Gross Leases

• This type of lease often contains an escalation clause that allows the landlord to increase the rent annually to offset increased expenses.

Step Leases

• The rent is increased at a set amount on an annual basis during the life of the agreement.
• The increase is to cover the landlord's expected increases in expenses.
• The increase is based on estimated rather than actual costs.

• The rent is tied to rises in the cost of living.
• The rent goes up with general inflation.

Net Leases

• The tenant pays a base monthly rent plus some of the expenses.
• The increases are based on actual costs rather than on estimates.
• The rent increases at the time that the landlord incurs an increase in costs.
• In some cases, the tenant pays rent plus all of the real estate taxes.
• If leasing only a portion of the building, the tenant will pay a proportionate share of the taxes.

Net-Net Leases
