Fixed Interest Rate

See: Fixed Rate.

And you should be...interest-ed in it. When an interest rate is fixed, it doesn't move. Like...start that mortgage at 5% and then rates go up? Well the adjustable interest rate mortgage people will be paying 9, 10, 11% a decade from now, while you're sittin' fat 'n' pretty, still paying you the 5% fixed interest rate...rate.
