4x1 - Flip or Flop

Tarek and Christina spot a home that's for sale by its owner in La Puente, California. It's in rough shape to say the least and because it's tenant occupied, they can't look inside. There's always a danger in purchasing a house sight unseen, but if they can get it for the right price, this home has the potential to pay off big time. Can Tarek and Christina right this sinking flip or could this home prove to be the stuff of wreck and ruin?
