What do I do once I find an off-market deal?

[Tyler Whatcott]

I'm getting ready to start looking for off-market deals through driving for dollars and direct mail. My question is, what do I do once I find a deal? I'm very new at this and want to know what I should expect before getting started. Do I need a realtor to do the deal once I find one? What's a good book, or guide for the whole process of closing a deal once found?
