25 doesn't seem that crazy to buy one's first house. I bought my second at 24, and still have the first as a rental. And I make less than her (no student loans though).
I mean it's hard to argue with "work hard, save a lot, and buy property you can afford."
But "She drives an older car, a 2009 Ford Escape SUV with 'a big old dent.'" Uh...
I'm not saying she's an idiot or anything but it just doesn't seem too remarkable.
