Property taxes inherited from parents

Hello,

My parents are in a different country. Most of their assets is on their name. They are planning to put me as the owner of the current house in which they are living in. We dont rent the apartment. My parents will live in the house. Will this be a taxable event and if yes, how should i calculate the tax on this ? Similarly, I want to know what are the documents I should ask my parents to keep ready to make the tax situation easy for me ?
