The best adive would be to hire a professional to help provide you with the best possible data if you are considering buying or leasing in the CBD. Square foot cost is only one way to look at a commercial property. There are so many other factors you should consider. ie intended use v. allowable use, renovation cost, expenses, etc., etc.
send me a message if I can help
