I envy people who had the foresight to lock in their rates as I had a colleague who fixed in a 1.7% fix rate for 10 years on his home. He did have to hunt around and pay a decent amount for it.

I too bought my place during COVID and am one of those thousands of people who have come off a fixed rate to a variable rate, so the pain is definitely felt here too.

I believe fixed is slightly different from collared as the fixed rate doesn't change for the duration of it. But collared seems to be a fixed range that the rate can move in. So in Taraz's case, his rate could go below the 1.65% he has been paying......that's mind boggling when I think of my variable rate.....which is 5%+

I am doing what you are doing, all expenses on the credit card (sans the stupid places that charge you 2% to use a credit card) all savings in the offset accounts (yes, you can have multiple offset accounts set up) then pay my credit card bills a few days before they are due. A bit of work for sure, but the perception of beating the bank is worth it!
