It is hard to get in and a great deal if you are lucky enough to qualify. Only a very few of the poor hit this jackpot of fairly high quality housing for perhaps half off the free market rent. You’ll likely keep your income low so as to continue to get this lucky gift from your government. Because the government pays about twice the market price to buy or build these units, the taxpayer gets a raw deal, but politicians are able to claim they did something about affordable housing, so everybody’s happy, except anyone who looks deeply at the true costs and true benefits.
