Translate a Mortgage Offer Into the Total Cost of What You Are Buying

The monthly payment looks manageable. The question is what you are paying in total for a property over 25 years. This translates the offer into total interest, what happens when the initial rate ends, and what the full cost of the purchase actually is.
