I wouldn't bet on a comeback in timber prices. Paperless offices arrived a few years ago and construction of new stick homes would have to skyrocket to make up for that market.
This would be a good time to use a land brokerage to unload the acreage on a timber company or outdoors enthusiast.
In my southern state, far-rural hilly wood land goes for $1500/acre. Near a town or level land might be $2500 and near a decent sized city might be $10k. In any case, this is a retirement opportunity so be careful who you hire to sell it for you.
