Housing Justice has been speaking as fresh analysis found the proportion of households were own their home has fallen to a 30-year low, with soaring prices and high rental costs partly to blame.
The Resolution Foundation think-tank concluded every part of the UK has seen levels of home ownership plummet since peaking in the early 2000s.
Speaking about opportunities for families who rent to buy their own homes, chief executive Alison Gelder from Housing Justice added: "It is almost impossible, especially once you have children.
"All your money is straight out of the door at the beginning of the month and people really struggle to save for anything, whether it's a pension, holiday or a home."
House ownership rates in England fallen by seven per cent to 63.8 per cent from 70.8 per cent in April 2003, while the UK-wide figure has fallen by 6.8 per cent since peaking at 70.9 per cent in October 2004.
The biggest regional fall which seen in Greater Manchester (a 14.5 per cent drop since April 2003 to 57.9 per cent, from 72.4 per cent), followed by Outer London (a 13.5 per cent fall to 57.8 per cent from 71.4 per cent in October 2000).
The West Midlands came third in the list, with a decline measuring 11.2 per cent, compared to a high in April 2005 of 70.5 per cent.
Stephen Clarke, policy analyst at the Resolution Foundation, said: "These drops are more than a simple source of frustration for the millions of people who aspire to own their home.
"The shift to renting privately can reduce current living standards and future wealth, with implications for individuals and the state."
Alison Gelder from Housing Justice added: "It is a problem for government but all of us need to think about how can we increase the supply of affordable homes.
"That means using the homes we have got better. Maybe if we've got a spare room [this could mean] taking in a lodger."
Director of Church Housing Trust, Miriam Morris, told Premier's News Hour the problem is that homes are no longer just somewhere to live.
She said: "Homes have become investment products, they're just commodities, so that means that people that want somewhere live are now competing with investors.
"We've got people buying to let, buying to leave and buying second homes because savings interest rates are very low and pensions are very unstable."
"It's very disappointing, especially in the light of successive governments wanting to increase home ownership, I think the real issue though is people not having homes, not having secure and affordable places to live, whether they own them or rent them."
