How to end my lease early?

My question is this:
 
Are you more interested in resolving the problems you stated above?
(OR)
 
Are you looking for ways to break your lease early?
 
I can see how you might be frustrated with your apartment manager not resolving some of the problems  you listed, however, I’m not seeing anything too major that would allow you to break your agreement.
 
Why not talk to your landlord about what your options are.  Don’t be surprised if your apt manager isn’t willing allow you out of your lease.  It will be much easier to make arrangements with your manager to fix your rent problems versus ending your lease.

I don’t think you have a case to end your lease early.  The manager hasn’t violated anything.  You even said that the manager is nice and unaware of the problems.  It almost sounds like regular apartment life.  Many of the things you mention are constant battles when living in high density housing.

The rent issues you’ve mentioned:  Doggie poop, Noise, Smoke Smell, and violation of parking rules are not big enough problems to merit an early lease termination without penalty.   Have you talked to management about the new job for your husband?  Talk to them to see what they are willing to work out for you.  You might be able to find another tenant that can take over your lease.  Time to look for a solution instead of trying to put the burden completely on the apartment complex.  You are the one needing to move because of a new job, not because of problems around the complex.  Its almost tasteless to come up with your list of problems in hopes that it will be a reason for you to end the agreement you made with your landlord.  I think you’ll get further by being reasonable and responsible.

Actually my husband and I like our apt., we plan to stay a while, and here is an update: The manager has taken steps to remove undesirable tenants and increased the maintenance, things are better now.
