> They often have to rent the land they are on and get stuck there, as they can't transport the houses off. A few years ago I got interested in a trailer park nearby because homes were selling for less than two years of my income. After some research, I found that the lot itself is a 99 year lease from the city, parcelled by the park's management company. The land is situated in a rapidly developing neighborhood, and the lease expires in the next 2 years. If the land is sold from under you, you own several tons of trash that's not as mobile as it sounds. Even if you can move it, park spaces are hotly contested because all of your neighbors are in the same market at the same time. I ran away and never looked back.
