Teams replacing Reonomy should compare CoStar, CREXi Intelligence, CompStak, PropertyShark, and CommercialEdge first. These five platforms cover the main jobs Reonomy users cared about: property research, owner discovery, sales comps, tenant signals, and investment screening. Reonomy’s parent company, Altus Group, acquired the platform in 2021, which pushed many users to reassess data access, pricing, and workflow fit [source: Altus Group].

TLDR: A brokerage team that needs 200 owner records, 50 recent sales comps, and 25 likely sellers in one week may find that no single Reonomy alternative does everything perfectly. CoStar is strong for market research, CompStak is useful for lease and sales comps, and PropertyShark can work well for ownership checks in major metros. For example, an investor screening 100 small industrial assets might use CommercialEdge to spot tenant and loan signals, then use PropertyShark to verify LLC ownership details.

1. CoStar: Best for deep commercial property research

CoStar is one of the most common Reonomy alternatives for serious commercial real estate research. It tracks properties, tenants, asking rents, sales, availability, and market trends across many asset types.

It fits brokerages, lenders, appraisers, and institutional investors that need broad coverage. Its research depth is the main draw. The platform can help teams compare office towers, industrial parks, retail centers, and multifamily assets in one place.

Best for: market reports, property details, tenant research, sales history, and competitive analysis.

The annoyance: CoStar can feel heavy for smaller teams. Pricing is often a sticking point, and users may need training before they feel quick inside the system.

2. CREXi Intelligence: Best for deal flow and active listings

CREXi Intelligence works well for teams that want property data tied closely to active listings and investment opportunities. It gives users access to sales comps, owner data, debt data, asset details, and market insights.

CREXi is also known for its marketplace. That makes it useful for investors who want to research a property and then compare it with live opportunities. It can be especially helpful for smaller investment groups that care about speed more than dense research screens.

• Useful for: sourcing deals and tracking comparable assets.
• Strong fit: brokers, buyers, and sellers working on active acquisitions.
• Weak spot: data depth can vary by market and property type.

Honestly, it feels like users sometimes spend extra clicks checking whether a record is complete. That is not rare in CRE data, but it still slows the work.

3. CompStak: Best for lease comps and sales comps

CompStak is different from many owner-data tools. Its main value is verified commercial lease and sales comp data. For underwriting, that matters. Rent assumptions can make or break a deal.

CompStak collects data through a professional exchange model. Brokers, appraisers, and researchers contribute deal information, then use the platform to access verified comps. This can help reduce bad assumptions in pro formas.

Best for: office, industrial, retail, and multifamily comp analysis.

It is not the best choice if a team only wants to find hidden owners behind LLCs. It is better when the question is, “What are tenants really paying nearby?” or “Does this sale price make sense?”

4. PropertyShark: Best for ownership and parcel research

PropertyShark is a practical option for ownership research, property records, maps, liens, permits, zoning, tax data, and building details. It is especially useful in dense urban markets such as New York City.

Teams that relied on Reonomy for owner lookup may like PropertyShark’s direct style. A user can search by address, owner, parcel, or building. Records often include corporate owners, mailing addresses, debt history, and property tax clues.

Best for: title research, prospecting, ownership checks, and local property reports.

The catch is that its value depends heavily on the target market. In some areas, it feels rich and useful. In others, it may feel thinner than expected.

5. CommercialEdge: Best for investment screening and asset intelligence

CommercialEdge, from Yardi, focuses on commercial asset data, ownership, tenants, transactions, loans, and market analytics. It is often used by brokers, lenders, owners, and investors who want a clean view of buildings and portfolios.

Its strength is connecting property details with business signals. A team can review owners, financing events, tenants, square footage, and sale history. That helps with prospecting and investment review.

Best for: owner prospecting, portfolio research, loan maturity tracking, and investment screening.

For a capital markets team, loan and maturity data can be useful. A loan coming due within 12 months can signal a refinance need, a possible sale, or a fresh advisory opportunity.

How to choose the right Reonomy alternative

The right choice depends on the job. No platform wins every category. A small acquisitions team may care most about owner names and debt hints. A national brokerage may need tenant records, sales comps, and market reports across dozens of metros.

• Choose CoStar for broad research and institutional market data.
• Choose CREXi Intelligence for deal sourcing and listing-connected insights.
• Choose CompStak for verified lease and sales comps.
• Choose PropertyShark for ownership, parcels, and public record checks.
• Choose CommercialEdge for owner, tenant, loan, and portfolio intelligence.

Many firms use two tools instead of one. That may sound annoying, but it is often more accurate. One system finds the owner. Another checks the rent assumptions. A third confirms the sale comp. Bad data costs more than another login.
