Mayoral election: London's housing crisis
For many Londoners, the high cost of homes, the limited availability of mortgages and low or insecure incomes put home ownership, even that offered through low cost schemes, out of reach.
But just how difficult is it to get on the property ladder?
In London, average houses prices are 51% higher while private rents are 64% higher than the rest of England according to the Greater London Authority (GLA).
The GLA also says first time buyers are paying an average deposit of 28%, about £97,000.
So with the capital's population set to rise from 7.6 million to nearly 9 million by 2031, will there be enough homes for everyone?
Currently London's mayor has to work with organisations to bring together funding, land and permission to build homes.
However from May the rules change when the entire housing budget and over 500 hectares (1.2m acres) of public land transfers to the GLA.'Bitter pill'
One of the main problems is the number of households is predicted to grow due to later marriages, fewer children, divorce and longer lives.
Of the 750,000 to 850,000 additional households that London will need by 2031, almost 75% will be single person households, according to London's Housing Strategy.
Russ Tams, 30, works in post production and rents a two bedroom flat for £1,300 per month in east London.
He said he has given up trying to buy as it was too difficult to get a mortgage.
"All my friends in the north are buying houses so it's a bitter pill to swallow. I can't do my job anywhere else so I need help. It should be a little easier to get on the housing ladder," he said.
"We need to look at the renting market and make some more social rather than build new builds."'Locked out'
Housing charity Shelter has launched a campaign ahead of the mayoral election to push for as much emphasis on housing as there has been on transport.
Shelter's chief executive, Campbell Robb, said: "Decades of failure to build enough affordable housing has left huge swathes of Londoners locked out of home ownership, pushed into a revolving door of private let after private let."

- Around 400,000 children spend each year in overcrowded accommodation (Shelter).

- Rental prices have increased by 26% over the last few years but from November to February 2012, they have decreased by 0.2% (ARLA)
- The number of homes now being rented as owners cannot sell them has increased 18% in one year (ARLA)
- Some 49,640 homes were built in Ken Livingstone's second term
- Since Boris Johnson was elected 40,910 have been built, but it is estimated to be 57,111 by end of his full term
Tim Hyatt, president of the Association of Residential Letting Agents (ARLA) and head of lettings for estate agents Knight Frank, said there was a core shortage for prime central London properties being offered for rent for between £200 and £750 per week.
He said although the market was always busy, the demand was still exceeding supply and getting progressively worse.
Mr Hyatt believes rents will increase by between 5% to 10% in the next year, however some areas may have higher increases.
For example, rent for a one bedroom property in Highbury, north London, is 10% more than this time last year, while rent for a property in Knightsbridge, west London, has decreased as the "demand from mid to senior management is not there anymore," he said.
"Properties for a young first time renter is where the demand is," he added.'Too few people'
Mr Hyatt said more could be done to free up housing stock because otherwise rents would increase further which would have the impact of people not being able to rent or buy.
However Mr Tams said he was "fed up of hearing" of the need to build more houses as little were available because "too few people own too many properties".
Mr Hyatt said developers had to sell the properties as quickly as possible so they have enough money to build the next project.
This may mean that developers choose to sell 20 properties to a single owner with a 20% discount rather than to individuals.
