Thanks for the quick reply! So if I’m understanding this correctly, I will add the original purchase cost of the 864 sq ft home bought in 2014 plus the new garage addition, new roof and new septic from 2018 plus the new windows from 2023 plus the cost to have the new 336 sq ft added on for the apartment along with its new well, furnace and central air. Then I will say that 40% is used for business (Total house including the apartment is 1200 sq ft. The apartment is 480 sq ft which includes the bedroom that used to be part of the main house). Does that sound correct?
