If, as a result of the unlawful discriminatory acts or practices of the respondent, the prevailing complainant was required, in order to satisfy his or her housing or commercial space needs, to pay rent in excess of that which he or she would have paid but for the unlawful discrimination, and upon proof of being so required, the prevailing complainant shall be entitled to damages equal to the amount actually paid in excess over the rent for a comparable space during the period of violation, or during the period for which the prevailing complainant was obligated by lease to pay rent to a third party, whichever is greater; provided that if the lease period exceeds the period of violation by more than two (2) years, the damages shall be limited to two (2) years from the end of the period of violation.
If, as a result of the unlawful discriminatory acts or practices of the respondent, the prevailing complainant suffered a demonstrable loss of income as a result of delays occasioned in the obtaining of commercial space in which to conduct his or her business, the prevailing complaint shall be entitled to damages equal to such lost income as can be reasonably proved.
If, as a result of the unlawful discriminatory acts or practices of the respondent, the prevailing complaint was required to pay a purchase price for housing or commercial property in excess of prices contemporaneously paid for similar housing or commercial property in the same or similar area or neighborhood by persons not unlawfully discriminated against, the prevailing complaint shall be entitled to damages equal to the excess price actually paid.
If, as a result of the unlawful discriminatory acts or practices of the respondent, the prevailing complainant was prohibited from making an offer to purchase housing or commercial property, or if an offer of the prevailing complainant to purchase housing or commercial property was rejected for an equal or lower offer from another purchaser; the prevailing complainant shall be entitled to damages equal to the difference between his or her actual or intended offer and the actual sales price of the housing or commercial property to the other purchaser.
If the housing or commercial property for which the prevailing complainant intended to make an offer, or for which his or her offer was unlawfully rejected, is not eventually sold; or if the eventual sales price is equal to or above his or her offer; the complainant shall not be entitled to damages unless he or she was required to pay more than his or her original or intended offer for similar housing or commercial property, in which event he or she shall be entitled to damages equal to the excess of the amount paid for similar housing or commercial property over the original or intended offer.
If, as a result of the unlawful discriminatory acts or practices of the respondent, the prevailing complainant or his or her family or his or her business were required to move or store all or part of his, her, or its personal property, or to secure temporary quarters for his or her family, the prevailing complainant shall be entitled to reimbursement of such moving or storage expenses or expenses for temporary quarters.
