Can foreigners buy property in the Netherlands?

Yes. There are no restrictions on foreigners buying property in the Netherlands. You have the same rights as a Dutch buyer, whether you hold an EU passport or not, and you do not need residency to purchase. What you do need is a BSN number, a Dutch bank account for the transfer, and a notary to handle the deed. Getting a mortgage is a separate question and depends mainly on your employment contract and income rather than your nationality. Non-EU buyers with a valid residence permit get Dutch mortgages regularly.
