New energy in Amsterdam: Renthouse finds a trusted partner in Interhouse

These are dynamic times in the world of residential letting. With shifting laws and regulations, the role of a letting agent and property manager has changed significantly. Landlords increasingly feel the need for more support, something that is newly confirmed every single day. This requires more dedication and (market) knowledge. Interhouse has a clear goal: growth, grabbing new opportunities with both hands and starting new chapters.

One of those new chapters began when Renthouse, based in Amstelveen, approached Interhouse. The collaboration between Renthouse and Interhouse has existed for more than 15 years and has always been grounded in shared values, mutual trust, and a joint belief: successful letting and property management must be personal, meticulous, and backed by knowledge.

Renthouse finds a trusted partner in Interhouse

After more than 55 years of service and three generations active in property letting and management, Renthouse closed an important chapter on 1 July 2025; the company has ceased its activities and the office has closed.

The property management division has been taken over by Interhouse vastgoedmanagement Lisse. These landlords have been informed and successfully transferred.

Former Renthouse clients who do not use property management services but do have questions about existing tenancy agreements or re-letting can contact Interhouse makelaars Amsterdam to ensure they remain in good hands. Interhouse makelaars Amsterdam has not formally acquired these clients or this portfolio from Renthouse, and therefore no obligations exist between the parties.

Landlords, tenants and fellow agents can continue to rely on personal service, specialist knowledge and worry-free property management.

Decades of experience added

As part of this transition, Marcel de Wijs has also joined Interhouse makelaars Amsterdam. This adds several decades of experience, expertise and an extensive network to our Amsterdam office and to the Interhouse group.

We look forward to supporting both existing and new clients. With short lines of communication, powerful systems and even greater strength, we are ready for the future.
