The average home in Kensington and Chelsea requires a £303,000 salary
First-time buyers in London must earn £93,000-a-year to afford an average home in the city, a report has claimed.
The research by the National Housing Federation, which represents 1,200 housing associations, puts the average house price in London at £362,000.
A single buyer would require the near-six-figure income to get a 90% mortgage at 3.5 times their salary.
The average wage in London is £26,000, while overcrowding rates are 2.5 times the national rate, the report said.
The Housing Federation's Belinda Porich said: "Even by London standards, these are astronomical prices and many people - especially young, first time buyers - can only dream of owning a home.

"Providing more affordable housing is part of the solution - everyone has a right to a home."
The report claims 353,000 families are currently on social housing waiting lists, while more families became homeless last year than new homes were built.
Nearly 7% of houses in London are overcrowded, the authors added.
Ms Porich continued: "This modern-day scourge of overcrowding affects the black community in particular.
"Overcrowding and the huge waiting lists show that governments must recognise the urgency of building new affordable housing."
