At least you can’t get kicked out or have your rent raised for arbitrary reasons. Some renters are basically moving every year.
Mortgages can change repayments amounts as the central lending rate changes.
We’re in a squeeze in Canada right now because rates went up and a bunch of mortgages are up for renewal. (5-year fixed rate is standard here)
In Spain you can decode between fixed or variable rates, and although fixed rates are usually a bit higher, having the peace of mind that suddenly the mortgage won’t raise next month and being able to plan around a fixed monthly cost is such a big peace of mind.
Fixed rates are the best.
It went up a little, but nothing compared to the equivalent in rent you’d pay for the same place.
