Just one botched sale can cost you much of the value of decades-old timber. No step in tree farming is more important than selling timber correctly. You cannot spend too much time studying how to do it and will be way ahead just by reviewing this guide.
An easy way for a do-it-yourselfer to quickly get into trouble is selling timber using "lump sum" value with only a handshake and without a tree inventory. Don't sell lump sum without a timber inventory, a contract and a payment check that won't bounce. Please find a professional partner!
Another way to get into big trouble is selling your timber on a "pay-as-cut" basis while letting the buyer both grade and measure logs without you or a representative inspecting his work. Pay as cut is where the buyer pays you by the log load as they are harvested. Don't sell by the log load unless you are willing to check each load and can verify the scaling rules. Again, get professional help!
