It is certainly possible that Trump owns a lot of property that is highly leveraged and relatively little liquid assets.
There was a story in the WaPo about how he's been using cash purchases for real estate rather than debt financing, which is unusual and raises some questions.
The whole idea of being able to bribe him for like $200K is unusual if he’s a billionaire. If I was a billionaire, what the fuck do I care about $200K, really? That would be like being able to bribe me today for $500. I’m definitely not committing crimes at work for you for $500.
That said the shit certainly looks like a bribe.
But if he owns these places outright and bought them with cash, he should be able to borrow against them. Actually, using his own properties as collateral would be how you get the normal banks to lend to you again.
Something about the whole situation doesn’t make sense, and the idea that those properties he owns aren’t “his” properties because they are being used to launder money makes some sense.
