Where to List Commercial Property for Free
Where an owner or broker can list commercial property without paying, what each marketplace charges for, and how to reach buyers and tenants.
Updated
You can list commercial property for free on SPACEXPLORATION, the free MLS for commercial property: no listing fee, no subscription, and no commission on the deal, whether you are a broker or the owner. Crexi also lets you list for free, but charges for higher placement and full lead details. LoopNet does not offer free listings, and CoStar and Moody's CRE charge to list or to look. SPACEXPLORATION asks for no exclusivity, so you can list there free and still pay for exposure elsewhere if you decide you need it.
What the big marketplaces charge for
Most commercial listing sites earn their money from the people listing, so "free" usually means a basic listing with the useful parts sold separately. Here is what each one charged when we checked their published terms in October 2026:
| Marketplace | Can you list for free? | What costs money |
|---|---|---|
| LoopNet | No. Its FAQ says you cannot list there for free. | Every listing goes through its ad sales. Paid tiers rank first, and its top ad tiers run at least six months. |
| Crexi | Yes. | Higher search placement, full lead contact details, and its AI tools come with paid plans. |
| CoStar | It is a research subscription. | Seeing the listings inside it takes a paid subscription. |
| Moody's CRE | No. | Listing on its marketplace costs $99 a month. |
| SPACEXPLORATION | Yes. | Nothing. Listing, searching, and the leads cost nothing. |
Prices and plans change, so each comparison page links the sources it was built from and the date we read them.
What a free listing should include
A free listing is only worth having if it reaches people and lets them reach you. Before you settle on a marketplace, check four things:
- Who can see it. A listing behind a paywall or a sign-up wall reaches fewer buyers. On SPACEXPLORATION a live listing is public on the web, on the map, and to AI assistants, and nobody needs an account to see it.
- How it ranks. If others can pay to sit above you, your free listing sinks. SPACEXPLORATION has no paid tiers or promoted spots; results sort newest first, or by the sort the searcher picks.
- Whether you get the lead. Some sites hide the inquirer's contact details until you pay. On SPACEXPLORATION every inquiry arrives in your email with the buyer's name, email, phone if they gave one, and message.
- What it locks you into. Look for a minimum term or an exclusivity clause. SPACEXPLORATION has neither: your listing stays up until you take it down, and you can list the same property anywhere else.
Where buyers and tenants look now
Buyers still search listing sites, but more of them now start by asking an AI assistant such as ChatGPT or Claude. An assistant can only recommend a listing it is able to read. SPACEXPLORATION is built to be read by them: every live listing is searchable from Claude, ChatGPT, and other AI assistants, so a buyer who asks one for a property like yours can get yours back. AI assistants explains how that works.
The other free channels still matter, and none of them conflicts with a marketplace listing:
- Your own website. Put the listing on the building's or your brokerage's site.
- A sign on the property. Local tenants and owner-users drive past it every day.
- Your network. Send the listing link to brokers, neighbors, and past inquirers.
- Local economic development groups. Many keep a list of available sites for companies looking to move into the area.
How to list on SPACEXPLORATION
- Create an account. There is nothing to pay for, so signing up does not ask for payment details.
- Start a listing. Choose sale or lease, then add the address, photos, a headline, and a short summary. Have a flyer or offering memorandum? Upload the PDF and the built-in assistant drafts the listing from it for you to check.
- Fill in what buyers filter on. Property type, size, price or rate, and the building facts that matter for its type, like clear height for a warehouse or frontage for retail. What to put in a commercial property listing goes through them one by one.
- Verify your email and phone, then publish. The verification keeps fake and spam listings out of the market, and your number goes on the listing's contact card so buyers can call you.
To publish, a listing needs at least one photo (every photo passes an automatic content check), a headline, a geocoded street address, a summary of at least 80 characters, three highlights, and either an asking price (or "price upon request") for a sale or at least one available suite with its size and rate (or rate on request) for a lease. The editor's checklist shows what is still missing.
If you would rather not do it yourself
Email your offering memorandum, flyer, or photos to list@spacexploration.com. We set up the listing at no charge and send it back for you to approve before it goes live. Or start your listing yourself.
