There is no question that you can make a lot of money and have a lot of fun in the commercial field. But it is not easy nor for the faint of heart. Listing to sale could take years. You need to be with a company known for doing commercial deals. Can you weather long periods between commission checks. Also, you need to look at the turnover rates of commercial properties in your market. Most houses will turnover, re-sale in twelve years. Big office buildings may only re-sale once in your life time. Give this a lot of thought.
