Depending on the results, I then decide to move forward with the property or look elsewhere.I hope this helps and good luck on your STR journey!

If they know they can't pay they move and it's over.

I strongly suspect your best move is to roll the TSP to a Traditional IRA and convert the IRA to a Roth, using non-retirement dollars to pay the income tax, even if you have to borrow the tax liability. 

I bought my first duplex in 2022, lived in that for a year, and then a second duplex in 2023 to move into.

If we move to PR and we sell the property after 2 yrs: 1- is the 2 out of 5 yr rule still apply to me in FL? 

Nothing held back for maintenance because the houses they recommend buying are all newly rehabbed, and nothing held back for capital expenses because you should sell them in less than five years and move into multifamily investments so nothing major should break before then. 

My first renter moves in next week, and I was thinking about creating an LLC for the same reasons mentioned by Wale. 

You can still turn this around and move forward to something far better. 

The opposite way of this plan is to get to slow-grow neighborhoods and buy 3-5-8 SFH in cash or 50% hard money in areas like Macon, GA, or Savannah GA, and do BRRRR as well and diversify with 50% long-term rentals and 50% short-term rentals But really, the main idea is to make a smarter move with fewer movements along the way and get it safe as well. 

The loan is issued to an individual or a disregarded single-member LLC, as opposed to loans issued to partnerships or corporations. 3.
