When I left college I looked for jobs all over the country, the ones in London were on the other side so I'd still have lived away (but near enough to go 'home' at weekends, so felt that I wouldn't have a real life at either place). So I moved 200m north.
I had expected that my children would also move away, but it seems to take longer now to get a 'graduate job' - there were fewer of us, so we had firms sending recruiters round, offering good money in our final year.
I was glad that my young daughter and partner moved in with me after college, as it had been a very empty nest in term time, with my husband and myself taking turns to spend 2 weeks at the other side of the country looking after his mother (just meeting in passing)
When we decided, 3 years on, that it was time to move her over to us, they quickly found a house to buy (there would have been room for us all - at a squeeze).
