In general we require a one-year lease for all tenants. We make occasional exceptions depending on occupancy levels, but only if the applicant can prove they are in town for only a short while. For example, we have a few project managers for local construction jobs on short-term leases during the construction.
Nevertheless, we do have a favorable "early termination" policy if you need to leave unexpectedly. If you leave early, we have a duty to try our best to rent out your apartment. If we do rent your apartment, you are only responsible for the time it went vacant. However, if you wish to avoid that risk and obtain a clear closure, you can give a 60-day notice and agree to pay an early termination fee of one month additional rent. Even if you have several months left on your lease, this fee will allow you to break the lease.
