The objective is to focus on construction of unfinished units, it said.

In addition to the government's contribution of Rs 10,000 crore to the fund, roughly the same amount will be sourced from external investors. The fund will be managed by professionals, the Finance Minister added.

The Finance Minister said the government would relax external commercial borrowing (ECB) guidelines to help housing developers obtain overseas funds.

Ms Sitharaman also said the interest rate on housing building advance will be lowered and linked to the 10-year government securities (G-Sec) yields.

"Government servants contribute to a major component of demand for houses. This will encourage more government servants to buy new houses," she said.

The Finance Minister also announced a slew of measures to boost exports, including a new scheme to incentivise exporters, called the Remission of Duties or Taxes on Export Product (RoDTEP).

The scheme will come into effect from January 2020 to replace existing dispensations including the Merchandise Exports from India Scheme (MEIS), which will continue till December 31, and "will more than adequately incentivise exporters than existing schemes all put together", Ms Sitharaman said.

The estimated amount of revenue that the government will forego on the scheme is Rs 50,000 crore, according to the official statement.
