Buy-to-let in Finland (sijoitusasunto)
How to stress-test rental yield against fees, company loans, renovations, and vacancy — before you buy an investment apartment.
A Finnish sijoitusasunto is usually housing company shares you rent out. Banks and tax rules treat it differently from a first home, so model cash flow carefully before you bid.
Start with realistic rent for the micro-location, then subtract hoitovastike, pääomavastike, water, insurance, and a vacancy buffer. Yield on asking price alone is not enough.
Company loan and upcoming renovations can crush yield. A cheap purchase that triggers a pipe renovation or rising finance fee may look worse than a pricier, well-maintained building.
Check articles of association and company practice for rental restrictions. Some housing companies limit short-term lets or require notifications.
Buy where you understand demand. Local knowledge of rents and price paths reduces the risk of overpaying for a unit that sits empty.
Diversify: one apartment can be part of a broader portfolio; rental cash flow is often steadier than short-term price moves, but leverage still amplifies mistakes.
Use Recompare-style monthly cost thinking and the renovation guide before you lock the loan amount — then stress-test interest rates and empty months.
