Tax benefits on interest on housing loans are allowable only for the original loan and for a second loan taken to repay the first loan and not for subsequent loans. This means that if you have already availed of one loan to refinance the original loan and want to now avail a third loan to refinance the second loan, tax rebate on interest payments will not be permissible. This is because the Section 24 (1) only talks of the second loan and not of subsequent loans. Even if you take the second loan at a rate of interest higher than the original loan, you will be eligible for a tax rebate on the second loan.
