Enrolled in forestry program means the owner has signed an agreement with the state in which his land has a much reduced property tax rate in return for the land being open to the public for recreational purposes (access to fishing, hiking, hunting, etc). There are regulations for cutting timber. The same hunting rules that apply on state land apply to forest management land... no permanent nor "overnight" tree stands, no tree trimming / cutting shooting lanes, no camping, no fires, etc . No motorized vehicles (snowmobiles / ATVs) unless there is a marked trail for them. However, as it's your land, those rules do not apply to
you nor anyone you designate. But the public is free to hunt or hike on it, and you cannot keep them out. I'm not sure if you, as a new owner, must abide by the program, and whether or not you can un-enrole.
Wetland usually means you cannot build on it because it will not perk for septic, and you cannot fill in designated wetland.
There's usually a reason these properties are for sale.
Another option is to look at paper company land that is for sale. Wausau Papers has been selling off a lot of land in the area of Hwy 64, and northward.
And there's always tax delinquent properties that have been seized by county governments for tax foreclosures. For them, go to each individual county website and search for their land department. This type of land sale is always in the legal notices of local papers and on county websites. I'm watching one near me in Vilas that is currently being sold by the county. I've hunted on it since they took it 2 years ago, it's less than a mile from my house. It's 50 acres of swamp, but full of deer. Opening minimum bid was way too high, I'm waiting for it to drop.
prebans is the real estate guy here, he'll know the correct answers. I had a real estate license 30 years ago when my mom was a C-21 broker, and I remember some stuff, but that was mostly urban and in another state (s.w. burbs of Chicago).
