I collected some contacts, asked a lot of questions, watched a lot of youtube. 

@Caleb FolseCozy is great for rent collection.

well, you can wait to see what your lender says or pro-actively collect some soil samples from around the inactive tank.  

Those are usually pretty current as they collect payments from homeowners throughout the year.

Hasn't your company been collecting escrow for real estate taxes and home owners insurance for the past 10-11 months?

With what's happening they are the most stabilized return before collections.

Or maybe try to "psyche" the tenants out into leaving by getting them served again and sending a tersely-worded letter from a lawyer that makes them think that a court hearing/eviction is imminent.

Study what other property managers are doing, apply their fee structure to your scenario, and then tweak it to make it work.You'll soon find he can't do well with less than 8 - 10% of rent income collected.

In the process of doing all this I also have a handyman that has been managing everything from fixing leaky toilets, repairing roofs, helping locked out tenants, collecting rents, handling evictions, and helping with leases where needed.  

How do you collect a security deposit for tenants that currently live in one unit of a multi-family I'm scheduled to close on in two weeks?
