The 2013 Budget announced a new scheme, Help To Buy, aimed at boosting activity in the housing market. This measure may temporarily help boost confidence in the housing market, but there is a risk that, in the absence of an adequate supply response, the result would ultimately be mostly house price increases that would work against the aim of boosting access to housing. To mitigate this risk and engineer a supply response, the government should consider fiscal sincentives for holding land without development.
Of course housebuilders have these properties on their books as assets to offset their losses. if they are forced to sell and house prices fall so do the price of their assets and many volume housebuilders will go to the wall. Not necessarily a bad thing if the broken industry stricture is fixed.
