Younger millennial and tool until my late 20s to buy a house with my partner. I would want to be comfortable knowing I can support them as an adult as well if necessary before having them.
Largest concern by far is the mortgage, nothing else even close to compared to that as an expense. Without a mortgage we could work 3 days a month each and life would be easy.
I was unemployed for a long time after leaving school before I could find something. I don't know how to get away from that fear of what if I lose my job and can't find another one after a few years and my savings run out?
