Price per acre completely depends on area, size and demand, could be a low as $6 to $8 an acre or as high as $20 - $25 and up. It's best to reference lease prices in the area/county you are looking at.
I don't know per acre? My buddy let's me hunt behind his house and I set up all the front and rear ends on his projects lol. I love hunting, myd trucks and racecars. I win either way! But in Wilkinson County the lease I am in is roughly $14 an acre
12 to 15/acre is a fair rate to pay for most timber properties in Ga. We pay around 12 per for 609 acres in Troup county. Well worth it to me since it's right behind my house.........
