The repayments towards a top-up on a home loan must be made on time. If you fail to make the payments, you will incur a late penalty fee of up to 2.00% per month over and above the prevailing home loan interest rate. You may also receive legal notice if you are unable to pay the EMIs over a period of time. It is advised to pick a loan amount and tenure that comfortably fits your budget to avoid late payments and hassles later.
