YYYAAAHHHOOOO update on deal #2

So I bought this foreclosure at an on line auction site for $2200 in Detroit. This happened this past Tuesday while in the 2nd day of class with the mentors. Called a real estate agent that night to take a look see and peak in the windows. He called me today and offered me 6k. I said the deed will not even be ready for a a few weeks, Let me think about it.
Now I have to ask myself why was he so hot to buy? Think I'll just drive up there and see for myself. He told me it was unusual in that area for a foreclosed property to look so good and still have appliances in the kitchen. Sounds like a rental to me, or certainly more than 6k, when comps show surrounding props selling from 18-40k
