The objective is to be top-of-mind if and when things change.

It seems it would be in your best interest to further research your true objectives before incurring the fees to transfer the title to an LLC.

I want them to focus on hosts and the guest experience for the actual stay but they sometimes have shiny object syndrome.

If your objective is a given gross profit then you may be forced into doing higher risk, but less competitive and higher profit flips to achieve your goal. 

I have harped on this point continually, but many investors limit themselves and their wealth building because they do not educate themselves on three foundation principles necessary to understand and utilize the most effective wealth and estate building tactics and strategies in real estate.

If it were me, I would think about 3-6 months of principle and interest reserves plus reserves for repairs/maintenance.

But then I get shiny object syndrome and start looking at STR potential in different markets, or maybe trying a BRRRR around here.

I have a great locked in rate and want to use it to my advantage - without doing a traditional sale.Has anyone - or is it possible - to sell my own house utilizing the wrap around mortgage principles?

I would advise you to approve this applicant unless there is a strong, objective reason not to - such as eviction history, a recent criminal conviction, or their income (including all disability income) is less than whatever standard you have used for all of your past tenants.  

You won't have an objective helper or a second set of eyes to catch things.
