I need a mortgage refinance comparison tool for a Web site. Essentially the same calculator that is found on [url removed, login to view] and www.championmortgage.com. The user inputs their loan amount, monthly payment, and state. Then they are shown a potential new monthly payment (if the new payment is going to be lower than their current payments), as well as invitation to fill out their information (basic form e-mail to be sent to my account).
The results table should show the new payment, the savings, the mortgage rate and loan terms.
The calculator needs to be flexible. As mortgage rates change, we'll need a way to easy adjust them. A simple password-protected admin control panel will suffice. It should allow us to quickly and simply change the rates used in the calculation, as well as the destination e-mail address being used in the results form.
Any questions, just ask. Thanks.
