The CIBIL score is determined by your credit history and repayment history. You can check your CIBIL score by going to the CIBIL website and following the instructions. The score ranges from 300 to 900, with 750 or higher considered favourable for home loan applications. Your credit history, outstanding debts, repayment behaviour, credit utilisation, and credit inquiries all have an impact on your score. Maintaining a good credit history and paying your bills on time can help you improve your CIBIL score over time.
