Hi Leah, welcome to Permies.
My wife and I currently do a sort of suburban homesteading in Tennessee, we're about 30 miles outside of Nashville, and are moving to a more rural location in TN this year to pursue more homesteading stuff on a larger parcel of
land, far away from Nashville. I can speak on what I'm familiar with and that's Tennessee as I've lived here my entire life. There's lots of rural properties for sale of a wide variety (woods, woods/pasture mix, no dwelling, with dwelling, etc.) of all sorts of sizes. There's 7, almost 8 frost free months in a year for
gardening and crops. A lot of just about everything (with some exceptions such as tropicals like citrus) will grow here. We get plenty of rain in a year, with the dry season being the fall. If you need a job or have a career, Nashville is booming with jobs-a-plenty, if you're willing to commute from rural homestead to the
city. TN has no income tax though we do have a 9.25% sales tax on everything. Weather patterns are changing and shifting a little, so we get our share of tornadoes in TN and mighty thunderstorms with large hail that just tears everything up. There's really no fracking going on in TN so ground
water supplies tend to be good. There's not nearly the scale of industrial agriculture as compared to Kentucky or corn belt states, so there's less chemical drift here, but there are still pockets of GMO corn and soybean going on in the state, just no sprawling mega-farms.
My wife and I looked at land for sale in KY, NC, VA, WV, and northern GA. I learned there's a ton of fracking going on in WV, unfortunately, it's a beautiful state. There were some nice looking places in KY, which has no sales tax, but also has big-ag firmly footed there with plenty of poisons being used annually. NC could have worked for us, but we were finding more plots of land suited for our needs and budget in TN. Interestingly, north GA was expensive compared to TN. We didn't want to go too far south as there starts to be no winter, and we like having some sort of four seasons, which meant FL was out for us. I think there's going to be pro's and con's to every state, and I believe knowing your needs and goals will help you choose the right one.
The more we looked, the more we came back to the state we live in. It really suits us for our lifestyle and our desires to have livestock and grow more food than we can currently do in our present location. If you have any questions about Tennessee I'll do my best to
answer them! Good luck in your search!
