My mom is actually a property manager, and anytime a tenent disagrees with the pooing fee, she always tells them to try and catch the other person in the act, and take a photo, now you say your afraid of this man, i would use my camera phone and act like your trying to get service or texting! As far as the flat tire, and things like that, photos, they never lie!!!!! If your manager in the office is not acting like a manager should, find out the management company that manages the property and write an email or letter to the home office stating your issues just like you did on here, WITH the photos you took of the other peoples dogs pooing, and the maintence guys car. Also explain to them that you are afraid to live next door to the maintence man because he has keys to your apartment and youd like to be swtiched to another building, or let out of your lease.
Also, a lot of people that want out of your lease, put it up for rent on Craigslist.com and sometimes there is a lease transfer fee to put it in the other persons name, but its no where near the same price as paying a break lease fee, mine was 100.00 when i re rented mine. some are cheaper. Thats a good way to get out of your lease legally and it doesnt make you look bad at all.
Go into the office and ask them what the lease transfer fee is if you find someone to rent your apartment. Also, try home office first, sometimes that can get you further!
