Cacp, Why do you want to trade, rather than sell? Is there an advantage for you in doing so?
It is much easier to find someone who is willing to buy your condo than it is to find someone who wants to trade their single family home for a 1/1, plus, you will likely need some boot (extra money) to buy the house. There is simple more potential buyers for you unit, than there are people who are willing to trade. In my professional opinion (Realtor), you should try to sell your condo and then purchase a home.
I'm curious to know which condo you are in? Cassine, One Seagrove Place, Beachcrest, etc? If you are Gulf front, you may not need any extra money to purchase a small cottage in Pt Washington, if you are willing to be 3 miles from the beach.
You will find that Realtors are not experienced in trading properties. We are pros at selling properties. In fact, in all of our Florida Association of Realtor forms, there is no contract form for trading properties, so to write a contract as such, we would be wise to hire a lawyer, and still not know all the ends and outs, so we would be stepping outside our job knowledge and expertise, and that should make you a little nervous. Hire us to do what we do best - sell property.
