The Government is reviewing the Help to Buy housing scheme and could end or replace it before it is due to end in April 2021.
The Department for Communities and Local Government has asked the London School of Economics to evaluate the HTB scheme, according to Property Week.
The DCLG will also speak to the Home Builders Federation, housebuilders and charities as part of the review.
The department is investigating all options for the future of the Help to Buy scheme, according to reports.
The DCLG is considering a taper system, where homebuyers get reduced help as the scheme goes on, among other options.
