Housing Fraud Investigation (Real Estate)
Housing fraud is a growing problem in the Dutch housing market. Social housing illegally sublet via Airbnb or Booking, tenants who do not live at the address but sublet the property, or individuals who register at an address for benefits while living elsewhere — this costs housing associations and landlords millions annually. But it is not only about money. Housing fraud displaces people who are entitled to a home, causes nuisance, and can be a breeding ground for criminal activities.
What we investigate
What forms of housing fraud do we investigate?
Illegal subletting: the tenant rents the property (partially) to third parties, often via online platforms. Fictitious tenancy: the tenant is registered but factually lives elsewhere. Address fraud: individuals register at the address without actually living there, often for benefits. Unlawful use: the property is used for commercial activities, cannabis cultivation, or other illegal purposes. Overcrowding: structurally more persons reside than permitted under the rental agreement.
How does a housing fraud investigation work?
Step 1 — Report and intake: you share your suspicions and available information. We assess feasibility and advise on the approach. Step 2 — Investigation: observation, address verification, digital investigation (online platforms, social media), and neighbourhood research where needed. Step 3 — Evidence report: a factual report with findings, visual evidence, and timeline — prepared for use in lease termination proceedings. Step 4 — Legal advice: we advise on next steps — formal notice, termination, police report, or collaboration with the municipality.
