A little more information. There were a few sales on house sigma for just over 2M late 2020. Were those the thin edge of the wedge and developer called a meeting after amassing a land block? Apparently top house went for 5M. Lots were big (about 2 acres). That one lot probably gets 10+ detached houses or a ton of townhouses.
It would be really interesting to see the strategy. Does first house to sign get 1M over fmv and each subsequent house gets 100K less over fmv? You don't want to stay once your neighbourhood is ruined but you don't get a premium anymore at that point.
It looks like one house is still occupied and has their garbage out for pickup. The rest are empty (and some have started to disappear).
Some of the previous real estate listings talk about how special the development it and how there won't be new ones like it anymore. They were more correct than they realized. Houses are probably ~1990 vintage.
Many had high end stuff (hot tubs, $20k stoves, etc). Does developer let you sell off that stuff? It could probably get negotiated in. They obviously don't want it, just some value from it.
