Chantal and Keith's dream is to own a lakefront house, but their picky nature has stopped them from settling for anything less than perfect. Overall, they have seen 300 properties but have yet to find "the one." Their 301st tour takes them to a grand estate with a castle-like interior and indoor pool. House number 302 is a sprawling home with a large living room, six-car garage, home theater, and outdoor resort. Finally, the 303rd home is an art deco-inspired house with large bay window views of the lake, a private library that walks out to a secret garden, and gorgeous grounds. Will any of these luxurious homes meet Chantal and Keith's high expectations?
