A good deal? I don't think so. The place is very pretty but...
1. It's not a good deal for Belizeans who care about their eco system because the number of humans this project is proposing to put on the site cannot be sustained in that fragile environment right on the reef.
2. It's not a good deal for the developer because he will undoubtedly go bankrupt...people who try to build levittowns in the tropics always do....
3. It's not a good deal for the buyer who wants to live in a tropical levittown because most people won't build on their property, and that includes most of the "services" that are being promised. So the buyer, lacking the desire to build a sustainable, private, living environment from scratch, will just let the property sit there 'cause he doesn't want to go it alone.
4. It's not a good deal for the person who wants personal freedom, because this kind of levittown usually has a bunch of rules (like the one about "no pets that purportedly is among those set for this project.) Do you want somebody running your life to that degree?
5. It MAY be a good deal for the person who really does NOT want to live in levittown and is willing to go it alone. Of course, there will be a lot of construction litter and started-but-abandoned construction debris lying about. But if you want to rough it on a tropical island, why not buy some land all for yourself and just do it?
That's my opinion...of course I could be wrong.
