I got out by 19 and got a roommate and my first apartment.
My cousin whose the same age stayed at home through college and even after he graduated.
After a rough spell I was sleeping on my moms couch for 9 months at 24, until I could get a different job and save up, find a new roommate etc.
At 25, my cousin moved out and straight into a condo that he bought. He’s never known what rent is or had roommates.
My sister in law and her husband did the same thing as my cousin, almost identical actually, and the first place they moved out to in their mid 20’s was a condo they bought together….they have never known rent or roommates.
Eventually I got it all worked out and turned into a responsible, bill paying homeowner….but I also know that I got a little lucky as I stumbled into some things that helped me find a career, let alone the role my sex and my race played in making it as easy as possible to move up.
If I could chose it for my son, I’d have him stay home through college, start a real job and start saving for that down payment and skip that renting life if possible. I’m the two example I saw first hand, it certainly looked easier than what I did lol.
