Lease structure matters more than most sellers realize. Two buildings with the same gross rent can have wildly different values depending on whether the leases are NNN, modified gross, or full service. And most buyers (including me) have a strong preference.

Featured takeaway

NNN Leases Are Worth 0.5-1% in Cap Rate Premium — That’s $200K+

A building with NNN leases trades at a lower cap rate (higher price) than the same building with gross leases. Converting before you sell can add substantial value.

Why Buyers Price NNN Higher

NNN shifts all expense risk to tenants. If property taxes or insurance spike, buyers’ NOI doesn’t change. That predictability justifies a lower cap rate and higher purchase price.

The Gross Lease Trap

If you’re collecting $12/SF in rent but paying $4.50/SF in expenses, your real NOI is $7.50/SF. Buyers underwrite at $7.50, not the gross rent figure.

The Gap in Practice

Two similar buildings in Raleigh or Greenville might value at 7% cap (NNN) vs. 7.5-8% cap (modified gross). On $150K NOI, that’s a $200K-$300K difference.

Escalation Clauses Matter

Escalation Clauses Matter

Gross leases without expense escalation mean your NOI shrinks every year. That’s a red flag for buyers and justifies a higher cap rate (lower price).

Bottom line: NNN leases typically sell at a 0.5-1% lower cap rate than gross leases. On a $150K-producing building, that’s $200K-$300K in value. Structure matters.

Lease Structure Check: Review whether your leases are NNN, modified gross, or full gross.
Expense Reality: Calculate your true NOI by backing out all actual operating expenses you pay.
Escalation Gaps: Leases without escalation clauses lose value over time as taxes and insurance rise.
Conversion Timeline: If not selling immediately, converting to NNN at tenant renewal is worth exploring.

Quick definitions

NNN (triple net): Tenant pays base rent plus their share of property taxes, insurance, and common area maintenance. The landlord collects rent and the tenant covers the operating expenses. The rent you see is basically your NOI (minus management and reserves).

Quick Lease Structure Questions

Buyers care deeply about who bears the expense risk. Answer these questions to understand your building’s cap rate risk:

Are most or all leases NNN, or split between NNN and modified gross?
Do your gross leases have expense escalation clauses that reset annually?
What percentage of your NOI goes to tenant improvements and leasing commissions yearly?
Have your expenses grown faster than your rents over the last 3-5 years?

Modified gross: Tenant pays a flat rent that includes some expenses but not all. The landlord might cover property taxes while the tenant pays insurance and CAM. Or the landlord covers everything up to a base year and the tenant pays increases above that. There are a million variations.

Gross (full service): Tenant pays one number and the landlord covers everything. Taxes, insurance, maintenance, utilities, sometimes even janitorial. Common in office. Less common in industrial but I see it occasionally.

Why NNN is king for value

Buyers love NNN leases because the income is predictable and the expense risk is on the tenant. If property taxes go up 20%, that’s the tenant’s problem on a NNN lease. If insurance doubles, same thing. The landlord’s NOI stays the same (or grows with rent bumps).

A building with NNN leases will almost always trade at a lower cap rate (higher price) than the same building with gross leases. Because the income is more certain and the expense risk is lower.

I see this play out in Raleigh retail and Greenville flex constantly. Two similar buildings, similar rent levels, but one is NNN and one is modified gross. The NNN building might trade at a 7 cap. The modified gross building at a 7.5 or 8 cap. On a building with $150K NOI, that difference is $200K-300K in value. Just based on lease structure.

The gross lease trap

If you have gross leases and your expenses have been climbing (and let’s be honest, whose haven’t), your actual NOI might be a lot lower than it looks. You’re collecting $12/SF in rent but paying $4.50/SF in expenses. Your real NOI is $7.50/SF. A buyer is going to underwrite based on that $7.50, not the $12.

Thinking about selling?

Get a confidential opinion of value. No obligation.

And here’s the kicker: if your lease doesn’t have expense escalation clauses, your NOI is actually going down every year as taxes and insurance go up. That’s a problem for value.

What you can do about it

If you’re not selling immediately, try to convert your leases to NNN at renewal. Most commercial tenants in the Carolinas are used to NNN in industrial and flex. It’s the market standard. You might need to lower the base rent slightly to compensate, but the net effect on your building’s value at sale will be positive.

If you’re selling now with gross leases, that’s fine. I buy buildings with all kinds of lease structures. I just price them accordingly. The important thing is that I see the real expenses so I can underwrite the actual NOI.
