CoStarGo enables users to take the entire CoStar property database into the field where much of their business is conducted.  Now brokers, as well as property owners, investors, lenders and appraisers, can save time and be more productive by having the information they need while on the go.  Commercial real estate professionals can instantly view properties around their current location, search availabilities, view current tenants, sale history, leasing and owner contacts in one easy to use interface. They can access the most extensive library of commercial property images in the industry right from the iPad, and email or video conference with clients seamlessly from their iPad.
