I mean I like the character but I wouldn't live in it.
It's clearly being sold as a piece of art rather than a house. Almost anyone buying that as a house is likely to repaint in quite short order. But are you allowed to?
It will be very interesting to see what it sells for and whether the new owner actually lives in it.
Edit: given that it's being sold with furniture and artwork, I wonder if they're hoping someone will turn it into a museum?
