The biggest reason I moved home was because my Mom moved out of the house and is in the process of turning it into a rental property. This means I get to live for free, in my own house, and all I have to do is help renovate. The first big project is the bathroom. It was always in a state of redecoration, adding one piece at a time, and it wasn't a horrible bathroom by any means, but it'll be so nice to start from scratch and really fix it up. It'll look so spiffy once it's done. There will be much less toxic mold as well. Always a plus.
