Koszalin Property Prices, Rents & Rental Yields

About Koszalin

Koszalin sits in northwestern Poland between the Baltic coast and the inland lake district, giving it a practical regional position with a distinct seaside-adjacent identity. The city combines everyday urban functions with access to wider West Pomeranian routes, which keeps it relevant for long-term residential interest.

September 2026 brought the clearest signal for apartment investors in Koszalin: rents are still edging up while sale prices soften. The average apartment sale price stands at 385,000 zł, down 1.0% month over month and only 0.9% higher than a year ago, while the average rent price has reached 2,000 zł after a 2.6% monthly increase. That mismatch leaves the gross yield at 6.89%, which is solid on paper but also reflects the pressure of holding costs against a more cautious sales market.

The broader pricing picture is mixed rather than directional. Average price per square meter is 7,700 zł, up just 0.2% over the month and down 2.7% year over year, suggesting that apartment values have not recovered evenly across the market. For investors, the tension in Koszalin is clear: income is improving modestly, but capital values are not rising in step, so return expectations depend more on rent growth than on price appreciation.
