Unlike residential real estate, commercial real estate uses many different listing services. We use up to about 14 different listing services. The company pays about, nearly $100,000 a year. The two primary services that we use are CoStar and LoopNet. We also use Catalyst property search and a host of others. This is to maximize the exposure your properties will receive on the internet, and also help us to do research to understand the best place to market your property.
