A reasonable time for purposes of this subsection is presumed to be not later than the seventh day after the date a tenant’s advance payment is received by the landlord, except as provided by Subsection (c).

(c) A reasonable time for purposes of Subsections (a) and (b) is presumed to be not later than 72 hours after the time of receipt of the tenant’s request and any required advance payment if at the time of making the request the tenant informed the landlord that:

(2) an unauthorized entry occurred or was attempted in another unit in the multiunit complex in which the tenant’s dwelling is located during the two months preceding the date of the request; or
(3) a crime of personal violence occurred in the multiunit complex in which the tenant’s dwelling is located during the two months preceding the date of the request.
(d) A landlord may rebut the presumption provided by Subsection (a) or (b) if despite the diligence of the landlord:
(1) the landlord did not know of the tenant’s request, without the fault of the landlord;
(2) materials, labor, or utilities were unavailable; or
(3) a delay was caused by circumstances beyond the landlord’s control, including the illness or death of the landlord or a member of the landlord’s immediate family.
