If the property management company has not had any contact with you about the rental that you could not occupy due to the absence of water for eight months, you can presume that you are not going to be pressured about breaching any lease.If you have requested the deposit and partial rental return months ago, you need to call the property management company right away about the situation and follow up on the subject with a written letter requesting their return by a stated date.If the deposit and partial rent are not returned to you by the time requested, your option would be to file a small claims court action against the property management company and the landlord for their return.Good luck.
