I really hope that once Barb passes and assuming Chris inherits it outright or Cole gives his half of the house ownership to Chris out of his need for it, Rocky will help get 14BC fixed up to the minimum with possible help from the church and some sacrifices from the tugboat and Barb's savings (like new roof and missing windows replaced, appliances replaced with Goodwill appliances in decent working order or from a used-appliance store (there has to be one in R-Ville, C-Ville or both), gets the hoard removed by Junk-B-Gone or a similar service (Chris could probably clear the parts of the hoard in the bathrooms and his bedroom out and give it to the junk removal workers), and gets 14BC treated for spiders, bedbugs, ants, fleas and roaches, which is what I think the infestation is.
He could then look on Craigslist, take the Dodge van to places where there is free or cheap furniture and have a neighbor help him bring it in. Once 14BC is fixed up enough to be more or less livable but not pretty and the yard is taken care of, neighbors may help him with moving in furniture and the lawn, he could get CollegePro to paint the house for not much money (like half a tugboat or his survivor benefit payment from Bob's tugboat), he could paint the shutters, stairs and door himself with Krylon spray cans, and Rocky or another person from church (methinks his epistle is fairly old and he has gone back from time to time) could hook him up with automatic bill-paying and some supports. The tugboat would be mostly reserved for general needs, he could get food stamps fairly easily, but he could get Netflix instead of cable (costs way less) and focus mostly on playing used games from Goodwill and what he already has from PSN. Also, he should sell the Cadillac and BMW and keep the Dodge van.
Chris is trainable with the right assistance and with compassion, and 14BC can be fixed up into a marginal but livable place. He may eventually be able to meet someone who could be a girlfriend of sorts if he is given the opportunity to go to meet & greet groups with other autistic people... like Marvin says, what he says and what he actually does are 2 different things.
edit: as to how I know this... I am autistic as well (finally admitting it, my special interests are electronics, cars and crime), but received early intervention and treatment through the Denver public-school system draw a tugboat with added benefits from a parent, albeit caused by retirement and not death, have participated in autism meet & greet meetings, and am entering a vocational rehabilitation program. I could have EASILY ended up like Chris had I not been given treatment, and I know several cases of people like Chris who were trainable & reasonably successful once their parents passed on.

And AFAIK the reason Chris gets a bigger tugboat from Bob's demise but won't from Barb's is because I think Barb lives on a pension from Virginia Power (which is most likely a state job and a union job, so there is a pension involved), and not on a federal tugboat like Chris or a GE pension, patent royalties and Social Security retirement tugboat like Bob (which is how he could afford a Jaguar and a BMW).
