Your real estate agent for Troisdorf and Niederkassel
Troisdorf is located in the Rhein-Sieg district between Cologne and Bonn and is one of the most dynamic places to live in the region. With a population of around 77,000, the city combines urban life, strong economic vitality, and an abundance of nature. The Agger and Sieg rivers shape the cityscape, as do extensive green spaces and floodplain landscapes—most notably the Wahner Heide, which borders the city directly and provides Troisdorf with a nearly unique recreational potential within the metropolitan area.
If you are a property owner planning to sell or rent out your property, or if you would like to buy a suitable apartment or house in Troisdorf or Niederkassel, we are happy to assist you as a reliable real estate agent in Troisdorf. We support owners, buyers, and investors with in-depth market knowledge, local experience, and a keen eye for micro-locations and realistic market values.
Troisdorf & Niederkassel – Living between the Rhine, Sieg, and the metropolitan region
Troisdorf impresses with a balanced blend of nature, infrastructure, and urban life. Walking and biking trails along the Agger and Sieg rivers, Rotter Lake, and the Wahner Heide offer recreational opportunities rarely found in this form in the Cologne area. At the same time, the city offers a diverse cultural and social life with Burg Wissem, the Kulturwerk, the castle park, and the downtown area.
The neighboring town of Niederkassel perfectly complements this profile: Located directly on the Rhine, with the highly sought-after neighborhoods of Mondorf and Rheidt, it appeals particularly to families, commuters, and workers from the Bonn area. The ferry connections, the Mondorf marina, and the Rhine promenade ensure a high quality of life and sustainably enhance the attractiveness of the real estate market.
Economy, Infrastructure, and Location Advantages
Troisdorf and Niederkassel benefit from excellent transportation connections. Cologne and Bonn are quickly accessible via the A59, the L269, and the direct S-Bahn connection. Cologne/Bonn Airport provides international connectivity. Troisdorf is also a major industrial hub: mechanical engineering, plastics processing, automotive supply, IT, and logistics characterize the mix of industries. Niederkassel complements this with a strong chemical and commercial sector.
This economic stability has a direct impact on real estate demand. Residential areas with good commuter connections, family-friendly infrastructure, and natural surroundings are particularly in demand—factors that we, as real estate agents in Troisdorf, consistently take into account during valuation and marketing.
Current Real Estate Market in Troisdorf & Niederkassel

In demand are single-family homes and townhouses in quiet residential neighborhoods, modern condominiums with good transportation links, and properties near water.
