When I was 26, I bought a flat. The Building society wanted 10% deposit, and would lend three times my salary of £10,000. So, my dad gave me the £3000 deposit, then three times £10,000 meant I could borrow £30,000. I got a place for £30,000.

Try that these days. Even a cheap house in Cardiff is at least £200,000. So you need a £20,000 deposit, then you need to be on £60,000 a year, to qualify for that three times your salary thing. Not very likely at a young age.
