Florida Net Lease Broker: NNN, STNL and Ground Lease Advisory

Home › Investment Sales › Net Lease

Last updated: August 2026

A single-tenant net lease property is a building leased in its entirety to one tenant under a lease that shifts property expenses from the landlord to that tenant, so the owner collects rent and, depending on the structure, does little or nothing else. The trade press abbreviates it STNL. Ironmark Capital Advisory is a Florida industrial and net-lease brokerage, and most owners who call this desk are doing something they have never done before: selling the building their operating business has occupied for twenty or thirty years and moving that equity into income they no longer have to run. This page is written for that reader. It covers the lease structures and who pays for what, what a credit tenant and a corporate guarantee actually mean, how term and escalations drive value, what categories trade, where cap rates sat in the second quarter of 2026 by credit tier, and the risks — stated plainly, because a retirement concentrated in one building deserves the downside in writing.

What is a single-tenant net lease (STNL) property?

A single-tenant net lease property is a commercial building occupied by one tenant on a lease that assigns some or all of the property-level operating costs — property taxes, building insurance, maintenance, and in the strongest structures the roof and the structure itself — to that tenant rather than to the owner. The owner's return is the contractual rent stream, and the owner's job is to underwrite the entity that promised to pay it. Common Florida examples are freestanding drugstores, quick-service restaurants, auto-parts stores, dollar stores, urgent-care and dental clinics, convenience stores with fuel, bank branches, car washes, and single-tenant industrial and distribution buildings.

For an owner-user, the shift is larger than it looks. In the building you occupy today, you are the tenant, the landlord, the facilities manager and the credit. In a net lease you are only one of those things: the owner of a promise. That is why the analysis on this page spends more time on the entity signing the lease than on the four walls. As Ironmark's own Florida Net-Lease Brief, 2Q 2026 puts it, the tenant, the guarantee and the remaining term drive the cap rate far more than the building does.

NNN vs absolute net vs double net vs ground lease: who pays for what?

“NNN” is not one thing. It is a rung on a ladder, and each rung moves a specific, nameable obligation across the table. The headline on a listing tells you the intent of the deal; the allocation of the roof lives in the lease, in a numbered section, and that section is the one to read first. The table below runs the ladder in the order landlord responsibility falls away.

The double net rung is where first-time buyers get caught. An NN listing and an NNN listing can carry nearly the same headline cap rate while allocating a roof replacement to opposite sides of the table. When comparing two offerings, the useful question is never “is it net lease.” It is which specific obligations this lease puts on the owner, in which section, and what those obligations cost over the remaining term.

The ground lease deserves its own line because it behaves differently in three ways. The landlord's obligations are close to nil. The position sits senior to the building, so improvements typically revert on a tenant default. And it prices tighter than fee-simple product: The Boulder Group reported premium ground-lease cap rates on the McDonald's and Chick-fil-A type of product at 4.45% in Q2 2026, roughly 237 basis points inside the all-sector single-tenant average (The Boulder Group, Net Lease Research Report, Q2 2026, published 7 July 2026). The tax consequence is the one owner-users miss, and it is covered under the tax section below.

What does a “credit tenant” and a “corporate guarantee” actually mean?

A credit tenant is a tenant whose obligation to pay rent is backed by an entity with a published credit rating from a nationally recognized statistical rating organization — S&P Global Ratings, Moody's or Fitch. The market divides that scale at one point: BBB− and above at S&P and Fitch, or Baa3 and above at Moody's, is investment grade; anything below is speculative grade. Those thresholds are published by the agencies themselves in their rating-definition documents, and they are the line that most net-lease pricing is organized around.

Two qualifications belong in the same breath, because leaving either out is how buyers get hurt. First, a rating attaches to a rated entity — not to a property and not to a brand. “Investment-grade tenant” in a listing headline is a marketing phrase until you have identified the legal entity on the signature line and confirmed that entity is the one carrying the rating. Second, a rating is a point-in-time opinion and it moves. Ratings are affirmed, upgraded and downgraded on the agency's schedule, not yours, and a downgrade can arrive without a single thing changing about the building you own.

The three guarantees, and why they are not interchangeable

The price of that distinction is published, and it is the most efficient argument on this page. The Boulder Group reports corporate-guaranteed and franchisee-guaranteed quick-service restaurants as separate categories. In Q2 2026, corporate-guaranteed QSR asking cap rates averaged 5.85% and franchisee-guaranteed QSR averaged 6.85% (The Boulder Group, Net Lease Research Report, Q2 2026, 7 July 2026). That is a 100-basis-point spread on the same brand, the same building type and the same use — a legal distinction converted into a price by a named, dated, published source. The sign out front is identical either way.

Three further clauses decide whether the credit you underwrote is the credit you keep. Guarantees can be capped at a stated dollar or month limit, rolling so that they burn off over time, or conditional; the word “guaranteed” without the cap is not a fact about the deal. Assignment provisions determine whether the lease can be transferred to a weaker obligor without your consent. Go-dark provisions determine whether the tenant may close the store and keep paying, which is a different asset from an operating one. None of this makes franchisee product bad. A strong operator with real unit-level economics and a tight guarantee can be a sound investment. The point is that it has to be priced as franchisee product, and Ironmark's 2Q 2026 brief names the local failure mode precisely: paying a credit cap rate for non-credit risk.

How do lease term, escalations and renewal options change the value?

Remaining term is the second price driver after credit, and it is the least intuitive one for an owner-user, because it behaves nothing like the building being sold. Value tracks remaining term, not original term. A fifteen-year lease with four years left is a four-year asset, and it prices like one.

Remaining term compounds through three channels. It sets how long the income is contractual. It sets whether the asset is financeable and on what terms, because lenders size debt against the lease and loans maturing past lease expiry are penalized. And it sets how large the buyer pool will be at your exit, because the next buyer is looking at an even shorter clock than you are. The Boulder Group's Q2 2026 commentary is consistent with this: assets pairing long remaining term with investment-grade credit attract the broadest buyer pools, while shorter-term and non-rated assets face wider bid-ask spreads and more selective engagement.

Escalations come in three shapes: fixed bumps at a stated percentage annually or in steps every five years, CPI-linked increases, or flat rent through the primary term with all the growth pushed into the option periods. That third shape deserves a plain sentence: a flat primary term is a declining rent in real terms for as long as the tenant holds it.

Renewal options belong to the tenant, not to the landlord. This asymmetry is worth stating outright because it is routinely sold as extra term. If market rent has run above the option rate, the tenant exercises and the owner is capped at the option rent. If market rent has fallen below the option rate, the tenant walks and the owner is re-tenanting. Options are priced into the asset in the tenant's favor. Contractual term is a fact; renewal is behavior — driven by unit-level performance, the tenant's real estate strategy, the cost of relocating that particular use, and whether the location still fits the network. A branch-rationalizing bank or a shrink-to-core pharmacy will hand back a perfectly good building.

Ironmark's own screening preference for buyers placing exchange equity is a corporate guarantee, ten or more years of remaining term, an absolute-NNN structure and scheduled escalations. That is a preference, not a rule, and every one of those four inputs is negotiable against price.

What kinds of net-lease properties actually trade?

The single-tenant tape is dominated by a handful of categories, and the credit story inside each one is different. Every figure below is The Boulder Group's Q2 2026 asking cap rate, from the same report on the same date, so the categories are internally comparable.

• Auto parts — 6.45%, unchanged in Q2 2026. The tightest of Boulder's published retail categories, driven by corporate guarantees on long terms from a small set of well-rated operators.
• Quick-service restaurants — 5.85% corporate, 6.85% franchisee. Two entirely different assets under one heading. Franchisee-level distress across several major burger and chicken systems has been persistent rather than acute since 2023, with food-cost inflation, higher borrowing costs and deferred remodel capital the commonly cited drivers (Nixon Peabody client alert on navigating QSR franchisee bankruptcies, 12 August 2026).
• Dollar stores — 7.49%, 89 basis points outside the retail average. A useful teaching case: the major operators are rated, yet the category prices wide, because supply weight, building generic-ness and vintage are doing the work. Investment grade is necessary, not sufficient. The real estate still has to clear.
• Drugstores and pharmacy — 7.85%, the widest of Boulder's published retail categories and 125 basis points outside the retail average. This is the sector carrying the most visible credit risk, and the reasons are on the public record — see the risk section below.
• Convenience and fuel. Transacts around the retail average, with dispersion driven by operator credit and fuel-brand strength. Environmental diligence is a real, category-specific cost item here that does not exist in the others.
• Medical, dental and dialysis. The cleanest illustration of the credit thesis in the asset class: two operators running near-identical clinical businesses out of near-identical buildings can sit on opposite sides of the investment-grade line. Site specificity and payor concentration are the additional risks.
• Single-tenant industrial — 7.25%, up 10 basis points, the widest quarterly move of Boulder's three sectors. Industrial and logistics accounted for 63% of Q2 2026 net-lease investment volume at $8.1 billion, up 28% year over year, with single-asset sales up 37% (CBRE, U.S. Net Lease Investment Figures, Q2 2026, 13 August 2026).

Industrial is the category where Ironmark's Florida leasing and investment sales work is most directly useful to a net-lease buyer, and the reason is residual value rather than yield. A modern logistics or flex building serves a broad pool of alternative occupiers. A purpose-built single-tenant retail box, by design, does not. That is a re-tenanting argument, and it is one this firm can make from Florida industrial deal experience rather than from a report. If the replacement asset is going to be industrial, the same underwriting applies to industrial outdoor storage and to buildings in the metros covered on the Tampa, Orlando, Jacksonville and Miami-Dade pages.

Where do net-lease cap rates sit by credit tier and term?

Read top to bottom, the table below is the thesis of this page. The range from 4.45% to 7.90% is almost entirely a function of guarantee quality, lease structure and remaining term — not of construction quality or square footage. All figures are asking cap rates from a single source on a single date, so the comparison is internally consistent.

Why three reputable firms published three different Q2 2026 numbers

Three research houses published a single-tenant net-lease cap rate for the second quarter of 2026 and they do not match. That is not an error in any of them, and a buyer who understands why is better armed than a buyer quoting one figure.

Note that The Boulder Group shows industrial wider than retail while CBRE shows industrial tighter than retail. Both are correct inside their own definitions. Asking cap rates are a function of what sellers list; closed cap rates are a function of what buyers actually pay. In a two-tier market those diverge, because the widest-cap product lists and sits while the tightest product trades quickly and quietly. Anyone quoting a single national cap rate without saying which series it came from is quoting a number they have not checked.

The supply picture, and why the listing count is misleading

There were roughly 5,800 single-tenant properties on the market in Q2 2026, up 12.5% quarter over quarter, with retail supply up 16.2% — and at the same time, investment-grade retail assets with long remaining term were under 10% of available retail inventory (The Boulder Group, Q2 2026). That pair of facts is the whole market in one sentence: there are more listings than there were, and fewer of the ones a conservative buyer wants. Bid-ask spreads sat at 22 basis points in both retail and industrial. On the capital side, U.S. net-lease investment volume reached $12.8 billion in Q2 2026, up 13% year over year and about 10% of all U.S. commercial real estate investment, on a trailing-year figure of $57 billion, up 14%. Private investors bought $7.3 billion of that, up 16% year over year, against $2.3 billion for institutions and equity funds and $1.0 billion for REITs, which fell 9%. The cap-rate spread to the 10-year Treasury was 241 basis points, 10 basis points narrower than the prior quarter, against an average 10-year yield of 4.5% (CBRE, 13 August 2026). The private buyer — often an all-cash exchange buyer — is the dominant force in this market, which is exactly who this page is written for.

For longer context: Northmarq reports single-tenant retail cap rates roughly 125 basis points above their fourth-quarter 2022 low of 5.60% (Northmarq, MarketSnapshot: Single-Tenant Retail, Q2 2026, 27 July 2026). An owner who last transacted in 2021 is pricing against a market that no longer exists.

Is there a Florida-only net-lease cap rate?

No published Florida-only single-tenant net-lease cap-rate series exists on a cadence comparable to the national data, and Ironmark does not publish one. That is stated in the data note of the Florida Net-Lease Brief, 2Q 2026, and it is worth repeating here because Florida cap-rate ranges circulate freely online with no stated methodology, no sample and no date on the underlying data — and several sites recycle the same numbers. The nearest sourced regional datapoint is Northmarq's: the Southeast was the largest region for single-tenant retail sales volume in Q2 2026 at $716.4 million, or 22.3% of the $3.2 billion national total, with regional cap rates ranging from 6.40% in the West to 7.58% in the Midwest (Northmarq, 27 July 2026). Ironmark's own read, stated as a read and not as a series, is that prime Florida net lease — a corporate-guaranteed tenant on a long absolute-NNN lease in a growth corridor — typically prices at or slightly inside the national sector medians, while secondary locations and weaker credit widen out in line with or beyond the national ranges. For a specific asset, the honest answer is a live comparable set in that submarket, which is what a valuation or a buyer-representation engagement produces.

What are the real risks of owning a single-tenant net lease?

Every competitor page in this category sells the upside. An owner-user converting a career's worth of equity into one asset is entitled to the downside first, and in specific terms.

1. Binary income risk. One tenant is 100% of the income. There is no diversification inside the asset, and occupancy is either 100% or 0%. A multi-tenant building that loses one of six tenants has a bad quarter. A single-tenant building that loses its tenant has no income at all — while still owing taxes, insurance and debt service.

2. Rollover at lease end. The lease ends on a known date; what happens next is not known. Renewal is the tenant's option, not the landlord's right. If the tenant leaves, the owner funds carry costs, leasing commissions, tenant improvements and a re-tenanting period usually measured in quarters, out of a rent roll that has just gone to zero.

3. Residual value — the dirt still matters. Credit is the first source of repayment; the real estate is the second. When the credit fails, what remains is a parcel with a location, an access pattern, a visibility profile, a size, a zoning designation, a parking count and a building configuration. Purpose-built boxes with unusual footprints re-tenant badly. Well-located, flexible, correctly zoned dirt re-tenants. A buyer paying a tight cap rate for strong credit on a building with no alternative use has bought a bond with a demolition cost attached.

4. Tenant bankruptcy, and what a filing actually does to a landlord. The mechanics are counter-intuitive and worth stating precisely. In a Chapter 11, the debtor may assume or reject the lease under 11 U.S.C. §365. A rejection terminates the landlord's stream and converts the landlord into an unsecured creditor for damages — and 11 U.S.C. §502(b)(6) caps a landlord's damage claim, so recovery is typically a fraction of the remaining contractual rent. That is a description of the statute, not legal advice; anything beyond the general description belongs with your attorney.

5. The credit can deteriorate without the building changing. The pharmacy sector is the live illustration. Rite Aid filed for Chapter 11 a second time in May 2025, roughly eight months after emerging from its first filing, and closed its remaining stores in October 2025, ending the chain (reported by CNN, NBC News and CBS News, October 2025). Walgreens was taken private by Sycamore Partners in a transaction that closed 28 August 2025, and drugstore cap rates that sat in the mid-6s in 2024 moved into the 7s and higher during 2025, with spreads widening by market, term and credit (Northmarq, “Walgreens after Sycamore: what shrink-to-core means for retail real estate,” 29 September 2025). None of that required a single change to the buildings involved. And a dark store still paying rent is not the same asset as an occupied one: the rent may run to the end of the term, but a closed store erodes residual value and re-leasing prospects, while returning boxes add competition in the same corridors.

6. Interest rates and an unknowable exit. Net-lease pricing is a spread business. Cap rates move against the long end of the curve, and the exit cap rate is not knowable at purchase. The Q2 2026 spread to the 10-year Treasury sat at 241 basis points against an average 10-year yield of 4.5% (CBRE, 13 August 2026) — thinner than the long-run norm, which constrains how far quality cap rates can compress from here.

7. Liquidity depends on the credit, not on the price. The buyer pool for a corporate-guaranteed, long-term, absolute-NNN asset is deep and largely all-cash exchange money. The pool for a five-year franchisee deal in a secondary market is a fraction of that size, and it thins further when rates are volatile.

8. For the 1031 buyer, the clock is itself a risk. A buyer inside a 45-day identification window is a buyer with reduced negotiating leverage and a structural incentive to accept a worse asset than they would otherwise accept. That is the single most important reason to begin the replacement search before the relinquished property closes, and it is covered in full on the 1031 exchange advisory page.

How net lease fits the 1031 and cost-segregation math

Net lease is the destination asset most Florida owner-users have in mind when they start a 1031 exchange, so the tax framework matters — as general information, with the conditions attached.

Section 1031. Since the Tax Cuts and Jobs Act, §1031 applies to exchanges of real property only; personal property and intangibles no longer qualify, and both the relinquished and the replacement property must be held for productive use in a trade or business or for investment (26 U.S.C. §1031; Pub. L. 115-97 §13303; IRS Instructions for Form 8824). Replacement property must be identified in writing within 45 days of the transfer of the relinquished property, and received by the earlier of 180 days after that transfer or the due date, including extensions, of the taxpayer's return for the year of the transfer. The 45 days run inside the 180, not in addition to them, and the regulation provides no weekend, holiday, or good-cause extension. A late-in-the-year closing can therefore compress the exchange period well below 180 days unless the return is extended. Boot, debt replacement, related-party rules and sale-leaseback interactions are all real conditions with real consequences; they exist, and they belong to your CPA, your attorney and your qualified intermediary.

Bonus depreciation and cost segregation. The One Big Beautiful Bill Act, signed 4 July 2025, permanently restored 100% first-year bonus depreciation for qualifying property acquired after 19 January 2025 (Pub. L. 119-21 §70301, enacted 4 July 2025; interim guidance at IRS Notice 2026-11, announced in IR-2026-06 on 14 January 2026). The conditions matter as much as the headline: property acquired under a binding contract on or before 19 January 2025 remains on the pre-OBBBA phase-down, a taxpayer may elect 40% — or 60% for certain longer-production-period property and certain aircraft — instead of 100%, and “acquired” and “placed in service” are two different tests applied on two different dates. Qualifying property is generally tangible MACRS property with a recovery period of 20 years or less (26 U.S.C. §168(k)(2)(A)(i)(I)); qualified improvement property qualifies because it carries a 15-year recovery period, not because §168(k) names it. The mechanism, stated neutrally: a cost-segregation study reclassifies components of a building's basis out of the 39-year line into shorter-lived categories — 5-year personal property, 7-year equipment and 15-year land improvements such as paving, parking, landscaping and site lighting — which, having class lives of 20 years or less, can be eligible for bonus treatment. Passive activity loss rules under §469, the at-risk rules and recapture on disposition all condition the outcome. The full treatment lives on the cost segregation page.

Why the structure choice interacts with the tax question. Cost segregation works on depreciable improvements. A ground lease is a land position with no building in the owner's basis, and leasehold and zero-cash-flow positions have the same problem in different forms. A buyer choosing a structure specifically to pair an acquisition with a cost-segregation study is therefore choosing among fee-simple assets. That is a structural observation about what creates depreciable basis, not a recommendation about what to buy.

Two Florida facts worth having straight. Florida imposes no state income tax on natural persons: Article VII, §5 of the Florida Constitution caps any such tax at the amount creditable against a similar federal tax, and because no such federal credit exists the practical ceiling is zero, with amendment requiring a 60% supermajority of voters. That is the personal income tax specifically — it does not describe every Florida tax a business entity may owe, and how you take title changes the question. Separately, Florida documentary stamp tax on deeds is 70¢ per $100, or portion thereof, of total consideration in every county except Miami-Dade; Miami-Dade is 60¢ per $100 plus a surtax of 45¢ per $100, and that surtax does not apply to a document transferring only a single-family dwelling (Florida Department of Revenue). Reading those two rules together with §1031: a 1031 exchange defers federal capital gains tax; it does not avoid Florida documentary stamp tax, which is due at closing on the transfer.

How Ironmark works on net lease in Florida

Ironmark Capital Advisory is a Florida-only industrial and net-lease brokerage, and net-lease work here is advisory rather than inventory. The national portals list more properties than any boutique ever will; what they cannot do is read the guarantee, price the difference, and tell an owner when the answer is no.

• Buyer representation — sourcing and underwriting replacement assets on one side of the deal, including off-market product, with the guarantee, the remaining term, the escalation schedule and the residual real estate underwritten separately
• 1031 exchange advisory — running the replacement search against the 45- and 180-day calendar, ideally beginning before the relinquished property closes
• Investment sales — disposition of single-tenant and industrial assets to the private, institutional and exchange buyer pools active in Florida
• Valuation — a defensible opinion of value on the building you own today, which is where most owner-user exits actually start
• Industrial outdoor storage and single-tenant industrial — the categories where Florida leasing experience turns into a real re-tenanting judgment
• Published research — including the quarterly Florida Net-Lease Brief, with sources named and methodology stated

Ironmark is an SIOR-designated advisory, works one side of a transaction rather than both, and names its sources. Where a number is not published, this firm says so rather than inventing a range.
