08M's Mortgage Deduction Cut is equavalent to is to 10%

increase in mortage for the highest bracket income earner. Before a $10,000 interest the actual payment for the highest braket was 6500, now it becomes 72000, a 7000 increase in payment, that's a whopping 10% more.

Am I right here, so that means a 5% mortage before now becomes 5.5%.
