Located at Wilhelmstrasse 44–46 in the heart of the Hessian state capital, close to the State Theatre and the Kurhaus, the property stands out for its high specification, excellent energy efficiency ratings and sought-after mix of uses. **Prime location in Wiesbaden for residential and commercial use** “We are delighted to continue our trusted collaboration with our investor through this acquisition and, at the same time, to complete our first joint acquisition in Wiesbaden. With the property on Wilhelmstrasse, we are securing a high-yield asset in a prestigious location, distinguished by strong demand in the residential segment and stable income from the commercial units,” says Martin Berghoff, Managing Director at Quantum. Built in 2019, the property comprises 34 residential units and four commercial units, with a total lettable area of around 4,380 sq m, divided into approximately 2,800 sq m of residential space and approximately 1,580 sq m of commercial space.
