I wonder if the whole Vegas thing was sponcon, like Bravo (and maybe the realtors themselves) were being paid to advertise the ridiculous Terra Firma development. There's no reason that Flagg would ever get involved in something like this if he didn't have to do it and he was truly doing the bare minimum, Tracy could totally see how ridiculous the development is, and even the Altmans' energy seemed forced.
The whole thing is bizarre because there are at least two different Terra Firma websites, one of which links to the other, but not in a super transparent way. The main website (it seems) says on the Team page that there are 30+ lots still available (confusingly the number of lots is not on the "Lots" page). If that's true, it's possible that aside from this Jeff guy, no one has actually purchased a lot, despite the fact that Terra Firma first announced this boondoggle in 2021.
ETA: The terra firma instagram is also weird. It barely posts and of the Million Dollar Listing cast, the only one who follows it is Josh (not even Matt). The instagrams for the team members are similarly bare bones (actually even less is on them). Oh and I don't know Vegas, but this listing of a terra firma potential home looks awfully like one of the from the episode but it is listed by Compass and is only on the market for $7.8 million, quite a bit lower than the price point that the MDL folks were talking about.
I don't know what is going on, but it's weird.
