A triple net lease (NNN) is a type of commercial real estate lease where the tenant agrees to pay not only the rent but also three additional expenses: property taxes, insurance, and maintenance costs. This arrangement shifts many financial responsibilities from the landlord to the tenant, making it a popular choice for investors seeking stable income. In a triple net lease, the landlord typically has less involvement in property management since the tenant handles most operational costs. This lease structure is common in properties like retail spaces and office buildings, providing a predictable revenue stream for landlords while allowing tenants to have more control over their space.
