Do I ever seriously think about moving out?
No, not really. My mother divorced my elderly father and practically took him to the cleaners. He doesn't have much of a retirement and he had to take out a loan to keep the house that he had paid off for thirty years. With my father's retirement shot and his working years coming to an end, I'll likeley be needing to step up and either pay for part of the mortgage or all of it in the next couple of years.
So if I was to "move out", I'd basically be throwing away my father's house, which he paid off for thirty years and planned to pass on to his children. Not only that, but I'll probably be needing to subsidize my father in the coming years. So if I have a choice to spend a $1000 a month on a land lord, or to help my father retire and pay his mortgage, I'm going to help my father. In my particular circumstance, moving out would be a luxury, not a testament to hard work. I would simply be running away from my financial duties to my father.
I don't agree with moving out in general, but if I was going to do it, I'd do it practically. I wouldn't just do it because of peer pressure. I'd do it once I have a year's rent already saved up, once I had enough income to support my percentage of rent and once I was able to afford everything else that would go with living independently.
