I am very lucky that I got only 25% to pay left on my GTA suburb detached house - got it 12 years ago just before prices went cuckoo for cocoa puffs - but even then the variable payments are getting outta hand. Already thinking of doing some drastic changes to our lifestyle in order not to deplete our rainy day fund.
I had to go back and check. We are only 1 year into interest rate hikes. The maximum effect is probably going to be around year 3 or 4 when the majority of low interest mortgages have renewed into high interest.
Good luck for yours. Things are going to get expensive!
