Why wouldn't you sell or lease your Texas Commercial Property with a professional?

As a 40 year experienced commercial real estate broker / property manager in Texas - I just can not imagine why one would not make contact with one of the many outstanding commercial real estate agents in our great state to accomplish a sale or lease assignment.

I too am in the Commercial Real Estate business. We offer Tenant Representation. I get people all the time who think they can do this on thier own. They are under the impression that it costs more to use my services. In reality, the commissions are already allocated in the deal. So, in essense, the "do-it-yourselfer" is actually paying for me without using me. I mostly get this from small or start-up prospects. The "big boys" understand the value of what we do and have no problem hiring us.
I'm sure your experience may be similar.
