Which lease involves rent increases based upon the appraised value?

The lease that involves rent increases based upon the appraised value is the reappraisal lease. In this type of lease, the rental amount is adjusted periodically based on new appraisals of the property’s value. This means that as the property's market value increases or decreases, the rent will be recalibrated accordingly based on the outcomes of these appraisals, allowing the landlord to capture the changing market conditions over time.

Other lease types, such as a graduated lease, typically involve a predetermined schedule for rent increases, meaning that the increments are set from the beginning rather than tied to appraisals. Similarly, a net lease primarily concerns the allocation of property expenses like taxes and maintenance along with base rent, rather than adjustments based on property value. A sale-leaseback arrangement involves selling a property and then leasing it back, which is an investment strategy rather than a structure for adjusting rent based on appraisal. Thus, the reappraisal lease is specifically designed to link rent to the appraised value of the property.
