The best thing is to go by price, then do a search of the entire market to see what's out there.

I'm in agreement with the previous responses. You have a wide variety of land/lots to choose from. If you are looking for something residential, for 5 acres you may have to go a bit to the outskirts. There are some great parcels available in Apopka and the Clermont area.
But to really answer your question, please be a bit more specific as to the usage. For example, new construction, equestrian use, waterfront. etc. I would be happy to conduct a market analysis for you with a bit more info.
