If the parties involved in a rent review cannot come to an agreement on the new rent amount, the resolution process typically depends on the terms specified in the lease agreement.
In such cases, the lease may outline alternative mechanisms for determining the new rent. Mechanisms could include options like arbitration, mediation, or the involvement of independent experts or valuers to assess and set the new level of rent based on prevailing market conditions.
If the lease does not specify a particular resolution process, it may be necessary to seek legal advice or engage in negotiations to find a mutually acceptable solution.
Ultimately, the specific course of action will depend on the lease terms and the willingness of the parties to work towards a resolution.
