What I have seen and you need to consider is that land you can make some decent income off of tends to be taxed accordingly. At least in my area. Ground that can be farmed or rented to a farmer will receive a higher assessment value by the local assessor's office. So, that being said - keep that in mind when you start looking. In my case the land was purchased with hunting as an after thought. As such of my 150 acres......I currently have about 100 tillable. I have implemented some CRP areas where it makes sense and I receive payments that will rival my rental rate I receive for the tillable land. Right now on my place I am getting roughly $200/acre in land rental for the tillable acres. The CRP acres are a nice way to build habitat while not giving up the $ to do it.....however it is limited in what you can enroll AND there are rules! There are some government programs as well (here they call it a classified forest program) where again the state government has rules and the like with what you can do to the area enrolled, but they also reduce your "habitat" ground to a tax rate of 1$ an acre. Also keep in mind that these programs stay with the land so it can reduce potential buyers if you are to ever try to sell AND getting out of those programs tends to carry heavy fines and the like as well. Many of these programs change from state to state so your area may be VERY different.
Trying to make money off a property to help put the property purchase in reach is great, but nothing is free and the government has figured out a way to tax everything and those that are not taxed are illegal! You want to make a few bucks then leasing it for someone to hunt a species you don't you could consider. Farming - grazing or row crops - takes valuable acres out of your control and may if your lucky cover your property taxes and then a bit more....maybe. Timbering is a 20 year event if you have something decent to start with and your not going to get rich cutting firewood or tapping maple trees for the most part. You want to get a property to pay for itself.....you better find oil, coal or gold or the like and then sell high and run like hell!
Good luck in your search, but many folks are out there looking for a way to turn a buck off of property.
