[1] Value-add properties are defined as properties that are either acquired but not stabilized or can be converted to a higher and better use. Acquired properties meeting either of the following two conditions are considered value-add properties: (1) Less than 75% occupied as of the acquisition date (or will be less than 75% occupied within one year of acquisition date based on near term lease roll), or (2) 20% or greater of the acquisition cost will be spent to redevelop the property.
