Need real estate agent for first commercial deal?

[Wesley Jensen]

I bought my first residential property (duplex) a few months ago and have come across what appears to be a good deal in a commercial property. So far I have a showing scheduled for tomorrow with the sellers realtor and the seller requested a pre qualification letter from my lender (which I have). Do I need my own realtor to represent me? I have never done a commercial deal, is it that different? Any advice or suggestions are greatly appreciated, thanks!
