There is a wreck of house semi detached for sale with a 150 foot garden so huge scope to extend and plenty of outside space for the children. The house needs A LOT of work though, it needs considerable extending loft conversion and single storey. It has 3 bedrooms, one of which is tiny. West facing, you couldn't live in it whilst it was being renovated though (would mean moving in with parents).
A dated detached house is on sale for nearly £200k(!!) more which is at the very top of our budget - aside from decorating, any works would need to wait (i.e. knocking through the kitchen and dining room). It has 4 bedrooms though, so no loft conversion needed and already has an en suite. It ticks a lot of boxes as it won't need any extending (necessarily), south facing but the garden is a lot smaller than the first house. Both my kids love to play in the garden and kick a ball about. Would a smaller garden be a deal breaker with kids? It's not new build tiny by any stretch, the first house is 1930s and second is circa 1970s / 80s. The garden has been very well maintained by the current owners but I worry there's not enough outdoor space and it's smaller than what we are used to.....
Sorry for being waffley!!
