how to buy property before it goes to auction

[Suzanne HAINER]

I live in NC and have been to a couple of tax foreclosure auctions.  I would like to explore buying a tax foreclosure property directly from the owner before it goes to auction.  I am new at this so any advice would be greatly appreciated.  Would it be best to find a real estate agent experienced in foreclosures to work with?  Also, what exactly would my due diligence be before I approach the owner.  My thought is to buy the property then sell it for profit to another investor or flipper.  Can you wholesale these types of properties or is it best to sell conventionally after I take possession?  As you can see...so many questions!  Thank you for any response in advance!
