German landlords are systematically overcharging rents by about €4,000 per year, undermining the country’s rent‑control policy
Executive summary: Private and commercial landlords in Germany were found to be charging rents roughly €4,000 above the legally permitted rent‑brake levels, according to data from legal service Conny. The widespread overcharge undermines the Mietpreisbremse policy, raising tenant housing costs and prompting potential regulatory enforcement.
Who is involved: Private landlords, commercial landlords, tenants, the legal service Conny, and German federal and local housing authorities.
Likely next: Authorities may increase inspections and fines, tenants could seek refunds, and policymakers may debate stricter enforcement or amendments to the rent‑brake law.
Data from the legal service Conny shows that private landlords in Germany are charging rents roughly €4,000 above the legally permitted rent‑brake levels, a level of overcharge comparable to that of commercial landlords. The finding highlights significant non‑compliance with the Mietpreisbremse, which is designed to keep housing affordable. If authorities act, landlords could face fines and tenants may be entitled to refunds, while rental yields might adjust downward.
