Each time a commercial lease is reviewed to ‘market rental’, the essence the operation is to determine the fair and equitable rent that could be of benefit and fairness to their landlord and the tenant because of the prevailing market conditions at that time. Its interesting to observe the review process and it is effectiveness today. Firstly, it needs to be asserted all leases are potentially different in regards to the best way rent articles are implemented. That is why you should read the lease you are using to view what sort of rent review clause really works and what methods are to be adopted at different times. Take particular care in noting the critical dates in the way. Some lease clauses are created with all the intention that ‘time is within the essence’, as well as the parties into the review are thereby required giving answers to each other within certain time frames. Secondly, rent surveys are done in several different ways at different times some leases. The processes of review and increase are by way of example, CPI, a hard and fast %, a fixed amount, and market rent. Sometimes the review process may be a combination of both, such as CPI plus 2%. All of this is defined out and explained inside the lease.
