K, it doesn't seem to me that any of these answers were practical in your situation. List them with a Realtor, set a low price, hope you bought right, huge inventory, hold them for a year... blah, blah, blah. The reality is the Florida real estate market is crap, and land in a crap market is even crappier (excuse the french).
You probably need money NOW, so you will have to target investors, not retail buyers or builders. Consider selling an option on your land to an investor who is bullish on the next couple years in the Florida market. Basically, selling an option is selling the right to buy your land at a set price, within a specified period of time. They are not obligated to buy, but can within the time period (they are betting the prices will increase over time). You get the "option fee" up front, in cash, and if they buy in the future, you're cashed out, if they don't the option expires, and you still keep the fee and the property (and could do it again). $$ have to be in line with values, but this strategy puts needed money in your pocket.
Most 1-4 Family P&S contracts have sections for option periods and you can use that. Title company can help you with the rest.
Good luck. In this market it's time to get creative!
