Section 301(6) of the Uniform Act limits what an Agency may charge when a former owner or previous occupant of a property is permitted to rent the property for a short term or when occupancy is subject to termination by the Agency on short notice. Such rent may not exceed “the fair rental value of the property to a short-term occupier.” Generally, the Agency's right to terminate occupancy on short notice (whether or not the renter also has that right) supports the establishment of a lesser rental than might be found in a longer, fixed-term situation.
