Buying at a County Public Auction - Questions

[Steve Preston]

Ok. This is my first ever post after the initial Hello, so please bear with me :)

1) Is there ever likely to be a case where a house is purchased through the Public County Auction system where people - the original owners or renters, maybe even squatters - are still inhabiting the property and have to be evicted by the new property owners?

2) Will a Title search show all Liens and Encumbrances on the property if completed prior to the sale?

3) How would an easement affect the purchase and where would information on easements be found?

Thanks in advance.
