Most likely you will need to follow the legal procedure outlined for abandonment.

Since I didn't place the first one so I'm not stressing that one, but the second one is a result of me deviating 1/2 an inch from my standard procedure.  

You can toss out what's obvious garbage, and they suggest you store anything that looks like it's of value for a reasonable time, and send the tenant info to come get their stuff by X date.http://www.nolo.com/legal-encyclopedia/handling-te...It looks like different cities and counties in Ohio have different court websites, and without looking closely, it looks possible the procedures may be different depending on where you are, so Google your city or county and "housing court evictions"This one for Cleveland says you need to first serve a 3 day notice to pay or quit, wait 3 business days, then start the eviction through Housing Court.http://clevelandhousingcourt.org/hc_fq_b.html

Accepting cash is a big and risky effort, as there are so many ways an error can occur, through process and procedure, and all caused by the mere fact that cash is involved.  

So, if you are not happy with the unit or the repair procedures you agreed to in the lease, maybe we ought to just terminate the lease. 

It may be worth it to contact an attorney to review the history and have them show you the procedure on how to kick them out. 

As soon as it is late, follow your state's procedures- here we can serve a "Pay or Quit" notice in person to the tenant or any occupant over 18, or we can mail it which is what I do since it means I don't have to track down the tenant.  

I am being extremely proactive and shelling out funds necessary to comply with best-practice procedures in the face of a tenant concern in this area. 

Usually, you have to follow a particular procedure to be able to withhold rent.Probably the easiest and cheapest thing to do, would be to just sue the landlord in small claims court.  

Are there any standard marketing tactics / processes / software / to simplify this procedure?
