Apartments.com is one of the largest online rental marketplaces in the United States, helping millions of renters find apartments, condos, townhomes, and houses for rent. The platform serves as a comprehensive resource for apartment hunters, offering detailed listings with photos, floor plans, pricing information, and amenity details. As a subsidiary of CoStar Group (acquired in 2014), Apartments.com operates as a key component of CoStar's residential real estate portfolio alongside ApartmentFinder.com and other rental platforms.

Apartments.com provides property managers with tools to market their available units, manage leads, and connect with prospective tenants. The site attracts significant traffic through both organic search and paid advertising, making it a critical marketing channel for the multifamily housing industry. Within the AdTech ecosystem, Apartments.com operates as a vertical-specific marketplace that monetizes through advertising placements and premium listing products. Property owners can purchase enhanced visibility through featured listings, premium placements, and targeted advertising to reach renters searching in specific markets.
