Times have changed. When my parents were in their twenties, they were buying their first house, having kids, and starting up the (relatively certain) career ladder. If you're in your twenties today, there's no way you're thinking about either of these because you're saddled with six figures of student loan debt, and do not have the employment certainty it takes to take root in an area to buy a home.

There's still plenty of people still doing exactly that. Get out of the HCOL areas and there are tons of people going to an inexpensive state school and buying a house in a new suburb outside of Boise Idaho or wherever.
I bring up Boise because I did an internship with Micron 5 years ago and other interns were meeting with realtors so they could buy a house as soon as they graduated.
