4-room Altbau apartment
Berlin-Mitte · Gesundbrunnen · 1908
Sales narrative
5.45 % gross yield on 108.5 m² of central Berlin Altbau
Target cold rent of €2,500/mo on a 4-room Altbau apartment produces solid cash flow from day one. Rent per m² sits at the modernised-Altbau band that Gesundbrunnen supports, well above the ortsübliche Vergleichsmiete floor.
Altbau character, not new-build margin
The 1908 stucco Altbau in a preserved streetscape is a different asset class than a peripheral new-build. Value is built through a modernised interior on an irreplaceable Altbau shell — no developer margin priced in.
Gesundbrunnen anchors demand — U8, S-Bahn, Panke
Zechliner Straße sits between U-Osloer Straße and Gesundbrunnen station. Walking distance to two U-Bahn lines, S-Bahn ring, and the Panke green corridor. Tenant pool: young professionals commuting into Mitte and Wedding tech clusters.
Investment & financing
Refurbishment scope is structured for §6 Abs 1 Nr 1a EStG classification — below the 15 % threshold within 3 years — so modernisation can be Werbungskosten rather than capitalised. Materially improves after-tax equity efficiency.
Model at +3 % capital appreciation p.a., non-binding.

Location story
Zechliner Straße sits inside Berlin's inner ring in the Gesundbrunnen locality of Mitte — an Altbau district on the Panke river, walking distance to Volkspark Humboldthain and the Gesundbrunnen S+U interchange.
The street's building stock is Wilhelminian-era stucco Altbau, largely built between 1900 and 1910. Zechliner 9a is a 1908 façade in a preserved section — the streetscape is protected from new-build infill.
Two U-Bahn lines (U8 Osloer Straße, U9 Nauener Platz), the S-Bahn ring at Gesundbrunnen, and dense bus network. Tenant profile: young professionals working in Mitte's tech, media and government clusters.
