CoStar Sales Comps review
A focused research tool for verified commercial sale comps, transaction details and trends.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
CoStar Sales Comps centers on independently verified commercial real estate transaction records. Brokers, appraisers, owners, investors and other property professionals can search 5.2 million sale comparables and review recorded details such as buyer, seller, broker, sale type, asking and achieved prices, sale date and time on market. The product is a fit when valuation work or commercial sales research depends on transaction-level evidence rather than a broad view of every real estate analytics workflow.
Its depth comes from linking sale records to related property context. Users can examine ownership history, deeds, tax assessments, loan structure and lending activity, along with property and submarket performance trends. Connections to tenants, vacancies and for-sale listings can help put transactions alongside other activity around a property. That makes it useful for researching dealmakers and comparing a sale with its surrounding market signals. The emphasis remains on commercial sale comparables, so teams whose priority is comprehensive market or portfolio analytics may find the scope too narrow.
CoStar sells access through a demo-based commercial offering, and its published Sales Comps page directs prospects to request a demo rather than showing a price list. The service is cloud-based, available on the web, and phone support is listed. This buying path suits mid-market and enterprise property teams evaluating a commercial data service through a sales conversation. Prospective buyers should assess fit around their valuation and transaction research needs; teams looking for a broader analytics suite or a self-directed purchase path should consider alternatives.
