Deductions & credits

Hi again, 

Thank you so much for your time again.

Yes my father married her in 2013. So, I understand her cost basis will be different from my brother and I. 

I am working on finding the fair market value of the house in 2013. I just have to figure out the math or respond to the questions with whole numbers or just the 1/4 or 1/3 portion that is mine. 

thank you again.
