Any foreclosure auction is going to work in a similar way. You won't be able to tour the property (although you can obviously do drive-bys). Assume that there is going to be damage and or repairs needed. Research the history of the property at the county registry of deeds - find out what was owed on the property, as well as any additional liens or levys. Due Diligence is key in these processes.
If you decide to go forward, and want to bid, make sure that you have your funding in place beforehand. This, for most people, will mean that you'll need a HML relationship beforehand, and will want to give them a heads up on what you're doing. You'll have a very short window (around 30 days usually) to close if you were to win the deal.
Day of, you'll need to bring a check (cashier's normally), and usually be pre-registered for the auction. Its pretty common to have to put 10% down (although I've seen this be has high as 20%).
Things to watch out for:
- Don't get caught up in a bidding war. This can feel exciting, but you need to have your numbers firmly in place before you ever place a bid, and know when to fold your hand.
- Be able to confidently walk away. I was in an auction around a year ago, where I am still 99% sure I could have won with my next bid. I walked away because I hit my threshold. Even another 5k would have skewed my model, and there's always another property.
- Have an exit plan - If you win, what are you going to do with the property. The clock starts ticking, and you are running in a negative situation until the property is sold or rented. Make sure that you have those carrying costs available, and budgeted for.
