The housing market is broken. Ds2 is working full time. Has more than a 10% deposit, but can't buy anything because 5x his salary will only buy half a house here. He's earning above minimum wage as well.
He could get a shared ownership where the price is overinflated and the cost of the rent on top of the mortgage would cripple him, and be more than a larger mortgage on a house he owns only with the bank.
I don't envy whoever tries to fix it. Prices have to come down to a normal level.
