They do, but they are typically only a couple years. The variable rate has been popular for a long time.

In Finland, most go variable too. I collared the moal on ours for 10 years (the max) so it can only rise so far. This comes with an additional cost, and many people think me crazy. I am old enough to remember the early 1990s and with the rates so low now, it is a no brainer. They can only go a fraction lower, but there is a lot of potential on the rise side.
