Social aspects of RE are not limited to low income tenants, far from it.Look too, for the National Association of Housing Officials and Redevelopment (NAHRO).Here are some organizations or other folks that deal in RE within their realm.Office of AgingAssisted LivingAdvocate Organizations for the blind, handicap, children, etc.City P&Z OfficesDept. of Defense, especially the Corps Of EngineersDept. of EducationDept. of Health and Human ServicesEconomic Development identifies blighted areas and funds redevelopment.HUD/USDA have social and economic skills educationHOA organizationsLook to your local United Way, they are often the gatekeepers for funding going to community service organizations and they will know non-profit housing entities that serve an area.Developers base growth from social impact studies, demographics are the social and economic movement of populations.

If I need x in cash flow by 20xx, then I'll need y units making $z.00 per month post tax, I need to buy 'n' properties per year on this schedule( which doesn't have to be linear). 

Some markets/states do okay during a recession, some are God awful.That said, you still have to buy not like you're in an upward swing, but based on flat at best or even anticipating a small downturn where if I buy at X, rehab costs Y, the least I can make is Z if everything goes to hell in a handbasket in the next three months.  

Have a look a Z Inspector.

This typically covers paint and whatever touch up I might need for x,y,z reasons.

All you have is a letter giving general terms subject to X,Y,Z happening.There is Equifax, Experian, and Transunion.

Assuming the fed approves X dollars to be distributed to Y people: Does adding Z eligible immigrants increase the X dollars approved?
