Sorry to hear things are not working out here as hoped, I admit I have only been here 2Â½ years, and it was a lot different here than in Central Florida.
Bruce has really covered all the major issues you could face by selling so soon after purchasing. I would like to add one other thing you may consider. Lantana has a very good rental demand, and good occupancy ratio. I myself am not a fan of renting out what was a primary residence, but drastic conditions can call for drastic measures. Many times you can pad the rent amount enough to cover a mortgage, plus get security deposits for pets, or if it has a pool.
Which ever route you choose good luck, and feel free to contact me with any questions, or concerns.
