Yours is a great question, and the answers below address all the issues in the Batle Creek Market. Although the supply has come down, there are still too many houses on the market, which means not only does your home have to be appropriately priced, it needs to be in great shape. It has been extremely difficult to get some clients to pay attention to market analysis. I personally don't accept listings that aren't appropriately priced. I would suggest you review the feedback from the buyers who looked at the home and make the adjustments necessary. It would also be a good idea to contact other Realtors from the area to get their opinions about price and condition of the home.
As for the auction idea, my previous broker tried it and it wasn't successful. You will still have all the standard inspection deadlines and other delays that a normal sale has, and it's just as likely that you won't have any more interested buyers than you did before. Plus the extra advertising costs (which are quite significant) are usually passed on to the seller. While it is another marketing avenue, the results are really not worth the effort for anyone involved.
