Quote from @John McKee:
NNN leases are not absolute NNN leases. Yes absolute is a term in the industry. A lot of properties are advertised as NNN, but you have to read the lease to understand what is actually covered. So for example: NNN usually refers to taxes, insurance, and maintenance. How do you define maintenance in the lease? Does maintenance factor in replacement costs of the HVAC, Roof, Glass windows, structural piping, Parking lot repaving, sprinkler systems, etc. How much of the structural part of the space is covered by the tenant?
Sounds like capex as opposed to operating expenses which are usually left out of NOI for all asset classes.
Example for multifamily- My 4plex had a tenant in one unit paying $24000 annually of which I achieved $14,000 annually NOI after taxes, insurance, yard work, common area utilities. After the tenant was there for 3 years they moved out. It was trashed, I had to repaint, redo carpet, cabinets, holes in the walls etc. It cost me $10,000 to renovate and 2 months of lost income so effectively $14,000. I just lost ONE FULL YEAR OF NOI on the 3 years leased to that tenant.
When I sell that property, it will be listed as $14,000 annual NOI for the unit. The next investor takes the risk.
I'd rather go with a NNN lease property even if the lease isn't iron clad.
