Berkshire Hathaway’s HomeServices of America has announced a strategic partnership with Cotality, the real estate data and analytics company formerly known as CoreLogic, to launch BLX — a new listing data platform aimed at modernizing how real estate listings are entered, managed, and distributed across the industry.
The initiative seeks to solve a longstanding challenge in residential real estate: fragmented listing entry across multiple MLS systems. HomeServices currently works with more than 250 MLS relationships nationwide, where listing data is typically entered into local MLS platforms before being redistributed elsewhere. BLX is designed to streamline that process by creating a centralized, brokerage-level system for listing entry while continuing to support MLSs as a core part of the real estate ecosystem.
With BLX, agents and administrative teams will be able to enter property information once and distribute it across MLSs, consumer platforms, and other approved channels. The platform is expected to improve data consistency, reduce duplicate entry, and strengthen listing accuracy while remaining compliant with MLS standards and rules.
HomeServices CEO Chris Kelly said the platform reflects the growing importance of managing listing data more effectively. He emphasized that BLX is not intended to replace MLSs, but rather to improve how data flows through the system and enhance data integrity at its source.
The platform is also designed to integrate with existing agent workflows, minimizing disruption and reducing the need for additional training. Cotality, which rebranded from CoreLogic in 2025, brings extensive expertise in property data, analytics, and technology infrastructure to the partnership.
According to Cotality CEO Pat Dodd, the collaboration aims to simplify the listing process for agents while creating a more transparent and efficient experience for MLS partners, buyers, sellers, and brokerages alike.
Beyond operational improvements, BLX is expected to provide more real-time insights into pricing trends, market conditions, and listing performance, giving agents and clients stronger decision-making tools.
The initial rollout of BLX is expected within the next three to six months, with broader expansion planned alongside MLS partners across the country.
