I've had business and conducted hundreds of sales transactions and find it very underhanded.

Quote from @Emily Gowen: I only recommend investors sell when they can move the money to a better-performing investment or when the sale moves them closer to a specific goal.

You are essentially doing a partial sale of your home.

Right now, the best offers around me are for some 1.3-4 million, that only generated around 100k per year gross, so there would be a high chance of not cash flowing, and paying money, especially with a commercial loan (these buildings have more than 4 units).I was thinking that although the rental itself does not generate money, I would be able to deduct the mortgage interest, and depreciation from my personal w2 income and would be net positive.

It's a more affordable market and lower property taxes, so you may actually have a chance to cash flow.

Send a notice: The landlord can post a notice in a visible place and send a notice by mail to the tenant's last known addressRemove belongings: The landlord can remove the tenant's belongings and store themRecover costs: The landlord can recover the costs of moving and storage from the tenantSell belongings: If the tenant doesn't claim their belongings, the landlord can sell them at a public sale(End)Please only communicate with the tenants - all of them - in written form only so it can be used in any collection/court engagement. 

There's a good chance the issue(s) you face has already been discussed and answered.Ask questions in the appropriate forum.

Chances are they are paying others who are not as accommodating as you (amazing how people will make those car payments while jeopardizing their homes) - and it's time for them to move on to housing they can afford and to a tenant that does not require you to subsidize them.  

They are holding the proceeds from my sale and I am planning to buy a couple of DSTs shortly.
