Why is residential real estate data available to almost everyone, while commercial real estate data remains locked behind expensive platforms?
In this episode, Aviva Sonenreich and Kayla Mahoney compare the vastly different worlds of residential and commercial real estate data. They discuss why Zillow has become the consumer-facing standard for residential real estate while CoStar dominates commercial real estate, and what those differences mean for brokers, investors, property owners, and buyers.
Together, they examine the economics behind real estate data platforms, the role of AI tools like ChatGPT in property analysis, and why commercial brokers continue to provide value through market knowledge, negotiation, and access to proprietary information. They also share how technology is changing the broker’s role—from finding properties to interpreting data, negotiating deals, and building systems that create better client outcomes.
