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.
