Frequently Asked Questions
A NNN industrial leaseback is a transaction in which a business sells its industrial property such as a warehouse, distribution center, or manufacturing facility to a private investor and simultaneously leases it back under a triple-net lease. The tenant pays all property taxes, insurance, and maintenance costs, while the investor receives long-term, passive rental income with no operating expense obligations.
NNN industrial leasebacks offer investors fully passive income with no landlord expense obligations, long-term lease terms typically ranging from 10 to 25 years, creditworthy tenants who are operationally anchored to the facility, and contractual rent escalations that build inflation protection into the income stream. Compared to multifamily or retail properties, industrial NNN leasebacks require minimal management and deliver highly predictable cash flow.
Experienced principal investors typically require a minimum remaining lease term of 10 years on NNN industrial leaseback acquisitions. Lease terms of 15 to 25 years are strongly preferred, as they provide extended income visibility, reduce re-tenanting risk, and maximize the asset’s value for long-term capital preservation strategies.
Industrial properties commonly used in sale-leaseback transactions include warehouses, distribution centers, cold storage facilities, light manufacturing plants, and fulfillment centers. The strongest candidates are single-tenant facilities with modern specifications high clear heights, dock access, and proximity to major logistics corridors occupied by creditworthy operators for whom the facility is a core business asset.
In a NNN leaseback, the investor’s entire income stream depends on the tenant’s ability to pay rent for the full lease term. A long lease signed by a financially weak tenant is a liability, not an asset. Creditworthy tenants typically established national operators, publicly traded companies, or large private businesses with strong balance sheets provide the income security that makes industrial NNN leasebacks one of the most reliable long-term investment structures in commercial real estate.
