Due diligence before foreclosure auction bidding (other than property condition)

[Josh Corriveau]

What due diligence do you do on properties before bidding at a foreclosure auction? I'd imagine ordering a title search, but what else do you check on? The properties I'm considering are primarily going to auction for the 1st lien, but I'm curious what else may need to be considered for other liens that could be on the property/anything else messy that would be important to know, other than the condition of the property, which is usually only available for an exterior look when driving by?

Thank you!
