolio of 300 units in De Baarsjes and Oud-West suspected widespread subletting based on maintenance access patterns — many tenants were never home during scheduled visits. SAJ Recherche conducted a targeted investigation of the twelve highest-risk units, combining surveillance, platform monitoring, and administrative research. Seven units were confirmed as illegally sublet — three as Airbnb rentals, two to undocumented occupants, and two where the tenants had moved to other cities. The corporation used the individual reports to terminate all seven leases and recover the units for legitimate allocation.
