Hello Dr. Jones, here is the solution in detail------------
As per Sec 24(b) of the Income Tax Act, 1961 , the simple rule of the deduction of interest is that whatever be the interest paid or due on loan borrowed for purchase, construction, repairs, renewal or reconstruction of house property is allowable as deduction. However, as far as self occupied house is concerned, the allowance of interest is limited to Rs 1,50,000 per owner. Also,You need not to show Interest on Loans taken for Construction & Repairs in separate ITR’s.
Secondly, the interest payable before you acquire home or start the construction work would be deductible in five equal annual installments commencing from the year in which the house has been acquired or constructed.
In case of self- occupied property, housing loan tax benefit is allowed only for one such self – occupied property.
The documents of registration of the property is the main document which reveals the share each co-owners has in the property. But if it is not specifically mention therein, a 'tenancy-in-common' is said to exist. All the co-owners can use the entire property and every co-owner is deemed to be having an equal share (50 : 50) in the property.
But interest is deductible only if the same is borrowed by co-owners i.e even if one is joint owner but not a borrower of the loan is not allowed any deduction of interest. Only the person borrowing the loan is allowed deduction.
Upon death of one of the co-owners, the interest in the house does not pass to the other co-owners but to the person named in the will of the deceased, who will then become a tenant-in-common with the surviving co-owners.
