Renting is a waste of money because you're building no equity, you're investing in nothing and you will never recoup that money. You're just throwing money away, which is exactly what I thought about buying a new car when you have an old car that still runs.

It was this realization that caused my next, even more adult-like decision: I am going to buy a house. I very casually started looking online at houses and then started to play with mortgage calculators, and had the light bulb moment where I realized that, not only can I actually afford to buy a house, but that it would be a really good idea.
