Why owners switch

Three reasons traditional property managers fall short.

Sound familiar?

Calls go unreturned. Emails sit unanswered for days.

What is the property manager actually doing? You find out at the annual report — or not at all.

The percentage fee sounds small – until rent goes up or extra services get billed separately.

Personal advice for owners from Nicole Sterchi – RESONUS IMMOBILIEN

I want to finally delegate.

Multi-family building · Long self-managed

You've been managing it yourself for a long time – or you're finally ready to let go. You want relief, a dedicated contact person, and a handover that runs smoothly and reliably.

This is my situation

I only have one unit.

Single-unit mandate · Retirement home, inheritance, or STWEG rental

Whether it's a former home of your own, an inherited unit, or a unit alongside your existing STWEG (condominium owners' association) management: we're happy to take on a single-unit mandate too – at a fair flat rate.

We manage as a company.

GmbH / AG · Trustee · Broker · Estate management

You own properties as a GmbH or AG – or broker deals as a trustee, lawyer, or real estate agent. You need a reliable operational partner: clean reporting, clear responsibilities, professional communication.
