Real Estate Asset Classes: NNN Leases, Multifamily, Self-Storage & Beyond

What Is a Triple Net Lease (NNN)?

A triple net lease is a commercial lease agreement in which the tenant pays all three major categories of property operating expenses in addition to base rent. Those three expense categories, referred to as the "three nets," are property taxes, property insurance, and common area maintenance (CAM). The structure shifts the majority of operating cost risk from the property owner to the tenant, creating a predictable stream of net income for the landlord.

In a standard triple net lease, the tenant pays base rent to the landlord on a monthly or quarterly basis. Separately, the tenant covers property tax assessments, building insurance premiums (including hazard, liability, and casualty coverage), and ongoing maintenance costs such as landscaping, parking lot upkeep, HVAC servicing, and general repairs. The landlord's income is largely insulated from fluctuations in operating expenses because those costs sit on the tenant's balance sheet. For a comprehensive deep dive, see our triple net lease guide.

Absolute NNN vs. Standard NNN

Not all triple net leases are created equal. In a standard NNN lease, the landlord may retain responsibility for major structural components, specifically the roof, foundation, and exterior walls. If the roof fails or the foundation develops problems, the landlord typically bears that cost.

An absolute NNN lease takes the structure further. The tenant assumes responsibility for every property expense, including roof replacement, structural repairs, and all capital improvements. Under an absolute NNN lease, the landlord's only obligation is to collect rent. These leases are most common with investment-grade national tenants that have the financial capacity to manage all building systems.

Who Uses NNN Leases

Triple net leases are the standard structure for single-tenant commercial properties occupied by national and regional tenants. Common NNN tenants include pharmacies (Walgreens, CVS), fast food restaurants (McDonald's, Chick-fil-A), dollar stores (Dollar General, Dollar Tree), auto parts retailers (O'Reilly, AutoZone), and convenience stores. Corporate office tenants and industrial tenants also frequently operate under NNN or modified NNN structures.

The prevalence of NNN leases in single-tenant retail is driven by the tenant's desire for operational control and the landlord's desire for predictable income. National tenants prefer to manage their own facilities to maintain brand standards, while property owners benefit from the elimination of operating expense variability. This alignment of interests makes the triple net structure the default for most single-tenant commercial transactions.

NNN vs. Other Commercial Lease Types

The triple net lease sits at one end of a spectrum. Understanding where it falls relative to other lease structures helps clarify why investors favor NNN for passive income. For a detailed comparison, see our guide on NNN vs. gross lease structures.

In a gross lease, the landlord pays all operating expenses and builds those costs into a higher rent. The tenant pays a single, all-inclusive amount. Gross leases are common in multi-tenant office buildings.

A single-net lease (N) requires the tenant to pay property taxes only. The landlord covers insurance and maintenance. A double-net lease (NN) adds insurance to the tenant's obligations, leaving only maintenance with the landlord. A modified gross lease splits expenses between landlord and tenant according to negotiated terms.

The triple net lease is favored by investors seeking the most passive ownership structure in commercial real estate. With operating expenses transferred to the tenant, the landlord's role in day-to-day property management is minimal. For this reason, NNN properties are sometimes described as "mailbox money," though this characterization oversimplifies the risks involved. Income depends on tenant performance, property condition, and market factors, and is never guaranteed.

Understanding where a specific lease falls on this spectrum is important during due diligence. The term "NNN" is widely used in commercial real estate marketing, but the actual allocation of expenses varies from one lease to the next. Investors should review the lease document carefully rather than relying on the NNN label alone.

Why Investors Choose Triple Net Lease Properties

Triple net lease properties appeal to a specific investor profile: those who prioritize income stability and low management involvement over aggressive appreciation. The structure offers several characteristics that make it attractive, particularly for retirees, 1031 exchange participants, and investors transitioning away from active property management.

Predictable income. Because the tenant covers property taxes, insurance, and maintenance, the landlord's rental income is largely fixed and predictable. The landlord is not exposed to rising property tax assessments or unexpected repair costs. This creates a relatively predictable income stream that many investors find appealing, though unlike bonds, real estate income is not guaranteed and depends on tenant performance and property conditions.

Minimal management responsibility. In a well-structured NNN lease, the tenant handles virtually all day-to-day property operations. There are no midnight calls about broken pipes, no contractor bids to evaluate, and no vacancy turns to manage. The operational burden falls on the tenant. Learn more about passive NNN investing through DSTs.

Long lease terms with built-in escalations. NNN leases typically run 10 to 25 years, providing long-term income certainty. Most modern NNN leases include contractual rent escalations, commonly structured as fixed annual increases (such as 2% per year or 10% every five years) or adjustments tied to the Consumer Price Index, often with a cap around 3%. These escalations provide a degree of inflation protection that fixed-income investments cannot match.

Credit tenant strength. Many NNN properties are leased to investment-grade national tenants. The creditworthiness of tenants like Walgreens, Dollar General, or McDonald's provides an additional layer of income security, though it does not eliminate risk entirely.

Favorable financing terms. Lenders view NNN properties with creditworthy tenants favorably. Long-term, fixed-rate financing at conservative loan-to-value ratios (typically 50% to 65%) is available for well-located NNN assets backed by strong tenants.

Risks and Considerations

NNN investing is not without risk, and investors should evaluate several factors carefully. For a thorough analysis of potential downsides, see our triple net lease risks guide and first-time NNN buyers guide.

Single-tenant concentration is the most significant concern. Income depends entirely on one tenant. If that tenant defaults, closes, or fails to renew, the property produces zero income until a replacement tenant is found.

Re-tenanting a single-tenant building can be difficult and expensive. Many NNN properties are built to the specifications of the original tenant, and converting them for a different use may require substantial capital investment.

Rent escalations, while helpful, may not fully keep pace with inflation over a 15- or 20-year lease term. An investor locked into 1.5% annual increases during a period of 4% inflation experiences real income erosion.

Property condition risk is another factor. If the tenant defers maintenance during the lease term, the landlord may face significant capital expenditure requirements when the lease expires. Periodic inspections and clear lease language regarding maintenance standards can mitigate this risk, but it requires attention.

NNN properties also tend to offer limited appreciation upside compared to value-add strategies like multifamily renovations or industrial repositioning. The trade-off is stability over growth potential.

Past performance does not guarantee future results. All investments carry risk, including the potential loss of principal.

NNN Lease Property Types: Sector Deep Dives

The NNN lease category encompasses several distinct property sectors, each with its own tenant dynamics, lease characteristics, and risk considerations. Investors evaluating NNN properties for sale should understand the differences between these sectors.

Pharmacy NNN (Walgreens, CVS)

Pharmacy properties have historically been among the most sought-after NNN investments. Lease terms typically span 20 to 25 years, and tenants like Walgreens and CVS carry investment-grade credit ratings. The locations tend to be high-traffic corner sites with strong real estate fundamentals independent of the tenant.

However, the pharmacy sector faces evolving headwinds. Changes in pharmacy benefit manager (PBM) reimbursement structures, the growth of mail-order prescriptions, and store rationalization programs have introduced uncertainty. Investors should evaluate remaining lease term, rental rate relative to market, and the long-term viability of the specific location when considering pharmacy NNN acquisitions.

Dollar Store NNN (Dollar General, Dollar Tree)

Dollar store operators have pursued aggressive expansion strategies, particularly in secondary and tertiary markets where other retailers have limited presence. Dollar General alone operates more than 20,000 locations across the United States. These properties typically feature lower purchase prices and moderate cap rates compared to other NNN sectors.

Lease terms for dollar store properties are generally 10 to 15 years with renewal options. The tenant base serves a value-conscious consumer demographic, providing a degree of recession resistance. Investors should note that dollar store locations in smaller markets may face limited re-tenanting options if the original tenant vacates.

Convenience Store and Gas Station NNN

Convenience stores and gas stations offer NNN lease exposure to essential-service retail. High foot traffic and daily-need products support consistent revenue for operators. Major chains and well-capitalized regional operators typically anchor these investments.

Environmental liability is the primary consideration unique to this sector. Properties with underground storage tanks carry potential remediation costs if contamination is discovered. Phase I and Phase II environmental assessments are critical during due diligence. Lease structures vary, and investors should carefully review which party bears environmental responsibility.

Fast Food and QSR NNN (McDonald's, Chick-fil-A)

Quick-service restaurant (QSR) properties are among the most competitive NNN assets in the market. Strong brand tenants, drive-through configurations, and recession-resistant business models make these properties highly attractive to investors. McDonald's and Chick-fil-A, in particular, command premium pricing due to their operational track records and tenant credit quality.

Lease terms vary by operator and whether the property is corporate-owned or franchisee-operated. Corporate-backed leases carry stronger credit, while franchisee leases depend on the individual operator's financial strength.

Auto Parts NNN (O'Reilly, AutoZone)

Auto parts retailers have demonstrated resilient performance through multiple economic cycles. The aging U.S. vehicle fleet supports both do-it-yourself (DIY) and do-it-for-me (DIFM) demand for parts and maintenance supplies. O'Reilly and AutoZone, the two largest publicly traded auto parts retailers, carry investment-grade ratings and maintain aggressive store expansion programs.

Lease terms for auto parts NNN properties are typically 15 to 20 years, with rent escalations structured at regular intervals. The essential nature of vehicle maintenance and the growing complexity of modern automobiles provide a supportive demand backdrop for the sector.

What Landlords Actually Pay in a Triple Net Lease

A common misconception is that NNN leases eliminate all landlord expenses. In practice, even in a standard triple net lease, the landlord may still be responsible for major structural repairs (roof, foundation, and exterior walls), capital expenditures at lease expiration, and re-leasing costs including broker commissions and tenant improvement allowances. For a detailed breakdown, read what landlords actually pay in a triple net lease.

Landlords should also plan for oversight and compliance monitoring. Verifying that the tenant is paying property taxes, maintaining adequate insurance coverage, and performing required maintenance protects the landlord from deferred liabilities that surface at lease end.

Multifamily Real Estate Investing

Multifamily real estate refers to residential properties with five or more units, encompassing garden-style apartment communities, mid-rise buildings, and high-rise towers. Multifamily investing benefits from a fundamental demand driver that few other property types share: people always need a place to live. For a deeper analysis, see our guide on understanding multifamily property classes for passive investment.

The multifamily investment thesis centers on diversified income streams, value-add potential, and demographic tailwinds. Unlike single-tenant NNN properties, a 200-unit apartment complex generates revenue from hundreds of individual leases. The loss of any single tenant has a marginal impact on overall income. Value-add strategies, such as unit renovations, amenity upgrades, and operational improvements, can drive rent growth and property appreciation.

Current Market Conditions (2025 to 2026)

Multifamily cap rates averaged 5.7% in 2025, unchanged from the prior year, and remain among the tightest of any major property type. National occupancy stood at approximately 94.6% as of November 2025. Rent growth has been uneven, with coastal markets and the Midwest posting modest gains while Sun Belt markets experienced weaker performance due to elevated new supply from the pandemic-era construction wave.

A significant shift is underway on the supply side. Construction starts declined approximately 74% from their 2021 peak by mid-2025. This pullback in new development is expected to support fundamentals over the next several years as existing supply is absorbed and new deliveries slow.

Class A, B, and C Properties

Multifamily properties are commonly classified by quality tier. Class A buildings are newer, well-located, and command premium rents. Class B properties are functional and well-maintained but may lack the finishes and amenities of Class A. Class C properties serve the affordable or workforce housing segment and often present the highest value-add opportunity alongside greater operational complexity.

Each classification carries a different risk and return profile. Class A tends to offer lower yields with greater stability, while Class C may provide higher cash-on-cash returns but demands more active management.

Multifamily and 1031 Exchanges

Multifamily is one of the most common replacement property types in 1031 exchanges. It is widely available through both direct ownership and Delaware Statutory Trust (DST) structures, giving investors flexibility in how they access the asset class.

Key risks include tenant turnover (typical apartment leases are 12 months), exposure to rent control legislation in certain jurisdictions, ongoing capital expenditure requirements for building systems and unit turns, and sensitivity to interest rate movements that affect both financing costs and property valuations.

Past performance does not guarantee future results. All investments carry risk, including the potential loss of principal.

Self-Storage Investing

Self storage investing involves the ownership and operation of storage facilities ranging from small drive-up unit complexes to large, climate-controlled buildings with hundreds of units. The asset class has attracted significant institutional capital over the past decade, drawn by its operational simplicity, low capital expenditure requirements, and resilient demand characteristics. Explore our guide to self-storage DST investments for a focused look at this sector.

The investment thesis for self-storage rests on several structural advantages. Operating costs are low relative to revenue because the product requires minimal maintenance, no unit finishes, and limited staffing. Demand is driven by life events that occur regardless of economic conditions: moving, downsizing, divorce, estate settlements, and small business inventory needs. This gives self-storage a degree of recession resilience that many other property types lack.

Current Market Conditions (2025 to 2026)

Self-storage cap rates for recent acquisitions have averaged approximately 5.25%, with stabilized properties trading in the mid-6% range. Occupancy rates among major REIT operators range from roughly 90% to 93%, with Extra Space Storage at 92.6% and Public Storage at 91.6% as of late 2025.

Same-store net operating income (NOI) growth has been mixed across the sector. Some operators have reported flat to slightly positive growth, while others experienced modest declines. The primary headwind is new supply. Approximately 2.5% of the national self-storage stock was under construction as of January 2026, and 71 million square feet of new space was delivered in the 12 months ending Q2 2025. This supply wave has pushed national vacancy rates to approximately 9%.

Growth Drivers

Population migration patterns, particularly movement to Sun Belt states and suburban areas, continue to generate storage demand. Urbanization trends, where households occupy smaller living spaces, create structural demand for supplemental storage. Small businesses increasingly use self-storage for inventory and equipment, adding a commercial demand layer.

Self-Storage and 1031 Exchanges

Self-storage is available as a 1031 exchange replacement property through both direct acquisitions and DST structures. DST availability in the self-storage sector has grown meaningfully in recent years, providing exchange investors with a passive entry point.

Key risks include oversupply in specific markets where construction has outpaced demand, low switching costs for tenants (making retention sensitive to pricing), and zoning and entitlement challenges that can complicate new development or expansion. Investors should also recognize that self-storage fundamentals are highly localized. A market with strong population growth and limited existing supply may offer attractive returns while a nearby market with excess capacity struggles with declining rents and occupancy.

Past performance does not guarantee future results. All investments carry risk, including the potential loss of principal.

Industrial Real Estate Investing

Industrial real estate encompasses warehouses, distribution centers, manufacturing facilities, flex and R&D space, and last-mile logistics hubs. The sector has been one of the strongest-performing commercial real estate asset classes over the past decade, driven by the structural growth of e-commerce and evolving supply chain strategies, though past performance does not guarantee future results. For a comprehensive analysis, see our industrial real estate investing guide.

The investment thesis for industrial centers on durable demand and favorable lease structures. E-commerce continues to require extensive warehouse and distribution networks, and supply chain reshoring and nearshoring trends have added a manufacturing demand component. Many industrial properties operate under NNN lease structures with terms of 10 to 15 years, providing the same passive income characteristics that attract investors to single-tenant retail NNN.

Current Market Conditions (2025 to 2026)

National industrial vacancy reached 7.6% in Q4 2025 after 13 consecutive quarters of increases. Vacancy is expected to plateau near 8% before declining as new construction deliveries slow. Rent growth decelerated to 1.3% year-over-year in Q4 2025, a notable moderation from the double-digit growth rates seen during the pandemic-era boom.

Cap rates for institutional-quality industrial assets have stabilized in the mid-5% to low-6% range, with core stabilized properties trading near 6%. Construction starts have declined approximately 70% from their pandemic peak, and development activity has shifted increasingly toward build-to-suit projects rather than speculative construction. This supply discipline should support fundamentals over the medium term.

Net absorption rebounded to approximately 177 million square feet in 2025, up 16% year-over-year, indicating that tenant demand remains healthy despite the moderation in rent growth.

Industrial Real Estate and 1031 Exchanges

Industrial properties are available as 1031 exchange replacement properties through direct acquisitions and DST structures. The NNN lease structures common in the sector appeal to investors seeking passive income with long-term lease certainty.

Key risks include tenant concentration (large industrial properties often rely on a single tenant), functional obsolescence if a building's specifications do not meet modern logistics requirements (clear height, dock configuration, truck court depth), and potential environmental liability depending on prior or current use.

Past performance does not guarantee future results. All investments carry risk, including the potential loss of principal.

Medical Office Investing

Medical office buildings (MOBs) are purpose-built or converted commercial spaces designed for healthcare delivery. Tenants include physician group practices, outpatient surgery centers, imaging and diagnostic facilities, and urgent care clinics. The sector occupies a distinct position among real estate asset classes, combining the income stability of long-term leases with the demand tailwinds of an aging population. For a focused look at this sector, read our medical office building investments guide.

The core investment thesis for medical office rests on tenant stickiness and GDP-resistant demand. Healthcare tenants invest significantly in buildout, often spending $80 to $150 per square foot or more on specialized equipment, plumbing, and configurations. That capital investment creates a strong incentive to remain in place, resulting in longer effective tenancies than most commercial lease terms would suggest.

Current Market Conditions (2025 to 2026)

Medical office has been one of the standout performers in commercial real estate. Average occupancy reached 92.5% to 92.7% in 2025, marking 17 consecutive quarters of occupancy growth. Cap rates averaged 5.5% to 6.9%, depending on property quality and lease profile, representing the first quarterly decline since Q2 2022.

Rent growth has been solid at approximately 2.4% year-over-year, with cumulative growth of 8.8% over the prior three years. By contrast, traditional office space has struggled with elevated vacancy rates in the range of 70% to 75% occupancy and cap rates of 8% to 10% or higher.

Supply constraints are reinforcing MOB fundamentals. The construction pipeline has fallen to historically low levels, with stock under construction declining 50% over five years. Over the most recent three-year period, absorption of medical office space has exceeded new completions, creating tightening conditions in many markets.

Medical Office and 1031 Exchanges

DST availability in the medical office sector has grown, providing 1031 exchange investors with access to institutional-quality healthcare properties. The recession-resistant characteristics of medical office appeal to conservative investors seeking stability.

Key risks include regulatory changes affecting healthcare reimbursement rates, tenant concentration in single-provider buildings, and the specialized nature of medical buildout that can limit re-tenanting options if a healthcare tenant vacates.

Past performance does not guarantee future results. All investments carry risk, including the potential loss of principal.

Comparing Asset Classes: Which Is Right for You?

The following table summarizes key investment characteristics across the major real estate asset classes covered in this guide. These figures represent general ranges based on current market conditions and should be treated as illustrative, not definitive. Actual performance varies significantly by property location, quality, tenant strength, and prevailing economic conditions.

Cap rate ranges are illustrative and reflect broad market averages. Individual property cap rates may fall outside these ranges depending on location, tenant credit quality, lease terms, and market conditions.

There is no single "best" asset class. The right choice depends on the investor's specific goals, risk tolerance, desired level of involvement, and exchange timeline. An investor prioritizing stable, passive income with minimal management may gravitate toward NNN retail or industrial properties with long-term leases. An investor willing to accept higher management intensity in exchange for appreciation potential and value-add opportunities may prefer multifamily.

For 1031 exchange investors, DST structures provide access to institutional-quality properties across all of these asset classes at significantly lower investment minimums than direct ownership typically requires. Allocating exchange proceeds across multiple DSTs in different asset classes and geographic markets is one strategy investors use to reduce concentration risk. Explore available opportunities in our investment marketplace.

Investors should evaluate their individual circumstances, consult with qualified financial and tax advisors, and review all offering documents carefully before making investment decisions. No comparison table can capture the full complexity of any individual property or market. These broad categories serve as a starting framework, not a substitute for property-level due diligence.

How Asset Classes Connect to 1031 Exchanges and DSTs

Section 1031 of the Internal Revenue Code allows investors who sell investment or business-use real estate to defer capital gains taxes by reinvesting the proceeds into like-kind replacement property. The exchange must follow specific IRS timelines: the investor has 45 calendar days from the sale of the relinquished property to identify potential replacement properties in writing, and 180 calendar days to complete the acquisition. For a full walkthrough of the process, see our complete 1031 exchange guide.

The like-kind requirement is broad. Any U.S. real property held for investment or business use qualifies as like-kind to any other U.S. investment or business real property. This means an investor selling an apartment building can exchange into NNN retail properties, industrial warehouses, self-storage facilities, or medical office buildings. The flexibility to move across asset classes is one of the most valuable aspects of the 1031 exchange framework.

Delaware Statutory Trusts as Replacement Property

Delaware Statutory Trusts (DSTs) qualify as like-kind replacement property for 1031 exchanges under IRS Revenue Ruling 2004-86. A DST holds title to real property and offers investors fractional beneficial interests in institutional-quality assets. DST investors receive their proportionate share of income and tax benefits without any property management responsibilities. Learn more in our DST learning hub.

DSTs provide 1031 exchange investors with several practical advantages. They allow investors to access property types and quality levels that would otherwise require significantly more capital. They accommodate precise dollar amounts, which helps exchangers meet the requirement to reinvest all proceeds. And they eliminate the management burden entirely, which is particularly valuable for investors who are retiring from active real estate ownership.

It is important to note that DST interests are securities. Investors should review the Private Placement Memorandum (PPM) and consult qualified legal and financial advisors before investing.

Matching Asset Class to Investor Needs

Many 1031 exchange investors split their proceeds across multiple DSTs in different asset classes and geographic markets. This diversification approach reduces exposure to any single tenant, property type, or local economic condition.

The appropriate asset class mix depends on individual goals. Investors prioritizing current income with minimal volatility may favor NNN retail and industrial properties with long-term leases and credit tenants. Those seeking a balance of income and appreciation potential may include multifamily and self-storage allocations. Conservative investors concerned about economic sensitivity may emphasize medical office and essential-service NNN tenants.

Regardless of strategy, investors should work with qualified financial advisors and 1031 exchange professionals to ensure compliance with IRS requirements and alignment with their broader financial plan.
