CRE Deal Sourcing

The best deal sourcing platforms for commercial real estate.

Sourcing tools fill your funnel with listings, owners, and comps. The bottleneck is qualifying and underwriting what comes in. AcquiOS is the intake layer that sits on top of your sources: it captures every broker OM from email, scores each deal against your buy box, and underwrites in minutes, so the right opportunities rise to the top.

The short answer

CRE deal sourcing has two layers. Origination and data platforms - CoStar, Crexi, Reonomy, Archer - surface properties and owners to fill your funnel. AcquiOS is the intake and qualification layer: it captures broker OMs from email, scores every deal against your buy box with AcquiScore, and underwrites in minutes. The best-run teams pair an origination tool with AcquiOS so analysts only spend time on deals worth pursuing.

The Problem

Sourcing fills the funnel. Qualifying and underwriting what comes in is the real bottleneck.

Sourcing alone Origination tools without an intake layer

✕Data platforms surface listings and owners, but broker OMs still land in individual inboxes with no shared intake

✕Every sourced deal has to be manually reviewed to know whether it even fits the buy box

✕Analysts rebuild an Excel model from scratch for each opportunity worth a closer look

✕No searchable registry: the same deal gets screened twice, or two analysts call the same broker

✕Deal history and pass rationale live in inboxes and analysts' heads, not the system

✕By the time a deal is underwritten by hand, faster teams have already made their offer

✓AcquiScore rates every sourced deal 0 to 100 against your documented buy box, before analyst time

✓Your existing Excel template is populated in minutes: no rebuilding per deal

✓Works alongside CoStar, Crexi, Reonomy, and Archer: the analysis layer on top of your sources

What To Look For

Six things that separate a deal sourcing platform that fills your funnel from one that helps you win.

Origination is only half the job. Evaluate a sourcing stack on how well it qualifies and underwrites the deals it brings in, not just how many it surfaces.

Automated Deal Intake

The platform should capture broker packages the moment they arrive. AcquiOS monitors your email for OMs, T-12s, and rent rolls and creates a structured deal record automatically, so nothing dies in an inbox and no deal is entered by hand.

Buy-Box Scoring

Sourced volume is worthless without triage. AcquiScore rates every deal from 0 to 100 against your documented buy box and returns a PROCEED or CAUTION recommendation before an analyst spends a minute, so the funnel self-prioritizes.

Instant Underwriting

The best sourcing platforms let you underwrite at the speed you source. AcquiOS extracts the T-12, rent roll, and assumptions with citation-level sourcing and populates your existing Excel template in minutes, with IRR recalculating live.

Searchable Deal Registry & De-Dupe

Every property your team touches should be searchable by address, seller, or type. AcquiOS keeps a full registry and runs conflict detection on every new deal, killing duplicate screens and duplicate broker outreach across analysts.

Assumption Validation

Sourcing a deal is not the same as trusting it. AcquiOS cross-references broker rent and expense assumptions against market comps and flags anything that diverges from evidence, so you qualify on reality, not the pitch.

Works With Your Origination Stack

A qualification layer should complement, not replace, your data tools. AcquiOS sits on top of CoStar, Crexi, Reonomy, and Archer: originate anywhere, then route the resulting OMs into AcquiOS for scoring and underwriting.

FAQ

CRE deal sourcing platforms: common questions.

What are the best deal sourcing platforms for commercial real estate?

CRE deal sourcing splits into two layers. Origination and data platforms - CoStar, Crexi, Reonomy, and Archer - surface on- and off-market properties, ownership data, and comps to fill your funnel. The intake and qualification layer decides which of those deals are worth analyst time: AcquiOS captures broker OMs directly from email, scores every deal against your buy box with AcquiScore (0-100), and underwrites in minutes. The best-run teams pair a data or origination platform for prospecting with AcquiOS for automated intake, qualification, and underwriting.

Is AcquiOS a deal sourcing platform?

AcquiOS is a deal intake, qualification, and underwriting platform rather than a prospecting or off-market data tool. It does not scrape ownership records or generate cold leads. What it does is turn the deals that already reach you - broker OMs in your inbox - into scored, underwritten, IC-ready opportunities automatically. It works alongside origination tools like CoStar, Crexi, and Reonomy, sitting between your deal sources and your investment committee.

What is the difference between a deal origination tool and a deal intake platform?

Origination tools (CoStar, Crexi, Reonomy) help you find opportunities - ownership data, listings, comps, and market signals. A deal intake platform like AcquiOS handles what happens after a deal arrives: it captures the OM, extracts and validates the economics, scores the deal against your buy box, and files it in a searchable registry. Origination fills the top of the funnel; intake and qualification determine which deals actually move forward.

How does AcquiOS score sourced deals against my buy box?

AcquiScore rates every sourced deal from 0 to 100 against your firm's documented buy box - asset type, market, size, return thresholds, and risk criteria - and returns a PROCEED or CAUTION recommendation before an analyst spends a minute on it. It extracts the deal economics from the OM, validates key assumptions against market comps, and surfaces the reasons behind the score so your team focuses effort on the opportunities that actually fit.

How does AcquiOS work with CoStar, Crexi, or Reonomy?

They are complementary. Use CoStar, Crexi, or Reonomy to originate and research opportunities; forward or upload the resulting broker OMs and financials to AcquiOS, which automatically creates the deal record, extracts the T-12 and rent roll, scores the deal against your buy box, and builds an underwriting model in your existing Excel template. AcquiOS becomes the qualification and analysis layer for everything your origination tools surface.

Which deal sourcing platform is best for a lean acquisitions team?

Lean teams get the most leverage from automating intake and qualification, because that is where analyst hours disappear. AcquiOS lets a small team screen far more sourced deals per week: broker OMs are captured from email automatically, scored against the buy box, and underwritten in minutes, so analysts only spend real time on deals that clear the bar. Pair it with a single origination or data source rather than stacking multiple prospecting subscriptions.
