For example income limits for 2012 Los Angeles County are median $64,800, for one person the 50% limit is $29,500, 60% limit is $35,460; New York County is median $65,000, 50% is $29,300 and 60% is $35,160. See this HUD site for calculations: http://www.huduser.org/portal/datasets/il.html. The limits for your city may be different so check with the City Housing authority and the management of local housing units. Numerous tenants have complained about rents going up unexpectedly.
