If you can lever up 4x to 5x on a $2M property that doubles in value every 10-12 years, who cares about landlord-tenant laws?

Therefore you are taking bad information and then interpreting it incorrectly which is double trouble. 

You also have to know whether it will be an assignment or a double closing.

I was shocked to see that she doubled her price in a year. 

Currently I’m operating it as a STR, but I need a new cleaner and the quotes I’m getting are in some cases double my nightly rate, and the amount it grosses is only slightly more than what it will do as a LTR.

If you set up a "checkbook LLC" for your SDIRA, then I believe (check first with your custodian and/or attorney) that you would be able to invest directly as the manager of your LLC (using the LLC's account), without going through your custodian.On the other hand, that ability to quickly invest can be a double edged sword, since I think the delay can be a good thing (it forces me to think more carefully about the syndication and take the time to make sure it's a good investment for my SDIRA).

Just recognize the rate would most likely be in the double digits, especially if the portfolio loan is not in first position.
