👉 "Spend 30% more on rent and still have to pay mortgage, I'm feeling a bit like a canary in the coal mine."
In this scenario, we use "can mortgage payments go up" as a profanity slang word that refers to the idea that, despite paying higher interest rates or other fees, the amount of money someone actually pays on their mortgage stays similar or even increases. This conveys a sense of alarm and discomfort with how much more an increase in mortgage payments could mean for people who are struggling to make ends meet.
