I would also look to "stage" it with your furniture by minimizing and decluttering.

I mostly want to understand how do I go about figuring out the demand / vacancy rates for MTR before investing in furniture etc on my property.

You have considerably less wall space, and trying to fill furniture into that one big space is often awkward resulting in a lot of wasted space that does not really do anything.And while these open floorplans are often promoted as "family friendly" I have come to the conclusion that they are a double edged sword in that respect.

I provide leather sofa and chair, end tables. 

Furniture is already there.

This will also help you be organized when completing taxes and writing off any potential expenses like furniture, utilities, repairs etc. that come with the rental business. 

If the rental is in town, maybe start looking on Craigslist, FB Marketplace and OfferUP for quality used furniture to have as backups?

I'm sure when you get there to do your inspection you'll find that he left his keys on the kitchen counter, took most of his clothes and left behind nothing but trash and old furniture.

Normal home owners insurance covers the house, liability, a bunch of miscellaneous items, and all your stuff (furniture, clothing, appliances, etc etc).
