The South Australian government has announced the completion of the sale of the 100 new and affordable homes built specifically for low-and-moderate income South Australians.

The homes were part of the state government's $21.4m commitment to boost the supply of homes in the state. The dwellings, 71 of which are affordable ones, were sold from as little as $250,000, up to $418,000. Michelle Lesink, minister for human services, said first-home buyers had snapped up the homes.

"Our strong plan to increase the supply of affordable housing in South Australia is hitting the mark when it comes to helping people on lower-and-moderate incomes get into homeownership as well as supporting vital jobs during the COVID-19 pandemic," she said.

Lesink said the 71 affordable homes has given many South Australians the opportunity to buy homes in suburbs close to the CBD.

“It’s great news because it means people on moderate incomes have been able to purchase a home much closer to the city than they would otherwise be able to and there’s the added bonus of not having to compete with investors or the broader market at auctions," she said.

With the 100 homes stimulus now complete, the state government has already commenced its $400m initiative to deliver 1,000 homes to by 2025.

“Our $400m commitment to deliver 1000 new affordable homes is creating a steady pipeline of work for our building and construction industry, guaranteeing jobs and certainty for hundreds of tradespeople and their families for the next five years,” Lesink said.
