The only way we'd be able to afford a house is by a miracle or someone leaving us money.
My husband and I grew up and live in and expensive area (2 bed flat is just under £200,000 and rent for most 2 bed flats places here is around 900pcm). He's built his business here, it's where his clients are and moving hundred of miles away to somewhere like to North or Wales where its cheaper just isn't an option for us.
It is annoying but we just have to keep trying to save but we have our two girls and love them and if renting is what allows us to give them a roof over there heads then we like that. It's hard though when we see "affordable" housing being built nearby then find out straying prices are £300,000 - £500,000 and that those aged 60+ are buying houses with 4+ bedrooms becuase apparently they still need a bedroom each for their children.
My parents won't be able to leave us anything but they've also never given us things like cars. Always said we had to earn them ourselves.
My in laws are divorced, Mil owns her house, but that will probably be left to her husband who'll in turn leave it to his children. If Mil did leave it to someone else I doubt DH would get a look in as she cares more about sil and her son.
DH nan (98) is now in a home so that will use up her money.
I don't worry though. My neighbours growing up were old and one of them rented the house they lived in for most of their life, never bought. They said the money they saved they could give to their children and that they didn't have to fuss with selling a house when they were gone.
