HOC is a national leader in developing mixed income housing, a type of Opportunity Housing which includes market rate units and affordable units in the same development. The rents on the market rate units, which may be either moderate or high end luxury rents, subsidize the lower rents on the affordable units. HOC's mixed income portfolio includes The Barclay, The Glen, The Oaks at Four Corners, Montgomery Arms, and Spring Gardens as moderate mixed income developments and Alexander House, Kensington Park, The Metropolitan, Pooks Hill Mid-Rise, Strathmore Court, Timberlawn Crescent, and Westwood Tower as high end mixed income developments.
