each simulation process while dynamic variables change based on the user‘s desired range for the
variable. In order to minimize model complexity, the number of algorithmically controlled dynamic
variables is limited to only three out of the possible seven available. Dynamic variables include: rental
income, property price, capital expenditures, operating expenditures, loan-to-value (LTV), debt rate and
equity-risk premium. For example, the user may select a combination of rental income, debt rate and
LTV as the three dynamic variables. Each would serve as the designated dynamic inputs for the
simulation process. The operational semantics and how each variable impacts the model will be
explained in the ROE-simulation screen below.
