I've had dealings with DSI Schmolke Immobilien property management three times so far. They've taken over the management of our apartment complex, and I've been pleasantly surprised. With our previous property management company, communication was often cumbersome. It wasn't always clear whether to submit requests by phone, email, or via the app. Furthermore, the app wasn't particularly user-friendly. With DSI Schmolke Immobilien, things have been significantly better so far. Requests are addressed quickly, communication is clear, and you get the feeling that things are being dealt with promptly. If this standard is maintained, I'll be very satisfied.

Dr. Schmolke apparently finds ample time to write lengthy justifications on online portals. In day-to-day operations, however, urgent letters are ignored, collections of resolutions are not kept up-to-date, special assessments are requested without resolutions, and agenda items are omitted. The procedures are neither legally compliant nor orderly.

We are very satisfied with Dr. Schmolke Property Management. Their processes are reliable, and the management team is available by phone during certain hours. Outside of these hours, inquiries can be easily directed to the digital assistant; requests are processed promptly. The transparent casavi service portal for properties is a particular advantage. Owners can track the status and processing of their reports and leave comments at any time. Furthermore, contact persons and important documents such as the declaration of division, contracts, etc., are clearly stored there.

Excellent collaboration! We at Sunny Gebäudedienstleistungen GmbH have been managing the properties of Dr.-Ing. Schmolke Immobilien GmbH as a service provider for 5 years. The process is well-structured, the team is incredibly friendly, and coordination is seamless. It's a partnership that offers genuine added value for both sides. Highly recommended!

More Show Than Substance After initially good work, the Schmolke property management company has unfortunately proven to be a complete disaster. Simple tasks like organizing the annual window cleaning or replacing the heating meters were botched, owners' association resolutions were either not implemented or only after repeated reminders, and inquiries were either ignored or only addressed after repeated reminders. To this day, we have not received a proper statement of accounts for 2024, and questions regarding the preliminary statement are simply ignored. Mr. Schmolke himself shows no capacity for criticism and considers himself and his management company to be highly professional and infallible. He seems to be solely concerned with public image – he reacts immediately to negative online reviews and has them promptly deleted from Google (we'll see what happens with this review). The positive overall rating of Schmolke Immobilien should therefore be taken with a grain of salt. After it became clear that the management contract was to be terminated by mutual agreement, the management company almost completely ceased its work, in breach of contract. Our owners' association is now taking legal action against this, as well as against the management's charge statement, which we believe to be unlawful.
