When I was age:19 it was possible to buy a very decent home for 3x annual income

I worked full time during uni on a good starting salary, but that salary would be achievable for anyone willing to work 2 jobs or overtime

You could save up a 20% deposit in a matter of months if you were serious about it ( I didn’t because our government was paying first home buyers thousands of dollars to buy a house at that time, so I didn’t need to)
