@Moier how did you manage to gift such huge sums? Did you win a lottery?
my grandparents lived in a council house, but my mum (a teacher and single parent, dad died aged 39) was careful with money and a large house she used to make money by renting rooms etc when I grew up.
she regularly topped up my monthly salary when I was early 20s and she saw I needed it, she gave me £5k when I got married and £80k when she inherited some she didn’t need. She gave me £25k from some shares she sold when my kids were babies and I had about £400k from her estate when she died.
my kids had £6k at 18 and will inherit £90k from her estate when they reach 25.
that’s it though - no more coming from anywhere. I’ve bought a property with her inheritance so that’s my pension, and her gifts have made me very privileged which I’m so grateful for - although we have a simple life and shop in Aldi we travel a lot and don’t struggle to pay bills.
despite my kids getting what some will think is a huge amount at 25 I suspect their lives will not be easy as mine, although my brother has a huge house and no kids, so I suspect they’ll benefit from that.
to answer your question, my experience is that many people do get funding from family, but I suspect geography comes into it - many of those in the south east have a lot of cash available compared to elsewhere.
