Abstract
Buetow and Albert (1998) discuss options embedded in lease contracts. They present a pricing framework, calibrate it using data from the National Real Estate Index and apply it using a numerical method known as the finite difference method with absorbing boundaries. In this note the analysis is extended. Firstly, analytic solutions are presented. Secondly, some of the findings are discussed. Finally, the framework developed by Grenadier is used to compare indexed renewal options for different lease lengths.
