The answer is probably not, but you can have the landlord arrested, or at least file charges against the person. To break the lease, you will probably have to sue in court.
A contract of lease cannot be broken if the tenant has been threatened by his neighbor unless the landlord permits. A tenant can talk the matter over with his landlord.
This depends on the laws of the state where the property is located. In Massachusetts, for instance, the tenant could be evicted with a 48-hour notice, if the landlord has a police report stating that the police found an illegal firearm in the unit.
why won't the police help me after my landlord sent someone to break into my home
Check your laws.
Yes, you can break your lease if your landlord refuses to fix things, as long as this is specified in the lease. Your landlord is liable for keeping the home in working order and safe. Contact an attorney to help you with the lease.
Yes
No - that's not a breach by the landlord.
a landlord may not EVER break/violate a lease. [unless the tenant wishes it so]
As a tenant, if the landlord wishes to break their own lease, you have the right to seek damages just as they would if you had broken your lease. The usual outcome for a landlord to break a lease is that the landlord forfeits any right to retain the security deposit.
No. That is not a breach by the landlord.
In order to know if your landlord broke any laws one would need to know more details about the offense committed by the landlord and the state in which you reside.
If you have this clause in writing in your lease agreement and the landlord doesn't follow through then you have cause to break the agreement.
