We must be a failure working in banks on low wages every man and his dog must earn more. 25k salary must be like 15k 10 years ago. Seems pointless working when the wage doesn't amount to anything meaningful.
Don't beat yourself up over it mate. I worry about the similar happening to us. I'm 37 and only just getting going in my career with my first decent promotion. I bought a housenjust before the recession and was stuck in negative equity until hast year when I sold it, despite not living in it for 11 years (long story).
We rent a shoddy 3 bed terrace but we're out in the sticks away from the cities so rent is reasonable but with every snag we get fixed I worry the rent is going to go up. We want to get a sizable deposit together, not throw money away renting but with the cost of childcare and energy bills I worry we'll be using our savings not building them. I also don't want to buy in this market and the bubble burst and be trapped like I was before.
Is your partner having reduced hours to reduce the childcare cost? If so, wouldn't it be better to suck it up and she pursue her career more? Big ask of course because obviously raising a child and being around is also important but it's another angle to look at.
Hope you get it sorted though, the world is ansillu place now and hopefully this bubble bursts soon.
