Thank you all, each comment was useful and interesting. The push & pull factors are quite similar in many examples and I think in our case some issues would have likely triggered a move, if we had nightmare neighbours etc. Our neighbours are lovely and I appreciate how important that is. The crime incidences were close to being a push factor but on balance, we figured the issues were no less likely elsewhere.
It really suited when the kids were young, near family, beside a park etc, and in a way it would be madness to move further away from aging parents now.
I'm in Ireland so the market is different. For a while we were in negative equity which meant no chance of a move though thankfully that has changed in recent years but I'm keenly aware of ceiling prices as some of you mentioned, we've done enough now to this property, we'd hopefully recoup our investments but I wouldn't extend further.
There is little scope for character property where I am, it's mostly new builds or rarely, very high cost period property and as I mentioned it's a developing area which will eventually be incredibly built up. Id love a bit more space to breath. The flip side is that we are easily commutable to a city for Uni/work etc for the kids in a few short years.
I just think after 15+ years I'm bored of the area and would love a new environment but of course it's not that easy and the costs to move are huge.
I feel we may have missed the boat as our kids are now tweens/young teen and the best chance may have been before the eldest started secondary, the younger two start this Sept so I suppose that has brought up the 'maybe we could move before then' vibe again.
I think it's also partly mid life crisis feelings - is this it? Then I feel bad because were lucky in many ways.
DH thinks the next move should be more of a rural one, in a different part of the country which would tick some dream boxes - by the sea etc - but is also impractical for the kids in the coming few years.
Someone mentioned their move being brave and I think that's what I envy - that leap into a new adventure. It shouldn't be such a huge deal to move but I fear I've made it one!
