Foreclosure details, sale date, and right of redemption

[David S.]

Just got a call from a motivated seller. Seems like a good deal, but one thing is making me wary. Both Zillow and the county website show the house as being sold at foreclosure 3 weeks ago. 

So where can I find out more information about this foreclosure? Would calling the county be worth anything? The records available on their website are minimal, so guessing they'd tell me I could only pull records in person. Could I get any information from the law firm listed in the foreclosure?  

Also, I'm in Minnesota which has a 6 month right of redemption. Since it's still within that period, is there anything else I would need to do, other than paying off the loan amount(plus penalties?).

Thanks.
