Flip or Flop

HGTV | 9:00 pm

Real estate experts Tarek El Moussa and Christina Haack return in five new episodes of their top-rated home improvement series, which follows the business partners and former spouses as they renovate and sell rundown properties while co-parenting their two kids. In the new "Fifties Flip," Christina convinces Tarek to take on a classic '50s property in Norwalk, Calif., but updating the vintage home and creating a more functional layout for contemporary buyers proves to be a challenge as they navigate a tight profit margin.
