Some in Fairfax Public Housing Make Six Figures - washingtonpost.com
The median new home price in Fairfax County is $960,000, according to this article. And of course nearly all the new housing is in CIDs.

Hundreds of families living in housing subsidized by Fairfax County taxpayers exceed income caps designed to ensure that only the neediest receive assistance, a review of county records shows. In the most extreme cases, Fairfax is underwriting rents for families making well into six figures: One household getting help makes more than $216,000 a year; another, $184,000. Dozens of others -- making $60,000, $70,000, $90,000 -- exceed eligibility caps. And they do so with the tacit approval of county housing administrators, who do little to encourage occupants to move on when their fortunes improve.
