A perspective from an American:
- Yes, typically we can refinance whenever we like, _but_ it extends the mortgage for a 30 year term, along with additional direct immediate costs (plus human inertia). Unless interest rates were alarmingly high for your last go-round (ehem), you're directly incentivized and indirectly likely to not do so.
- I own properties in Canada (yay Commonwealth!). The notion of a 30-year fixed does not exist. One can get a 25-year amortization, but typically only with a 5-10 year guarantee for a fixed rate.
- As an American, Canadians are insane for buying into this system. Our system is so much more favorable to anyone with good enough credit to be approved for a loan it's literal comedy. Also our standards for approving someone for a loan seem to be lower (that said, I had no credit history in Canada when I started this adventure, so perhaps residents get a better deal).
- As a property investor, I'm happy to control for the cash I sink into my investments in interest versus the returns I get from rental revenue. Combining that with exchange rates and US interest rates versus Canadian, I <3 Canada.
- Fully variable interest mortgages are for suckers (and in that regard, I do have some regrets).
(bias: I <3 Canada regardless -- I'd live in Whistler, BC if circumstances allowed)
