Who is buying these homes?

This 400sq ft shed that sold for $80k in 2010 is on the market for $450k!!!! No way some sucker is going to pay this right? I imagine you have to be single or a couple not wanting kids to live somewhere like this. Who is buying these places? Do they live there long term? Only other thing I can think of is some investor getting these and ripping college kids off with rent. Charleston is sinking , floods, and has the risk of hurricane so I can't grasp spending this much on a tiny shack that could one day be under water.
