It depends on how long you plan to stay and how prices compare with rents. Because you first need to earn back the buying costs, buying in Cologne usually beats renting after 3–5 years.

Signs that buying makes sense for you:

• You plan to stay at least 5 years
• The purchase price is less than about 25 times the annual rent for a similar apartment
• Your monthly mortgage payment would be close to your current rent

Compare both options with the rent or buy calculator and read Rent or buy in 2026. Your monthly payment depends on today’s mortgage rates.

Start with the average for your postal code above, then adjust for your apartment:

• Size: smaller apartments sell for more per m²
• Floor and light: upper floors with a lift and a balcony sell for more
• Condition and energy standard: a renovated apartment with good energy efficiency is worth considerably more
• Tenancy: a tenanted apartment sells for up to 30% less than a vacant one

Every month, we value a fixed set of reference apartments (40, 60 and 100 m²) and houses (120, 180 and 240 m²) in each of the 1 postal codes of Wahnheide, across different construction years, and take the median.

Because we value the same homes every month, the estimate reflects real price changes rather than which homes happened to be on the market. It’s an estimate, not a notarised sale price, so check recent sales and the specific apartment before you make an offer. Our mortgage FAQs and mortgage tips answer many more questions.
