Zero Cash Flow Deals — the NNN Structure Built for Debt

The strangest product in net lease: deals engineered to produce no cash flow — every rent dollar pre-assigned to debt service — bought eagerly by a specific buyer for specific reasons. Understanding “zeros” explains a corner of the 1031 market nothing else does.

The structure

Take investment-grade, long-term paper (classically Walgreens, CVS, dollar-store portfolios), finance it with credit-tenant-lease debt at maximal leverage (85-90%+), and match amortization exactly to rent: the tenant effectively pays off your mortgage over the lease term. Owner receives nothing monthly; owner’s equity compounds through principal paydown from someone else’s checks.

Why anyone wants this

Debt replacement, mostly: an exchanger selling highly leveraged property must replace the debt or eat boot — and zeros deliver enormous debt per equity dollar, solving in one purchase what would take several conventional deals. The paydown-readvance feature completes the trick: many zero structures allow re-borrowing paid-down principal tax-free (loan proceeds aren’t income), converting locked equity into spendable cash mid-hold without a sale. Add pure depreciation shelter and hands-off ownership, and the product fits: high-debt exchangers, tax-driven holders, and estates running the step-up clock on autopilot.

The prices paid

No income for years (the point, but still); refinance-market dependence baked into any readvance plan; thin buyer pools at resale (you’ll sell to another debt-replacement shopper); and total dependence on the single tenant’s credit for decades — a zero with a troubled tenant is a bond in a workout. Pricing runs tight because the CTL debt does the underwriting.

The fit test

Zeros are a tool, not a portfolio: right for the exchanger with a debt problem and an income surplus, wrong for nearly everyone shopping on yield. If your 1031’s debt math is forcing bad conventional choices, ask about the zero market — it exists precisely for that conversation.
