A triple net lease (triple-net or NNN) is a lease agreement on a property whereby the tenant or lessee promises to pay all the expenses of the property, including real estate taxes, building insurance, and maintenance. These expenses are in addition to the cost of rent and utilities.

Who pays the mortgage on a triple net lease?

Property Mortgage: If you finance your triple net property, you'll be responsible for paying the monthly mortgage, along with any financing fees or interest over the term of your loan.

How much does triple net add to lease?

Now we have to add on the NNN cost which may range from $1 to $20 a square foot based on the use and costs. It is typical to see a $3 a square foot NNN cost in my area, which would add $15,000 a year or $1,250 a month to the costs. Your base lease rent of $4,166.67 could easily turn into $6,000 a month actual cost.
