Flip or Flop.

Tarek and Christina El Moussa buy distressed properties -- foreclosures, short sales and bank-owned homes -- remodel them and sell them at a profit. At least, that's the way it's supposed to work. Track the El Moussas' roller-coaster journey in each episode, beginning with a cash purchase at auction of a home -- often sight unseen -- and the fix-it-up process, to the nail-biting wait to find a buyer.
