Triple Net Lease Meaning

A triple net lease is a real estate agreement where the tenant pays multiple property-related expenses in addition to the rent. The added expenses include maintenance charges, property tax, and insurance. It is an agreement between the lessee and the lessor.

It is also referred to as NNN lease (net net net), emphasizing the payment of three operating expenses. Therefore, the amount of rent is kept lower than gross lease agreements. In regular lease agreements, the owners take care of property tax, insurance, and maintenance costs.

If the cost of maintenance, insurance, and tax cross the limit, the landlord will pay part of the expense.

NNN is a great leasing option for landlords since they get rid of property maintenance fees, insurance, and taxes. However, to actualize these benefits, the lease must be long-term—10 to 15 years. A lease agreement should also have a clause for a yearly escalation in the lease amount to ensure optimum returns.

The formula for computing the lease amount in a triple net lease is given below:

Lease Amount = (Base Rent+Common Area Maintenance+Property Tax+Property Insurance)/12

Here, Base Rent=Rent Per Square Feet×Total Leased Area

The steps for determining NNN lease amount are as follows:

  1. First, find the base rent by multiplying the rent per square foot with the total leased area. If the rent per square foot value is given in monthly figures, multiply it by 12 to convert it into a yearly figure.
  2. Then, ascertain the yearly expense on maintenance charges, property tax, and insurance.
  3. Next, add up base rent, maintenance charges, property tax, and insurance.
  4. Finally, divide the result by 12 (Since we need to determine the monthly lease amount)

Andrea leases a commercial building of 10000 square feet to the business entity XYZ Ltd.— for office space. It is a NNN lease, and the ascertained monthly rent of $ 0.25 per square foot was charged. For the office, annual common area maintenance costs $1200, property tax costs $ 600, and the yearly real estate insurance payable costs $1200. Now, determine the monthly lease amount.


Lease Amount = (Base Rent + Common Area Maintenance + Property Tax + Property Insurance) / 12

Base Rent = Rent Per Square Feet × Total Leased Area

Base Rent = (0.25 × 12) × 10000 = $30000

Lease Amount = (30000 + 1200 + 600 + 1200) / 12

Lease Amount = 33000 / 12 = $2750

Thus, XYZ Ltd. paid Andrea a monthly lease amount of $ 2750.

The NNN lease has numerous advantages to the landlord and the tenant, as discussed below:

NNN lease disadvantages are as follows:

  • Tenants occupy the property for years—restrict landlords from using the property for other purposes.  
  • Many NNN lease agreements include fixed rent amounts—this eliminates progressive returns.
  • Tenants renovate and make changes. As a result, for re-leasing purposes, the property has to be rearranged for the new lessee.

Triple Net Vs. Gross Lease

In a gross lease, tenants pay a single fixed payment to the landlord (including rent). The landlord bears all other costs—property tax, insurance, maintenance, and other ancillary expenses.
