Having purchased land, built a nice camp then purchased more land with cabins that were rented (tenants) out all with partners I can say your very wise if you can float the costs on your own as you save yourself "a LOT" of headaches with no partners involved. I can not stress this point enough, avoid partners if you can possibly afford to do this on your own. The big benefit is "freedom of decision", the down side is get to pay all the bills. The freedom is worth the cost.
Knowing what specifically you want to hunt and how far your willing to travel from home are some basic decisions. Also do you wish vacant land or land with an existing camp/cabin, or you your flexible on that point. Building a cabin from scratch can be a real chore while your tenting to do it. Do you want to hunt alone or with friends, if so how many, this dictates size. The farther north you go and away from major centres the more reasonable land costs are, and of course if you want water front no matter where it is it will cost you considerably more.
There are several real estate agents that specialize in camp and wilderness properties the names of which I can not recall. Google will be your friend once again. Anglers and Hunters mag very often has camp properties listed for sale. Agents in your areas of interest are also good contacts as that's how we found our property years ago.
This buying land and building a camp is one area where I have experience coming out my ying yang. Been there, done that, and have all the possible T shirts. It can be the most rewarding thing and at the same time the most frustrating venture you have ever done. Think it through thoroughly, take your time, avoid partners if at all possible, and follow your gut feelings.
