Greystar’s investment strategy focuses on the development, acquisition, and management of high-quality rental apartments, student accommodation, and innovative urban living concepts. Germany and Austria are at the heart of this strategy, with robust economies, strong urbanisation trends, and rising demand for attainable and sustainable housing solutions.
