Ask a landlord-tenant lawyer and get answers ASAP
Hello and thank you for the opportunity to assist you. My name is ***** ***** I will do my very best to answer your legal questions.
To clarify, are you now up to date on rent?
If you are always up to date on rent, and your landlord gave you a notice to vacate due to late rent, then clearly there is a disconnect. You could take the landlord up on the offer to vacate, and thus terminate the lease as you suggested. If the landlord fails to fix anything, then you could indeed sue him for over-payment of rent. The argument is that the apartment was not worth what you were paying for it because the landlord failed in his basic duties to make ordinary repairs. Unfortunately, it's unlikely that you'd win a lawsuit for slander or harassment, however (at least I don't see that you'd win based on the facts few that you shared). Finally, the fact that others in the building were treated better upon moving in is not ordinarily something that you can sue over, unless the reason for your poor treatment is based on something like race, religion, gender, disability, etc. If so, then that would be illegal discrimination, and you would surely have a case against the landlord.
Does that answer your question? Please let me know if you need clarification, as I am happy to continue helping you until you are satisfied.
