Why a seller cares

Under a triple net lease the tenant pays taxes, insurance and maintenance on top of rent, so the owner's income is nearly all profit. Buyers pay a premium for a good NNN tenant, and the lease's remaining term is most of the value.

A simple example

Your small retail building is leased NNN to a national tenant with eight years left. Buyers price it on the rent and the credit of the tenant, almost like a bond.

A triple net building sells on its lease. The building itself is almost secondary.

What people get wrong

That NNN means the owner has no costs. Roof and structure usually stay with the owner, and the lease says which.
