@Moldova - I agree I think that commercial property marketing would be easier if the rest of the neighborhood is zoned for commercial use. I know that renting commercial property is more lucrative because usually when you rent out commercial properties the lease could be anywhere from one to five years.
In fact, my father in law owns a warehouse that he offers leases for ten years at a time. There is usually less hassle when dealing with businesses and you almost never have problems with a business defaulting on their lease payments.
He loves renting out his commercial property. He said that it was one of the best business decisions he ever made.
