the state with the best deer hunting and lowest property taxes most states in the south east qualify... check non resident license fees as well if you are not going to live there, land in TN is cheap but non res license is almost $300.. I have owned land in TN,AL and GA, looking to buy some now in KY and it is fairly reasonable as is MO...
Once you get into the midwest IL,IW,KS etc land gets a little more pricey and property taxes go up as well..Extreme west TX land is cheap if you buy enough of it..
I used to sell hunting land all over the place east of the Mississippi..
They're not making any more land buy it now if you can.. It one of the best investments you can own.. I have very little money in the stock market it's all in paid for real estate..
