Vacancy & Letting Risk in Cologne: what to know
Vacancy in Cologne stands around 0.8% (CBRE-empirica-Leerstandsindex 2024 (market-active vacancy, multi-family stock, Cologne), cited in Engel & Völkers Commercial Marktbericht…). Context: under 1% means structural scarcity (instant letting, maximum rent pressure), ~3% is a balanced market's natural fluctuation reserve, and higher values concentrate in specific districts and unrenovated stock rather than spreading evenly.
Managing the risk: buy where the city's demand drivers point (Innenstadt, Ehrenfeld, Lindenthal for depth of demand, Rodenkirchen and Mülheim for yield with selectivity), keep the unit's condition at or above district standard, and price at the Mietspiegel-defensible level rather than the top ask — one month of vacancy costs more than 2% of annual rent.
The Cologne market in numbers
Cologne (North Rhine-Westphalia (Nordrhein-Westfalen)) has 1,100,076 residents. Existing apartments currently average around €4,277/m² (district spread roughly €3,310–€6,310/m²), with new-builds at about €6,245/m². Average asking cold rent is about €14.7/m², putting the gross rental yield near 4.1%.
Price momentum: +1.5 to +3.0 (existing condos, Q3 2025 vs Q3 2024; new-build +4.5% YoY). Prices rose to a 2022 peak (~€4,660/m² existing, KAMPMEYER), corrected about 5–10% through 2023–2024 (2024: €4,430/m², −4.7% YoY), and have been stabilising and rising again since 2025.
Vacancy: roughly 0.8% (CBRE-empirica-Leerstandsindex 2024 (market-active vacancy, multi-family stock, Cologne), cited in Engel & Völkers Commercial Marktbericht…). That is effectively full occupancy — supply scarcity drives both rents and letting speed.
Where to buy in Cologne
Investment demand concentrates in Innenstadt, Ehrenfeld, Lindenthal, where letting is fastest and long-term value is most defensible. Value- and yield-oriented buyers look at Rodenkirchen and Mülheim, which trade lower and typically deliver higher gross yields with more management intensity.
Innenstadt (incl. Belgisches Viertel, Deutz): The historic and creative heart around the cathedral and the Belgian Quarter's cafés and boutiques — Cologne's most expensive and most liquid submarket. Apartments trade around €6,310–€8,140/m².
Ehrenfeld: Former working-class district turned Cologne's hippest quarter — street art, start-ups, media scene and strong gentrification-driven demand. Apartments trade around €4,890–€7,320/m².
Lindenthal (incl. Sülz): Green, upscale west-side district with the university, clinics and Stadtwald — classic family and academic territory with stable premium prices. Apartments trade around €4,840–€7,960/m².
Nippes: Lively, well-connected northern district with Altbau streets and a village-like market square, popular with young families priced out of the centre. Apartments trade around €4,290–€6,470/m².
Rodenkirchen: Leafy Rhine-side district south of the city with riverside promenades and villa quarters — quiet, affluent, strong owner-occupier demand. Apartments trade around €4,600–€7,450/m².
Mülheim: Right-bank regeneration story around Carlswerk and the Schanzenviertel media/tech cluster — entry-level prices with the city's strongest new-build momentum (+12.9% YoY new-build). Apartments trade around €4,030–€5,780/m².
Taxes & buying costs in Cologne
Property transfer tax (Grunderwerbsteuer) in North Rhine-Westphalia (Nordrhein-Westfalen) is 6.5%. Add approximately 2% for notary and land registry (statutory GNotKG fees) plus any brokerage/service fee — total acquisition costs typically run 8–12% on top of the purchase price, and German banks generally do not finance them.
Held privately, the property can be sold tax-free after the 10-year Spekulationsfrist; before that, gains are taxed at your personal rate. Depreciation (AfA) shelters rental income: 2% p.a. for pre-2023 buildings, 3% for buildings completed from 2023, and a 5% degressive option for qualifying new projects started before 30.09.2029.
Cologne is a designated tight housing market: the Mietpreisbremse caps new-lease rents at roughly 10% above the local comparative rent (Mietspiegel), and the reduced Kappungsgrenze limits in-tenancy increases to 15% within three years. Factor the achievable regulated rent — not the asking-rent headline — into your underwriting.
