The couple, who are expecting their first child together, recently paid $11 million for a mansion in California.
They want to purchase three more properties in the three different cities, all of which are home to Kardashian Dash stores except Paris, reports showbizspy.com.
The couple have been in Brazil for the past few days to meet with an architect they are considering to hire to renovate their California home.
But they enjoyed their time in the South American country so much that they are now considering buying a property there too.
The couple wants to restyle their California house into an Italian-style villa. They are planning to install a gym, movie theatre, bowling alley, hair and make-up salon, indoor and outdoor pools and a basketball court.
