4x6 - Flip or Flop

Tarek and Christina get a lead on a house in Torrance, California that is not only in rough shape, but also has known foundation issues. Right away it seems like this might be a bad buy; but Torrance is an exploding market and the land value alone could make this flip worth the risk. The house is going to need it all: good design, structural improvement, and careful renovation. It's a big project but it has the potential to be a big profit. Can Tarek and Christina transform this down and out home or could significant problems leave their budget and their profit margin on the verge of breaking up?
