I would contact a buyer's agent; we used one when we purchased our land here. She was very knowledgeable about the area - she's lived her whole life here. The seller pays commission, not you, and a buyer's agent is better than going to an agency like ReMax or Century 21 - those agents work primarily for the sellers, not the buyers. They have dual loyalties, whereas a buyer's agent is not allowed to accept listings. She's 100% for the purchaser.
We loved our agent! She lives very near WDW, so knows all about this part of Orlando. If you'd like her information, PM me - I don't want to post it on here, but she really was fantastic and made the whole experience easy. I'm sure she'd talk to you about the different neighborhoods; for us, she got together a sheet of properties like what we were looking for, so that we had choices. She personalized it, though, so that all of our choices showed acreage and were in a certain area & price range. We did our purchase from long distance, and she made the whole process incredibly easy, even lining up for us a surveyor, environmental engineer, etc.
Cheers!
