Found property and am comfortable negotiating- Still needRealtor?

[David M.]

We own a 4 unit building with limited parking and the Jiffy Lube next door is for sale. We are interested in buying it to have two properties and to be able to increase parking. (do you like this idea?) We have located the property ourselves and feel comfortable in a negotiating environment-- Do we still need a commercial realtor? Would we be doing a disservice to ourselves by using a real estate lawyer to review the documents and handle the rest by ourselves? What would a real estate realtor do for us that we couldn't do with the assistance of an attorney?
