I've found that "craft" lumber, wide boards from cherry/walnut/hickory, sell very well. People like to make their own coffee tables, and simple furniture. It's difficult to make cash with framing lumber. If you have to pay for the log,,, milling costs,,, the big box store is hard to beat. I use framing lumber for myself, building everything with green wood. It shrinks, dries hard, and grips the nails very well.
I'm building a wood working shop now for myself. It will take me a year to complete, but it will be worth it. Once finished, then I'll try and build rustic furniture and other junk to sell to the tourists of Fredericksburg! You can turn nice lumber into furniture, and turn a good profit doing so.
