The government is expected to allow households earning up to £110,000, or £140,000 in London, to apply for its Your First Home scheme, according to reports first published by The Times.
The scheme will offer government-backed equity loans worth 20% of new-build properties bought from participating developers, with an initial interest-free period and deposits from as low as 2.5%. It is designed to help first-time buyers in England.
Speaking at last month's Labour conference, Prime Minister Andy Burnham said the scheme would focus on those who "really need support". The Times reported that ministers initially planned earnings limits of £90,000 outside London and £110,000 in the capital, before deciding those figures would exclude too many middle-earning couples, such as teachers and nurses.
Details of the salary caps are due to be confirmed at next week's Budget. The government has said the scheme will help boost housebuilding after ministers conceded they are set to miss a target to build 1.5 million homes in England by the next election.
The scheme resembles the coalition government's Help to Buy programme, which ran from 2013 to 2021 and offered 20% shared equity loans, interest-free for the first five years, on new homes worth up to £600,000 with 5% deposits. A second version, running from 2021 to 2023, was restricted to first-time buyers with regional price caps. Previous Help to Buy-style schemes did not restrict eligibility by income and were criticised for stoking house prices by letting relatively wealthy households borrow more.
Labour says Your First Home will be funded within existing government budgets, but has not said which areas will face spending cuts. Participating developers will be asked to contribute towards running costs.
