Just Looking, Philadelphia, PA
It depends on if by "subsidized" you mean rental or homeownership. The Ludlow development referenced below contains a phase of each. The rental is affordable to people making 20-50% of Philadelphia area median income. There are pretty stringent credit and criminal background checks, so I wouldn't necessarily worry about riff raff, but this is not a population that would necessarily support high-end retail or upscale restaurants. The homeownership phase units however sold for between $160-$180k to people earning up to 80% of median income. For the most part, buyers were young families or single professionals who just barely got in under the income cap and recognized a great real estate opportunity. These homeowners will (hopefully) gain in earning power in the coming years and will have a significantly greater positive impact on the community.
