4x7 - Flip or Flop

Tarek and Christina get a lead on a home for sale in Chino, California that's rundown, overgrown, and in desperate need of cosmetic help. The price is fair and recent sales in the area show potential for profit. But right away there's a problem and Tarek and Christina are left wondering if this is an isolated issue or sign of what's to come. Will they turn a profit on this home or could mounting problems threaten to topple this trickle down flip?
