"Finland must take care of its own security in all circumstances," Defense Minister Antti Kaikkonen told AFP.
But "the need for further work has also been identified" and the ministry is studying whether a total ban on property purchases by Russian nationals and companies is necessary.
Prime Minister Sanna Marin told public broadcaster Yle on Sunday that she was "ready to consider" a total ban and "support it if the authorities deem it necessary".
The Finnish government had already proposed a bill last week aimed at restricting real estate transactions for foreigners who could threaten "national security".
The proposed text is an amendment to strengthen a 2020 law that requires transactions by individuals or companies outside the European Union or European Economic Area (EEA) to be approved by the Department of Defense.
Although the law applies to all non-EU nationals, "it mainly concerns real estate transactions carried out by Russian citizens and the security risks associated with it", Jonas told AFP. Kontta, a Center Party parliamentarian and member of the Defense Committee.
As it stands, the ministry can only intervene if a transaction compromises national defense, territorial integrity or border security.
The new text "broadens the radius" of this mechanism, Joona Lapinlampi, from the legal department of the Ministry of Defense, told AFP.
Thus, the new law could target an individual who would seek to buy a property in the immediate vicinity "of a ministry or a garrison".
The new text would grant more powers to the state to more closely investigate the financing of potential real estate transactions.
Finnish media reported last week on a deal in which a Russian citizen sought to buy an old retirement home with around XNUMX rooms near the Niinisalo garrison in the southwest of the country.
The Finnish Security and Intelligence Service (Supo) has warned that owners acting on behalf of a foreign state could allow their property to be used to house foreign troops.
