## Summary

This video explains how credit scores affect mortgage interest rates and monthly payments, using a specific example comparing a 760 and 680 credit score. It then provides three actionable tips to improve your credit score before applying for a mortgage.

### Key Points

- **Interest Rate Difference by Credit Score** [00:02] — At a 760 credit score, the interest rate is roughly 6.5%, resulting in a monthly payment of about $2,528 per $510,000 loan. With a 680 credit score, the rate jumps to 7.5%, and the monthly payment increases to $2,797.
- **Long-Term Cost Impact** [00:14] — The $270 difference per month adds up to approximately $97,000 more in total interest over 30 years, totaling $607,000 in interest for the lower credit score scenario.
- **Tip 1: Keep Credit Utilization Under 10%** [00:31] — Keep your credit utilization below 10% (e.g., if your available credit is $10,000, carry less than $1,000 balance). This can improve your score by 20 to 40 points compared to the 30% threshold.
- **Tip 2: Become an Authorized User** [00:57] — Becoming an authorized user on someone else's card with a good payment history and high credit limit can boost your score, as their positive history is attached to your credit report.
- **Tip 3: Check and Dispute Credit Report Errors** [01:00] — Review your credit report for small negative impacts and dispute them to potentially increase your score.

### Conclusion
