I know this topic comes up every so often, and I've read thru the previous threads, but as I was filling out TurboTax I could easily play the game with the payoff.
Here's the set of basic numbers from TT real estate taxes - $7,200 mortgage interest - $4,300
the overall itemized deduction is - $15,260 and our current refund happens to be - $3,953
if we had paid off the mortgage, the interest of $4,300 would not exist and the itemized deduction is now - $10,960 which is below the standard deduction - $11,400 adding the built-in real estate taxes of $1,000, and the standard deduction total is - $12,400 with the refund now reset to - $3,097
SO - the difference is $856 - is it worth it - ?
I guess the larger question, is the return on the total yearly P&I payment - $9,200 ?
Is that $856 / $9,200 = 9.3% ?
