> Not recognizing that they are the problem.
How are they the problem? They bought one house and occupy it as a family. That's fair play by anyone's measure, I'd think.
If more other people want to move into the town than there are units of housing for them and, as a result, bid up the housing that's available, it's not the fault of the people in the town who bought one house 10 years ago and have lived in it for those 10 years.
We bought our place in 2007 (and lived in it continuously). It's worth roughly 2x what we paid for it. That's a CAGR of just under 5% per year. Was that a good investment? Hard to say, but let's look: The S&P total return was a CAGR of 8.5% over that time, but would have been 8.5% CAGR on X (downpayment amount) or about +2.4X. The house was 4.8% CAGR on 5X or about +5.4X.
Along the way, we've spent around 0.8X on repairs, improvements, and maintenance that I can think of and around 1.1X on taxes and insurance. Mortgage interest (after taxes) was another several X. Our house is vastly more pleasing to live in than our old apartment was and we've had two kids and a dog here comfortably for 15 years. The non-financial aspects dominate the financial aspects, but for a property that's appreciated about inline with inflation, it's been OK financially and great psychologically.
