Ealtor, Zillow, Landwatch, LandsOfAmerica, though Realtor and Zillow are pretty tied to MLS and the otheres may have stale listings. Hardest thing for me was to be patient... took a year and many miles of driving to find something in your area (that we hope to close on 15ac next month).
Having lived in cities in all three states, before buying I looked hard at differences between AL, FL, GL... for our case
AL makes most sense, now that the guv is just an incompetent drunk, unlike those before her who were blatantly corrumpt
GA more expensive and unfortunately state level changes driven only by Atlanta needs, no consideration for anything else.
FL... part you're talking is beautuful but has all the problems of AL AND GA ('cept a govener hooked on drugs or just power, rather than booze)
Good Luck
