A Triple Net Lease, often called an NNN lease, is a commercial property lease agreement where the tenant pays more than base rent. The three “nets” are property taxes, property insurance, and maintenance or repair costs.
In a traditional rental arrangement, a landlord may collect rent and use part of that rent to pay operating expenses. In an NNN structure, many of those expenses are shifted directly to the tenant. That can include building repairs, common area maintenance, utilities, and sometimes structural items, depending on how the lease is written.
The word “triple” matters because all three major ownership burdens are typically passed through to the tenant. For landlords, that can reduce day-to-day management. For tenants, it means the rent number alone does not tell the full story.
The practical difference in net lease vs gross lease is who carries the operating costs.
In a gross lease, the tenant usually pays one fixed monthly rent amount, while the landlord pays property taxes, insurance, and many operating expenses. The rent may be higher because the landlord is building those costs into the price.
In a Triple Net Lease, the base rent is often lower, but the tenant pays additional costs separately. That can make monthly occupancy costs less predictable. For example, if insurance premiums increase or repairs are needed, the tenant may feel those costs directly.
This is why tenants should compare total occupancy cost, not just stated rent. A lower base rent can look attractive until the added charges begin arriving like guests who were not on the invitation list.
Investors are often drawn to net lease investment properties because they can provide predictable cash flow with less operational involvement. Many NNN leases are long term, often 10 to 20 years, and may include scheduled rent increases.
A single tenant net lease property can be especially appealing when the tenant is a national brand, pharmacy, bank, restaurant, or other business with strong credit. The landlord may have fewer maintenance calls, fewer operating decisions, and a clearer rent stream.
Still, the simplicity comes with concentration risk. If one tenant leaves, defaults, or closes that location, the landlord may suddenly have no rental income while still owing taxes, insurance, debt service, and re-leasing costs.
Tenants can be surprised by expenses that sit outside the base rent. These may include property taxes, insurance increases, repairs, utilities, landscaping, parking lot maintenance, roof work, HVAC repairs, and CAM charges (Common area maintenance).
Some tenants also underestimate professional costs before signing. Legal Fees and Transaction Costs can arise during lease review, negotiation, due diligence, financing, and future disputes.
Tax treatment also deserves attention. Depending on the structure, landlords may face limitations on certain deductions tied to active business involvement, including potential Section 199A issues. Tenants should also discuss deductibility with their tax advisor because lease payments and pass-through expenses may be treated differently depending on the business and facts.
Triple Net Leases often run 10 to 20 years, especially for national retail, restaurant, pharmacy, or bank tenants. Many include renewal options and scheduled rent increases, which can help landlords project long-term cash flow and help tenants secure location stability.
Yes. Tenants can often negotiate repair responsibilities, caps on expense increases, exclusions for structural repairs, renewal options, rent escalations, and audit rights. The most important point is to clarify exactly which costs pass through before the lease is signed.
A tenant may generally deduct ordinary and necessary business expenses, including rent and certain operating costs, but treatment depends on the facts. Repairs, improvements, taxes, insurance, and reimbursements can differ, so tenants should review the lease with a tax advisor.
Common NNN tenants include fast-food restaurants, pharmacies, banks, convenience stores, medical offices, dollar stores, auto service businesses, and national retailers. These businesses often want control over a location and are willing to handle property costs in exchange for long-term use.
