Types of Commercial Leases: Gross, Net, NNN
By Khai Tran · · 5 min read
Most new commercial agents get overwhelmed by lease types, but the truth is each one follows a simple logic once you see the structure behind it. This guide breaks down Gross, Net, and NNN leases so you can speak confidently with investors and business owners.

Commercial leases feel intimidating when you’re new especially when clients expect you to explain things cleanly and confidently. The stakes are high: a client choosing the wrong lease structure can overpay for years. Your ability to simplify these lease types instantly positions you as the steady, strategic advisor they trust.
Below is a practical breakdown of the three most common commercial lease structures Gross, Net, and NNN plus an agent ready example you can plug into your next investor conversation.
What Commercial Leases Really Determine
Commercial leases decide who pays for what. Everything else is just structure around expenses.
Think in three layers:
- Base rent
- Operating expenses (OpEx)
- Risk and responsibility
The more expenses a tenant covers, the more predictable (and lower) the base rent tends to be. Once you see it this way, every lease type makes sense.
Gross Leases: Maximum Simplicity for Tenants
A Gross Lease often called a Full-Service Gross (FSG) lease, means the tenant pays one flat number. Landlord covers nearly everything else.
What Tenants Typically Pay
- One fixed rent amount
- Sometimes minor add-ons (parking, utility adjustments)
What Landlords Pay
- Property taxes
- Insurance
- Common area maintenance (CAM)
- Utilities
- Repairs
When Gross Leases Make Sense
- Office buildings
- Older buildings where landlords want leasing momentum
- Tenants who value predictability over complexity
How to Explain It to Clients (Simple Script)
“Think of a Gross Lease like an all-inclusive rate. You pay one predictable number, and the landlord absorbs the operating swings behind the scenes.”
Net Leases: Splitting Costs with Clarity
A Net Lease introduces shared responsibility. The tenant pays base rent plus one or more expense categories.
Three Subtypes
- N Lease (Single Net): tenant pays property taxes
- NN Lease (Double Net): tenant pays taxes and insurance
- NNN Lease (Triple Net): tenant pays taxes, insurance, and CAM
Net leases shift some operating volatility to the tenant, which means your investor clients often like them.
NNN Leases: The Investor Favorite
A Triple Net (NNN) lease is the most investor friendly and the most tenant responsible.
What Tenants Pay
- Base rent
- Property taxes
- Building insurance
- CAM (repairs, maintenance, landscaping, janitorial, etc.)
Why Investors Love Them
- Predictable, low-touch ownership
- Pass-through expenses reduce risk
- Long-term stability when paired with credit tenants (ex: CVS, Dollar General, Starbucks)
Why Some Tenants Prefer NNN
- Lower base rent
- Clearer transparency in what they’re paying for
- More control over property conditions
How to Compare the Three Quickly
| Lease Type | Tenant Pays | Landlord Pays | Best For |
|---|---|---|---|
| Gross | One fixed rent | Most expenses | Office tenants wanting simplicity |
| Net (N) | Rent + property taxes | Insurance, CAM | Smaller retail/office |
| Net (NN) | Rent + taxes + insurance | CAM | Retail, industrial |
| NNN | Rent + taxes + insurance + CAM | Structural items only | Investors, national tenants |
Real Example: How to Explain Lease Structures to an Investor
Here’s an email you can use with an investor evaluating a retail property:
Investor Email Template
Subject: Quick Breakdown of Lease Structure on the Main St. Retail Listing
Hi [Investor Name],
Here’s a clean summary of the lease structure on the Main St. property:
- The tenant is on a NNN lease, which means they cover taxes, insurance, and CAM.
- Landlord responsibilities limited to structure and roof, which keeps operating expenses predictable.
- Current NNN reimbursements are $6.40/SF, aligned with similar product in this submarket.
- Effective cap rate after verified reimbursements lands at 6.2%, which is strong for this tenant profile.
Let me know if you want a rolled-up cash flow or a cash-on-cash estimate based on your financing assumptions.
Best, [Your Name]
How to Teach Lease Types to Clients Without Overwhelming Them
Use the “Three-Box Method”
Create three boxes on a notepad:
- Base Rent
- Taxes + Insurance
- Maintenance (CAM)
Then check which boxes the tenant pays.
Why This Works
Clients understand faster when they can see the responsibility shift. This method removes jargon and builds your authority without being technical.
Lease Type Red Flags Agents Should Watch For
1. CAM Caps That Don’t Actually Cap Anything
Some caps exclude controllable expenses, clarify this early.
2. Old Buildings with “NNN-Style” CAM
If there’s deferred maintenance, tenants may push back or demand concessions.
3. Gross Leases Priced Too Low
The landlord might be quietly absorbing unprofitable OpEx.
4. Leases Without Reconciliation Language
This creates disputes later, always check.
How to Advise an Introverted Agent Client on Explaining Leases
Sometimes your client is the agent, not the tenant or investor. Introverted agents often fear sounding inexperienced.
Three Simple Lines to Build Their Confidence
- “Here’s the simplest way to think about this lease…”
- “Let me break this into what you pay and what the landlord pays.”
- “Tell me what matters more to you: predictability or control?”
These lines guide the conversation and reduce pressure.
When to Recommend Each Lease Type
Gross Lease → Recommend when:
- Tenant wants cost certainty.
- Building OpEx is stable and predictable.
- Landlord wants to simplify marketing.
Net or NNN Lease → Recommend when:
- Investor wants stable, low-touch ownership.
- Tenant prefers transparency and control.
- Property is newer with clean financials.
Quick Recap for Agents
- Gross = simplicity for tenants; risk on landlord.
- Net = shared costs; moderate landlord risk.
- NNN = tenants carry most costs; stable for investors.
When in doubt, draw the “three boxes” and show who owns each cost. It’s the fastest path to clarity.
