7x5 - Flip or Flop

A seller is looking to offload a three-bedroom, two-bathroom home in Garden Grove, CA, and asks Tarek and Christina to come have a look. The home already has an open floor plan and a master bedroom, but one of its bedrooms may be illegally permitted which could lead to hidden costs. Have they bought into a money trap or will they be able to pull out a profit on this infringing flip?
