    Loan1 is 2021 and second is 2024.

    For now I did my own calculations. I added 11 month of interest for 1st loans. Used 750k/765K * interest of 11 months.

    For last month I captured interest of 12th month. Second loan was started in November month of 2024 . It had higher interest for December month. So I used 750/1240 * December month.  This gave me total of around 22k.

    Turbo tax was calculating incorrectly. It was taking average balance from second loan which was about 1239000. This was reducing my interest to 10.3k. I adjusted it to 22K based on above calculations

     

     I hope this calculations is right.

    No, you're not doing it right. If the balances you provided were the actual average balances, your interest deduction would be approximately 750K / (765K +1240) * (21K + 6K) = 10.1K. So it seems TT is doing it correctly.

    PUB 936 speaks to average balance but without clearly defining how to compute the average when a loan is taken out during the year.  I think an acceptable method would be for the first home to average the balance at the beginning and end of the year by totaling those amounts and dividing by 2.

    for the second house, take the beginning balance and the year-end balance and divide by 2

    multiply this by the number of months you paid interest in 2024 and divide by 12

     

     

     

    divide 750 by the sum of the two average balances and multiply the total interest paid

     

    so you might have something like this'

    average balance 1st house 750K average balance second house $100K because it was taken out late in the year

     

     

    deductible interest would be 750 /(750+100)* 27

    Pub 936 is intended to provide guidance on applying the tax code to the mortgage interest deduction. It provides some of the acceptable methods of calculating the average mortgage balance and applying the deduction limit. Pub 936 does not, however, address the situation where a taxpayer sells their main home and buys another. These taxpayers are stuck with the instructions in Pub 936 that apply for taxpayers with both a Main and Second Home which are generally unfavorable if you sold one home and bought another. However, Pub 936 is not absolute and any reasonable alternative method of applying the mortgage limit may be used.

     

    @lvikiYour method is not reasonable because you are applying the $750 limit to each mortgage individually which exceeds the limit. @Mike9241 Your method is reasonable in my opinion but you can't overlap the monthly balances. This is because you can only deduct the interest paid while the home is a qualified home and only one home can qualify as the main home at any one point during the year. Home1 was the qualified main home up to moving into Home2, lets say Dec 2024, when it became the qualified main home.

     

    I believe it is reasonable to sum up the monthly balances of Mortgage1 for Jan through Nov with the Dec monthly balance for Mortgage2 and dividing by 12 to get your average mortgage balance. Then divide 750K by this average balance to get the % interest deductible. Only sum up the interest paid for Mortgage1 Jan through Nov with the interest paid for Mortgage2 in Dec and multiply by the %.

    Let me shares results running all three methods discussed here. Taking sample on below data

    Home1 average balance - 765k

    Home1 total interest for 12 months - 21000 

    Home1 11 months interest - 19500

    Home2 average balance -1240k

    Home2 December interest - 6000

     

     

     

    My method - 

    11 months average balance calculation with Loan1. - 

    (750/765) * 19500 = 19117

    1 month average balance calculation with loan2-

    (750/1240)* 6000 = 3629

    Claimable interest= 22746

     

    Zoombo method - let's consider hypothetically that Jan to 11 months sum is 765* 11 = 8415

    Dec month avg balance = 1240

    Sum of above 2 = 9655

    Avg balance= 9655k/12 = 851k 

    Total interest = 19500+ 6000 i.e. 25500

    Claimable interest = (750/851) * 25500 = 22473

     

    Mike9241 method - 

    I paid loan1 for all 12 months. So avg balance for Loan1 will be 765k

    For loan2- ( 1 month * 1240k )/12 = 103

    Total avg balance = 765 + 103 = 868

    Total interest considering overlap month= 27k

     

    Claimable interest = (750/ 868) * 27000= 23329

     

    Claimable interest ( non overlapping month) = (750/868)* 25500 = 22033

     

     

     

    In all 3 methods Mike non overlapping method give best results.

     

     

    @zomboo- My and your methods are very close. I am considering each loans individually for the duration I am using interest on that month. It does not exceed 750 as I count interest only for that duration. 

     

    For e.g. let's take simple example. if my first loan avg balance was 750 for 10 months and let's say I closed it in October.. interest let's say 20k for this loans. I can claim all 20k as it was under 750k

     

    Now I take second loan of 1500k and pay interest of 10k. I can claim 750/1500 * 10= 5k

    Total 25 k

     

    Your method = ( 750*10 + ( 1500 +1499) )/ 12 = 312

    Total balance as per your method= 750+312= 1063

    Claimable= (750/1062) * 3000 = 21186.

    21186 is totally wrong here

     

    I hope above example makes it clearer why method is better and more accurate. 

     

    I am also inclined towards overlapping method of Mike as it seems reasonable as I paid overlapping interest. I feel it needs some tweaking though to get the accurate results.
