I can remember when I could deduct all the interest from my credit cards....and it was a bundle.
RE: That state tax deduction is offset by the doubled standard deduction.
That’s only good for the low and reasonably taxed states ( Florida, Texas, New Hampshire, Washington, etc., states that do not have incomes taxes come out as winners ).
The losers are going to be the high tax states ( especially those with HIGH PROPERTY TAXES ). NY, NJ and CT come to mind.
