I'm in Orlando and am on the board for CFRI, the local chapter of the National REIA.

Labor, materials, insurance, interest, local property taxes - yes.

If not you, where could I get this type of mentoring and learning in my local area?

Pompano is trying to put a lot of money in the area by renovating local parks and community centers, but the gentrification of the area is still in the beginning stages.

I’m a local STR Property Manager in the Mariposa/Oakhurst Community.

It looks like they are offering a lease as well but I would highly recommend paying a local real estate attorney for a lease.

You may want to consider a local bank for more attractive terms. 

I'd appreciate some insight from some local investors.

In the future, a) get a super detailed Scope Of Work and ironclad Contract. b) Do not pay more money as a progress payment than the amount of work that has been performed, that way you are never ahead of the Contr or vice versa.Your options (depending on how much he owes you) are Small Claims Court, the State Registrar of Contrs, and possibly the local DAs office or State AG if the amount is higher ($50k ish)Good luck, let us know what happens.

If no response from the tenant within their legally allowed time, file in your local l/t court.
