CoStar: A broader CRE data platform covering lease comparables and market analytics rather than primarily ownership and contact data
Reonomy
Commercial property ownership and contact data platform, acquired by Altus Group for roughly $202 million and now sold on unpublished, increasingly enterprise-focused pricing
As of 1 September 2026, Reonomy's pricing is not published; the vendor quotes on request. A CRE data product covering ownership, contact and transaction data used mainly for off-market deal sourcing and outreach, distinct from valuation modelling. Softwr lists it under Real Estate. Reonomy is made by Altus Group, available on Web.
Overview
What Reonomy does
Reonomy provides commercial property ownership records, owner contact information, transaction history and portfolio data, aimed primarily at brokers, lenders and investors trying to identify and reach out to property owners for off-market deal sourcing, rather than at valuation modelling, which is the ARGUS side of the same parent company business. The ownership fact worth flagging is that Reonomy was acquired by Altus Group in November 2021 for approximately $201.5 million ($198.5 million cash plus $3 million in shares), placing it in the same corporate family as ARGUS Enterprise. Since then, sources describe Reonomy pricing and packaging evolving toward a more enterprise-focused sales process than in its earlier, more self-service years, which is consistent with what typically happens to a data product after acquisition by a larger platform company. Buyers are commercial brokers, lenders and investors doing off-market outreach and portfolio research, distinct from CoStar main buyer base of brokers and analysts wanting comparables and market analytics. Reonomy offers monthly and annual subscriptions, with annual saving roughly 30% over monthly, but exact rates are not published and the sales process now skews toward larger accounts.
What people use it for
- A broker sourcing off-market deals by identifying and directly contacting property owners matching acquisition criteria
- A lender researching an owner portfolio and financing history before extending credit
- An investor doing outbound outreach to owners of a specific property type or size in a target market
- A firm already using ARGUS Enterprise considering Reonomy for data given the shared Altus Group ownership

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Reonomy.
- Pricing is not published, and the sales process has become more enterprise-focused since the Altus Group acquisition, which reportedly makes it less accessible for smaller, self-service buyers than it once was.
- It is a data and contact-sourcing tool, not a valuation platform, so firms needing DCF modelling still need ARGUS Enterprise or an equivalent separately, even though both are Altus Group products.
- Coverage and data freshness for ownership and contact information vary by market, and off-market sourcing quality depends on how current that contact data actually is.
- Shared ownership with ARGUS under Altus Group means a firm concentrating spend with both products has less independent competitive leverage across its CRE software and data budget.
- As with any owner-contact database, deliverability and accuracy of contact information degrade over time, and there is no independent public benchmark of Reonomy data accuracy to check ahead of purchase.
