Average house prices in the UK were 6 times the average wage in 2001 and 9 times the average wage in 2011, whilst in 2008 lending rules were dramatically tightened meaning larger deposits are required and higher multiples of salary cannot be lent.
Private renting became less secure when the 1988 Housing Act removed a lot of controls on landlords, and social housing stock has been declining since Right To Buy began in 1980 and the Local Govt and Housing Act in 1989, pushing people into private rentals.
From the study I linked to earlier:
" The average house price for those who were first time buyers increased by about 96% between 2001 and 2011. This meant larger deposits which are linked to the house price, were required.
Tighter lending requirements, especially in the wake of the recent recession meant a larger percentage of the house value was required as a deposit, as the era of near 100% mortgages became a thing of the past.
Declining wage growth and rising inflation over the period exerted pressure on household spending and eroded the value of savings. While in 2001 the average house price in England and Wales was six times the average gross wage, by 2011 the average house price was nine times larger than the average wage. This meant households needed to save for a longer period in order to provide a deposit.
The fall in people buying their homes and the subsequent rise in people privately renting has seen schemes such as ‘Buy-to-Let’ flourish over the decade. "
So the poster claiming you can actually buy more for a typical wage now is just, simply, objectively, totally wrong.
