Please be aware that auctions are conducted on a cash-only basis ... you'll need to submit certified funds in order to be able to bid. If the sale exceeds the amount of your check, you'll have a short period (usually 30 days) to remit the balance. The homes are sold "as-is, where-is," with no opportunity to view or inspect the property until you own it. There's always the possibility that it will need considerable work ... foundation, under-slab plumbing, roof, etc. Your competition will be experienced investors, who know of the pitfalls and have the wherewithal to make the necessary repairs and improvements. You really need to ask yourself whether you have that kind of money and are willing to take the risk.
The figure quoted will likely be the opening bid ... expect the home to sell for considerably more. These "courthouse steps" auctions are obviously not for the faint of heart. Proceed with caution ... I wish you well.
