If you don’t do anything, at the end of the existing lease term, disposition is at the discretion of the City. They will decide whether they wish to extend your lease, and for how long, and the renewal rent will be subject to arbitration based on the provisions of the existing lease. There is no change there. Or, the City may opt not to extend, and your lease will then expire at which point your unit may become a rental unit in the hands of the City.
