Most people do not believe that homes costing £250,000 should qualify as ‘affordable’.

The £250,000 price tag – or £450,000 in London – was cited by David Cameron last month.

In a speech to the Conservative party conference, he pledged to build 200,000 starter homes.

The Government’s Housing and Planning Bill, currently going through Parliament, proposes that the affordable new starter housing should be capped at £250,000 outside London and £450,000 in the capital.

But new research among 500 adults, carried out by Gorkana for conveyancing firm myhomemove, found that 66% thought that ‘affordable’ should mean homes costing under £120,000.

Even in London, the majority felt that to be called ‘affordable’, homes should cost under £160,000 – with the largest number saying that ‘affordable’ homes should be under £100,000.

The 500 who took part in the survey covered all regions and all ages.

In all but one age group – those between 18 and 24 – the strongest opinion was that ‘affordable’ should mean homes costing under £100,000. The youngest age group mostly plumped for ‘affordable’ meaning homes priced between £100,000 and £120,000.

Doug Crawford, CEO of myhomemove, said: “While we welcome initiatives designed to increase housing stock numbers, our research shows that these homes are far too expensive for the majority of the population to consider affordable.

“Last month, our own data showed that one in 20 homes are bought using a gifted deposit.

“So, even with an accelerated building programme to ease the shortage issue, unless these properties are capped at a much lower rate, very few families will be able to afford these ‘affodable’ homes.”
