How to price your Berlin Altbau without a broker in 2025

Why getting the price right matters more in Berlin than anywhere else

Price a Berlin Altbau too high and it sits. Buyers in Prenzlauer Berg, Friedrichshain, and Mitte are well-informed — most are tracking the same few search alerts for months. A flat that appears and then drops in price three weeks later is a signal that something is wrong, even if nothing is. The psychological discount you impose on yourself by over-pricing is larger than the margin you were trying to protect.

Price too low and you leave money on the table. In a market with sub-1% vacancy, there is almost always a second buyer willing to match the first one. Getting to the right number from the start is worth the research.

Step 1: Research comparable sales (Vergleichswerte)

The German property market is not as transparent as the UK or US, but data is available if you know where to look. For Berlin:

• Immobilienscout24 and Immowelt show asking prices, not closing prices — but filter for sold or removed listings and you get a useful signal
• Gutachterausschuss Berlin publishes annual market reports (Grundstücksmarktberichte) with actual transaction data by postcode
• Local Makler websites often publish closed-sale case studies as marketing — these are genuine data points

Look for comparables within 500 metres, ±10 m² of living space, similar floor (ground floor and top floor diverge by ±10–15%), and within the same energy class. Three to five good comparables give you a defensible range.

One additional source that most private sellers overlook: ask a local notary's office what the average m² price has been for recently completed transactions in your postcode. Notaries are not permitted to share individual transaction prices, but many will give an informal range. This takes fifteen minutes and costs nothing, and notary-sourced data reflects actual closing prices, not asking prices.
