14 BC might be safe from Medicaid seizure, but it's certainly not safe from the mortgage lender. It's safe to assume that the payment is over $1000 a month, and though Chris's SSDI will increase after Barb dies, there's no way in hell he'll be able to afford the mortgage payment, property tax, and utilities on just his tugboat. So either he would have to get a refi (good luck given his credit score) or get a job (never going to happen). Either way, the fat autist is screwed.
Chris will not get a job. Let me explain why. Even if Chris worked full time minimum wage (and he's a tard so that's all he could get if he could even hold down a job), 40 hours a week and never taking a day off or having his hours cut, he would make $1900/mo, and that's not even counting taxes. Chris probably makes almost that much on his tugboat.
We don't know exactly what Chris gets. Chris gets 75% of whatever Bob's monthly retirement benefit was. The median retirement benefit in Virginia in 2020 was 1,545.50, so with a couple years of COLA, if Bob made a median income, Chris would be getting about $1200. However Bob was an engineer and probably significantly better paid than the median wage, so it's probably somewhat higher.
Bob retired at age 60, which would hurt his benefits, but we do know he was not well, and thought he did not have long to live, so if he was ruled disabled, then it would not hurt his benefits. Bob is a smart man so I don't think he would retire 5 years early without a plan.
SSDI of a disabled adult child is calculated based on whichever parent's benefit is higher, and it's pretty much guaranteed that Bob's (were he alive) is higher, so Barb's benefits do not come into play, really, except against family maximum.
This is a completely unscientific guess, but based on current median wage vs median wage for an engineer (*1.33 and I know that ratio would probably be different back then, like I said, unscientific), Bob's benefit should be about $2055.65 in 2020. Calculating in COLA for 4.7% 2021 and 5.9% 2022, that's $2279.25, Meaning Chris's monthly tugboat should be up to about $1700 by now. With Chris and Barb collectively capped at the family maximum.
I do not have the spoons to try to calculate their family maximum or if they're even hitting it. That limitation goes away anyway after Barb dies.
The mortgage payment was previously reported as $900, though I don't know how accurate that is.
Regardless, the tugboat is capable of supporting the mortgage, taxes, and utilities.
The problem is supporting the credit card debt. Chris would have to find some other means of funding. This is where section 8 comes in. If Chris rents a room at 14BC from Barb with HCV funds (if his social worker fast tracked him), then he should have enough to cover the debts. After one year he would qualify for HCV mortgage payments, as he would be a first-time homeowner, so if Barb lived for one more year he'd be safe.
I realize this is all fucking fantasy and Chris is almost certainly fucked, just saying that there is a way out if somebody figured it out and figured out how to stop Chris from fucking it up.
