Query in this case - "I can claim interest paid before possession year in five equal installments starting from possession year. Say, I paid 1 lakh interest before 2013-14, then I can add 20,000 interest claim into 2013-14 claim and similarly for next four years." Suppose i am claiming 1,50,000 of interest of home loan, does it mean the 20000 amount i will claim will be apart from this 150000 making total tax free to 150000+20000? or 150000 is the upper cap which includes 20000?
