Since the limit on deductible interest is $750,000 loan balance, you can deduct roughly 66.3% of your interest payments ($750,000÷$1,123,000).  The exact percentage will be calculated based on your average mortgage balance for the year (since your balance on December 31 will be slightly less than your balance when you took out the loan, due to making payments).
