New public housing flats are strictly only eligible for purchase by Singaporean citizens. The housing schemes and grants available to finance the purchase of a flat are also only extended to households owned by Singaporeans, while permanent residents do not get any housing grants or subsidies from the Singaporean government and could only purchase resale flats from the secondary market at a market price. Such policies have helped Singapore reach a home-ownership rate of 91%, one of the highest in the world. In 2008, Singapore was lauded by the United Nations Habitat's "State of the World's Cities" report as the only slum-free city in the world.
