Zombie House Flipping - Season 4 Episode 12 Hourglass

The Zombie flippers uncover a "flag lot" property--a house tucked behind another with a narrow access. There's a property line dispute with the neighbor, but the lakefront location and low price are too tantalizing to pass up. The team sets out to resurrect this ragged two-story, battling flimsy construction and sinking floors, only to learn that the property dispute might rob them of lake access completely.
