The dominant Finnish apartment ownership structure — you buy shares in a housing company (AsOy) entitling you to occupy a specific apartment. Transfer tax is 2% (vs 4% for direct real estate). Check the yhtiolan (collective mortgage) carefully.
The asunto-osakeyhtio (AsOy) — literally "housing limited company" — is the standard ownership structure for Finnish residential apartments. Rather than owning the apartment directly, you buy shares in the AsOy that owns the building. Each share or bundle of shares entitles the holder to the exclusive right to occupy a specific apartment as defined in the articles of association (yhtiojaarjestys).
AsOy ownership involves a two-tiered cost structure. The monthly management charge (hoitovastike) covers running costs: building maintenance, building insurance, communal electricity, heating, water, and AsOy management fees. Many AsOy also carry a collective mortgage on the building (yhtiolan or taloyhtiolan), and shareholders pay a separate financial charge (rahoitusvastike) to service their proportional share of this debt.
Financing AsOy shares: Finnish banks lend against AsOy shares at a transfer tax rate of 2% (versus 4% for direct real estate). Since 2019, Finnish law has moved AsOy share registers online through the Osakehuoneistorekisteri (OHR) maintained by Maanmittauslaitos, replacing physical share certificates. Buyers receive an electronic share confirmation.
Due diligence for AsOy purchases requires reviewing the yhtiojaarjestys (articles), the isannitsijantodistus (property manager's certificate disclosing the AsOy's financial status and outstanding charges), and the AsOy's PTS (long-term maintenance plan — pitkaan tahtaimen suunnitelma) for planned renovations. Major upcoming renovations can cost tens of thousands per apartment.
For foreign buyers, the AsOy system can be unfamiliar. You are buying shares, not a property; the AsOy board can restrict subletting; the collective mortgage is your inherited debt; and major decisions require shareholder votes.
In an AsOy purchase, you buy shares giving you the right to occupy a specific apartment. In direct real estate (kiinteisto), you own the land and building directly. Most Finnish urban apartments are AsOy; direct real estate ownership is more common for detached houses. Transfer tax: 2% for AsOy, 4% for real estate.
Generally yes — Finnish law allows subletting without board approval unless the yhtiojaarjestys explicitly restricts it. You must notify the AsOy board of the sublet and the tenant's details.
Request the isannitsijantodistus from the estate agent — this document discloses the total yhtiolan outstanding, the monthly rahoitusvastike per square metre, and the estimated repayment date. You can usually pay off your proportional share at purchase to eliminate the rahoitusvastike.
