Triple Net Lease

In a triple net lease the renter pays rent, plus the real estate taxes, plus the insurance, plus the fees for maintaining the common area.

Since the renter has to pay so many other expenses, the rent itself is generally lower than it would be if the building’s owner were paying the extra costs.
