People also need to think carefully when they say “DH/I can give up work” or “we can go part time”.
There are implications in doing this, £250k when a bulk of that has already gone on a big mortgage pay off doesn’t leave a huge amount left to live off for the rest of your life.
I am in a similar position to you, OP. Have paid mortgage off. That is fantastic and we are very lucky but god, life is expensive these days and while it’s great knowing we Have a roof over our heads (and savings in case that roof needs replacing), DH and I are both still working full time, in our mid 40s. I would never give up work at this stage, it’s far too early, you don’t know what could happen. I DO want the option to retire at 55 though, and this is quite likely if I keep working now.
Also the urge to switch to part time working - it’s something I would have considered when my kids were younger and more dependent, but you have to remember that pension contributions will also go down if you only work part time.
If I were you I would pay off your mortgage, replace any knackered out cars, use up your ISA allowance then put some aside in various savings accounts (research this) and WAIT. See how your outgoings change after you have paid your mortgage off. Unless your mortgage was a massive each month you may find that you don’t feel hugely better off at the end of the month, just more “comfortable” and less stressed, with more available to put towards weekends away or whatever, or more meals out a month than you had before. Kids seem to cost much more as they get older, school trips and uni costs loom.
Wait, watch, research and then make your decisions about work or frivolous spending
