Custy - I also think it depends on where you buy - our homes have all been within 30 minutes tops of Plymouth, due to dh's work, and as prices there aren't as huge as they are elsewhere in the country, we could afford to trade up.
We could not for instance, afford anything like we have in Cornwall elsewhere, in Hampshire for instance. I often drool in the windows of the estate agents in Winchester or the small village where mil lives.
Yes, dh has a fairly secure job in that he survived the redundancy round in the RN last month, and the next tranche isn't until next year. He doesn't have long left to serve until he has to retire, so there are not enough savings for the MOD to make him redundant at the moment.
I agree it's hard, but it has always been hard, as Xenia said, and you know, high interest rates, no help with childcare, having to pay an extra insurance for a high LTV, compared to low rates now and tax credits and it seems greater lending multiples. I also agree that a lot is luck and circumstance. However, planning as much as you can helps.
I don't think that turfing the elderly out of their homes will help, as the prices they would want would still be unaffordable; there is the problem of ring fencing your assets against care home fees; the desire to leave an inheritance to your kids (otherwise why bother to aspire at all?), and of course many can take out loans against their homes that pay off on their death and the sale of the house, so the property can still generate an income stream.
