I always find these threads rather depressing. I'll be 65 before my mortgage is paid off, and I haven't got a large or expensive house either.
DH and I are both public sector workers, so neither of us get overtime, or large salaries. With no real payrises in the last ten years for either of us, overpayments is not really an option.
We haven't got a large house, but have moved twice. We extended the length of mortgage both times to pay for it. However, we're of an age where our first house was about £100k and our current house is worth about £300k. Still one of the cheapest three beds in the area.
However, DH and I both have good (part final salary) pensions, so we will have a comfortable retirement.
And before people say, no I don't buy a daily £3 coffee - live rurally, so not an option, no flash cars or expensive holidays etc....
But we have enough and a good life so aside from these threads, I'm generally happy.
