There are pros and cons of selling your home by auction. We have used this technique to sell our listings in the past and overall, we felt the Cleveland area market is not ideal for it. The local agents don't understand it and buyers also seem a little fearful as well.
I am in no ways knocking the use of an auction to sell a home, but would caution you from jumping into it without learning more. In answer to your first question, I have a friend who is a licensed auctioneer here in town and would be happy to make an introduction so you can get information directly from him. You have nothing to lose by learning about your different options.
I hope this is helpful and best of luck to you.
