Lets not get too excited and look at the article.
"11 per cent of mortgage holders would be unable to meet repayments if hit with a £100 rise" - I would say that £100 pm would affect the majority of people, being £1,200 pa (or the equivalent of £2000 pa pre tax).
However lets look further down the page.....
"The increases amount to around £50 a month on a £200,000 mortgage" - ok it's not a bad as the headline would leave you to believe. On this basis the "£100 per month increase" would only affect those with a £400k mortgage. Hmm, makes you think.
Extrapolated figures always give misleading information.
