if you never done it, be careful.
every auction company or area is different, you need to read the auction term before you go.
1. SFH usually same day closing, you get a certificate then a sheriff deed will mail to you.
2. you need to know who is foreclosing what, junior lien can't wipe out senior liens.
3. before they register you, most time you require to bring a cashier's check plus cash, but some just let you show a bank certify letter for proof of funds available.
4. some auction require you pay on end of auction, can't even leave for a sec, some close at end of day, meaning you can go get a check and come back. higher price auction, sometimes let you close in 30 days.
