Attorney Fred Royce bought his home called Henderson Castle in Kalamazoo, Mich., more than 20 years ago. He has recently turned into a bed-and-breakfast. As much as he loves his home, he has discovered another passion a world away--the beautiful Buenos Aires, the capital of Argentina. He wants to make the city his new home base and has set his sights on one of the ritziest areas. Helping him with his search is real estate agent Michael Koh.
