What is the rule for top up loans?

The amount to be granted as top-up home loan differs from bank to bank. Moreover, the actual home loan amount and the new top-up loan amount should not be more than 70% - 80% of the value of the property. As the lender already assessed the creditworthiness of the borrower, availing a top-up loan is quite easy and quick. Also, in most cases, you don't have to furnish extra documents for approval. However, if more than 2-3 years have passed, your lender may ask you to refurbish a few documents (like income proof, bank statements and address proof).
