No clue. I do know that I found a lot of shacks and little houses with my big sis in Johto and Kanto, but this one takes the cake.

It shouldn't be too hard to clean up. Getting electricity set up shouldn't be too tough if the house doesn't already have it, and I'm not sure about heat, but there are heaters that you can plug into electric sockets anyway.

[And contrary to when he was a little kid, he has the money for these things. It's definitely cheaper than trying to find a house like this.]
