£35k or £45k may have got you a terrace house "oop north" 15 or 20 years ago, but since the house price bubble of the early noughties you need to triple those figures. Not sure I would recommend busting a gut to get on the housing ladder to my son – houses are overpriced and will remain so for quite a few years it seems.
I never got any financial advice from my parents but I learned not to do what they did. So, no credit card, do not keep borrowing against the house to pay off other debts, etc. It's not free money, you have to pay it back one day.
The other things I have learned the hard way myself are:
1) there's no such thing as an independent financial advisor
2) endowments were a crazy idea
3) many pension schemes aren't much better
It all seems very complicated when you're starting out with houses and pensions and stuff in your twenties and you tend to listen to advice. I would now advise not to take advice, but to find out everything for yourself – it's not as complicated as the financial industry likes to make it sound.
