One dude I know trades antique firearms online for a living while (currently) renting out in the middle of rural nowhere.

Meaning he is probably comfortable with firearms and is expressing his 2nd amendment rights.

Such acts and omissions include, but are not limited to, the following:(1) Manufacture, cultivation, importation, transportation, possession, furnishing, administering, or use of illegal drugs in the dwelling unit or in the common areas.(2) Illegal use, manufacture, importation, possession, furnishing, or discharging of a firearm or firearm ammunition on the premises of the rental property, except for the use or discharge of a firearm or firearm ammunition in cases of self-defense, defense of a third party, or as permissible in Section 13A-3-23.(3) Criminal assault of a tenant or guest on the premises of the rental property, except in cases of self-defense, defense of a third party, or as permissible in Section 13A-3-23.(4) Any breach involving substantially the same acts or omissions as a breach for which a notice to terminate has previously been provided for by the landlord and cured by the tenant, if the second breach occurs within six months of the first breach.

I'm looking to send a 'notice to quit' to a tenant that's been in conflict with lease terms on several different points (unlawful possession of firearms, not maintaining clean unit, disturbing other tenants right to quiet enjoyment of property, etc).

The tenant allows a violation of MN Stat. 504B.171 Subdivision 1 (allowing controlled substances, prostitution, unlawful use/possession of firearm, stolen property on the premises).The tenant has materially violated the lease, other than nonpayment of rent.

Originally posted by @Jake Roberts:I know he's also said a lot of really dumb and controversial things, like not allowing tenants to have firearms.

Do you provide them with a firearm for security?

My reaction as a LL would really depend on the details and so far we have not much to go on except a firearm was discharged by someone and an arrest was made.

@Anthony GaydenNext to be addressed is that pesky criminal background check when you go to buy a firearm.

They ran out and bought firearms and ammunition!
