Best CRE Listing Platforms & Marketplaces (2026)

TL;DR

There's no MLS for commercial real estate, so where you list matters. LoopNet has the biggest audience, Crexi is the fastest-growing challenger with a real free tier, and CoStar is the data engine behind it all. For investment sales specifically, Real Capital Markets and Ten-X handle a huge share of institutional deal flow. Most brokers end up using two or three of these, not one.

LoopNet is the most heavily trafficked CRE marketplace in the US, with over 10 million unique monthly visitors. If you're marketing a property and want the widest possible net of tenants, buyers, and investors, this is where they're looking. Its listings also rank well in Google, which matters more than most brokers admit.

The business model is straightforward: basic listings are free and get minimal visibility, while paid tiers (Gold at roughly $200/listing/month up through Diamond at roughly $500) buy priority placement, video, and 3D tours. It's owned by CoStar Group, which gives it deep data backing but also makes it part of an ecosystem some brokers resent paying into.

Crexi is the fastest-growing challenger to the CoStar/LoopNet duopoly. Founded in 2015, it now hosts over 500,000 active listings representing more than $4 trillion in property value. The pitch: a genuinely free tier, a modern interface, and marketplace, analytics, and deal management rolled into one platform instead of three subscriptions.

The trade-off is inventory depth. In some markets Crexi's listing count still trails LoopNet, and institutional players tend to default to CoStar. But for independent brokers and smaller shops, free access to a serious marketplace is hard to argue with, and the premium tiers (Pro, plus an Enterprise tier with Crexi Intelligence analytics) are there when you outgrow it.

CoStar isn't a listing site you post to so much as the professional research platform behind the whole category. It maintains the largest CRE database in the US — building and ownership data, lease comps, sales transactions, market analytics — kept current by a research team of 1,000+ people, and serves over 150,000 CRE professionals. Listing on LoopNet gets you the audience; subscribing to CoStar gets you the intelligence.

It's on this list because for many brokerages the CoStar subscription and the listing strategy are one decision. It is also expensive — enough that solo brokers and small firms often can't justify it — and the platform's depth comes with a real learning curve and annual contracts.

Real Capital Markets (RCM), now part of LightBox, is where a huge share of institutional deals actually get marketed: over 50% of all US CRE sales are brought to market on RCM, and the platform has run more than $2.5 trillion in transactions across 76,000+ deals. It's a deal-marketing and document-room platform, not a public browse-and-search marketplace — listings go out to a database of 81,000+ qualified principals.

If you're selling investment property and want controlled, professional exposure to serious buyers, RCM is the standard. It doesn't do leasing or property management, and like most tools in this tier, pricing means talking to sales.

Ten-X, also owned by CoStar Group, is the online auction and transaction platform for CRE. Instead of listing a property and waiting, you take it to a scheduled auction with a broad buyer network competing in a transparent online process. The platform has facilitated billions in transactions and supports every CRE asset type.

Auctions aren't for every seller — you're trading pricing control for speed and certainty of close, and there are commissions and buyer premiums built into the model. But for the right asset (especially ones that need a definitive exit), it's a legitimately different channel from everything else on this list.

Brevitas is a network-driven investment real estate platform with 200,000+ global members and 350,000+ property listings created since its 2014 founding. Its angle is off-market and investment deal flow: listing is free, the member directory connects agents, brokers, and investors directly, and built-in email marketing and landing page tools handle the campaign side.

It doesn't have LoopNet's consumer traffic, and because anyone can list for free, listing quality varies. But as a zero-cost second channel for investment properties — plus branded enterprise platforms for brokerages — it earns its place in the stack.

TheBrokerList is different from everything above: it's a directory of CRE brokers, not properties. Founded in 2012 as the first online CRE broker directory, it gives brokers SEO-optimized profiles, listing syndication, a referral network across markets, and a content platform for blogging and podcasting.

It won't sell a building for you. But if your marketing problem is "clients and referral partners can't find me," a free profile here is one of the cheapest visibility plays in CRE, with paid membership unlocking syndication and enhanced profiles.
