My advice, especially since your intention is permaculture homesteading, is to prioritize the growing season. In the long term, this can equate to financial success and sustainability. Among the states you listed, Georgia has the longest growing season. There are many factors not mentioned in your post that you may already be aware of, but for the sake of discussion, let’s delve into more details.
I have built two permaculture homesteads by myself and sold them for a considerable profit—one in Northwest Montana and the other on the Big Island. However, I found that a single individual can easily face burnout and may neglect important duties. As a result, I ended up living in a city until I could find like-minded individuals to partner with on a venture. My research into the real estate market, both domestically and internationally, has taught me a lot.
My top choice for investment is Nicaragua, as it is very friendly to permaculture practices, and many expatriates are recognizing its potential. The market is still quite affordable, providing a lot of value. Being aware of the challenges ahead can make a significant difference between success and failure.
I also have an interest in Belize since I do not speak Spanish and the economy is tied to the U.S. dollar. Additionally, its proximity to Mexico makes it easier to acquire supplies, and air travel to the U.S. is reasonably accessible. I also am elibable for the QRP (qualified retirement program) with an income of $2000 or more per month which enables me to have premanant residency unlike Nica. which most expats have to renew their visitors visa every 90, but still doable.
At any rate, good luck to you. Do you have your PDC yet?
