ALE, we just finished one, but it was big and a really nice one. Comps were between 3-9 million. Let me know if these would help. But if you have a Mom & Pop type place, I don't think these would help ya'.
Last time I appraised one, I found quite a few comps from Costar.com. It was over five years ago, but some of the larger chain facilities change hands quite frequently.
