Rent plus,groceries and most bills, if that is at least 50% of income (rent alone is typically a third of income) on 80k/yr that is 40k * 100k = 4B. Even with just 1500/mo rent that is 1.8B gross/yr and 18B in 10 years if net profit is only a 3rd of that (assuming it won't collect taxes like cities!) it will be 6B/10y. My point is, to recover costs in 10 years, you need to make it at a cost of 60k/unit which seems low but I am hoping economy of scale would make things cheaper. Like, it would make sense to have your own factories close by just for the concrete,wiring,etc... but at least with 100k/unit cost(10B) it should still be possible and the recovery time isn't too bad given mortgages go 30+ years. And picking a good location can guarantee occupancy.
