Advice for dealing with Tenant issues

[Casey Roloff]

Hi!

I'm in need of some advice for dealing with two problem tenants.  I recently purchased a 4-plex in Arizona and inherited 3 of the 4 tenants (2 out of 3 on Section 8).  At closing, I immediately accepted a 4th tenant who is with a subsidized rehabilitation housing program called Achieve.  Each tenant signed a one year lease in February, 2017.

Within the last two months I've screened multiple phone calls from the tenants in Units 4 & 2 complaining about the tenant in Unit 3 (The tenant that I accepted).  Complaints ranging from loud music, door slamming at all hours of the day and night, calling the other tenants horrible names, etc...

Today I received a phone call from the tenant in Unit 4 saying that he believes the tenant in Unit 3 is "cooking dope" because they've been smelling something horrible in the middle of the night.  The tenant states that he is concerned for the safety of his two little ones.

I've notified each complaining tenant that they need to call the police if they suspect illegal activity and have talked to the accused tenant several times about correcting the issues until now with the drug related accusations.

My wife recommended that we start a formal complaint process via mail which will eliminate the phone calls (and drama) and assist with documenting the complaints. 

My questions are ... What advice do you have for dealing with future tenant complaints?  What do I do about the drug related accusations? 

Thank you in advance!
