Featured Testimonials

  • “Starting out in commercial real estate, information is the difference. CoStar is really my platform to build a business. It makes great careers possible.”

  • “Thanks to CoStar, we can see what’s available in a specific area; whether the kitchens and baths are updated; and other key information. We’re able to create a game plan to determine what properties would get a strong premium after a renovation; how the market is performing before we begin construction in certain neighborhoods; whether we’ll need to offer concessions to be competitive; or whether the market is healthy enough that we can grow rents without having to give anything away for free.”

  • “Having CoStar is like having a personal assistant, It saves me from hiring additional staff and the associated costs, which at a minimum would be $50,000 each year. CoStar is really my assistant, researcher and analyst, all in one.”
