Multifamily tenant to tenant issues

[Matthew Conner]

Hi All,

I'm looking for advice on how I should handle some issues that have come up amongst tenants in a triplex. I am the property owner self managing. Unit 1 was an inherited tenant who's rent is paid through hud by the VA (older male disabled veteran and an alcoholic). I renovated and filled units 2 and 3. The Unit 2 tenant (female) has complained of harassment from the Unit 1 tenant on several occasions. I have discussed this with him each time but it continues. Also she has made noise complaints on Unit 3 a few times.

At this time I plan to send all units a letter reminding them to respect leases related to the right to peaceful enjoyment, and a notice to comply or vacate to the Unit 1 tenant. I'm also reaching out to a lawyer to see what my options are. 

As the landlord, should I even be getting involved with these disputes? I feel like I'm playing babysitter when they should be dealing with this themselves or calling the police if necessary.
