Flip or Flop

HGTV | 9:00 pm

In the new episode "Covered Costs," Tarek and Christina take a big risk as they buy a house in Orange, Calif., sight unseen. Once they are able to gain access to the structure, they discover that the interior has been heavily vandalized, and the owners covered up a disgusting pool in the backyard. Other problems rear their head in an old addition, and a sloping concrete walkway outside also may cause trouble.
