This is what I am trying to do as well and it is pretty difficult in the FL markets that I have looked into. If anyone here has any suggestions for other places in FL, let me know.
Dropping this too in case you or anyone is interested.
I have a friend who is selling a STR in Galveston Texas $650K, it did $90K gross with 5 weeks off due to new pool construction in October/Nov, so I guess the aim would be $100-$120K gross this next year since it has a very nice pool now. Direct to seller.
I also have a friend who is looking to sell a $200K gross property (2021 and 2022 numbers, expected to hit it again in 2023) in Tulum for $1.1M. They are upgrading it to be a 5 bed instead of a 4 bed. Asking for $250K down and they're open to seller finance the rest if you are unable to find good financing options. They live there and would help teach the new owners everything and manage for 10% if needed.
Feel free to message me for more details on either option
