What is NNN Investing?
NNN, or "triple net," is a lease structure where the tenant pays not only the base rent but also three additional "nets": property taxes, insurance, and common area maintenance. This fundamentally changes the landlord-tenant relationship and the investment thesis.
In a traditional gross lease common in residential rentals, the landlord covers all costs and passes increases through rent adjustments. In NNN, the tenant bears these risks directly. This creates a more predictable cash flow for the investor and aligns the tenant's financial incentive with property maintenance.
How NNN Differs from Other Lease Types
Gross Lease
STRUCTURE
Landlord pays taxes, insurance, maintenance
LANDLORD
High operational burden
TENANT
Predictable total occupancy cost
Modified Gross
STRUCTURE
Costs split between landlord and tenant
LANDLORD
Shared burden, complex accounting
TENANT
Moderate cost responsibility
NNN (Triple Net)
STRUCTURE
Tenant pays base rent + taxes + insurance + maintenance
LANDLORD
Minimal operational responsibility
TENANT
Bears operational cost risk
What the Tenant Pays in an NNN Structure
Base Rent
The negotiated monthly rent payment
Property Taxes
Annual taxes based on assessed value
Insurance
Property, liability, and other coverage
CAM (Common Area Maintenance)
Parking lot, landscaping, common areas
Why NNN for First-Time Investors
NNN is the gold standard entry point for first-time commercial real estate investors because it combines simplicity, predictability, and professional management. Unlike residential rentals or development projects, NNN properties require minimal active management.

Three Reasons NNN Works for First-Time Investors
Predictable, Passive Income
Tenant pays rent directly into your account. No tenant calls, no maintenance headaches, no emergency repairs. The tenant bears operational risk.
Leverage and Scale
A $250K down payment on a $1M property means 4x leverage on your capital. This is difficult to achieve with residential rentals and impossible with stocks.
Tax Efficiency
Depreciation shields 25-35% of your annual cash flow from taxes. In a $50K year, you might only pay tax on $20K of income.
Understanding the Numbers
Every NNN deal lives and dies by the math. Understanding cap rates, cash-on-cash returns, and debt service coverage ratios is non-negotiable. Let's break down the key metrics.

Cap Rate (Capitalization Rate)
NOI ÷ Purchase Price
Shows the annual return on your total investment before financing. A 6% cap rate means you get 6% annual return on cash. Higher cap rates indicate more aggressive pricing or better fundamentals.
DSCR (Debt Service Coverage Ratio)
NOI ÷ Annual Debt Service
Shows how many times over your annual rent (NOI) covers your loan payments. Lenders require minimum 1.25x DSCR. A 1.50x DSCR means you have 50% cushion if NOI drops.
Cash-on-Cash Return
(Annual Cash Flow ÷ Cash Invested) × 100
Shows the actual return on the cash you put down (not financed). If you put $250K down and receive $20K in cash flow, that's an 8% cash-on-cash return.

Common Mistakes to Avoid
These are the mistakes we see first-time investors make repeatedly. Learn from others' errors before they cost you money.
What to Do Instead
Analyze lease escalations against historical tenant rent growth rates, verify they match or exceed expense inflation, and build sensitivity scenarios showing different tenant profitability under escalation scenarios.
