check out east texas...pine tree farms are the thing out there.
20 acres aint much, but if ya plant it, or find one just started , in 20 years it will pay off pretty good, then ya buy 20 more acres next to it ya got 40...little at a time right?
i would just put 20k down on 100 acres and pay monthly for 20 years. after your tree's get big, ya get more money off 100 acres of tree's than ya do 20.
its cheaper than a lease for sure, and eventually you will own the land....but it aint 1200 acres like a lease is.
