Who can forget about Bayswater in Far Rockaway? Was supposed to be Satmar/Chasidish. I think Hurricane Sandy was the last straw, but it did evolve after attracting a more “modern” crowd so it’s not a total failure/loss.
Bloomingburg OTOH was/is a private investment (Satmar came in afterwards) and as a community I thought it’s pretty successful, albeit with rentals. It was complicated with all the legal shenanigans and expenses, but I wouldn’t write it off yet.
