Current marker: In 2026, the NNN cap rate question is no longer simply whether the market average is 6.80%. The better question is what kind of tenant credit, lease duration, lease obligor, and residual real estate risk are hidden inside that average.
A 1031 buyer looking at single-tenant net lease properties in 2026 can easily get pulled toward the highest quoted cap rate on the shortlist. That is understandable. If two properties both have recognizable national tenants and one shows a materially higher yield, the higher cap rate looks like the obvious answer.
That is also where many NNN buyers make the first underwriting mistake.
Cap rates are not a scoreboard. They are a pricing signal. A lower cap rate may reflect stronger tenant credit, longer remaining lease term, better site quality, a cleaner lease structure, or a deeper exit buyer pool. A higher cap rate may reflect real compensation for real risk, or it may be the market warning that the asset has weaker credit support, shorter lease duration, rent that is too high for the site, poor residual value, or a thin resale market.
The job is not to buy the lowest cap rate. The job is to understand what the cap rate is paying you for.
The 2026 NNN market average is useful, but incomplete
The Boulder Group reported that overall single-tenant net lease asking cap rates decreased one basis point to 6.80% in Q1 2026. Retail cap rates held at 6.55%, office compressed to 7.90%, and industrial declined to 7.15%. The same report showed total single-tenant property supply falling 9.8% from Q4 2025 to Q1 2026, with retail supply down 11.1%.
That headline tells us the market is not frozen. It also tells us the market is not uniform.
Boulder described a continued bifurcation: premium credit assets with long remaining lease terms attracted the broadest buyer pools, while shorter-term and non-rated assets faced wider bid-ask spreads and more selective buyer participation. That distinction matters more than the average itself.
Northmarq’s Q1 2026 single-tenant retail reporting also points in the same direction: private buyers remain a dominant force in the single-tenant retail market, which matters because 1031 exchange investors and private capital often compete for the same clean, financeable replacement assets.
So the 6.80% market average is a starting point. It is not an underwriting answer.
Credit quality changes the buyer pool
Tenant credit quality affects more than the rent check. It affects financing, marketability, resale liquidity, and the number of buyers who can say yes when the property comes back to market.
In public credit markets, rating agencies such as S&P and Fitch use credit ratings to express relative credit risk. For NNN underwriting, the investment-grade threshold is generally BBB- or higher from S&P or Fitch, or Baa3 or higher from Moody’s. That threshold is not a guarantee of rent, value, financing, or suitability. It is a credit screen.
The market typically prices that screen into cap rates.
Long-term leases to high-demand, stronger-credit tenants can trade at materially tighter cap rates than the market average. The Boulder Group’s Q1 2026 tenant profile data, summarized on its research page, showed premium long-term quick-service restaurant and convenience assets such as McDonald’s, Chick-fil-A, and Wawa occupying the tightest portion of the market. By contrast, shorter-term, non-rated, pharmacy, and dollar-store assets can price at much wider yields depending on tenant profile, lease term, rent level, and local real estate quality.
That does not mean every low-cap asset is good or every high-cap asset is bad. It means the cap rate is already telling you how much confidence the market has in that income stream and exit path.
The same brand can carry different risk in different leases
A buyer should not stop at the sign on the building. The brand may be famous, but the lease may be signed by a subsidiary, a local franchisee, a regional operator, or a special-purpose entity.
That distinction can change the credit story completely.
A corporate lease backed by the rated parent company is not the same risk as a lease to a franchisee using the same brand name. A lease with a full parent guarantee is not the same as a lease with a limited guaranty. A lease to a subsidiary may or may not provide direct claim on the credit strength that attracted the buyer in the first place.
This is why the tenant credit screen should always start with the actual lease obligor. Who signs the lease? Who guarantees payment? Is the guaranty full or limited? Is the rated entity directly obligated, or is the buyer relying on brand halo?
If the answer is unclear, the cap rate may not be comparable to other deals using the same tenant name.
Lease duration is part of the credit price
In 2026, buyers are not only pricing tenant credit. They are pricing time.
A 15-year lease to a strong tenant with fixed increases is a different instrument from a five-year lease to the same brand with flat rent and near-term rollover risk. The first asset may attract 1031 buyers, lenders, private capital, and institutional bidders. The second asset may require a buyer who is comfortable underwriting renewal probability, market rent, site reuse, and re-tenanting downtime.
That is why comparing cap rates without comparing lease term is sloppy underwriting.
A lower cap rate on a long-term lease may be rational if the buyer is purchasing longer income visibility and a deeper resale pool. A higher cap rate on a short-term lease may be rational only if the buyer has been paid enough for renewal risk and residual real estate exposure.
Residual real estate value can override tenant credit
Tenant credit matters, but it is not the whole investment.
A NNN buyer owns real estate. If the tenant leaves, rejects a lease, closes a store, or chooses not to renew, the owner is left with a building, a parcel, a local trade area, zoning, access, parking, market rent, and re-tenanting risk.
That is why two properties with similar tenant credit can deserve different cap rates.
A high-credit tenant in a weak location with a highly specialized building can still create exit risk. A lower-rated or non-rated tenant in a dominant location with below-market rent and broad reuse may offer better residual protection than the credit label suggests. The market average does not capture that difference. A disciplined buyer has to.
For a deeper framework on this distinction, see Tenant Credit Ratings vs Real Estate Residual Value.
How credit quality shows up in cap-rate spreads
Cap-rate spreads widen when buyers need compensation for uncertainty. In NNN real estate, that uncertainty can come from several places:
- Non-rated or below-investment-grade tenant credit
- Franchisee or subsidiary lease obligor risk
- Short remaining lease term
- Flat rent or rent above market
- Weak store-level sales or rent coverage
- Specialized buildings with limited reuse
- Tertiary markets with thin buyer demand
- Financing friction or lower lender appetite
That is why a buyer should ask one hard question whenever a deal screens cheap: what risk is the market forcing the seller to price in?
Sometimes the answer is acceptable. A buyer may intentionally purchase a wider-cap asset because the site is strong, the rent is below market, the tenant has strong local unit economics, or the buyer has a clear re-tenanting thesis. That can be real underwriting.
But buying a wider cap rate simply because the tenant is a recognizable name is not underwriting. It is yield chasing.
A practical credit-quality reading of the 2026 market
For private NNN buyers and 1031 replacement-property investors, the 2026 market can be read in four broad bands.
First, premium-credit, long-term leases. These are the assets with the deepest buyer pools. They often include strong corporate credit, long remaining lease term, clean lease structure, and durable site quality. Cap rates may look tight, but the buyer is paying for lower perceived income and exit risk.
Second, investment-grade or near-investment-grade tenants with property-level questions. These deals may have good credit but require careful review of lease term, rent level, store relevance, market rent, and residual value. A famous tenant does not eliminate real estate risk.
Third, franchisee, subsidiary, or non-rated tenants with strong operations. These can be attractive when the operator is well capitalized, the unit economics are strong, the lease is well structured, and the site has credible reuse. They require more work because the buyer cannot outsource the decision to a public credit rating.
Fourth, distressed, short-term, over-rented, or operationally challenged assets. These may show the highest cap rates, but they also require the most conservative underwriting. The buyer should model renewal failure, downtime, tenant improvement cost, leasing commissions, and a lower exit multiple.
The point is not that one band is always better. The point is that each band requires a different buyer, lender, hold period, and exit thesis.
What a 1031 buyer should do before chasing yield
The 45-day identification window can pressure a buyer into simplifying the decision. That is exactly when the credit-quality screen matters most.
Before identifying a NNN property only because it offers a higher cap rate, a buyer should answer these questions:
- Is the lease obligor the rated parent, a subsidiary, a franchisee, or another entity?
- Is there a parent guarantee, and if so, what does it actually cover?
- How many years remain on the lease?
- Are rent increases fixed, CPI-based, flat, or uncertain?
- Does current rent appear sustainable relative to the tenant’s unit economics?
- What happens to the property if the tenant leaves?
- Would another buyer finance this asset easily at resale?
- Is the cap-rate premium large enough to compensate for these risks?
Those questions are more useful than asking whether the cap rate is above or below the market average.

The bottom line
NNN cap rates in 2026 should be read through credit quality, not around it.
The market average of 6.80% gives buyers a benchmark, but it does not explain the asset. The real underwriting work is separating income durability from brand recognition, lease obligor from parent credit, lease term from headline yield, and residual value from tenant reputation.
A higher cap rate is not automatically better. A lower cap rate is not automatically safer. The right cap rate is the one that properly compensates the buyer for tenant credit, lease structure, real estate quality, financing risk, and exit liquidity.
