You know it's not compulsory to buy a house as a first time buyer? Why not buy a flat, maisonette, shared ownership?
I agree the housing market is absolutely insane but it doesn't help when everyone thinks it's their right to buy a 4 bed semi as a first home. And I say that as someone who hasn't been able to afford to move to somewhere bigger for 25 years because I'm priced out of larger property.
We struggled to sell my mum's house at a very, very affordable price - easily affordable on minimum wage - because it wasn't a 3 bed semi and even the single people who viewed wanted something 3 times the size. So I get a bit cynical about the expectations of some FTBs.
