In this way, I have leverage to enforce my lease because who wants to be evicted over a modest damage bill. 

@Timothy Burns, I would contact code enforcement.

One of the biggest problems with inherited tenants (besides being way under market) is that often they either don't have a lease or it wasn't enforced.

They will contest the debt and most likely you will end up needing a Judgement which you then hope to enforce later (good luck).The main leverage you have in your desired scenario is Posting negative item in tenants Credit Report and hope they care.

You can ask them to have quiet hours but pretty impossible to enforce.

Sue, you have enforcement policies that don't change regardless of the tenant.

If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

Tankless are a PITA.Tankless require descaling up to annually depending on water and if you fail to descale as needed the warranty is not enforceable.  

Tell them you purchased their father's property at the tax auction, and they will have to surrender possession of the property or you will sue all of them to enforce your rights.

my understanding that there is rent control as well and can not increase rents more than 7% a year for the same tenant.Just trying to see if there is a possibility to enter this market at this timeTIA Hi Lydia,Currently Michigan legislature states  "a local governmental unit shall not enact, maintain, or enforce an ordinance or resolution that would have the effect of controlling the amount of rent charged for leasing private residential property."
