How often do people get fixed rate mortgages that end?

for example back in 2003 etc.. many people nailed down their current ARM in exchange for a low fixed rate.





how many of those deals expire after a certain length of time??





what percentage??





why so??





thanks for your answers!How often do people get fixed rate mortgages that end?
Are you asking if someone converts their ARM to a fixed rate, how long does the fixed rate last? Until the loan is paid off. The interest rate doesn't change.
