About OTTO

About OTTO

Independent. Owner managed. Innovative.

Tradition paired with Innovation

A company that started as a small property management more than 65 years ago has developed into one of the top three real estate service provider in Austria under the leadership of Dr. Eugen Otto. Today we offer a wide range of real estate services. We manage, assess, sell, lease, within all asset classes such as residential, commercial, capital markets and Viennese Zinshaus. 

Commitment paired with know-how

Our story makes us proud, but we are even prouder of the over 90 employees who made this success possible. The many years of experience and the vast know-how of our team lay the foundation for customer satisfaction. Many of them have been working with us for generations.

Our success 

Rooted in Vienna, connected to the world

Through the exclusive partnership with Knight Frank, one of the world's leading private and independent real estate consultants, we offer access to international expertise and real estate. We also attach great importance to industry cohesion, that is why we are members of other international associations such as the FIABCI or RICS.
