NJ Foreclosure Wholesaler/Flip ( how does this work)

[Chris Parr]

curious how wholesalers work with foreclosure properties.  Do they buy at auction and then look to sell to others in a quick cash transaction? Do they typically get involved before auctions and never take posession of a property? 

If anyone can share the process, I would like to learn more about what paperwork has to be filed, what costs they incur.  I am interested as a possible purchaser of a wholesale property so I would like to learn as much as possible about the steps involved.

Thanks
