The boss of Harcourts says he's concerned a shared equity housing scheme could leave Government and the buyer with a whole lot of debt.

Harcourts CEO Chris Kennedy says it's a positive to them if more property's being sold.

But he says they have a responsibility that the people they sell property to, can afford it.

Kennedy told Mike Hosking they don't want people in ten years not having paid anything back - and actually being in a worse position if the value doesn't rise.

"At the end of the day, it's only the interest free part, I'm still having to pay down the equity, so it's just a question of the affordability."
