We all know that when Barb dies, Chris will end up homeless within a year.
The real question is what happens to the house. The bank will own it, but will obviously want to sell it. However, whenever you google "14 Branchland Court", the first result is the Cwcki. Potential home buyers are likely to google the address at some point, and they'll tumble into our den of autism.
Maybe some rich troll will buy the house and turn it into a Chris-chan living museum, with Chris himself as the main exhibit.
Okay, that almost certainly won't happen. But imagine it for a second. That would be a pretty good deal for Chris. He could even give tours.
