TenantBase vs. Listing Sites: Which Should You Use to Find Commercial Space?
Listing sites or a tenant rep broker? Who represents you, what each costs, and when to use each to find and lease commercial space.
Use listing sites to research the market or a specific building. Use TenantBase when you are ready to find and lease a space. Both are free for tenants.
- Use a listing site to browse inventory on your own, research a specific building, or pre-screen buildings if you already have a tenant rep broker.
- Use TenantBase when you want someone on your side negotiating rent, free rent, tenant improvement allowance and renewal terms, at no cost to you.
Commercial listing sites are marketplaces where landlords and their brokers advertise available space. TenantBase also has searchable listings from the local brokerage community, but it is a matching platform: it connects you with a local partner broker who represents you. You keep the self-serve browsing of a listing site and add someone on your side.
Who do you talk to when you inquire on a commercial listing?
Usually the landlord's listing broker, whose job is to get the best deal for the property owner. Think of a car dealership: the salesperson will help you get a car, but they work for the dealership. A listing broker will help you lease space, but they work for the landlord unless you explicitly agree otherwise, and anything you share about your budget or timeline can shape the landlord's offer.
A listing broker will also show you their building, not the other buildings that might fit you better. Your own tenant rep can take you anywhere in the market. TenantBase is not a middleman in your deal: it sends you matching spaces, introduces you to a tenant rep broker who fits, then steps aside. Brokers are almost always paid by the landlord at signing, so representation costs you nothing out of pocket. For the full picture, see how tenant representation works.
Why does broker fit matter?
Commercial real estate is specialized. Some tenant reps focus on 50,000 SF headquarters moves, others on industrial, retail or medical space, and most work a specific set of submarkets. A broker built for large corporate leases may not have the time or focus for a 3,000 SF office search. The right fit regularly works your space type, size and submarket, and treats your lease as a priority. That is what TenantBase matches on. For questions to ask, see Finding the Right Fit for Your Business.
How does the search work on each, step by step?
The example: a 25-person company leasing about 5,000 SF of office space in a major U.S. city, moving in 6 to 9 months out. Here is what you do yourself on each path.
| Stage | On listing sites, you... | With TenantBase, you... |
|---|---|---|
| 1. Define the need | Set filters for city, space type and size. A free account adds saved searches and alerts. | Fill out a short sign-up (about 2 minutes) with your size, submarket, budget and timing, and get matching alerts. |
| 2. Build a shortlist | Scroll listings and compare photos and asking rents. | Browse and save favorites, and get introduced to a local partner broker who builds a market survey, including spaces you may not see online. |
| 3. Make contact | Inquire on each listing. Each one reaches that building's listing broker, who represents the landlord. | Share your favorites with your broker, who handles communication with landlords and listing brokers for you. |
| 4. Tour | Schedule tours one building and one listing broker at a time. | Tour a curated set of spaces in one block of time, with your broker asking the hard questions. |
| 5. Negotiate | Negotiate rent, free rent, TI allowance and escalations yourself. | Your broker sends proposals to several landlords at once and negotiates using recent comparable deals. |
| 6. Sign | Review the lease with your attorney. | Your broker and attorney review the lease together. |
| 7. After move-in | Track escalations, operating expenses and renewal dates on your own. | Your broker can help review escalations and expense reconciliations and plan renewals. |
Both paths let you browse and reach out on your own. The difference is that TenantBase adds a local broker who takes steps 2 through 7 off your plate.

How do commercial listing sites make money?
From the listing side. Across the largest U.S. commercial listing sites, landlords and listing brokers pay for visibility through tiered listing packages or broker subscriptions, paid listings rank higher, and inquiries route to the listing broker. No one on the site represents the tenant, so the first spaces you see are often the ones with the biggest ad budget, not the best fit.
How much does each option cost?
Your out-of-pocket cost is $0 either way. The difference shows up in the lease you sign and the time you spend. On a 5,000 SF, 5-year lease at $40.00/SF/year (about $1,000,000 in rent before escalations), here is what common improvements are worth:
| Lease term | Example improvement | Value over the lease |
|---|---|---|
| Free rent | 1 extra month | $16,667 |
| Annual escalations | 2.5% a year instead of 3% | About $10,561 |
| TI allowance | $5/SF more from the landlord | $25,000 |
| Operating expenses | $1/SF a year capped or excluded | $25,000 |
| Renewal option | Renewal rate $4/SF below market | $20,000 per renewal year |
Illustrative math, not a promise of savings. Concessions depend on the market, the building and your timing. Landlords typically budget broker commissions into the deal and pay them at signing. For the clauses that cost tenants the most, see 8 lease red flags to negotiate.
Already searching on a listing site? How to bring in a tenant rep
You do not have to pick one. Browse listing sites to learn the market, then bring your favorites to your TenantBase partner broker.
- Save your shortlist with addresses and suite numbers. Your broker can pursue any of them.
- List every listing broker you have contacted to avoid confusion over who introduced which space.
- Bring in your broker before you sign a letter of intent, which can limit what they can negotiate.
- Share your timeline and budget: lease expiration, move-in date, headcount and target rent.
- Confirm in writing how your broker is paid on your deal.
