Type of loan for interest deduction- commercial property construction -

I dont know why bank is not giving you loan on commercial property it fetches more revenue to banks which you can claim deduction under 24 but if you mortgage some other property and got mortgage loan you cannot  claim deduction under 24 against commercial property 

I think you should take the deduction benefit u/s 24b.

Point has been mention below:-

1) You are not acting with act to avoice income tax because honestly you have taken the loan for let out house property.

2) You have to talk this matter with AO if your return is called for scrutiny u/s 143(2). Other wise nothing happen.

But the construction of house must be completed within 5years from the FY when loan was taken also you must be keep all documents.
