Example – Calculate the tenant a percentage (%) of the rent of his turnover instead of a higher monthly amount. So if the tenant makes money, you will benefit from it too. A commercial lease is a contract for the lease of retail, office or industrial premises between a lessor and a tenant. The tenant pays a monthly amount to the lessor in exchange for the right to use the premises for commercial purposes. Commercial leases are usually longer than housing types, between 3 and 5 years, and it is common for the tenant to have renewal options at predetermined monthly payments. The first three spaces concern the date on which this lease is concluded. Here you need to enter the calendar date of the first space, the month for the second space and the year for the third space. .
