First of all, I am aware that there is a 99.9% chance that this is a very stupid question.
But I'm going to ask it anyway..
With lots of talk of raising interest rates soon and so many people will be defaulting on their homes because of it, why aren't they already in a fixed loan? What are these nervous easily broken people holding out for? More good times? Should I have waited? What am I potentially missing out on here that I should of risked it all waiting for?
This isn't correct. If you fixed middle of last year, you have 4 years of winning rates.
You just have to do your own calculations for your situation. Whether you have a large offset etc.
