(a) Any tenant who receives or is entitled to receive a notice pursuant to this Subsection, who chooses not to exercise the right to purchase the unit he or she occupies pursuant to division (F) below or who does not purchase another unit or units in the same building or buildings, or in the instance where there is a demolition and new construction, in the newly constructed building, shall, upon vacating said unit within the appropriate notice period as established by division (A) above, be paid by the landlord a relocation expense allowance of $10,000 per housing accommodation; provided, however, that if such housing accommodation is occupied in whole or in part by a disabled, elderly or low or moderate income tenant, the relocation expense allowance shall be $15,000. Such relocation benefits shall be payable within ten days after the date on which the tenant vacates the housing accommodation occupied by him or her; provided, in recognition of the fact that many relocation costs must be paid in whole or in part before a tenant actually moves out, the landlord may upon request of the tenant make payments up to the amount authorized by this Section directly to a moving company, realtor, storage facility or successor landlord (upon receipt of a signed lease, tenancy at will agreement or letter signed by the prospective landlord indicating that they have agreed to rent a particular unit to the tenant as of a date certain with a copy of proof of ownership), or to a utility company or housing voucher administrator in order to satisfy exists arrearages, prior to the date on which they vacate the premises. However, no tenant shall be eligible for such relocation benefits unless all rent due and payable for said unit under the rental agreement or extension of such agreement,
