If your primary intention is to have a minimum documentation and not the tax benefits, you better transfer the amount to your father for paying the loan installments and let the installments get deducted from his bank account. He will be eligible to get tax benefits.
Further, even if your father transfer the part of house property to you, you will not be able to take tax benefits because the loan taken for the purpose of BUYING/CONSTRUCTING a property will accompany the tax benefits. In this case you will not be buying the house property.
Please feel free to revert, in case you require any additional clarification on the above.
