Net Lease

What Is a Net Lease?

A net lease is a commercial lease structure in which the tenant pays some or all of the property's operating expenses in addition to base rent. Net leases shift financial responsibility from the landlord to the tenant, making them among the most passive forms of real estate investment. There are three tiers of net lease: single net (N), double net (NN), and triple net (NNN), each shifting progressively more expenses to the tenant.

The Three Net Lease Structures

In a single net lease (N), the tenant pays base rent plus property taxes. The landlord remains responsible for insurance and maintenance. In a double net lease (NN), the tenant pays base rent plus property taxes and insurance. The landlord handles maintenance and structural repairs. In a triple net lease (NNN), the tenant pays base rent plus property taxes, insurance, and all maintenance costs. The landlord's only responsibility is structural integrity, and even that is sometimes passed to the tenant in an absolute NNN lease.

NNN: The Most Passive Investment

Triple net leases are the gold standard for passive real estate investment. With the tenant covering taxes, insurance, and maintenance, the landlord's role is reduced to collecting rent and occasionally managing the building's structure. Many NNN investors describe their properties as "mailbox money" because their primary activity is depositing rent checks. This passivity makes NNN properties especially attractive to retirees, busy professionals, and investors seeking hands-off income.

Tenant Credit Quality

In net lease investing, the creditworthiness of the tenant is paramount. A NNN lease is only as valuable as the tenant's ability and commitment to pay. Investment-grade tenants like national pharmacy chains, fast food franchisees, dollar stores, and medical practices backed by large health systems provide the most reliable income. The stronger the tenant's credit, the lower the risk, and correspondingly the lower the cap rate.

Cap rates on NNN properties with investment-grade tenants typically range from 4-6%, while NNN properties with local or less creditworthy tenants may trade at 7-9%. The spread reflects the risk difference: a Walgreens-backed 15-year NNN lease is far more reliable than a local restaurant on a 5-year NNN lease.

Common in Commercial Real Estate

Net leases are predominantly a commercial real estate structure. They are standard in retail, industrial, medical, and office properties. Residential leases are almost always gross leases where the landlord pays operating expenses. For investors transitioning from residential to commercial, understanding net lease structures is essential because they fundamentally change how you analyze and compare properties.

Investment Considerations

When evaluating net lease properties, focus on tenant credit quality, lease term remaining, rent escalation clauses, and location. Longer lease terms with built-in annual rent increases provide the most predictable long-term income. Properties in strong locations with good demographics are easier to re-lease if the current tenant vacates. Net lease investing rewards patience and thorough due diligence with some of the most consistent and passive income in real estate.
