Always pay your dues on time
Late payments are viewed negatively by lenders
Keep your balances low
Always prudent to not use too much credit, control your utilization
Maintain a healthy mix of credit
It is better to have a healthy mix of secured (such as home loan, auto loan) and unsecured loans (such as personal loan, credit cards). Too many unsecured loans may be viewed negatively.
Apply for new credit in moderation
You don’t want to seem Credit Hungry; apply for new credit cautiously

In co-signed, guaranteed or jointly held accounts, you are held equally liable for missed payments. Your joint holder’s (or the guaranteed individual) negligence could affect your ability to access credit when you need it
Review you credit history frequently throughout the year
Purchase your CIR from time to time to avoid unpleasant surprises in the form of a rejected loan application
