Condominium Owners Association

Does anyone know of a private, philanthropic organization with the mission of assisting urban condo owners that will help us of the Norfolk Village Condo Assoc make some badly needed repairs to this aging condo complex?  The complex was built during WWII when there was a shortage in copper for plumbing.  Iron pipes were used to build the plumbing system, which is now filling with rust causing low water pressure.  Also, the parking lot security gates need repair.  Many condo units need upgrades to their old heating and air conditioning units. And, several condo units are vacant and need repair so we can attract new "resident owners" to stablize the complex and the overall neighborhood.  Plus, the parking lots and outside community areas need re-surfacing to improve the quality of life.  If anyone can point us in the direction of a private philanthropic organization with the mission of rebuilding and stabilizing urban neighborhoods to make these badly needed repairs this will also impact the whole area.
