Why this matters
The law sets a ceiling.
Most renters never see it.
Under the Mietpreisbremse, most Berlin re-letting rents are capped at 10% above the local reference rent. But asking prices on listing portals don't show this ceiling — and most apartment hunters don't have the data to calculate it themselves.
§
The data exists. It's just hard to use.
The official Berliner Mietspiegel maps 13,000+ streets across 163 rent categories by location, building year, size, and features. We do the lookup for you — instantly, for any Berlin address.
When you can see the estimated gap between an asking rent and the Mietpreisbremse cap, you're making decisions based on data — not just what the landlord listed. Knowledge of the legal framework may inform how you approach a tenancy.
Claims services may recover overcharged rent on your behalf — but they typically keep months of savings as their fee. A Mieterverein membership costs roughly €50–90/year. Rentkompass gives you the estimate for free, so you can choose your own path.
