Commercial real estate prospecting and deal origination remain among the most time intensive activities in the industry. According to CBRE’s 2025 Capital Markets Report, the average institutional acquisition team screens more than 200 properties for every transaction that closes, with ownership identification and contact verification consuming 30 to 40 percent of the sourcing cycle. JLL’s 2025 Brokerage Efficiency Study found that CRE professionals spend an average of 12 hours per week on property research and owner outreach, much of it manually cross referencing county records, corporate registrations, and fragmented databases. The National Association of Realtors reported that commercial transaction volume exceeded $800 billion in 2024, yet the tools available for identifying who actually owns a given property have historically lagged far behind the sophistication of the deals themselves. The gap between transaction velocity and data accessibility has created persistent demand for platforms that can aggregate property intelligence at scale.
Reonomy addresses this gap with an AI powered property intelligence platform that covers more than 54 million commercial properties and 68 million property transactions across the United States. The platform uses proprietary machine learning algorithms to aggregate, structure, and connect property data from thousands of sources, piercing LLC layers to identify true property owners and providing accurate contact information including phone numbers, email addresses, and mailing addresses. Originally founded as an independent proptech company, Reonomy was acquired by Altus Group in November 2021, adding the backing of a global commercial real estate software and data analytics firm. The platform is priced at approximately $400 per user per month with a seven day free trial, making it one of the more transparently priced enterprise CRE data platforms on the market.
Reonomy earns a 9AI Score of 78 out of 100, reflecting exceptional CRE relevance and data quality, strong pricing transparency, and a well established market position. The platform’s combination of machine learning powered ownership intelligence, comprehensive property coverage, and accessible pricing makes it a compelling tool for CRE prospecting, deal sourcing, and market analysis workflows.

What Reonomy Does and How It Works
Reonomy is a commercial real estate data platform that combines property records, ownership information, transaction history, mortgage data, and contact details into a unified intelligence layer. The platform ingests data from thousands of public and proprietary sources, including county assessor records, deed filings, corporate registrations, mortgage origination documents, and business databases. Reonomy’s proprietary machine learning algorithms process this raw data to create a structured, searchable database organized around what the company calls the Reonomy ID, a unique identifier that links disparate data points about each property into a single comprehensive profile.
One of the platform’s most distinctive capabilities is its ownership resolution engine. Commercial properties are frequently held through LLCs, trusts, and multi layered corporate structures that obscure the identity of the beneficial owner. Reonomy’s algorithms trace these ownership chains to identify the actual decision makers behind property holdings, then cross reference billions of contact records to provide verified phone numbers, email addresses, and mailing addresses. This capability transforms what was traditionally a manual, multi hour research process into an automated workflow that can deliver ownership intelligence in seconds.
The web application allows users to search for commercial properties by location, sale date, owner portfolio size, asset type, loan origination date, and mortgage amount. Users can build targeted prospect lists based on property characteristics, ownership patterns, and financial attributes. The platform also provides property level analytics including assessed value, tax history, building specifications, and comparable sales data. For enterprise clients, Reonomy offers API access and data licensing options that allow firms to integrate property intelligence into their own systems and workflows. The Altus Group acquisition in 2021 has expanded the platform’s data resources and positioned it within a broader ecosystem of commercial real estate analytics and valuation tools.
9AI Framework: Dimension by Dimension Analysis
CRE Relevance: 10/10
Reonomy is built exclusively for commercial real estate, with every feature and data source oriented toward CRE property intelligence, ownership identification, and deal sourcing. The platform covers 54 million commercial properties across all 50 states and all major asset types including office, industrial, retail, multifamily, hospitality, and special purpose properties. Every workflow in the platform, from property search to owner contact retrieval to portfolio analysis, addresses a recognized CRE operational need. The platform does not attempt to serve adjacent industries or repurpose generic data tools. This singular focus on commercial real estate makes Reonomy one of the most CRE relevant platforms in the entire AI tools landscape. In practice: Reonomy is a pure play CRE data platform where every feature, data source, and workflow directly serves commercial real estate professionals.
Data Quality and Sources: 9/10
Reonomy aggregates data from thousands of public and proprietary sources, creating a unified property intelligence layer that covers 54 million commercial properties and 68 million transactions. The platform’s machine learning algorithms are specifically designed to resolve ownership ambiguity by piercing LLC structures and matching beneficial owners to verified contact information. The Reonomy ID system creates a persistent, unique identifier for each property that connects disparate data points across sources, which reduces the reconciliation errors that plague manual research workflows. Data freshness varies by source, with some records updating in near real time and others reflecting periodic batch updates from county and state databases. The Altus Group acquisition has expanded access to additional data assets, particularly in the valuation and analytics space. In practice: Reonomy’s data quality is among the strongest in the CRE property intelligence category, with particular strength in ownership resolution and contact verification.
Ease of Adoption: 7/10
Reonomy offers a seven day free trial that allows prospective users to evaluate the platform’s capabilities before committing to a paid subscription. The web application interface is designed for business users and does not require technical expertise to navigate. Users can begin searching for properties, identifying owners, and building prospect lists within minutes of account creation. The search interface supports both basic filters (location, asset type, sale date) and more advanced queries (loan origination, portfolio size, corporate structure). The learning curve is manageable for CRE professionals who are familiar with property data concepts, though the full power of the platform’s advanced filtering and list building capabilities requires some exploration. Enterprise features including API access and data licensing have a higher adoption threshold that requires technical implementation. In practice: individual users can start extracting value from Reonomy quickly through the web application, while enterprise deployments require more structured onboarding.
Output Accuracy: 8/10
Reonomy’s output accuracy is strongest in its core competency of property data aggregation and ownership resolution. The platform’s machine learning algorithms are designed to handle the complexity of commercial property ownership structures, including multi layered LLCs, trusts, and corporate entities. Contact verification is powered by cross referencing billions of records, which produces accurate results for the majority of commercial property owners. Property data accuracy depends on the freshness and completeness of underlying source records, which can vary by county and state. Capterra and GetApp reviews indicate that users generally find the data reliable for prospecting and research, with occasional gaps in smaller or less active markets. Transaction and mortgage data accuracy is high for recent activity but may be less complete for historical records in some jurisdictions. In practice: Reonomy delivers reliable property and ownership intelligence for mainstream CRE markets, with users advised to verify critical data points through independent sources for high stakes transactions.
Integration and Workflow Fit: 6/10
Reonomy provides API access and data licensing for enterprise clients, which allows firms to integrate property intelligence into CRM systems, proprietary analytics platforms, and deal management workflows. The platform also supports data exports in standard formats for offline analysis. However, Reonomy does not offer native integrations with CRE property management systems such as Yardi or MRI, or with CRE deal management platforms like Dealpath. The platform operates primarily as a property data and prospecting layer rather than as an embedded component of end to end CRE workflows. The Altus Group ecosystem provides some integration opportunities with Altus’s other products, but the breadth of native CRE system connectors remains limited. In practice: Reonomy integrates well with custom data workflows through its API but lacks the native CRE system connectors that would make it a seamless part of an integrated property management or deal management tech stack.
Pricing Transparency: 8/10
Reonomy is one of the more transparently priced enterprise CRE data platforms. Standard pricing is approximately $4,800 per year per user (or $400 per month), with access to all geographies and property types across all 50 states included in the subscription. Discounts are available for annual prepayment, and the platform offers a seven day free trial that allows users to evaluate the full product before committing. This level of pricing visibility is uncommon among CRE data platforms, where custom pricing and mandatory sales conversations are the norm. The published pricing makes it straightforward for firms to budget and compare Reonomy against alternatives without engaging in extended procurement processes. In practice: Reonomy’s pricing transparency is a significant differentiator in the CRE data market, with published rates and a free trial that reduce procurement friction.
Support and Reliability: 7/10
Reonomy operates under the Altus Group umbrella, which provides institutional backing and enterprise grade infrastructure. The platform offers customer support through email and in app channels, with dedicated account management available for enterprise clients. The web application is cloud based and generally reliable, though some user reviews mention occasional performance issues during complex searches with multiple filters. The Altus Group acquisition has enhanced the platform’s operational stability and expanded the resources available for ongoing development and support. Documentation and help resources are available through the platform’s support center, and the company provides onboarding assistance for new users. In practice: support is solid and backed by an institutional parent company, with typical enterprise grade responsiveness for account inquiries and technical issues.
Innovation and Roadmap: 7/10
Reonomy’s core innovation is its machine learning powered ownership resolution engine, which represents genuine technical differentiation in the CRE data market. The Reonomy ID system, which creates a unique persistent identifier for each commercial property, is a foundational innovation that enables cross source data linking at a scale that manual processes cannot replicate. The Altus Group acquisition has positioned Reonomy within a broader innovation ecosystem that includes ARGUS valuation software and other CRE analytics tools, which creates opportunities for cross product integration and feature expansion. However, the pace of public feature releases has been moderate since the acquisition, and the platform’s core functionality has remained relatively stable. In practice: Reonomy’s foundational ML technology is genuinely innovative, and the Altus Group ecosystem creates a strong platform for continued development, though the cadence of visible innovation could be more aggressive.
Market Reputation: 8/10
Reonomy has established a strong reputation as one of the leading CRE property intelligence platforms in the United States. The 2021 acquisition by Altus Group validated the platform’s commercial viability and market position, integrating it into a global CRE software ecosystem. The platform is widely referenced in CRE industry publications and has been recognized as a top data source by CRE Daily, GetApp, and other review platforms. User reviews on Capterra and G2 are generally positive, with particular praise for the platform’s ownership data and prospecting capabilities. The combination of broad property coverage (54 million properties), transparent pricing, and Altus Group backing creates a credibility signal that resonates with institutional and mid market CRE firms. In practice: Reonomy is a well recognized and respected CRE data platform with institutional backing that reinforces its market credibility.
Who Should Use Reonomy
Reonomy is an essential tool for CRE investment sales brokers, acquisitions teams, and capital markets professionals who need to identify property owners and build targeted prospect lists at scale. The platform is particularly valuable for firms that source deals through direct outreach rather than relying exclusively on listed inventory. Lenders and loan originators benefit from the platform’s ability to identify borrowers and assess property collateral through transaction and mortgage data. Institutional investors and private equity firms can use Reonomy to screen markets, identify acquisition targets, and analyze ownership patterns across portfolios. The transparent pricing and seven day free trial make it accessible for individual practitioners and small teams that want to test the platform before committing.
Who Should Not Use Reonomy
Reonomy is less suitable for CRE professionals who focus primarily on property management, asset operations, or tenant facing workflows rather than deal sourcing and prospecting. The platform does not provide operational tools for managing leases, tracking maintenance, or processing rent payments. Firms that need deep integration with property management systems such as Yardi or MRI will find Reonomy operates as a separate data layer rather than an embedded module. International CRE firms will also find limited value, as the platform’s coverage is focused on the United States. Teams that already have comprehensive access to CoStar’s ownership data may find some functional overlap, though the platforms serve partially different use cases.
Pricing and ROI Analysis
Reonomy is priced at approximately $4,800 per year per user ($400 per month), with discounts available for annual prepayment. The subscription provides access to all geographies and property types across all 50 states. A seven day free trial allows users to evaluate the platform before committing. The ROI case for Reonomy centers on time savings in property research and owner identification. A broker or acquisitions professional who saves even five hours per week on prospecting research can justify the subscription cost through recovered productive time. For firms that close one additional deal per year as a result of better prospecting data, the annual subscription cost is negligible relative to transaction fees or investment returns. The published pricing eliminates procurement friction and allows teams to budget with confidence.
Integration and CRE Tech Stack Fit
Reonomy provides API access and data licensing for enterprise clients that need to integrate property intelligence into CRM systems, deal management platforms, or proprietary analytics tools. The platform supports standard data exports for offline analysis and prospect list building. Within the Altus Group ecosystem, there are natural integration opportunities with ARGUS and other Altus products, though native cross product connectors may still be developing. The platform does not offer out of the box integrations with Yardi, MRI, CoStar, or Salesforce CRM, which means firms must build custom integrations or manage data through manual workflows. For teams that use Reonomy primarily as a prospecting and research tool, the web application is self contained and does not require system integration to deliver value.
Competitive Landscape
Reonomy competes with CRE property data platforms including CoStar, which offers broader market analytics alongside property and ownership data, and PropertyShark, which provides detailed property reports for specific markets. CompStak competes in the lease comp and transaction data segment. Reonomy differentiates through its machine learning powered ownership resolution, which traces LLC structures to identify true beneficial owners, and its relatively transparent published pricing that contrasts with the custom pricing models of larger competitors. The Altus Group backing provides additional differentiation through access to ARGUS valuation data and a broader CRE analytics ecosystem. While CoStar’s total data coverage is more comprehensive, Reonomy’s focus on ownership intelligence and prospecting efficiency creates a distinct value proposition for deal sourcing teams.
The Bottom Line
Reonomy is a strong CRE property intelligence platform with exceptional relevance, deep data coverage across 54 million commercial properties, and a machine learning engine that excels at ownership resolution and contact verification. The transparent pricing at $400 per month per user and seven day free trial set it apart from competitors that require lengthy sales processes. The platform’s primary limitations are moderate integration depth with CRE systems and a U.S. only coverage footprint. For CRE professionals who need to identify property owners, build prospect lists, and source deals through direct outreach, Reonomy delivers measurable value with minimal procurement friction. The 9AI Score of 78 reflects a solid platform with particular strength in data quality, CRE relevance, and pricing accessibility.

Frequently Asked Questions
How does Reonomy identify the true owners behind LLCs and corporate entities?
Reonomy uses proprietary machine learning algorithms that trace ownership chains through multiple layers of corporate registrations, LLC filings, trust documents, and public records. The platform cross references billions of data points to connect properties held through opaque structures to the beneficial owners who control investment decisions. This process, sometimes called LLC piercing, automates what traditionally required hours of manual research through county records and secretary of state filings. The algorithms also match identified owners to verified contact information by scanning business directories, corporate filings, and professional databases. According to industry estimates, approximately 60 to 70 percent of commercial properties in major U.S. markets are held through LLC or trust structures, which makes this ownership resolution capability essential for effective prospecting and deal sourcing in commercial real estate.
What types of CRE professionals benefit most from Reonomy?
Investment sales brokers and acquisitions professionals benefit most from Reonomy because the platform directly addresses their core workflow of identifying property owners, building prospect lists, and initiating outreach for off market deals. Capital markets teams at brokerage firms use the platform to identify potential sellers and borrowers based on property characteristics, transaction history, and loan maturity schedules. Institutional investors and private equity firms leverage Reonomy for market screening and target identification across geographic areas and asset types. Commercial lenders use the ownership and mortgage data to identify refinancing opportunities and potential borrowers. According to CBRE’s 2025 analysis, firms that use AI powered prospecting tools report 25 to 35 percent higher deal flow compared with teams relying on traditional manual research methods.
How does Reonomy pricing compare to competitors like CoStar?
Reonomy’s published pricing of approximately $400 per month per user ($4,800 annually) is significantly more accessible than CoStar’s enterprise pricing, which typically starts at several thousand dollars per month per user depending on the market coverage and product modules selected. Reonomy also offers a seven day free trial, which CoStar does not provide for its core products. The tradeoff is that CoStar offers a broader data ecosystem that includes listings, market analytics, lease comps, and news alongside property and ownership data, while Reonomy focuses specifically on property intelligence and ownership resolution. For firms that primarily need prospecting and ownership data, Reonomy offers strong value at a lower price point. For firms that need comprehensive market analytics and listings data alongside ownership intelligence, CoStar’s broader platform may justify its higher cost.
What happened after Altus Group acquired Reonomy?
Altus Group, a global provider of commercial real estate software and data analytics, acquired Reonomy in November 2021 to expand its property data capabilities and strengthen its position in the CRE technology market. The acquisition integrated Reonomy’s property intelligence platform into the Altus Group ecosystem, which includes ARGUS (the industry standard for commercial real estate valuation and asset management) and other analytics products. Post acquisition, Reonomy has continued to operate as a distinct product while benefiting from Altus Group’s data resources, financial stability, and enterprise client relationships. The acquisition has positioned Reonomy within a broader institutional framework, which enhances its credibility for enterprise buyers and creates opportunities for cross product integration. The platform’s core functionality, pricing model, and user experience have remained largely consistent since the acquisition.
How comprehensive is Reonomy’s coverage across U.S. markets?
Reonomy covers more than 54 million commercial properties and 68 million property transactions across all 50 U.S. states. The platform provides access to all major asset types including office, industrial, retail, multifamily, hospitality, self storage, and special purpose properties. Coverage is strongest in major metropolitan markets where county records are digitized and regularly updated, with data depth including property characteristics, assessed values, tax history, transaction records, mortgage information, and ownership details. In smaller or rural markets, data completeness may vary depending on the digitization status of local county records and the availability of electronic filing systems. The subscription includes access to all geographies without additional per market charges, which means users can search nationally without worrying about incremental costs. For national brokerage firms and institutional investors that operate across multiple markets, this comprehensive coverage eliminates the need to subscribe to multiple regional data providers.
