Shit, nothing's unsellable for the right price and/or if you find the right moron. Phil's been selling being the Blues Clues of vidya streamers for years because his audience is just that dented. It's that much like with his very clear unchecked BBC lust, Phil would want to sell at a median price at least, with a very below average house.
And it's not wrong or a delusion, it's a certainty in the snortex: Phil is unbelievably greedy. His creed is GIVE ME MORE. He'd whine and cry that he only got half a mil for the Snortfort. Almost any time he makes out like a bandit he immediately wants, you guessed it, more and better. And I believe he genuinely feels bad about not getting it.
On any given day, Phil gets several thousand times what he deserves, but it's not even half of what he wants. He also gets absolutely 0 comeuppance, but he still pretends like he's harassed 24/7.
I'd fucking buy the snortfort for 20K and fully renovate it to flip. Would Phil be willing to sell at that price? Hell no, he'd want to pay no mind to the shitty location, no central air, water damage and other issues and sell at just about the price of any other condo in the gated community, even the ones that have their own garden. That's just his nature.
That community was made for people to work at Boeing from the get go, and I believe Phil bought it because in his infinite dentedness, he believed he could easily parlay his way into a high paying do-nothing job at Boeing nearby in case the streaming thing didn't pan out.
The housing market is kinda fucked anyway. You CAN sell houses, if you're willing to sell low, because blackstone and the like aren't about to pay you market rate, and common people can't afford a house now. And I doubt Phil is willing to sell. The only way he'd do it is if Khet wanted to get a divorce, but realistically he's already given up the lower floor of the Snort Fort to her so she can bring Tyrone over whenever she likes. In practice she's already won the divorce and taken him to the cleaners. Half his shit is legally hers, for free, no court battle involved.
It'd be super funny if Khet got to making chocolate babies in Phil's house, but I doubt it's plausible. But yeah, it's just a hypothetical. If they were to sell, Phil would wanna sell high and be disappointed with the result even if it was, objectively, very favorable to him. They're not selling anyway. The Fat Kat's going nowhere.
And again, props to her, because going from being a demonslaying, borderline prostitute-for-survival potato to stealing the King Of Dents' snortfort from under his gouty nose is quite the step up.
