The housing market in Cologne remains challenging territory for renters in 2025. Rental prices in the Rhine metropolis are among the highest in North Rhine-Westphalia – and they continue to rise. Driven by high demand and limited supply, anyone currently searching for an apartment quickly realizes: affordable offers are rare, especially in central locations.
But how exactly are rents developing in different districts? And what do you pay per square meter depending on apartment size?
Rental prices in Cologne rose significantly in late 2024 and early 2025. According to the German Economic Institute (IW), Cologne recorded a rental increase of 4.5 percent in the last quarter of 2024 compared to the same quarter the previous year. While the cathedral city is slightly below the nationwide average of 4.7 percent, it still moves in a concerning range for renters.
Regional Differences: Where is Housing Still Affordable?
Rental prices in Cologne vary significantly by district. Current data from mietspiegeltabelle.de shows clear differences between individual districts:
These figures illustrate that between the most expensive district (Lindenthal at €18.02/m²) and the cheapest (Porz at €11.42/m²), there's a difference of over €6.60 per square meter – a gap of almost 58 percent.
Why these extreme differences? The high prices in Lindenthal and the city center reflect central location, good infrastructure, and high quality of life. Lindenthal scores with proximity to the university, many green spaces, and excellent transport connections. Ehrenfeld has developed into a trendy district attracting young professionals.
On the other hand, districts like Porz and Chorweiler offer significantly cheaper rents. While Porz is somewhat outside the center, it has good S-Bahn connections and Cologne/Bonn Airport nearby. Chorweiler in the north of the city offers attractive prices especially for families with larger housing needs.
Kalk's position is also interesting: At €13.70/m², the district is in the lower middle range, despite having good transport connections and becoming increasingly popular - price increases could be expected here in the coming years.
Apartment Size as a Decisive Factor
A particularly important aspect of Cologne rental prices is the significant influence of apartment size on the price per square meter. Data from mietspiegeltabelle.de shows a clear pattern and illustrates how much Cologne exceeds the North Rhine-Westphalia and federal averages:
Cologne Significantly Exceeds NRW: The figures show that Cologne renters pay considerably more than the NRW average across all apartment sizes. The difference is particularly drastic for small apartments: At €19.18/m², Cologne residents pay over 50% more for apartments between 20-35m² than the state average of €12.59/m².
Why are small apartments so expensive? Several factors drive prices for micro-apartments up: High demand from students, career starters, and singles meets limited supply. Additionally, there's a structural cost problem that particularly burdens small apartments. Kitchen and bathroom are among the most expensive rooms in an apartment – due to complex installations, sanitary facilities, tiles, and fitted kitchens. These costs occur largely independent of total size: Whether 30 or 80 square meters – bathroom and kitchen cost similarly. In small apartments, however, these rooms make up a significantly larger proportion of total space. While bathroom and kitchen comprise about 15% of an 80m² apartment, they're already 40% in a 30m² unit. High construction and maintenance costs are thus distributed over fewer square meters – directly resulting in higher rents per square meter.
The Mid-Range Advantage: Apartments between 60 and 75 square meters offer the best value for money. They're large enough for couples or small families but not as sought-after as very small units. This size often corresponds to the classic 2-3 room segment. These apartments fall out of the "micro-apartment hype" but aren't yet large enough for the luxury market. At the same time, the ratio of usable space to "expensive rooms" is optimal – bathroom and kitchen only make up about 15-20% of total space, instead of 40% as with small apartments.
Large Apartments: Luxury with Premium. From 75 square meters onward, prices rise slightly again. Here the "luxury factor" comes into play – larger apartments are often found in better locations with superior fittings. For families with higher incomes who need more space, this category remains the only option despite higher per-square-meter prices.
From this size onward, landlords target a more affluent clientele: families with children, high earners, or seniors with good pensions and higher standards. These apartments are disproportionately often located in popular districts, feature balconies or terraces, and frequently have superior fittings. The slight price increase also reflects lower demand - fewer people can or want to afford 100+ square meters in Cologne, which paradoxically drives prices per square meter up again.
Practical Tip: Those flexible with apartment size can save over €5 per square meter by choosing a 60-75m² apartment over a 30m² unit – that's over €325 less rent per month for a 65 m² apartment! At the same time, even Cologne's cheapest segment still costs €4.91 more per square meter than the NRW average. From this size onward, landlords target a more affluent clientele: families with children, high earners, or seniors with good pensions and higher demands. These apartments are disproportionately often located in popular districts, feature balconies or terraces, and frequently have superior fittings. The slight price increase also reflects lower demand – fewer people can or want to afford 100+ square meters in Cologne, which paradoxically drives prices per square meter up again.
Concretely, this means: A 35m² apartment in Cologne costs an average of €671, a 65m² apartment "only" €909 – just €238 more for almost twice the space. Those moving to Cologne from elsewhere should prepare for significantly higher rents: Even an affordable 65 m² apartment in Cologne costs about €320 more than a comparable apartment at the NRW average. This price difference should definitely be factored into salary negotiations or budget planning.
Market Dynamics: Supply and Demand Determine Price
The ongoing price increase has structural causes. The IW attributes the development to high demand with insufficient supply. Particularly problematic is the stagnating number of completed new constructions. Nationwide, only about 260,000 new apartments were completed in 2024; for 2025, researchers predict even fewer with only around 230,000 apartments.
This development will likely continue in 2025, as the tight housing market offers no prospect of quick relief.
Purchase Market Shows Different Tendencies
While rental prices rise, Cologne's purchase market shows different development. Contrary to rising rents, purchase prices for real estate in Cologne fell by an average of 0.8 percent. However, IW researchers expect rising prices for residential real estate again in 2025, as stable to declining interest rates with rising incomes are expected.
Long-term Price Development: A Look Back
The dramatic development of rental prices in Cologne becomes clear when considering a longer timeframe. According to wohnungsboerse.net, a square meter cost an average of €9 in 2011; today it's already over €15 – an increase of more than 65 percent in about 14 years.
Legal Framework: The Official Rental Index
For legally binding rent increases, the official rental index is decisive. This is prepared every two years by the Rhineland Real Estate Exchange in cooperation with house and property owner associations, the tenants' association, the City of Cologne, and free and cooperative housing companies. Tenants and landlords should always refer to this official rental index for specific rental questions.
Conclusion: Challenges and Outlook For Rent In Cologne
Cologne's rental market remains a challenge for apartment seekers in 2025. With an overall average of €15.12 per square meter and continuing upward trend, affordable housing is becoming increasingly scarce. However, the considerable regional differences – from €11.42/m² in Porz to €18.02/m² in Lindenthal – still offer room for cost-conscious renters.
The structural problems of the housing market – too little new construction with high demand – will likely not be resolved quickly. Renters must therefore prepare for continued rising prices, while the purchase market may gain momentum again.
