Just off the shelf, in the US, you tend to have access to 10, 15, 20, and 30 year fixed rate mortgage. Variable rate mortgages used to be pretty common, but they're nearly non-existent anymore.

When we shopped to refinance, there were no adjustable rate mortgages to be found, only fixed rate.

Anyway, what we saw was that, depending on who you finance through, you can get a term anywhere from 5-50 years.
