Apers vs. Reonomy

Overview

Reonomy is a property intelligence platform that helps CRE professionals find and research properties. It aggregates ownership data, transaction history, building characteristics, and tenant information into searchable profiles. If you're prospecting for off-market deals, researching ownership structures, or building a target acquisition list, Reonomy is a data sourcing tool.

Apers is a deal underwriting and modeling system. Once you've found a property — whether through Reonomy, a broker, or your own network — Apers takes the deal documents and builds a financial model.

Reonomy helps you find deals. Apers helps you underwrite them. They're sequential steps in the same workflow. For a broader view, see our full comparison overview.

The Deal Lifecycle Pipeline

Every institutional acquisition moves through a predictable pipeline. Understanding where each tool sits in that pipeline is the key to using both effectively — and to not buying the wrong tool for the wrong job.

The typical deal lifecycle looks like this:

1. Sourcing. Identify target properties, research ownership, build prospect lists. This is Reonomy's domain — property intelligence, owner identification, and market screening.
2. Outreach. Contact owners or brokers. Request offering materials. This step is usually manual or handled by CRM tools.
3. Underwriting. Receive the OM, rent roll, and T-12. Extract data. Build a financial model. Size debt. Model the waterfall. Run sensitivities. This is where Apers takes over.
4. IC preparation. Package the model, assumptions, and sensitivity analysis into a recommendation. Apers generates IC-ready Excel workbooks with auditable formulas.
5. Close. Legal, due diligence, and closing. Neither Reonomy nor Apers participates directly here.

Reonomy owns steps 1-2. Apers owns steps 3-4. There is no overlap, no redundancy, and no substitution. A firm that sources 200 properties to underwrite 20 to close 2 needs both capabilities — but from different tools optimized for different problems.

When Reonomy Wins

• Off-market deal sourcing. Finding properties, identifying owners, and building target lists for direct outreach. This is Reonomy's core use case.
• Property research. Building characteristics, transaction history, mortgage data, and tenant information for a specific property or portfolio.
• Market screening. Filtering properties by type, size, location, ownership, and transaction history to identify acquisition targets.

When Apers Wins

• Everything after sourcing. Once you have the deal — whether from Reonomy or elsewhere — Apers handles the analytical workflow: document extraction via the knowledge engine, financial modeling, sensitivity analysis, IC preparation.
• Complex underwriting. LIHTC, waterfall distributions, development pro formas, multi-tranche debt. Reonomy provides property-level data; Apers builds the investment model. See how deal screening works in practice.

Using Both

The workflow is straightforward:

1. Reonomy: Identify target properties. Research ownership. Build prospect list.
2. Outreach: Contact owners or brokers. Receive offering materials.
3. Apers: Upload the OM and supporting documents. Generate the financial model. Run sensitivity analysis. Prepare IC materials.

Reonomy and Apers don't compete — they're different steps in the deal lifecycle. One finds opportunities, the other evaluates them.

What Teams Get Wrong

The most common mistake we see is teams trying to use one tool for the entire pipeline. This usually goes in one of two directions — and both are wrong.

Buying Reonomy for underwriting. Reonomy provides property-level data: building characteristics, ownership, transaction history, basic financials. That's useful context, but it's not a financial model. You can't size debt in Reonomy. You can't model a waterfall distribution. You can't run a sensitivity analysis on exit cap rates. Teams that try to stretch Reonomy into the underwriting stage end up manually building the same Excel models they were trying to avoid.

Buying Apers for sourcing. Apers doesn't have a property database. It doesn't know who owns the 150-unit multifamily building on Elm Street, what it last traded for, or whether the owner might be interested in selling. Apers starts when the deal documents arrive — not before. Using Apers to find deals is like using Excel to find deals. It's the wrong tool for the wrong job.

The correct framing: Reonomy is upstream, Apers is downstream. Reonomy narrows the universe of properties to a target list. Apers turns that target list (once offering materials are in hand) into investment decisions. Each tool is excellent at its job and poorly suited for the other's.

Teams that understand this distinction spend less money, move faster, and don't fight their tools. Teams that don't spend months trying to make a property database do financial modeling — or a modeling engine do property research.
