Did they at least get $500 for selling the hotel on Boardwalk back to the bank?
Nope.
trump is going "directly to Jail. Do not pass GO, do not collect" anything.
I will be that guy
Monopoly rules don't actually say going to jail means other than landing on the space marked In Jail and being prevented from advancing your token on your turn. Every other deal is legal, including collecting rent if someone lands on your property while you're still in it.
Your turn ends immediately if you're sent to jail though, so no deals until the next turn. Chilling in jail can be strategic in the late game.
Since we are on the topic ...
Have you guys played Monopoly City?
https://boardgamegeek.com/boardgame/41186/monopoly-cityI think it is the best version of all the Monopoly games out there (I own it).
My nephew loves playing this game when he comes over to visit.
