Single Tenant Net Lease Explained: STNL, Cap Rates, and What to Abstract

A single tenant net lease (STNL) is a commercial property occupied by one tenant on a net lease, where that tenant pays some or all of the property taxes, insurance, and maintenance on top of base rent. Because there is only one tenant, the building is either 100% leased or 100% vacant, so the whole investment rides on that tenant's credit and the length of the lease. Investment-grade credit tenants on long absolute net leases trade at lower cap rates (higher prices) than franchisee-operated stores on shorter terms.

STNL is one of the simplest structures in commercial real estate to describe and one of the easiest to underwrite badly. A clean cover page hides go-dark clauses, roof and structure carve-outs, and rent bumps that do not keep pace with anything. This guide covers what the term means, how the cap rate is set, why buyers like it for a 1031 exchange, and what to pull out of the lease first.

What is a single tenant net lease?

A single tenant net lease is a lease of an entire property to one tenant on net terms, meaning the tenant reimburses or directly pays operating costs such as property taxes, insurance, and maintenance instead of the landlord absorbing them. The landlord collects rent closer to net income, which is why these deals are quoted on cap rate. Typical terms run 10 to 25 years with scheduled rent bumps and a corporate or franchisee guaranty behind the payments.

Think of a standalone pharmacy, a quick-service restaurant pad, a dollar store, or a bank branch. One tenant, one building, one rent check. The economics depend far more on who signed the guaranty and how long they are committed than on the dirt itself.

What is the difference between single tenant and multi tenant net lease?

The core difference is vacancy risk and management load. A single tenant property is binary: it is fully occupied or fully empty, and one lease drives all of the income. A multi-tenant net lease property, like a strip center, spreads income across several tenants, so losing one hurts but does not zero out cash flow, at the cost of more active management and shared common area accounting.

Single tenant deals are usually more passive: one tenant to track, one estoppel to collect, and often a triple net structure that pushes operating expenses to the tenant. Multi-tenant deals require CAM reconciliations, pro rata share math, and re-leasing plans as suites roll. Both use net lease mechanics, so it helps to understand the underlying double net and triple net structures before comparing the two property types.

What does STNL mean in real estate?

STNL stands for single tenant net lease, and it is used as shorthand for the whole asset class of one-tenant net-leased properties. When a broker markets an "STNL pharmacy" or an "STNL QSR pad," they mean a freestanding building leased to a single operator on net terms. The acronym shows up in offering memoranda, listing sites, and 1031 exchange marketing.

STNL overlaps with the labels "net lease" and "credit tenant lease," but they are not identical. STNL describes the tenant count and the lease type. It does not by itself tell you the credit of the tenant or whether the lease is absolute net, so you still have to read the document.

What is a good cap rate for a single tenant net lease?

A good cap rate for a single tenant net lease is the one that fairly prices the tenant's credit, the remaining lease term, the rent bumps, and the location, so there is no single correct number across the market. The cap rate falls (price rises) when the tenant is investment-grade, the term is long, the lease is absolute net, and the site is strong. It rises when the guaranty is a franchisee, the term is short, or the tenant could go dark.

In practice, an acquisitions team compares the quoted cap rate against the specific risk profile of the deal, not a benchmark. A new 20-year absolute net lease to a national investment-grade retailer prices very differently from a 5-year renewal option backed by a small franchisee, even in the same corridor. The lease abstract is what lets you defend a cap rate, because it surfaces the term, escalations, and guaranty that justify the price. Our NNN lease abstraction workflow pulls exactly those fields.

What is the difference between an absolute NNN lease and a single tenant net lease?

An absolute NNN lease is one variety of single tenant net lease, not a separate thing. "Single tenant net lease" describes the structure (one tenant, net terms). "Absolute NNN" describes how far the net pass-through goes: in an absolute net or bondable lease the tenant is responsible for everything, including roof, structure, and capital repairs, leaving the landlord with a truly passive check.

Most STNL deals sit on a spectrum. A plain triple net lease usually carves out the roof and structure so the landlord keeps those obligations, while an absolute net lease removes even those carve-outs. That single distinction changes your reserve assumptions and your cap rate. Our guide to what a triple net lease shifts to the tenant covers where these carve-outs typically sit.

Are single tenant net lease properties a good investment?

Single tenant net lease properties can be a good investment for buyers who want passive, predictable income and are comfortable concentrating risk in one tenant. The appeal is a long lease, scheduled rent growth, minimal landlord obligations under net terms, and a clean structure that fits a 1031 exchange well, since replacement property has to be identified and closed on a tight clock and STNL deals are simple to underwrite.

The trade-off is diversification. You are effectively buying a bond backed by one company's ability to pay rent, wrapped around real estate. For 1031 buyers rolling gains out of a management-heavy asset, that simplicity is the point. For investors who cannot absorb a total income interruption, the concentration is a real problem, so it comes down to matching the tenant's credit and lease term to your own hold horizon.

What are the risks of a single tenant net lease?

The main risks are binary vacancy, credit risk, go-dark risk, and residual value risk. Because one tenant carries the entire property, a default or a decision not to renew takes income to zero overnight, and re-tenanting a purpose-built box (a former bank branch or a drive-through) can be slow and expensive. Credit risk means a franchisee guaranty is not the same protection as a corporate one.

Go-dark risk is specific to STNL: a tenant can keep paying "dark rent" while closing the store, which hurts the site and your eventual resale even though checks still clear. Residual value risk is what the asset is worth when the lease burns down to a few years left, since a short remaining term compresses value quickly. Rent bumps that lag inflation quietly erode real return over a long hold. None of these show up on a cover page, which is why the abstract matters.

What should you abstract from a single tenant net lease before you buy?

Before you buy, abstract the commencement and expiration dates, the current and scheduled base rent, every escalation and how it is calculated, all renewal and termination options, and the exact tenant of record and guaranty (corporate versus franchisee). Then capture the net structure: who pays taxes, insurance, and maintenance, and whether roof, structure, and HVAC capital are the tenant's or the landlord's.

You also need the operating clauses that move value: any go-dark or continuous-operations provision, use and exclusive clauses, assignment and subletting rights, and any purchase option or right of first refusal. On acquisition, line up the estoppel certificate and the SNDA so the tenant confirms the terms and your lender's position is documented. A standardized lease abstract template keeps these fields consistent deal to deal, and most buyers pull the offering memorandum's PDF rent schedule into a spreadsheet before they drop the numbers into a model. This is due-diligence work that asset managers and lease abstraction for lenders both depend on, since the loan sizing and the ongoing hold both rest on the same lease facts.

The table is directional. Any given lease can allocate obligations differently, so the document controls, not the label on the flyer.

Turn the lease into fields you can underwrite

STNL is only simple once you have read the lease. Our lease abstraction software reads a single tenant net lease and returns the dates, rent schedule, escalations, options, guaranty, and net-expense responsibilities as structured data you can drop straight into a model or a loan file. If you are buying a group of net-leased assets or a 1031 replacement pool, you can abstract a portfolio in one batch and compare cap rate drivers side by side. Start with the NNN lease abstraction workflow and let the abstract, not the cover page, set your price.
