Bought house for £209k in 2011 with about £65k mortgage when I separated from exH.
Now DH sold his house in 2017 when we were 47 and we paid off the mortgage. It was valued at £315k then.
We could have afforded to move somewhere bigger but we like the house and didn't really want the disruption just so his equity could be put into a house.
Instead, we invested the rest of the money from his house sale and started saving a reasonable amount as we could afford to.
It's now worth about £370k, which isn't very much compared to houses many people own by their mid 50s, but we're happy here. Now both my DS are at uni we don't need any more space, so are unlikely to move unless we want somewhere without stairs one day.
Sometimes I think it might have been sensible for us to move up the property ladder as we still live in what was my 'divorce house', which was the best I could afford at the time. The house from my previous marriage would be worth a lot more now.
But actually it suits us and we like having savings, which means we might be able to retire earlier than we would if we'd bought a bigger house. It's also cheaper to heat and council tax is lower than a bigger house would be, so no need to downsize to reduce running costs in retirement.
