Deductions & credits

Thanks for the reply, but I am not sure i understand fully the reply. I have 2 loans:

Loan1: Previous Primary -> Investment property mid-year

Loan2: New loan for primary house mid-year -> refinance

 

Are you saying that it is enough to say that my 2nd loan (for the new primary house) is 0? Can you explain why this is what IRS expects from me to write?
