Would the 9-year balloon concern you, knowing you'd need to refinance or pay off the balance at potentially higher market rates in the future?

The higher the cap rate, the more risk involved in the building. 

My main concern is the interest rates being so high now as to whether what I'm hoping to achieve is really even possible. 

Reason is a Heloc generally carries a higher rate on a shorter term and "Can Never" be used as an "Asset, or for PITI reserves" which are both required when you buy an investment property. 

I am seeing interest rates start in the mid 6% range for foreign nationals here in Florida.

New inventory and relisting rates have actually declined month over month which is allowing to pricing to remain elevated.

What about rate and term refinancing?

You would end up saving the higher interest rate on the HELOC as well as closing costs.

@Tom Rairdon If you’ve owned your short-term rental (STR) for over a year, it likely qualifies for long-term capital gains (LTCG) treatment, taxed at lower rates (0%-20%) compared to your 33% ordinary income bracket.
