Housing charity Shelter has called for action to tackle a "desperate shortage" of affordable homes.
In the South West, only six in every 100 homes in the South West are affordable. Shelter chief executive Campbell Robb said:
When the number of affordable properties in an entire town can be counted on your fingers, it's not difficult to see why a stable home of their own is quickly becoming a distant dream for the next generation.
It's right that young people who aspire to own their own home should work hard and save each month, but with such a pitiful number of affordable homes on offer - even with a generous 20% deposit - our housing shortage is holding them back.
Unless we build the affordable homes we desperately need, house prices will continue to rise and as a result more people will be forced to live at home with their parents into their thirties, or move into the expensive and unstable private rental market.
Young people are working hard and doing their bit. Now the government has to meet people halfway and increase the supply of affordable homes - not the supply of credit - or the prospect of a home of their own will slip even further out of reach for future generations.
