Mark and Elizabeth Perez are masters of their craft — seeing the potential in dilapidated properties, morphing them into the treasure of the block and selling them to first time home owners at a price they can afford. In the last 8 years, the Perez duo have flipped over 100 in Chicago, IL. This Mexico-born couple are always on the hunt for a diamond-in-the-rough. After a lot of demolition, repairs, paint, and elbow grease, they turn these ramshackle properties into gorgeous family homes.
