What should I know about using Hard Money for Auctions purchases?

[Marcus G.]

Hello, I'd like to know if anyone has experience in using hard money to purchase from an auction or auction sites like auction.com, hubzu, or Williams & Williams.  

My understanding is that most auction sites do not allow the buyer to use traditional financing. Can I use hard money to purchase a foreclosure from auction and then immediately refinance with a traditional bank? Please note I plan to live in this home as my primary residence.

I'm new to auctions and would love to hear from experienced professionals regarding this matter. Thanks
