Deductions & credits

I am reviewing the reply since I have similar situation.

I sold my main house in Nov 2022 which was purchased in April 2017 , and purchased my new house in Aug 2022. 

I have 3 1098 forms, 2 for the sold house and 1 for the new house as I did refinance for the sold house in 2022.

The loan for old house was $900k(less than $1M), the load for new house is $1.5M.

 

How should I calculate the balance and the interest amount can be deducted?

Can I deduct all for $900k for Jan - Nov, then calculate interest for $750k of $1.5M for Dec?

 

Thank you!
