A 10% hike to mortgage payments would sink almost 3 quarters of homeowners, Manulife says

``Fourteen per cent of respondents to Manulife's survey said they wouldn't be able to withstand any increase in their monthly payments, while 38 per cent of those polled said they could withstand a payment hike of between one and five per cent before having difficulty. An additional 20 per cent said they could stomach a hike of between six and 10 per cent before feeling the pinch.''
