A $2200/mo mortgage on a $65k salary does indeed sound like a stretch. But even having a mortgage at all at 24 is pretty impressive, and he's probably still a ways off from his peak earning potential. Then he might have a bit more income for discretional spending.
In short - yeah it's a grind, but it sounds like he's making responsible decisions and hopefully they will start to pay dividends in another 5-10 years. And your 20s is when you are most able to grind it out - before kids (if that's something you want) start demanding a huge chunk of your time and energy, and before work starts to feel like a slog after you've been at it for 20 years.
