I disagree on the lump sum method, timber people have lost their butts on lump sum sales so much they are very conservative on their cruises, lot of factors go into the final price. One thing, most companies don't have $150,000 or so they can write a check for on a sale. They have to borrow the money and the interest comes off of the sale price. With a well structured contract on a per ton price, using a honest buyer/logger is better. The contract should have had any concerns written into it. Visit the sale area as often as possible, have a neighbor or friend stop by. If you put a camera on the road make the time between pictures just a few seconds or you might miss two trucks going out together.
