There really is no pressing need to ever own a house. What do I get with ownership over renting? Sure, the mortgage payments might be cheaper than a given rent, and perhaps the local housing market might work in my favor, but perhaps it won't!
I might one day own a house, but that's not going to happen for at least a decade or more until my position rises from entry level to middle to a high-enough level where I actually have the liquid capital for a down payment on something worth dealing with a long term mortgage for, and have enough money set aside to deal with potential catastrophic repair or even just regular maintenance. Right now, if I come home and my roof is caved in, the floor is flooded, or my PSU explodes away half the house, I'm gonna shrug and call my landlord and renters insurance agency, and let them solve all these catastrophic problems on their time and their dime/
I'm in no hurry to get one, so I don't see a point to save specifically for a house at the expense of efficiency (spending 15 minutes to order and eat a meal vs. 1hr+ cooking one), or other more fruitful investment opportunities than home ownership. Not to mention, it would make moving around for better employment much more involved and stressful if I had a house I needed to sell or rent out in order to leave the city.
