Final answer:
In a graduated lease contract, the means to determine future rent amounts involve reappraisal, indexing, and an escalation clause. The use of an ARM is not a means to determine future rent amounts.
Step-by-step explanation:
In a graduated lease contract, the means to determine future rent amounts involve various factors. Reappraisal is one method that involves reassessing the value of the property periodically, which can result in changes to the rent. Indexing is another method that links the rent amount to an external index, such as inflation. An escalation clause is a contractual provision that specifies how the rent will increase over time.
On the other hand, the use of an ARM (Adjustable Rate Mortgage) would NOT be a means to determine future rent amounts in a graduated lease contract. ARM is typically used in mortgages to adjust the interest rate based on market conditions, not rent amounts.
In a graduated lease contract, the means to determine future rent amounts usually include reappraisal of property value, indexes such as the Consumer Price Index (CPI) or other economic index's figures, or an escalation clause which specifies how rent will increase over time.
However, the use of an Adjustable Rate Mortgage (ARM) would not be a method to determine rent in a graduated lease contract since ARMs pertain to the financing of property purchases rather than rental agreements.
