I graduated college in 2008 into the crash. None of my generation at that time knew that was coming. Couldn't get a job to save my life for more than 3 months at a time and making $8-10 dollars an hour which just let me pay for my cell phone-- I couldn't even buy a car. I remember at graduation we were looking at the economy and saying to each other "I hope I don't end up working at McDonald's" and then six months later cheering and celebrating with a friend for scoring a job at Chick Fil A because that was a feat! Every job required "experience".
I remember eyeing real estate then wishing but I couldn't even pay all my bills. The people a little older than me had already established jobs, and so they had "experience"; the ones younger than us had a little time to adjust, maybe adding a second major that was more resilient to the market.
Basically I'm 35 now and we have only just recovered and are in a good financial place for the first time. And now I'm starting, I'm hoping to buy a multi family this month.
But that's my personal story of why I didn't start earlier.
