Also many don’t consider the impact of the higher standard deduction.

Only if your mortgage deduction combined with other allowed itemized deduction exceeds the standard deduction, do you actually get any tax benefit. You should be counting only the itemized deduction exceeding the standard deduction and prorating across all itemized deductions to get the true tax savings you realized.

And the entire real estate obfuscates this point. Every one of their online calculators show the full benefit of the mortgage interest itemized deduction.
