Hypothetical Question re Foreclosure auctions

[Eric M.]

I asked this question of my attorney today and he wasn't sure. Said he had never heard of this happening. Wondered what any of you might think.
In my state, after you win a bid at Sheriff Sale, you wait a few weeks until a judge confirms the sale, then you wait 30 days to get possession of the property.
Often when I buy a property at Sheriff Sale it is actively on the MLS.

I wonder what would happen if the foreclosed owner accepted an offer between auction and confirmation.

If it happened between confirmation and possession, I would feel confident I would be considered the owner of the property. But not sure about before confirmation.

What do you think?
