And how has that changed with your experience level?

@cWill Gaston has alot of college rentals he may have some experience.

Now ideally I could STR all of the units individually but given this is my first foray into STR, I'd like to set up a couple of these units as LTR and try to AirBnB/Vrbo one of them.

Now, for those specializing in this with the experience of 150 transactions behind them, they probably have the knowledge, experience to make it work and to limit the problems of it ends up in court.  

I’m in the process of switching several of my buildings over to individually metered propane heaters so the tenants will become responsible for their own heat costs and more accountable in their waste of resources.

From my experience I would avoid it as a seller unless I was getting a large down payment, a larger purchase price, or a higher than market interest rate. 

I have previous entrepreneurial experience.

You don't need to know everything to get started; you need a foundation to build on and the rest will come through experience and then refining your education.You can build a basic understanding of investing in 3-6 months.

The problem with someone's experience (and this is not just for STR) is the experience is hard to duplicate.

They want to sell all of them at once, and not piece meal them out individually, so they are asking for less than market value.The offer is 6 homes 5 of which currently have renters, for $400,000.
