Effects of Housing Authority, Neighborhood Assoc's, and Section 8

[Sam Watson]

Someone please help me with a conceptual analysis of the impact of affordable housing properties on nearby property values/rent potential:

Suppose I'm interested in a 4plex property whose location seems to be just outside of a growth path along a primary artery in an urban market. After analyzing the particular pocket of the submarket, I notice there are properties owned by a neighborhood association and by a housing authority (say, within 0.5 miles of the subject property). What are the effects of these agencies' ownership of the nearby properties on the value and rent potential of the subject property?

In other words, if nearby rents are increasing and moving into the path of a certain property, would the nearby housing authority/ neighborhood association refuse to increase rents in accordance with the market and block growth? Would they refuse to sell the properties to redevelopment firms for value add or to be willing to relocate to a location more suited for the income/work proximity of its tenants? Or are these agencies very adamant about staying on their properties and making them stay affordable, despite the deadweight loss produced by prohibiting value creation and loss of potential tax revenue?

Will my subject property likely not yield the returns I expect due to neighboring affordable housing agencies pushing against market forces? Am I looking at this the right way?
