Many are fixed for the entire duration of the mortgage&#x27;s length (e.g. 25 years). You can find variable rates as well though.<p>Being from Canada, I couldn&#x27;t believe that this was possible when I first came down here because it seems to defy belief that any bank would take on the risk to extend a loan at such low-interest over that kind of time frame. It turns out that it&#x27;s possible because the banks aren&#x27;t taking any risk; instead it&#x27;s all outsourced to US taxpayers ;)
