Not a alot of work for this one but it was quite interesting.
Took a semi-functional and falling apart mortgage calculator and brought into a working state. While their adjusted some of the html for the calculator form and brought it up to web standards.
Some fun formulas had to be drawn as it isn't your standard calculator.
Thanks to The West Harbour for this one. Hopefully we could get the whole site to revamp and bring up to code as well someday. That would be super fun as well!
