A single tenant net lease, STNL for short, is about as simple as commercial real estate gets on the surface: one building, one tenant, one lease, rent arrives every month with little for the landlord to do beyond depositing the check. That simplicity is exactly why the asset class attracts investors who want real estate income without the phone calls that come with a multi-tenant strip center or an apartment building, a bank drive-thru on Veterans, a pharmacy in Metairie, a fast food pad on Airline Highway.
The Appeal Is Real, but It's Narrow
Because a well-underwritten STNL deal produces bond-like income with minimal landlord responsibility, it's often marketed as passive real estate ownership, and for the length of a strong tenant's lease term, it largely is. The narrowness comes at the end of that term, or if the tenant closes early despite the lease, since a single tenant property with a dark building and no income has nothing else to fall back on the way a multi-tenant asset can lean on its other leases while one space sits vacant.
Reading the Credit Behind the Lease
The tenant's corporate credit matters more in an STNL deal than almost any other underwriting factor, since the rent stream is only as reliable as the entity signing the lease. A corporate-guaranteed lease from an investment-grade national tenant carries a very different risk profile than a franchisee-guaranteed lease from a single-unit operator, even when the building, rent, and remaining term all look identical on the flyer. Buyers should ask specifically whether the guarantee sits with the parent company or a franchisee entity, since that distinction rarely shows up clearly in a broker's offering memorandum.
What Happens at Lease Expiration
Re-tenanting a single-purpose building, a drive-thru bank branch or a fast-food pad built to one chain's exact specifications, is rarely as simple as putting up a leasing sign. The building itself may need to be reconfigured or even demolished to attract a new tenant, and that redevelopment cost belongs in the underwriting from day one rather than treated as a problem for whoever owns the property when the lease actually expires. A shorter remaining lease term, all else equal, should command a real discount to reflect that looming re-tenanting risk.
A ten-year lease with two years left trades on a fundamentally different basis than the same lease with eight years remaining, even at an identical current rent, because the buyer is really pricing in the cost and vacancy risk of that re-tenanting event much sooner. Buyers sometimes overlook this and price purely off the in-place cap rate without discounting for how close the property actually sits to its next leasing event.
STNL as 1031 Replacement Property
Single tenant net lease property held for investment is one of the most commonly used replacement property types in a 1031 exchange, largely because it's widely available nationally and closes on a predictable timeline that fits the 45-day identification window better than a more complex asset type might. Investors exchanging out of active, management-intensive New Orleans-area property, an apartment building with turnover and repair calls, or a multi-tenant retail strip with several leases to track, often move into STNL specifically for the reduced landlord workload, and a Delaware Statutory Trust holding STNL assets is a further passive option for investors who want that income stream without holding a single deed directly.
Common 1031 Exchange Questions
Does single tenant net lease property qualify for a 1031 exchange?
Yes, STNL property held for investment or business use qualifies as like-kind replacement property, and it's one of the most commonly used property types in 1031 exchanges due to its national availability and closing predictability.
What's the biggest risk in owning a single tenant net lease property?
Concentration risk. All of the property's income depends on one tenant, so if that tenant vacates or defaults, the property produces no income at all until it's re-leased or redeveloped.
Why does it matter whether an STNL lease has a corporate or franchisee guarantee?
A corporate guarantee from an investment-grade parent company is generally stronger than a franchisee guarantee from a single-unit operator, even when the lease terms and rent look identical, because the entity actually standing behind the rent differs.
What happens if an STNL tenant's lease expires and doesn't renew?
The building may need reconfiguration or demolition to attract a new tenant, since many single-tenant buildings are built to one chain's specific layout, and that re-tenanting cost should be underwritten from the start rather than discovered at lease expiration.
Can a Delaware Statutory Trust hold single tenant net lease property?
Yes, many DST sponsors offer STNL portfolios as 1031-eligible replacement property, giving investors passive exposure to this asset class without holding title to an individual building directly.
