Going at it alone?

[N/A N/A]

I have been searching for a duplex for around 6 months to do an owner-occupy to begin Real Estate Investing. I have just found one that I'm interested in. It is a FSBO. I currently have had a realtor who has showed me a few properties. The seller of this FSBO property has expressed that we could both save some money by not bringing in a Realtor. Do you think I need one? I've done quite a little bit of research, but am a little bit uneasy. His asking price is more than I had initially been planning on spending so I'm looking to cut corners where I can to make my offer the most attractive to him. The property has only been "on the market" for about one week.

Any fellow investors in the Lincoln, NE area?
