To have a remedy, you need to frame the problem in legal terms, not emotional ones.
Just because you fear them doesn't make it a problem in the eyes of the law, any more than fearing a person of a different racial group.
The easiest way to solve this problem is for you to move.
The next easiest thing is to increase your understanding of them so you can find if your fear is real or baseless.
If it is real, call the police.
The best chance you and your landlord have of evicting the gang members (I am assuming you are in the US here) is to find evidence they are dealing drugs on the property.
If they are doing that, not only can the landlord evict them, he MUST evict them.
He cannot ignore drug dealing.
Any criminal activity is grounds for eviction but, for whatever reason, drug dealing is afforded special status in the eyes of the law.
I know of no law that forbids renting to a felon, or a gang member.Another PerspectiveA landlord has the responsibility to provide tenants with a safe and healthy environment. Renting units to known gang members who then cause damages, harm or loss to the other tenants may create some liability for the landlord. If that is the case you should consult with an attorney or with a landlord-tenant agency in your town who can review your situation and explain your options, if any.
Your landlord , end of discussion.
What a landlord verifies is completely up to the landlord
yes.
A property owner who is renting the property out to people to live in.
A person renting out a place may be the owner, an agent, a landlady, a landlord, or a tenant subletting space.
Yes. The relationship between the landlord and bank has nothing to do with the tenant.
In some states, the lease survives the sale; in others, it does not. Regardless, the landlord certainly has the right to sell.
No.
No. This is an act of god. You should notify your car insurance.
You tell the health department.
A prudent landlord would.
