Statistics Finland's rent statistics rely largely on Kela's housing allowance register, so they lean towards lower-income tenancies and may underestimate free-market asking rents, especially in popular urban areas. Treat the figure as a cautious estimate, not a market guarantee.

A high rental yield can come from a low purchase price, which may reflect risks in the area. Rental yield alone doesn't tell you whether a property is a good investment.
