Interest on mortgage in excess of 750K can be set off against interest income?

Hi,

If the mortgage is say 1 million (excess of 750K), then only the interest on 750K is deductible from taxable income. Say  have interest income from high yield savings account and mortgage of 1 million,  can the interest earned through savings account be set off against the interest paid for mortgage amount in excess of 750K ?
