My understanding is you buy a house with a mortgage and you pay of the mortgage before you retire and so in your retirement the biggest expensive being (your mortgage) has gone and you can live on your pension which is less than your earnings were.
We rent privately as we cannot at the moment get a mortgage to buy a house. I have been perfectly happy with this, prioritising being happy, spending time with my family etc above earning money to save up for a deposit to buy a house I don't want and to pay for all the legal fees for things I don't understand.
I don't work I stay at home with my children and when they are old enough to go to school I don't plan to work as I would like to home school them. My husband works hard and we live comfortably on his salary but it's still one persons salary providing for a family - not much left over for saving up.
I wonder if I have a responsibility to plan for the future a little more, spend less on days out and experiences for us, perhaps get a job, consider myself unable to home school the children as we are not in the position to have me not working

Does anyone have anything I perhaps am not taking into consideration?
