More than 5,000 housing association tenants have registered their interest in Right to Buy in one month, according to government figures.
Housing minister Brandon Lewis said the data proves the demand for home ownership as the government extends the controversial scheme to give all 1.3m social housing tenants the right to buy their own home.
“The government will do everything it can to help people buy a place of their own,” he said.
“There has already been huge interest in our Right to Buy extension, which forms part of our commitment to hard-working people.”
Local councils have raised concerns about the forced sale of expensive council homes to fund Right to Buy, saying it could halt new-build programmes where properties are valued above the given threshold.
In London, the threshold is £340,000 for a one-bedroom flat, £400,000 for a two-bedroom flat and £1.2m for a five-bedroom home.
Authorities have three years to replace properties sold under the scheme.
Right to Buy, Help to Buy and the new Help to Buy ISA will be available from 1 December.
The Help to Buy ISA will enable first-time buyers to boost their savings for a deposit on a house by 25%, with the government putting in £50 for every £200 saved, up to a maximum of £3,000.
