Case Study: $2.94M AutoZone NNN Financing in Tucson, AZ: Bank Beat CMBS for a 1031 Exchange Buyer

The Property

The subject property is a freestanding auto parts retail building in Tucson, Arizona, occupied by a national investment-grade auto parts tenant on a 15-year absolute NNN lease. The building totals approximately 7,000 square feet on an out-parcel pad site with strong road frontage and dedicated parking. The Tucson location sits within an established commercial corridor serving a dense residential base in the surrounding trade area.

Annual net operating income at acquisition was approximately $214,000, producing a 5.10% going-in capitalization rate on the $4.2 million purchase price. The lease is absolute triple net with no landlord responsibilities for taxes, insurance, or maintenance. Rent escalations of 10% occur every five years throughout the primary term and renewal options.

The Borrower

The buyer is an experienced private real estate investor completing a 1031 exchange from the sale of an apartment building in the Phoenix metro. The investor had identified the AutoZone as a replacement property within the 45-day identification window and needed to close within the 180-day exchange deadline. This was the investor's first single tenant net lease acquisition after transitioning out of active multifamily management. No borrower name or identifying details are published per CLS CRE's privacy policy.

Why Bank Financing Beat CMBS at Sub-$5M

CMBS conduits dominate the conversation in NNN financing, but at loan amounts below $5 million, the economics rarely favor securitization. On a $2.94 million loan, CMBS securitization costs create meaningful friction that erases the rate advantage. CLS CRE evaluated both execution paths before placing this deal with a national bank that operates a dedicated STNL program.

• Speed: The bank closed in 31 days. CMBS conduits typically take 60 to 90 days: this deal would have missed the 1031 exchange window entirely.
• Closing costs: CMBS adds legal fees, securitization costs, and rating agency expenses that compress the effective pricing advantage. On a $3 million loan, these fixed costs are more punishing than on a $20 million loan.
• Prepayment flexibility: The bank offered a negotiated step-down prepayment schedule. CMBS would have required defeasance or yield maintenance with no flexibility for a future sale or refinance.
• Minimum loan size: Most active CMBS conduits prefer loans of $5 million or above. Below that threshold, execution quality declines and pricing softens.

The bank program, accessed through CLS CRE, priced the loan at CMT plus 230 basis points: producing a 7.25% fixed rate: with a 25-year amortization schedule and a 5-year term. Recourse was required at 70% LTV, which the borrower accepted given the clean lease structure and investment-grade tenancy.

The Underwriting

The deal passed every underwriting threshold with room to spare:

• Loan to value: 70% (at the program maximum; non-recourse available below 60%)
• DSCR: 1.42x on a 25-year amortization schedule (minimum required: 1.25x)
• Debt yield: 7.3% (adequate for investment-grade STNL)
• Remaining lease term: 15 years absolute NNN with four 5-year options (well above the 7-year minimum)
• Tenant credit: Investment-grade corporate guarantee from a national auto parts operator
• Building condition: Freestanding pad site in excellent condition, no deferred maintenance

Loan Structure

• Loan amount: $2,940,000
• Interest rate: 7.25% fixed (CMT plus 230 basis points)
• Term: 5-year fixed
• Amortization: 25-year schedule
• Prepayment: Step-down structure (negotiated; no yield maintenance)
• Recourse: Full recourse (70% LTV; non-recourse available at 60% and below)
• Origination fee: 1.0%
• Rate lock: 30-day lock from application
• Time to close: 31 days from signed application

What Made This Deal Work

1. Investment-grade tenancy with a long lease. A 15-year absolute NNN lease from a national auto parts brand is precisely the tenant profile this bank program is designed to fund. The corporate guarantee eliminates most of the credit risk the lender would face with a local operator.
2. 1031 exchange timeline met. The 31-day close was the critical success factor. The borrower had identified this property within the 45-day window and had less than 60 days remaining on the exchange clock. Bank execution was the only viable path.
3. Solid cap rate and DSCR relationship. A 5.10% cap rate with 70% LTV produces acceptable DSCR at the current CMT level. As cap rates have compressed in coastal markets, Tucson and other Southwest secondary markets have maintained cap rates that support financing at 65 to 70% LTV without DSCR concerns.
4. No structuring complications. Single asset, single tenant, corporate NNN lease, experienced borrower, no environmental issues. Clean deals like this close fast in the bank STNL program.
5. Negotiated prepayment schedule. The step-down prepayment terms give the borrower flexibility if they need to exit before the 5-year term matures: an important consideration for a 1031 exchange buyer who may want to redeploy capital again.

Key Takeaway for STNL Buyers

For NNN acquisitions in the $1 million to $5 million range, bank financing through a dedicated STNL program is almost always the best execution path: especially for 1031 exchange buyers who need speed. The CMT-based pricing at 190 to 260 basis points over the applicable term keeps rates competitive, and closing timelines of 30 to 40 days are achievable with complete documentation.

CMBS becomes the better choice above $5 million when non-recourse is required, when the deal involves a portfolio, or when a 10-year fixed term is important. Below $5 million, the fixed costs of CMBS securitization erode the pricing benefit.
