Lien Issues on Foreclosure

[Robert Shoffner]

If a first mortgage forecloses on a house and it is bought at auction, it wipes out all the liens behind it (unless the auction price is high and then they would get paid in full or partially).

Property taxes and HOA liens would still be in front of the foreclosed mortgage, and so would still be attached to the property.

Aside from these, what liens would an investor need to be concerned about  (IRS liens, personal judgments, other types of liens) when bidding on foreclosures?

Conventional wisdom is to do a title search before bidding.
