Berlin New Lettings vs. Existing Rent: Why the Prices Are So Far Apart
Pull up a Berlin apartment listing and compare it to the official Mietspiegel, and the gap is often surprising: the listing sits noticeably above the official average. That's not landlords overcharging individually, it's a structural difference between two completely different figures.
Two numbers, two meanings
The Berlin Mietspiegel 2024 puts the average net cold rent at 7.21 euros per square metre. That figure reflects existing rents, meaning contracts already running, many of them for years, and capped by the statutory increase limit (Kappungsgrenze).
A listing, on the other hand, shows the asking rent: the price at which a newly vacant flat is being re-let. That rent tracks the current market, not the historical contract.
How big is the gap, really?
Nationwide, the Federal Institute for Building, Urban and Regional Research (BBSR) puts the 2025 gap at around 43 percent: existing rents averaged 7.76 euros per square metre, while newly listed flats averaged 11.11 euros. In big cities like Berlin, where an especially large share of tenancies run long-term, that jump tends to be even more pronounced than the national average, because the gap between old contract levels and current market pricing is particularly wide here.
What this means for your search
If you're actively searching in Berlin, don't benchmark against the Mietspiegel average — benchmark against current listings for comparable flats in your target location, build age, and condition. The Mietspiegel still matters, though: it's the legal reference for the rent brake (Mietpreisbremse), which caps new lettings in tight housing markets at no more than 10 percent above the locally typical comparison rent. For a full breakdown of that baseline figure, see our Berlin Mietspiegel 2024 explainer.
How to spot a realistic listing
The per-square-metre price isn't more than around 10 percent above comparable flats in the same neighbourhood
Build year, renovation status, and fittings explain the premium over the Mietspiegel value
The advance payment for additional costs (Nebenkosten) looks realistic, nationwide averaging 2.28 euros per square metre according to the German Tenants' Association

Frequently Asked Questions
Why are Berlin listings more expensive than the Mietspiegel?
The Mietspiegel shows existing rents in running contracts, while listings show the current asking rent for flats being newly let. Nationwide, the BBSR puts that gap at around 43 percent.
Is a higher asking rent automatically overpriced?
Not necessarily. The rent brake limits new lettings in tight markets like Berlin to no more than 10 percent above the locally typical comparison rent, with exceptions for extensively modernised or newly built flats.
What's the existing rent according to the Berlin Mietspiegel 2024?
7.21 euros per square metre in net cold rent on average, according to Berlin's Senate Department for Urban Development, Building and Housing.
How can I check whether an asking rent is fair?
Compare the per-square-metre price with similar flats in location, build year, and fittings in the same district, and use the Mietspiegel as a reference point if you're unsure.
