There are four separate, recently-sold parcels of real estate on Main Street. Parcel 1 was owned by a Real Estate Investment Trust and was voluntarily conveyed to the City where the property is situated. Parcel 2 was owned by four unmarried brothers and was voluntarily conveyed to their father. Parcel 3 was owned by two corporations, until one corporation recently sold its ownership interest in the property to the other corporation. Parcel 4 was owned by Mr. and Mrs. Kim, but was recently sold to Amanda Lee, Trustee of the Lee Family Revocable Trust. What do all of these buyers have in common?
