My understanding was that long-term fixed rate mortgages were not common at all outside of the US and like France.

This is from 2010 but has some good charts. https://business.sdsu.edu/_resources/files/real-estate/resea...

Anecdotally it meshes with some things I've heard elsewhere but don't hold me to it:

- Canadian mortgages are typically something like 5 years.

- UK is similar, it's either variable, or fixed for something super short, like 2-3 years.

- Australia same kind of boat, most are variable, I've heard the interest rates during covid temporarily reversed the trend, but same deal, they're only fixed for a few years.
