Right now I find that I can easily find properties but have been finding difficulty showing proof of funds making people  willing to  wholesale their properties.

The student requests no proof of the mentor's success in the industry but instead gets easily sold on the rainbows and pixie dust.

I see no rationale where they deserve an STR permit over a STRs that provided proof of paying transit occupancy tax and being good hosts (few complaints/issues, etc).  

From the outside, it will look like a dark room, and from the inside, you'll have a fresh slate to install your shower surround (just make sure you don't screw through the plywood and shatter the glass behind it though!).

I was able to STR our first home after moving and it has been a great success.How were you able to use STR income as proof if income for the 2nd and 3rd property mortgages?

Nothing is bullet proof, but a good maintenance process helps.

My question is, do I bite the bullet and add mini splits?

Why can't you start with some smaller residential or small multifamily commercial properties to get your feet wet, show proof of concept and possibly try to take on larger deals.Or possibly find a local syndication group and become an employee under them learning the trade and finding a mentor in the space.
