Refurb_Rate = Convert.ToInt32( totalRefurb / totalUnits * 100); //This is where I try to perform the cast.


this does not make sense, as all variables are declared integers, therefore the quotient will be integer too, and the Convert method does nothing for you.

Furthermore, the result will not be what you expect:

for totalRefurb=2, totalUnits=10, the formula looks like 2 / 10 * 100, unfortunately in an integer world 2 / 10 is zero.
What you need to do is one of the following:
- multiply first, i.e. 100 * totalRefurb / totalUnits
- use real numbers (i.e. data types such as float or double), this will avoid overflow (when your integers near the max value), and perform rounding.
