thanks for your reply!
No it is different for several reasons - that calculation is to determine the average mortgage balance, I already have that value - what I need to understand is how to calculate the mortgage interest that is deductible. Also, it assumes I owned the home the entire year, and I didn't. I am sure I am not the only one that has seen this but pub 960 is not useful for this situation
For some odd reason turbotax has now reduced the amount even more so giving me the standard deduction. Of the 18300 paid in mortgage interest I have 3 different values:
1. Turbo tax at about 8400
2. Average mortgages which then all 18300 is deductible, and saves me significant $$
3. Average the mortgage interest and calculate based on the ratio each month, about 15000 is deductible
