The Government's Help To Buy scheme will have the reverse effect from what it set out to do and make home ownership less accessible by driving up prices, a think tank has warned.
The Adam Smith Institute said Help To Buy will simply increase demand for houses without a similar increase in supply, therefore driving up house prices.
Those on the scheme will benefit from the extra leg-up, while those not on the scheme will be left behind, they said.
The Institute's research director Sam Bowman said: "It is crazy for the government to stoke demand even more without addressing supply and claim that this will help the housing market.
"Making taxpayer-subsidised handouts to homebuyers will only drive further house prices up, risking a bubble, improving access for a select few but making housing even more unaffordable for most people.
