What It Is

Broker Union is a real estate infrastructure platform operated by Listing Data LLC, serving brokerages, MLSs, portals, and data brokers. It is not a real estate brokerage, lender, or title service provider. Instead, it offers a federated software network for listing, transaction, and analytics data, with a focus on multi-party data publishing, data consumption, permission boundaries, and API standardization.

Core Capabilities

On the brokerage side, it supports multi-office operations, including per-office walls, shared inventory, centralized compliance, and reporting, making it suitable for franchises or cross-regional brokerage groups. On the MLS side, it emphasizes a modern MLS model based on hosting rather than seats, with RESO Web API v3 compatibility and member workflows. On the data side, it uses a unified canonical schema to bring active listings published by portals and closed transaction data published by brokerages into the same API. Consumers can pull comps, leads, valuations, AVM data, and market analytics. For AI, the platform does not include its own proprietary model; instead, it allows integrations with Anthropic, OpenAI, local models, and others, while the network provides permissions, citations, and tenant boundaries.

Pricing and Trial

The official website clearly uses enterprise/negotiated pricing and emphasizes that bills do not increase simply because more agents are added. MLS pricing is based on hosting rather than seats. Final costs depend on the tenant subscription or API consumption agreement; where no agreement exists, the rates in the admin console apply. Sandbox/evaluation access is free but rate-limited and does not include contract-restricted fields.

Pros and Cons

Its strengths are a clear positioning and a strong focus on the real estate data ecosystem, offering unified APIs, provenance fields, and tenant isolation, which may help reduce reliance on aggregator middle layers. Infrastructure-based pricing may also be more favorable for larger teams. The drawbacks are that public information is limited: it does not disclose specific pricing, SLA details, customer case studies, SOC 2/ISO security certifications, and there is little information on the product interface or implementation timeline.

Best Fit and Access from China

It is best suited to brokerage groups, MLSs, portals, and data product companies within the U.S. real estate ecosystem, rather than as a general-purpose CRM/SaaS product. Access from China is unknown, and payment methods are not disclosed. If serving Chinese real estate companies, key points to verify include network connectivity, contract payment arrangements, data compliance, and compatibility with local MLS/listing standards. Alternatives to consider include Propertybase, kvCORE, MoxiWorks, and Buildout; for domestic real estate digitalization in China, Ming Yuan Cloud and similar providers may be worth watching.
