Which Broker to Use?

[Robert T.]

We have bought and sold many properties. Sometimes bought and sold without a broker. More often with a broker. We are about to list some commercial properties and while we have built good relationships with several brokers over the years, wish to seek BP property owner opinions of national chain brokers (e.g. Marcus Millichap or CBRE) versus a local sort of "mum & pop" commercial broker. Each have their strengths and weaknesses, but like to hear any stories or personal experiences.

"Sometimes bought and sold without a broker" if you have the experience, then why use a broker
