He needs to learn some empathy. But it is easy to feel a sense of relief when you're in a good position and an even better one if it goes to pot. I've 4 years left of a 5-year fix term at 2% for half the value of the house. I'm also on a Help-to-buy loan which was at 40% of the value of the home. We just paid off a big chuck of that so now we have a loan that's worth 23% or so. The price of our house only rose 5% or so in the last 6-years
The kicker is, if there a big house price crash, we actually benefit because the actual monetary amount we owe reduces, and the bigger the crash, the less we owe. If there is a house price crash and we go into negative equity and time it to pay off the rest of the loan at the lowest point, we actually MAKE money off the loan because we owe less money than we actually borrowed!
We're not looking to move as this is our forever home unless we win the lottery or some other such luck so we're not stuck or anything.
But after saying all that, i certainly don't want to see others suffering, we've had our fair share of a difficult life so we understand
