The Question Every NNN Investor Should Ask Before Buying
Most investors who buy NNN properties focus heavily on the day-1 cap rate, the tenant's credit rating, and the income stream during the lease term. Far fewer spend equal time thinking about what happens at lease expiration — the moment when the "guaranteed" income either continues or stops.
Understanding lease expiration scenarios — and how to underwrite for them — is what separates sophisticated NNN investors from those who get surprised by an avoidable outcome.
Scenario 1: The Tenant Renews (Most Common)
Most NNN leases include multiple renewal options — typically three to five 5-year periods. If the tenant's location is performing well (strong sales volume, profitable unit), they will almost always exercise their renewal option and continue paying rent, often with a rental bump built into the renewal terms.
This is the most common outcome for well-located NNN properties. A McDonald's doing $3M+ in annual sales at a high-traffic intersection has no reason to abandon that location when their lease expires — they'll renew, possibly renegotiate to update the rent, and continue for another 5–10 years.
How to underwrite for this: During due diligence, review unit-level sales data if available, traffic counts, and overall location quality. A tenant doing strong sales at your location is a tenant who will renew.
Scenario 2: The Tenant Vacates ("Goes Dark")
If the tenant decides not to renew — either because their lease doesn't obligate them to or because the location is underperforming — the property "goes dark." This is the scenario NNN investors fear most, and for good reason: a vacant single-tenant building is significantly harder to lease or sell than the same building with a tenant in it.
However, "goes dark" risk is manageable with proper upfront underwriting. Key factors that reduce dark risk:
- Location quality: A high-traffic corner property with strong demographics will attract a replacement tenant. A rural location with limited traffic may not.
- Building versatility: A standard 9,000 sq ft dollar store building can be re-tenanted by dozens of different retailers. A highly customized drive-thru configuration limits replacement options.
- Remaining lease term at purchase: Never buy a NNN property with fewer than 7–8 years of primary term remaining without fully underwriting the re-tenanting scenario.
Scenario 3: Lease Renegotiation
In some cases — particularly when market rents have shifted significantly from the lease rate — both parties agree to renegotiate before the formal expiration. This can work in the investor's favor (if market rents have increased) or require a rental concession (if the tenant has leverage and market rents have declined).
Having an attorney review and negotiate any lease renegotiation is essential. Terms that seem reasonable on the surface — extended term in exchange for temporary rent reduction, for example — can have long-term value implications that require careful legal analysis.
Scenario 4: Selling Before Lease Expiration
Many sophisticated NNN investors don't hold to lease expiration at all. They sell the property while significant lease term remains — typically with 10+ years left on the lease — when demand is highest and cap rates are tightest. This strategy:
- Captures maximum appreciation from the remaining lease term premium
- Eliminates rollover risk entirely
- Allows deployment of proceeds (via 1031 exchange) into a fresh long-term lease
- Resets the depreciation clock in the new property
This is the "NNN arbitrage" strategy: buy new construction with a 15-year lease, hold 5–7 years while the lease is still long and the property commands strong cap rate compression pricing, then sell at a premium and 1031 into another fresh lease.
How to Plan for Lease Expiration from Day One
The best time to think about lease expiration is before you buy. When evaluating any NNN property, ask these questions:
- How many years remain on the primary term?
- How many renewal options remain, and at what rent?
- What is the tenant's sales volume at this location?
- What is the location quality — would another tenant want this space?
- What is my exit strategy — sell before expiration, hold through renewal, or plan for re-tenanting?
An experienced NNN broker and attorney will model all three scenarios during due diligence so you enter the investment with clear expectations about each possible outcome.
The Legal Side: What Your Lease Actually Says
Many investors assume their lease says one thing when it actually says another. Common misunderstandings:
- Renewal options are tenant's right, not obligation: The tenant can choose NOT to exercise a renewal option. You cannot force them to renew.
- Holdover provisions: If a tenant stays past lease expiration without formally renewing, they become a month-to-month tenant — giving them (and you) significantly less certainty.
- Early termination options: Some leases include co-tenancy clauses or kick-out options that allow tenants to exit early under certain conditions. These must be identified in due diligence.
