To apply for a Pag-IBIG loan, you need to be an active member and have made at least 24 monthly contributions. Required documents typically include a loan application form, proof of income, and any identification documents. You can apply directly at a Pag-IBIG branch or through their online services. It's essential to check the official Pag-IBIG Fund website for any specific requirements based on the type of loan you need, as these can vary. Always consider consulting with a Pag-IBIG representative for personalised assistance.
