Is this legal in South Florida?

[Brian Garrett]

An investor here on BP messaged me about his business model and it piqued my interest about the legalities.

He's renting places and then turning them into Airbnb to cover the monthly rent and then pocketing the profits leftover.

So essentially he's getting cash flow without owning the properties/units.  Is this legal to do in South Florida?

I don't like the strategy personally as you lose out on the equity, appreciation and tax benefits of REI but I'm just curious.
