Hi OP, We moved into rented for a couple of years then sold and bought, I have absolutely no regrets, moving was a no brainier, dh works long hours so being an Uber away when he’s not travelling is and has been brilliant. Mind you we didn’t move out out of london, it was far enough and I was only pregnant with dc1 when we moved but would have done it with dc. I’m guessing your dc are young enough to move? once in secondary, moving imho would be much harder.
From that experience, I will always choose location over property, I’d rather live in a smaller property in the right location than a larger property in the wrong location.
If we moved out out of london I knew that my dh would be miserable and beaten doing the daily commute and never really enjoying the big house as would I being stuck in a big house with dc, constant maintenance and nowhere to go!! (without car etc)
We’ve had many friends move out of london over the years we have visited so get the gist of their new lifestyles.
Anyway there’s some really positive advise on this thread for you, from what you write I get the sense the move to Surrey was the catalyst of your mental health deteriorating, it wasn’t the white picket fence dream you thought it would be when having your family. It usually takes 2 years to settle anywhere new, if time hasn’t helped you settle in Surrey then maybe the move can only be a good thing. It’s ok it didn’t work out, important thing now is how to make it better. Moving (anywhere) can be stressful, but if you think it will be helpful in the long run then it’s worth it.
You sound like a strong resilient person and change is possible, in fact at your fingertips if you want it. Only you can decide, what does your DH want? Maybe take some time to properly research and plan the move. If you are renting then you have the choice to move into catchment if the first school place is no longer available.
It’s totally understandable to wobble you might make the wrong decision again, its a big one but if your only other option is to go on AD’s (that may not work) to tolerate a life in Surrey that is making you miserable then i agree with what @longwhiskers14 said “if you don’t at least try it, you’ll make yourself more miserable wondering “what if”
I hope that helps, good luck with everything.
@JoJoSM2 other than polluted and pokey, wise words, your post applies to both scenarios London or Surrey. ;)
