Do you have a copy of the tenancy agreement which you can attach to a message. I can review the break clause and advise.
3.42 is the break clause. Earliest you can serve notice is Nov to terminate in Jan. This will be without penalty.
5.4 shows address for service. Notice must be in writing and served on the landlord at this address.
You state you have spoken to the landlord. any written agreement that you can vacate early?
The landlord does not have to agree.
You have informed the landlord of alleged criminal activity, it this within your property or within the vicinity, I.e outside/neighbouring property?
What does the landlord want, 2 months rent on top of what you would normally pay? What about the deposit?
Do you still need assistance?
