A deposit of 10% is usual but not necessary in Austria, returned if the sale falls through. Property sales are usually handled for both parties by a solicitor/lawyer. The purchase agreement and the documents can be signed before an official at an Austrian embassy abroad and translated if required. When the purchase contracts are signed the funds are deposited in a trustee (Escrow) account until completion takes place. The owner details will then be registered in the land registry and can take a few months. The taxes and fees are then paid by the solicitor/lawyer and the agreed purchase price paid to the vendor.
