Some folks have already given good advice, and I want to add a quick tip for how to get data on potential STR properties.

Call a different number you found online associated with the same company, etc. 

Welcome to the community and be ready for a huge amount of information at your finger tips.

Maybe it's in my head but sometimes there are two LVP advertised online with the same thickness, but in real life one feels obviously thinner/thicker.

I came across one of these loan agreements online somewhere a few months ago, can't recall where I found it but it was clear in reading the loan agreement there was no language referencing the loan actually encumbering real property, it was just an unsecured loan.  

One tenant is behind on rent and has still not paid December rent.I’m seeing mixed things online but looks like I have to file something by the 31st?

Look for your states offer to purchase contract online or contact a realtor to get a blank copy. review the agreement to be sure assignment is not expressly excluded. if there is nothing excluding assignment from the contract then writing the words "/And or Assigns" after the name or company's name on the buyer's line should be sufficient.Good luck!

If I am self managing my portfolio, what do I need to check/confirm, and what easily available tools are at my disposal (online, other) to help me do this? 

that is totally unrealistic return.. your going to blow your 15k and be very dissappointed why would they give you 50k profit deals just to sell you a 15k course.. ???
