Altus Group (RealNet/Insight) vs CoStar

CRE Market Data & Research Platforms · Verified 2026-08-22 · No paid placement

CRE valuation software, market analytics, and appraisal data (RealNet/Insight products), owner of ARGUS

Relevant to appraisers, valuation teams, and asset managers who need institutional-grade market analytics or still run ARGUS for cash flow modeling — Altus effectively owns the incumbent valuation-software category. The data depth (RealNet/Insight) is real, and ARGUS remains the appraisal-industry default for a reason. The honest caveat: ARGUS's interface and workflow feel dated next to newer modeling tools, pricing is enterprise-only, and teams that just need quick underwriting (not formal appraisal-grade output) will find it overbuilt for the job.

The #1 commercial real estate information, analytics, and marketing company

The default data backbone for any institutional CRE shop that can afford it — broad but expensive, and pricing is deliberately opaque, so it's a negotiated enterprise sale, not self-serve.
