A You Gov survey has found that 37% of people currently living in London would put off having children until they could afford to buy a property.
Another 22% would not get married until they had their own home.
The survey was commissioned by the National Housing Federation and showed that 6% of people aged between 18 and 30 thought they would have to wait for 20 years before they could afford their own home in London.
Katy John from Pricedout.org.uk commented that 70% of new builds in the capital are bought as investments by landlords which is making it more difficult for first time buyers.
She says that the problem of affordability is compounded in London due to the general high prices.
