I'm interested in buying pasture land in Oklahoma this summer. The trick is that I won't be able to personally move there until 2011 or so. I've heard that unused land can decline in value since it will eventually forest. So I'm thinking of renting the land out, but am curious about the rates one gets in return. I understand people usually rent for grazing, or hay. Anyone know the common rental rates? Can anyone shed light on possible problems?
