There are several companies that have auctions all over the country. I'm sure if you do a google search you will be able to find a few in the area you are looking to purchase.
I would not recommend an auction unless you are an investor and have tons of time. Remember, you are not the only person bidding on these homes, and you may find 4 or 5 you are interested in buying, only to walk out empty handed because someone else out bid you.
Also realize you have to do your inspections and be prepared to close quickly in most cases.
It may be more productive to hire a qualified Realtor to assist you in finding what is on the open market.
I wish you all the best.
