A. In addition to payments otherwise authorized by this chapter, the state agency shall make an additional payment not to exceed $31,000 to any displaced person who is displaced from a dwelling actually owned and occupied by such displaced person for not less than 90 days before the initiation of negotiations for the acquisition of the property. Such additional payment shall include the following elements:
1. The amount, if any, that when added to the acquisition cost of the dwelling acquired by the state agency, equals the reasonable cost of a comparable replacement dwelling;
2. The amount, if any, that will compensate the displaced person for any increased interest costs and other debt service costs that such person is required to pay for financing the acquisition of any comparable replacement dwelling. The amount for any increased interest or debt service costs shall be (i) determined in accordance with the criteria established by the state agency and (ii) paid only if the dwelling acquired by the state agency was encumbered by a bona fide mortgage that was a valid lien on such dwelling for not less than 180 days immediately prior to the initiation of negotiations for the acquisition of such dwelling; and
3. Reasonable expenses incurred by such displaced person for evidence of title, recording fees, and other closing costs incident to the purchase of the comparable replacement dwelling, but not including prepaid expenses.
B. The additional payment authorized by this section shall be made only to such a displaced person who purchases and occupies a decent, safe, and sanitary replacement dwelling not later than the end of the one-year period beginning on the later of (i) the date on which he receives final payment of all costs for the acquired dwelling or (ii) the date on which the state agency obligation under § 25.1-414 is met. However, the state agency may extend such period for good cause. If such period is extended, the payment under this section shall be based on the cost of relocating the person to a comparable replacement dwelling within one year of such date.
