Overview

What LoopNet does

LoopNet is a commercial property marketplace where owners and brokers list space for sale or lease and prospective buyers, tenants and investors search for free. Acquired by CoStar Group in 2012 for roughly $860 million, it now functions as the public-facing listing layer that feeds exposure both to general searchers and, because of the CoStar ownership, to CoStar own professional subscriber base of institutional investors and corporate real estate teams. The mechanism worth understanding is that a single listing, one payment, reaches two different audiences: the free public searchers on LoopNet itself, and paying CoStar professional subscribers, plus syndication to over 150 other sites. That dual reach is the actual sales pitch to brokers, not the free search feature consumers see. Paid tiers (Silver, Gold, Platinum ad packages) start at roughly $131 a month for Silver and scale up with more prominent placement and additional marketing tools. Buyers are commercial brokers and property owners paying to market listings, not the tenants and investors browsing for free. Because LoopNet and CoStar share ownership, a broker evaluating LoopNet advertising spend is implicitly also buying into the CoStar data ecosystem exposure, which is a meaningfully different proposition than an independent listing site would offer.

What people use it for

A broker wanting one listing to reach both general public searchers and CoStar professional subscriber base without a second payment
A property owner marketing a for-sale or for-lease asset who wants syndication across 150+ partner sites from a single listing
A tenant or investor searching for available commercial space for free without needing a paid account
A brokerage comparing LoopNet advertising spend against its overall CoStar data subscription, since both are owned by the same company

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about LoopNet.

LoopNet is owned by CoStar, the dominant CRE data provider, so paying for LoopNet placement indirectly reinforces a single company dominant position across both listings and data in commercial real estate.
Paid tiers scale from Silver at roughly $131 a month upward, and Gold and Platinum pricing is not published, making budget comparison against competitors like CREXi harder to do cleanly.
Because listing quality and exposure correlate with ad spend tier, owners and brokers who cannot justify higher tiers get less visibility even for genuinely strong properties.
As a marketplace dependent on the CoStar data ecosystem, any pricing, policy or antitrust exposure affecting CoStar Group (including the June 2026 price-fixing lawsuit naming major brokerages) has knock-on relevance for LoopNet advertisers.
Free searchers and casual browsers create high traffic volume that is not itself the paying customer, so lead quality for advertisers varies and includes non-serious enquiries.
