Introducing Smart Search

Smart Search moves beyond traditional filters and keywords to deliver more personalized, relevant results.

• Complex Queries: Search naturally, even with long, conversational phrases like, “ranch-style house with a pool in Austin.”
• Multi-Geo Searches: Explore multiple cities or neighborhoods at once, “2-bed condos in Arlington and Alexandria near metro stations.”
• Points of Interest: Find homes close to what matters most, “condos near CoStar’s Arlington and Richmond offices.”
• Speech-to-Text: Tap the mic and search how you speak, Smart Search does the rest.

Smart Search is built on cutting-edge natural language technology, so every search gets users closer to their dream home – turning their wish lists into results.

“Smart Search represents a new chapter in how people discover homes,” said Andy Florance, Founder and Chief Executive Officer of CoStar Group. “Too many users struggle with clunky filters and rigid forms that make finding the right home more difficult than it should be. We intentionally built Smart Search to remove those barriers - to allow people to simply ask for what they want, in their own words, and see accurate, personalized results instantly.”

Florance continued: “At CoStar Group, every innovation we create starts with our customers in mind. Smart Search is designed to save people time, reduce frustration, and make home discovery intuitive and even fun. Whether you’re a first-time buyer, a renter looking for your next neighborhood, or just exploring what’s out there, Smart Search delivers clarity where there used to be confusion. It’s the easiest way to find your home - and we’re just getting started.”

From first-time buyers to curious explorers, Smart Search makes finding the perfect home simpler for everyone and it’s available across every search type on Homes.com.
