The 64% figure refers to the share of rental units only, not the total housing stock. When considering the total housing stock (including owner-occupied properties), small landlords own 37.3% according to IW Köln data.
The sources are from 2025, close to but before the claim date of March 2026.
The figure comes from a study by the Cologne Institute for Economic Research (IW Köln), not official government statistics.
