From single parents to families and the elderly: These are the winners and losers in this year's budget cash splash from the government. The scheme — which will be available to 10,000 single parents over the next four years — is not restricted to first home buyers, but is subject to the individual’s ability to pay back the loan. Single parents who earn up to $125,000 a year are eligible. You can apply for the guarantee, previously known as the First Home Loan Deposit Scheme, via your bank. The scheme allows prospective buyers to put an extra $15,000 into their super each year.
