The additional payment shall include the following elements:

            (1)      The amount, if any, which, when added to the acquisition cost of the dwelling acquired by the Commission, equals the reasonable cost of a comparable replacement dwelling which is a decent, safe, and sanitary dwelling adequate to accommodate the displaced person, reasonably accessible to public services and places of employment and available on the private market.

            (2)      The amount, if any, which will compensate the displaced person for any increased interest costs which he is required to pay for financing the acquisition of any comparable replacement dwelling.

                  (ii)      Actual direct losses of tangible personal property as a result of moving or discontinuing a business or farm operation, but not to exceed an amount equal to the reasonable expenses that would have been required to relocate the property, as determined by the planning board of Montgomery or Prince George's County, whichever is appropriate; and

                  (iii)      Actual reasonable expenses in searching for a replacement business or farm.

            (2)      Any displaced person eligible for payments under paragraph (1) of this subsection who is displaced from a dwelling and who elects to accept the payments authorized by this subsection in lieu of payment authorized by paragraph (1) of this subsection may receive a moving expense allowance, determined according to a schedule established by the Commission, not to exceed $300, and a dislocation allowance of $200.

      (e)      Whenever the acquisition of real property for a program or project undertaken by the Commission will result in the displacement of any person on or after July 1, 1975 the Commission shall refer persons needing advisory services to the appropriate Montgomery or Prince George's County agencies providing relocation advisory services pursuant to the Annotated Code of Maryland, Real Property Article, § 12-206. The agencies upon this referral shall provide relocation advisory services being provided to displaced persons under the relocation advisory services program being administered.
