Last summer, University of Wisconsin-Madison senior Kiera Wiatrak and her roommate found themselves in a common predicament: The lease on their downtown apartment ended Aug. 14, but their new least didnâ??t start until Aug. 15.Fortunately, the residents of Wiatrakâ??s new apartment had moved out early, so apartment managers told Wiatrak she and her roommate could move in early if they were willing to pay $40 a night before their lease began.
