I doubt anyone could buy a house on my first wage. I was a farm hand, worked 84 hours a week, 7 days a week, and earned an actual pittance as an apprentice. I even had to pay the farmer for my accommodation out of the pittance. I saw the light my first year and joined the military, which was the best decision I ever made as a young guy and possibly in my life.
I did buy the house my partner stole from me after I left the military, but only because military service allowed me to get a very low interest mortgage.
