I am designing a website to do with properties, and I would like to have a mortgage calculation on the site, to do this I need the right calculation formula for it.
The type of calculation I need is the same as findaproperty website in there mortgage centre page [url removed, login to view] which are:
How much can I borrow?
What will my monthly costs be?
What will happen if mortgage interest rates rise or fall?
How much will I pay in stamp duty when I buy a property?
How much can I borrow on a buy to let mortgage?
How much rent do I need to charge to finance a buy to let mortgage?
I need to know the calculation script they use, and a the formula.
