(2) Court-appointed receivers. A receiver who is appointed by a court of competent jurisdiction to receive rent for the use or occupation of a housing accommodation shall not, in the absence of collusion or any relationship between such receiver and any owner or other receiver, be liable for excess rent collected by any owner or other receiver, where records sufficient to establish the fair market rent have not been made available to such receiver.
(e) In determining fair market rent appeals, filed pursuant to paragraph (a)(1) of this section, consideration shall be given to the applicable guidelines promulgated for such purposes by the Rent Guidelines Board and to rents generally prevailing for housing accommodations in buildings located in the same area as the housing accommodation involved. In addition, consideration of the rental history of the subject housing accommodation for the period prior to the four-year period preceding the filing of the fair market rent appeal is precluded. The rents for these comparable housing accommodations may be considered where such rents are:
(1) unchallenged rents in effect for housing accommodations subject to this Code on the date the tenant filing the appeal took occupancy; or
(2) at the owner's option, market rents in effect for other comparable housing accommodations on the date the tenant filing the appeal took occupancy, as submitted by the owner.
