Borrowing to Buy NNN: A Plain-English Guide to Net Lease Financing and Interest Rates

Net lease financing and interest rates sit at the center of every NNN deal — yet most first-time investors treat them as an afterthought. They find the property, love the tenant, then scramble to figure out how to pay for it. This guide flips that sequence. You will learn exactly how borrowing costs interact with cap rates, what lenders actually look for in a single-tenant deal, which loan structures are available in the 2026 market, and how to stress-test your numbers so that a rate move does not catch you off guard. Understand the financing side first, and buying your first NNN property becomes a much cleaner decision.

What “Net Lease Financing” Actually Means for a First-Time Buyer

Net lease financing refers to the debt you place on a single-tenant NNN property at acquisition — almost always a fixed-rate commercial mortgage secured by the property itself and the long-term lease behind it. Unlike a multifamily or office loan, where the lender underwrites the sponsor’s ability to manage a complex asset, an NNN loan is fundamentally underwritten against the lease and the tenant’s credit. That distinction changes everything about how lenders price and structure the debt.

Investors often use commercial mortgages or leverage 1031 exchange proceeds to finance net lease acquisitions, and lenders favor net lease properties with strong tenants precisely because of their stable, predictable cash flow.
That stability — rent arriving on a fixed schedule with the tenant covering taxes, insurance, and maintenance — makes NNN one of the most lender-friendly property types in commercial real estate.

The key players in the NNN lending market are banks (including regional and community banks), life insurance companies, CMBS conduit lenders, and debt funds. Each has a different appetite for loan size, lease term, and tenant credit. Getting familiar with all four gives you options, and options give you leverage.

How Interest Rates Drive Net Lease Financing Costs Right Now

Before you can evaluate a deal, you need to understand where benchmark rates sit.
The Federal Reserve held interest rates steady at its most recent FOMC meeting, with the federal funds rate unchanged in a 3.50%–3.75% range.
Meanwhile,
the 10-year Treasury has already swung sharply this year, with its current yield over 4%.
As of early May,
the yield on the 10-year Treasury note was seen at approximately 4.43%.

Why does the 10-year Treasury matter so much? Because most fixed-rate commercial mortgages — including those used to finance NNN properties — are priced as a spread above the 10-year yield. A lender might quote you “10-year Treasury plus 175 basis points,” which at a 4.43% Treasury would produce a loan rate of roughly 6.18%.
Commercial mortgage loan spreads averaged 197 basis points in Q4 2025, based on fixed-rate, seven-to-ten-year loans with 55-to-65% loan-to-value ratios.

The Spread Between Your Cap Rate and Your Loan Rate

The most important calculation in any leveraged NNN deal is the “spread” between your going-in cap rate and your all-in borrowing cost. If the cap rate exceeds the loan rate, leverage works in your favor — a condition known as positive leverage.
Single-tenant net lease cap rates decreased by one basis point to 6.80%, while retail cap rates remained unchanged at 6.55% in the first quarter of 2026, according to The Boulder Group.
With loan rates in the 6%–6.5% range for well-qualified buyers on strong tenants, positive leverage is achievable on many deals — though it requires careful lender selection and tenant credit quality.

A CBRE Econometric Advisors review of cap rates since 1995 shows that for every 100-basis-point change in the 10-year Treasury yield, cap rate movements range between 41 basis points for industrial assets to 78 basis points for retail assets.
In plain English: cap rates and interest rates move together over time, but not point-for-point — which is why NNN has historically absorbed rate cycles better than most investors expect.

What Lenders Look for When Financing a Net Lease Property

NNN lenders underwrite a deal differently than you might expect. They are not primarily analyzing the building — they are analyzing the lease and the tenant behind it. Here is a plain-language breakdown of the five factors that drive approval and pricing.

• Tenant credit quality. An investment-grade tenant (S&P BBB- or higher) unlocks better loan terms, higher LTVs, and lower interest rates.
  The net lease market remains bifurcated between investment-grade credit assets with long lease terms, which continue to attract institutional buyers, 1031 exchange capital, and private investors, and shorter-term or non-rated assets, which face wider spreads and more selective buyer engagement.
• Remaining lease term. Most lenders want the lease to extend well beyond the loan maturity. A 10-year mortgage on a property with only 11 years of lease remaining is a harder sell than the same loan on a 20-year lease.
  Lease terms typically range from 10 to 25 years, with options for renewal.
• Loan-to-value ratio.
  Average commercial LTV ratios increased to 60.9% in Q4 2025, up from 60.0% a year ago, reflecting a modestly less conservative approach by lenders.
  For premium investment-grade NNN assets, some lenders will stretch to 65%–70% LTV.
• Debt service coverage ratio (DSCR). Lenders want to see that the property’s net operating income comfortably covers the annual debt service — typically a minimum DSCR of 1.25x.
  Debt service coverage ratios improved to 1.36 in Q4 2025, up from 1.35 the prior quarter.
• Rent escalations. Built-in rent bumps improve the income picture over time. Lenders and buyers both value them — a 10% bump every five years meaningfully changes the long-term return profile of the investment.

Which Loan Structure Is Right for Your First Net Lease Financing?

The most common structures for NNN financing fall into three buckets: bank balance-sheet loans, CMBS conduit loans, and life insurance company loans. Each has trade-offs a first-time buyer needs to understand before signing a term sheet.

Bank Balance-Sheet Loans

Regional and community banks have historically been active NNN lenders, and the good news for 2026 buyers is that they are coming back.
Major U.S. regional banks are projecting renewed growth in commercial real estate lending after years of reducing risk, citing lower interest rates and credit quality stabilizing across properties. Banks including Regions Financial, PNC, M&T Bank, First Horizon, U.S. Bancorp, and KeyCorp told investors during fourth-quarter earnings calls that they expect commercial lending to contribute to their portfolios in 2026.
Bank loans offer flexibility — lenders can customize terms, and relationships matter — but they typically carry shorter amortization periods and sometimes floating rates.

CMBS Conduit Loans

CMBS loans are packaged into mortgage-backed securities and sold to bond investors. They typically offer the highest LTVs and the most competitive fixed rates for well-leased NNN assets, but they come with strict prepayment penalties (defeasance or yield maintenance) and rigid covenants.
CMBS lending volume was approximately six times higher than the prior year in 2025, with market-level issuance reaching $158 billion — its highest annual total since 2007.
That surge in CMBS activity has widened the competitive landscape for borrowers.

Life Company Loans

Life insurance companies are among the most coveted lenders for top-tier NNN assets. They offer long fixed-rate terms — often 10 to 25 years — at competitive spreads, and they are especially attracted to investment-grade tenanted properties with long lease terms. The trade-off is selectivity: life companies set the bar high on property quality, tenant credit, and market location. If your deal qualifies, the loan terms can be exceptional.

Net Lease Financing in the 2026 Lending Environment

The 2026 lending market for NNN properties is meaningfully more accessible than it was during the peak-rate period of 2023–2024.
Commercial real estate lending conditions continued to improve in the fourth quarter of 2025, supported by higher loan origination volumes, increased average loan sizes, relatively stable spreads, and improved loan-to-value ratios.

While alternative lenders are expected to remain active, the reemergence of banks in the debt market is expected in 2026, particularly as the yield curve steepens — and overall, all sources of debt capital are expected to remain active.
For NNN buyers, that means more competition among lenders, which tends to tighten spreads and improve terms.
CBRE expects lending spreads over benchmark rates will remain tight, and while lending standards remain prudent, loan structures and covenants may ease as lenders exhibit increased willingness to provide commercial real estate financing.

Market conditions for retail financing remain solid for most retail assets, driven by relatively stable rates of return, above-average occupancies, and rising net operating income, all of which support healthy refinancing conditions.
For single-tenant retail — the heart of the NNN universe — that is an unambiguously positive signal heading into the second half of the year.

One notable bright spot:
Cogent Bank in Orlando, Florida, has launched a business to finance single-tenant net lease properties from coast to coast
, an example of the niche institutional capital that is actively seeking NNN product. Specialist lenders like this often provide the most competitive terms for mid-market NNN deals in the $2M–$10M range that first-time buyers typically target.

How Cap Rate Trends Interact With Your Net Lease Financing Strategy

Cap rates and financing costs do not move in isolation — and understanding their relationship helps you time acquisitions and structure deals more intelligently.
Net lease transaction volume is expected to remain steady in 2026 as buyer and seller pricing expectations continue to converge, though the path to further Federal Reserve rate cuts has narrowed to a single reduction anticipated for the year amid persistent inflation concerns.

Pricing is stabilizing after 2024–2025, with The Boulder Group forecasting 10%–15% transaction volume growth in 2026 as bid-ask spreads narrow.
That convergence creates a window: sellers have become more realistic on price, and buyers can now pencil deals with confidence that values are not moving sharply against them after closing.

For investors focused on yield, the bifurcation in the market is your roadmap.
Premium tenants such as McDonald’s (4.30%–4.60% cap rate on 15-year leases), Chick-fil-A (4.20%–4.50%), and Wawa (4.90%–5.20%) command the tightest cap rates, while tenants including Dollar General (6.75%–8.50%) and Family Dollar (7.80%–8.20%) offer elevated cap rates for yield-focused investors.
Your financing strategy needs to match your yield target. Buying a McDonald’s at a 4.4% cap rate requires different loan math — and different lender conversations — than buying a Dollar General at a 7.5% cap rate.

If you are ready to run those numbers against live deals, view available NNN deals across a range of tenant types and price points to find properties that match your return target.

How to Stress-Test Your NNN Deal Before You Borrow

First-time NNN buyers often model their deal at one interest rate scenario and stop there. Experienced investors run three: the base case, a rate-up scenario, and a refinance scenario at lease expiration. Here is how to frame each one.

• Base case: Model the deal at today’s all-in loan rate (roughly 10-year Treasury + 175–200 bps). Calculate your cash-on-cash return after debt service. If you are positive-leveraged (cap rate exceeds loan rate), the deal is generating yield above your cost of capital.
• Rate-up scenario:
  For every 100-basis-point change in the 10-year Treasury yield, retail cap rate movements average approximately 78 basis points
  — meaning cap rates tend to rise with rates, which protects asset values somewhat in a rate-up environment. Still, model a 50-bps rate increase on any floating-rate debt to ensure your DSCR stays above 1.20x.
• Refinance scenario: If your loan has a 10-year term and the lease runs 15 years, model a refinance in year 10 at a rate 100 bps higher than today. Does the deal still work? For investment-grade tenanted properties with rent escalations built in, the answer is usually yes — because the higher NOI at refinance partially offsets the higher rate.

Once you have run this analysis, connect with a specialist advisor who can benchmark your assumptions against current deal comps and help you identify which lender channel makes sense for the specific property type and tenant you are targeting.

Frequently Asked Questions

What loan-to-value ratio can I expect on a NNN property in 2026?

For investment-grade tenanted NNN assets with long lease terms, lenders typically offer 60%–65% LTV. Some CMBS and life company lenders will reach 65%–70% LTV on premium credits. Average commercial LTV ratios improved to approximately 60.9% across the market in Q4 2025, reflecting a modestly more accommodating lending posture heading into 2026.

How does the 10-year Treasury affect my NNN financing rate?

Most fixed-rate NNN loans are priced as a spread above the 10-year Treasury yield. With the 10-year currently around 4.4%, and typical spreads of 175–200 basis points, all-in rates for well-qualified NNN borrowers are generally in the 6.0%–6.5% range. Stronger tenants and lower LTV ratios compress the spread and lower your rate.

Is positive leverage possible on a NNN deal right now?

Yes — particularly on deals with mid-range tenants where cap rates are in the 6.75%–8.5% range. If your all-in loan rate is 6.0%–6.5%, buying at a 7.0%+ cap rate creates positive leverage where each dollar of debt you add increases your cash-on-cash return. Premium tenant deals (cap rates below 5%) typically require higher equity contributions or acceptance of neutral or slightly negative leverage at acquisition.

What is the best loan structure for a first-time NNN buyer?

For first-time buyers, a 10-year fixed-rate bank balance-sheet loan or a life company loan offers the most predictability. CMBS loans can offer competitive rates and higher LTVs but come with strict prepayment penalties and limited flexibility. Start with a fixed rate and a loan term that comfortably falls within the lease term to minimize refinancing risk at maturity.

How does tenant credit quality affect my financing terms?

Dramatically. An investment-grade tenant (BBB- or higher from S&P) signals to lenders that rental income is reliable, which typically unlocks lower loan spreads, higher LTV ratios, and more lender competition for your deal. Non-rated or franchisee-backed tenants may require lower LTVs and carry wider spreads — directly increasing your equity requirement and reducing your levered return.

Can I use a 1031 exchange to buy a NNN property and still finance part of it?

Yes. A 1031 exchange only requires that you reinvest the net equity proceeds from your sale — you are not required to buy all-cash. Pairing 1031 equity with a new NNN mortgage is a common and effective strategy. The new debt does not need to equal or exceed the old debt in most exchange structures, though working with a qualified intermediary to confirm your specific scenario is essential.

Bottom Line

Net lease financing and interest rates are not obstacles to NNN investing — they are the tools that turn a solid deal into an exceptional one. With cap rates at 6.80% across the single-tenant sector, lenders returning to the CRE market in force, and CMBS issuance at its highest level since 2007, the debt environment in 2026 is working in buyers’ favor. Structure the financing intelligently, match your tenant credit quality to the right lender channel, and stress-test your returns before you commit. When you are ready to move from theory to live deals, take a look at some of the deals currently available across the NNN market.
