I would say one of the biggest influence on price besides size would be proximity to larger cities. The closer to Edmonton, Calgary or Grande Prairie, the more you will pay.
My line is just over 3 townships. At 10K per township plus 20K for the cabin that would be pretty close to what I paid. But I have been offered more for it since I bought it 4 years ago, and if one day I get offered what I want I'll be looking for another one
