But IRS allows an IRA to be invested in anything except life insurance and collectibles.

I'm sure I could go to some midwest markets or even some more depressed markets in my region and get better pricing, but that's out of my wheelhouse at this point in my life as I have no desire to learn new markets when I'm closer to the end than the beginning. .Sure, obvious but over looked.

And since I would like to go back to it being a STR when some of my life calms down in a year or 2, it doesn't make tons of sense to get rid of it all and then start again!

The owner took the back end profit for his park during the life of the POHs now wants to cash in again.  

And this is a biggee wading through the fake lenders or the Joker brokers that tell you what you want to hear  but cant get the deals funded and you lose the deal and a lot of money.3. with actual PML  private people  usually have very limited funds so cant scale with them.. they can have a life event and just stop doing loans all together..

If I live a busy life and don't have the time or care to invest on my own, but want to put, lets say $200k to work, is a 15% cash flow return reasonable? 

I've been a real estate investor my entire life, doing my first deal as a senior in high school ($5,000 mobile home).

Juggling between work and personal life can be tough, but having a property manager can take some of the pressure off and let you focus on your other priorities

We both run our own businesses but we feel that real estate will help make sure we both maintain our life plans of not needed to work as much any more.
