I presume you do M2M so that you never have to deal with renewals, can easily terminate problem tenants, and are still able to raise rents if/when appropriate.

Whether they want to store the old one and pay for the re -hookup, or just leave their (presumably) nicer washer/dryer there when they leave and get rid of the old ones now so they have room in their garage, I’d leave up to them.

You have at least two presumably qualified professional opinions now, and you also have discretion on how you choose to act on their advice. 

Oftentimes you don't get enough warning to know your tenant is going to do this until you're already in the 30 day notice period, and the courts move too slowly to help.Because of this tenant, I've decided that from now on I will start talking to my tenants at the 90 day mark to feel out whether or not they want to stay (presuming I want them to stay) and start the discussion about the 30 day process if they seem like they are going to leave.  

I would not presume to 'keep' the contents until at lease a year later.Have you EVER dealt with this issue and gone to court?

So, presumably, the Tenant's liability insurance would have to cover the pit bull. 

Presume the rent is late so send a demand for unpaid rent and late fee along with the 30 day notice of termination now.

And many situations use a combination of the 3 approaches.The single family house (sfr) is real estate, since it is (presumably) permanently attached to the land, etc.

@Natalie SchanneSomething I found interesting was theres a guy selling some single family homes that are rented out to i presume college students, getting over 1%...but even the one that was selling for 325k and renting for $3570/month made me hesitant.

I apologize as I'm not real big on wholesaling... but I would presume there would be difficulties in wholesaling a short sale.
