Net lease real estate has long been a favored asset class among institutional investors, family offices, and high-net-worth individuals seeking predictable, bond-like income with real property as collateral. In a net lease structure, the tenant — rather than the landlord — is responsible for some or all of the property's operating expenses, including taxes, insurance, and maintenance. The result is a passive income stream with minimal management burden.
But the simplicity of the concept masks meaningful complexity in execution. Not all net lease properties are created equal, and the difference between a well-underwritten deal and a poorly structured one can be the difference between a decade of reliable income and a costly workout.
Understanding the Lease Structures
The three primary net lease structures are the single net (N), double net (NN), and triple net (NNN) lease. In a single net lease, the tenant pays base rent plus property taxes. In a double net lease, the tenant covers taxes and insurance. In a triple net lease — the most common structure in institutional net lease investing — the tenant assumes responsibility for taxes, insurance, and maintenance, leaving the landlord with a truly passive position.
A fourth structure, the absolute net or "bondable" lease, goes further still: the tenant is responsible for all costs under any circumstance, including structural repairs and rebuilding after a casualty event. Absolute net leases are most commonly found with investment-grade tenants such as major pharmacy chains, quick-service restaurants, and convenience store operators.
Tenant Credit Is the Foundation
In a net lease investment, you are effectively making a credit bet on the tenant. The property is the collateral, but the income stream depends entirely on the tenant's ability and willingness to pay rent over the full lease term. This is why tenant credit analysis is the most important step in any net lease underwriting process.
Investment-grade tenants — those rated BBB- or higher by S&P or Baa3 or higher by Moody's — command the lowest cap rates (highest prices) because their probability of default is low and their leases are typically long-term with contractual rent escalations. Sub-investment-grade and unrated tenants can offer higher yields, but require deeper diligence on unit-level economics, brand health, and operator quality.
Lease Term and Rent Escalations
The remaining lease term at acquisition is a critical value driver. A 20-year absolute net lease with an investment-grade tenant trades at a meaningfully lower cap rate than the same property with five years remaining. As the lease term shortens, the property's value increasingly reflects its real estate fundamentals — location, replacement cost, and alternative use — rather than the income stream.
Rent escalation provisions also matter significantly. Fixed bumps of 5–10% every five years, annual CPI-linked escalations, or flat leases with no escalations all produce materially different long-term returns. In an inflationary environment, the difference between a flat lease and a CPI-linked lease can compound into a substantial gap in real income over a 15-year hold.
Location and Real Estate Fundamentals
Even the most creditworthy tenant can vacate at lease expiration. When underwriting a net lease acquisition, investors should always ask: if this tenant leaves tomorrow, what is this property worth and who would occupy it? Properties in dense, high-traffic corridors with strong demographic profiles and limited competing supply have the best re-leasing prospects. Isolated, single-use properties in secondary markets with limited alternative tenants carry meaningful residual risk.
Cap Rate Dynamics in the Current Environment
Net lease cap rates are sensitive to interest rates, as the asset class is often compared to long-duration fixed income. When the 10-year Treasury rises, net lease cap rates tend to follow — though the relationship is not perfectly correlated and varies by property type, tenant credit, and lease structure. Investors who purchased net lease assets at historically compressed cap rates in 2020–2022 have faced mark-to-market pressure as rates have risen. Conversely, the current environment presents selective acquisition opportunities for investors with patient capital and strong underwriting discipline.
NorthStar's Approach
NorthStar Finance focuses on net lease acquisitions and development in the healthcare and essential retail sectors, where tenant demand is driven by demographic tailwinds and service-oriented businesses that are resistant to e-commerce disruption. We prioritize properties with strong real estate fundamentals, long initial lease terms, and tenants with transparent unit-level economics — regardless of whether they carry a formal credit rating.

For investors seeking to build or expand a net lease portfolio, the current environment rewards discipline over volume. The best net lease investments are made when the real estate, the tenant, and the lease structure all align — and that combination is worth waiting for.
