No, I think the problem must be corruption, either legalized where a variety of non profits add administrative overhead, or downright illegal. For example about a mile from the first project mentioned in this article are luxury town homes for sale, that come with features such as granite counter tops, garages and solar panels. The developer is selling these luxury homes for about the same price as the affordable housing costs. I imagine the developer is also making some kind of profit. If the price was just land, you’d expect that a luxury unit would cost more than affordable unit, not the same.
