A triple net lease, or NNN, property makes the tenant responsible for property taxes, insurance, and maintenance in addition to rent, leaving the landlord with a largely passive income stream and minimal operating involvement. As 1031 replacement property, NNN assets appeal to exchangers moving out of management-intensive property — an apartment complex or a portfolio of rentals — who want the deferral without trading one set of landlord duties for another.
The trade is concentration: unlike a multifamily property with dozens of tenants, most NNN assets have a single tenant, so your income depends entirely on that one tenant's ability and willingness to keep paying rent for the length of the lease.
The lease, not the building, is the asset you are actually buying. Pull the full executed lease and every amendment, not a summary, and check the remaining primary term, renewal options and their rent terms, any early termination rights, and exactly which expenses are truly passed through versus retained by the landlord — some leases labeled "triple net" still leave roof and structure repairs with the owner.
Confirm rent escalations are contractual, not projected. A lease with flat rent for the next fifteen years carries different economics than one with 2 percent annual bumps, even at the same starting cap rate.
A publicly traded, investment-grade tenant carries meaningfully less default risk than a regional or private operator, and that difference shows up in the cap rate you should expect to pay — a lower cap rate for stronger credit is not overpaying, it is pricing the risk correctly. Pull the tenant's public financials if available, or request financial statements and store-level sales data if the tenant is private and the lease permits disclosure.
Look past the corporate name to the actual lease guarantor. A location operated by a franchisee under a weaker guarantee than the parent brand's balance sheet carries different risk than a corporate-guaranteed store, even with an identical storefront.
Model your return through the end of the primary lease term, not just the cap rate at purchase, and ask specifically what the property is worth if the tenant does not renew. A single-tenant building built to one retailer's specifications can require significant capital to re-lease to a different use, and that re-leasing cost and downtime should factor into your purchase price, not come as a surprise years into ownership.
Renewal options set at fixed rents below market, common in older leases, can also work against you as a buyer if the tenant exercises a below-market renewal instead of vacating, locking in income growth below what the location could otherwise command.
A strong tenant on a weak site is still a weak long-term investment, because if that tenant ever leaves, the real estate has to stand on its own. Evaluate traffic counts, visibility, competing supply, and the surrounding trade area's trajectory the way you would for any commercial site, rather than relying entirely on the tenant's credit to carry the underwriting.
Ask a local commercial broker, not just the listing broker, for an honest read on the site's re-leasing prospects if the current tenant vacated tomorrow — that answer tells you what you actually own beneath the lease.
NNN properties trade actively and close relatively quickly compared to more complex asset types, which makes them a common choice under deadline pressure, but availability of well-underwritten, investment-grade NNN deals is not unlimited, and thin markets can leave you choosing between a rushed purchase and a lower-quality tenant. Start your NNN search as early in the exchange as possible rather than treating it as a fallback once other options fail.
If a single NNN property cannot absorb your full proceeds, pairing it with a second property or a DST allocation for the remainder is a common way to hit your reinvestment target without forcing an oversized single-tenant purchase.
