I am very familiar with this area and have sold parcels there. I am not asking anyone to call me, as most agents tend to do. But my contact information is readily found and I don't ever mind answering questions.
You land is directly south of the 8.5 Square Mile Area (so named by the Army Corps of Engineers in their Everglades Restoration Modified Water Deliveries Project). This area is now called Las Palmas by its residents. Within the boundaries of the 8.5 SMA as well as outside of it, the Department of Environmental Resources Management (DERM) has been fining property owners for not using the property in a way consistent with it's zoning. They claim much of the land is classified as wetlands and cannot be farmed without proper (and very expensive) permitting. If it cannot be farmed, who is going to rent it? Most folks who rent these types of land do so to do some sort of farming. The situation is complicated and has continued for years, without a resolution.
The community is in an uproar over the excessive fines by DERM and I've attended protests to bring attention to the unfair and excessive fines by DERM. Some folks have homes on these properties and claim they've had to mortgage their homes in order to pay these fines.
There is a very active resident in the area who has employed the services of a law firm to fight for her rights regarding this. Her efforts would help her neighbors as well so she has sought their support. She can be reached by going to the first link I am posting below. I am also including a few other links in case you want to read up on this. It's complicated and most Miami-Dade residents are unaware it's taking place. If you go to Google and search "8.5 Square Mile Area" you will come up with more information than you would care to read.
But everything has a price. Yes, your land can be sold. A realtor who is active in the area can give you an idea of its value. As for renting, that's more complicated. Of course you can rent it. But your tenant will be limited in what they can do on the land and you should make them aware of the limitations BEFORE they rent so they don't come back to you later, upset that DERM came in and fined them for whatever they are doing on the property.
Best of luck to you.
