Guide to the best commercial real estate listings platforms

Quick take

The CRE listings landscape has consolidated significantly since 2023. CoStar Group now owns four of the major on-market platforms (LoopNet, Showcase, CityFeet, and Ten-X), Moody's has absorbed Catylist into its analytics platform, and the line between "listing site" and "marketing/distribution tool" has blurred. Meanwhile, the rise of off-market deal sourcing means many CRE professionals now pair an on-market listings site with an off-market intelligence platform like Reonomy.

This guide groups the major platforms by what they actually do, so you can pick the right tool — or the right combination — for your workflow.

At a glance:

Off-market intelligence

Reonomy

Most listings platforms cover what's actively being advertised for sale or lease — a small fraction of the total commercial property universe. Reonomy covers the rest.

Reonomy is a property and ownership intelligence platform that gives you access to data on every commercial, multi-family, and land asset in the United States — more than 54 million properties — whether or not they're on the market. You can filter by building characteristics, transaction history, and geography to surface assets likely to sell, then reach out directly to the true decision-makers behind LLCs and shell entities.

For brokers, investors, and service providers who don't want to compete for the same listings everyone else is seeing, Reonomy operates as a peer to (rather than a substitute for) the on-market platforms below.

Key stats:

• 54M+ commercial properties

• 68M+ property transactions

• 30M+ owner and contact records

• 5.2M+ companies

Generalist on-market marketplaces

The CoStar ecosystem: LoopNet, Showcase, CityFeet, and Ten-X

CoStar Group operates the most widely used set of CRE marketplaces in North America. Each property serves a slightly different audience, but they share inventory and listing infrastructure:

• LoopNet is the flagship marketplace and one of the most recognized CRE search engines, with roughly 500,000 listings and millions of monthly visitors. It covers office, multi-family, industrial, retail, land, hospitality, and specialty assets.

• Showcase is CoStar's professional-grade marketplace. Listings are free to post, with paid options for featured placement and custom profiles.

• CityFeet is positioned more toward the office, retail, and warehouse market, with historically stronger coverage in major metros (especially New York).

• Ten-X is now CoStar's auction platform, fully integrated with LoopNet. It handles online auctions and negotiated bids and has facilitated $24B+ in transactions since 2009.

If you list a property through CoStar, it can syndicate across this family — which means a single listing decision can put your property in front of the largest CRE audience online.

CREXi

CREXi is one of LoopNet's largest direct competitors, with more than 130,000 U.S. commercial properties listed for sale and a suite of tools to manage transactions from listing to closing. It has built a strong reputation among brokers as a faster-moving alternative to the CoStar family, and is one of the named national listing partners of RPR® (the NAR's commercial property resource).

Commercial Exchange (by Moody's, formerly Catylist)

Catylist was acquired by Moody's Analytics and now operates as part of Moody's CRE. Its public-facing marketplace, Commercial Exchange, is free to search and sources listings from 50+ local CRE platforms across North America — emphasizing verified, recently-validated data over raw volume. Listings also display Moody's proprietary Commercial Location Score. CRE professionals can post unlimited listings starting at $99/month.

Brevitas

Brevitas is a real estate marketplace (founded 2015, San Francisco) used by 45,000+ CRE professionals worldwide. It combines on-market, off-market, and private listings with built-in digital marketing tools — emails, branding, deal management — making it especially useful for investment sales teams. Free to join and post.

Biproxi

Biproxi started as a free listings platform and has since evolved into a CRE capital and auctions network, with a focus on connecting brokers with institutional investors. It's a strong fit for teams running larger or more complex deals where access to qualified capital matters as much as visibility.

QuantumListing

QuantumListing is a low-cost, social-media-friendly listings platform. Searching and browsing are free; posting starts at $79.99 per agent per year, with all listings treated equally regardless of membership level. It's a solid budget choice for individual brokers looking for additional visibility without a CoStar-tier subscription.

CIMLS (Commercial Investment Multiple Listing Service)

CIMLS is a large, all-asset-type CRE listings service with 370,000+ registered members. The basic plan is free for posting listings; a paid gold tier (~$20/month) unlocks additional images, document attachments, and lead-generation tools.

Total Commercial

One of the longest-running CRE listing services on the internet, Total Commercial bills itself as a full-featured listing platform without the high prices. It's also an RPR national listing partner. A reasonable choice for brokers who want broad visibility without a major monthly commitment.

RealNex

RealNex is a listings platform paired with a broader suite of CRE tools — CRM, marketing, data analysis, and prospecting all run from one dashboard. Search and listings are free; the integrated tooling is the paid product. Useful if you're consolidating tech vendors.

CommercialCafe

A general CRE information and listings provider covering office, industrial, retail, and coworking/shared spaces. Free for brokers to add listings, with paid options for property owners advertising directly.

Office, lease, and tenant-rep platforms

OfficeSpace.com

OfficeSpace.com specializes in office space — independent and coworking — and also lists retail, industrial, and land. It's one of the named national listing partners of RPR®, which gives its inventory wider reach than the site alone might suggest.

SquareFoot

SquareFoot is a polished office-space platform with national coverage but a heavier emphasis on 12 major metros (NYC, Chicago, LA, Houston, Dallas, Austin, San Diego, DC, Phoenix, Charlotte, Atlanta, Baltimore). About 10,000 listings; pricing is quote-based.

Rofo

Rofo has refined its positioning since 2023 and now focuses on helping businesses discover office, retail, industrial, flex, and coworking space across major U.S. markets. Coverage spans thousands of cities and works on a tenant/buyer-rep referral model — brokers and landlords get connected to qualified leads.

OfficeFreedom

OfficeFreedom is a global office space search engine with strong coverage in major international markets (London, NYC, Hong Kong, Toronto, Beijing, São Paulo, Paris, etc.) — 15,000+ offices listed. It operates as a broker rather than a pure search engine, taking a 10% success fee on leases.

Instant Offices

A worldwide office space marketplace covering general, shared, managed, and light industrial space. Like OfficeFreedom, it operates on a success-fee model rather than charging brokers upfront.

Regional and syndication platforms

Commercial Brokers Association (CBA)

CBA is a Pacific Northwest-focused CRE platform with strong inventory across eight counties in Washington and Oregon. With 4,000+ member brokers, 1,000+ member offices, and 13,000+ active listings, it's the go-to local resource if you operate in that region. Membership requires an application and a $350 setup fee plus monthly dues based on broker count.

Leavitt Digital (LDCRE)

LDCRE is a free, open-network listings platform with a unique angle: it syndicates listings into 900+ city-based news websites worldwide, dramatically increasing the local and global reach of any single listing. It's a complement to (not a replacement for) the major marketplaces — useful for brokers who want their listings to surface in long-tail local search results.

Digsy

Digsy has evolved into a hybrid product: a free listings marketplace combined with a CRE-focused CRM and AI tools for prospecting, follow-ups, and data automation. It's used by brokers at CBRE, JLL, Colliers, and Cushman & Wakefield. Free to list; CRM tools are the paid offering.

Classifieds and business marketplaces

Craigslist

One of the largest listing engines in the world, Craigslist has a substantial Office & Commercial section in every major U.S. metro. Listings are free, making it a strong resource for FSBO (for-sale-by-owner) commercial properties — though signal-to-noise varies widely by city.

BizBuySell

BizBuySell describes itself as the internet's largest business-for-sale marketplace, with 65,000+ businesses listed annually across food and restaurants, financial services, education, and other categories. It also offers broker matching and financing assistance for buyers. Seller pricing starts at $49.95 for six months.

PropertySend

PropertySend has shifted from a general marketplace toward CRE listing distribution and email marketing. If you already have listings live elsewhere, PropertySend helps push them to a national audience with targeted CRE distribution, real-time analytics, and prospect identification tools.

RealtyZapp

RealtyZapp is a multi-feature platform combining listings management, prospect tracking, email campaigns, and social marketing. Plans: Agent (free), Power Agent ($30/mo), Super Agent ($60/mo after a 30-day free trial).

Multi-family and residential crossover

Multi-family is the asset class where commercial and residential listings overlap. The big residential platforms all list duplexes, triplexes, and small apartment buildings, often with better consumer-facing UX than dedicated CRE sites.

Zillow

The most-trafficked residential platform in the U.S., Zillow lists plenty of multi-family properties for sale alongside its core single-family inventory. Worth checking for smaller multi-family deals.

Trulia

A Zillow-owned platform with a cleaner consumer interface. Useful for multi-family and small-unit residential income properties anywhere in the U.S.

Realtor.com

The MLS-backed residential platform. Beyond active listings, its "Just Sold" feature is useful for understanding recent comps in any given market.

Point2

Point2 primarily lists residential properties but offers commercial categories too — office, retail, industrial, coworking — making it a useful cross-shopping tool.

HotPads

A Zillow-owned rentals platform; not really a sales tool, but it can surface small multi-unit rental properties for analysis or owner outreach.

Land and specialty listings

LandSearch

LandSearch is one of the largest land marketplaces, with 10M+ acres listed across residential, commercial, agricultural, and recreational categories. Strong map-driven interface and dozens of filters. Free to list.

Land and Farm

Specializes in farmland, ranches, and commercial and residential land. 10M+ acres represented, organized by state.

LandWatch

A land-focused platform with 1M+ listings — hunting land, farms, ranches, homesites, and other land types.

Lands of America

Part of CoStar's listings family (alongside the broader Land.com network). Covers farms, ranches, country homes, and acreages nationwide.

MobileHomeParkStore.com

Mobile home and RV parks are an often-overlooked asset class. MobileHomeParkStore.com specializes in this niche — for-sale-by-owner, foreclosure, REO, seller-financing — across the country.

Which platform should you choose?

For most CRE professionals, the right answer isn't one platform — it's a combination.

• For on-market visibility, start with the CoStar family (LoopNet/Showcase) and CREXi. These cover the majority of actively-marketed inventory.

• For lease-focused work, layer in OfficeSpace.com, SquareFoot, or Rofo depending on your asset focus.

• For local depth, add the relevant regional platform (CBA in the PNW, Catylist's local networks elsewhere).

• For off-market deal sourcing — where most of the inventory actually lives — use Reonomy to find owners and properties before they hit any of the platforms above.

  
  

The CRE professionals winning in 2026 aren't the ones with access to the most listings. They're the ones who pair on-market visibility with off-market intelligence — and reach the right decision-makers first.
