Case Study: $20,000 in Interest Saved — The Power of a 700+ Middle Credit Score®

When Tyler Nguyen, a 29-year-old software engineer in Denver, Colorado, began shopping for his first home, he had a Middle Credit Score® of 682. Though this was a respectable score, Tyler knew that crossing the 700 threshold could unlock better mortgage rates, which could lead to significant savings over time. His goal was to purchase a $410,000 condo in the city’s Central Park neighborhood with 10% down and avoid unnecessary interest.

After receiving an initial interest rate offer of 6.625% based on his current score, Tyler ran the numbers and realized the total interest over 30 years would exceed $502,000. But if he could raise his score just 18 points and qualify for a 6.125% or lower rate, his total interest could drop by over $20,000.

That was all the motivation he needed.

Tyler’s Strategy for Breaking 700

• Targeted Paydowns: Tyler had two credit cards. One had a $7,000 limit with a $2,800 balance (40% utilization), and the other had a $5,000 limit with a $1,600 balance. He used $2,000 from a signing bonus to reduce both balances to under 10% utilization.
• Increased Limit Request: Simultaneously, Tyler requested credit limit increases on both cards. One issuer increased his limit from $5,000 to $8,500, further reducing his utilization percentage and improving his score.
• Review and Dispute: After pulling his credit reports from all three bureaus, he found a closed credit card from college still listed as having a balance. He disputed the item and had it corrected within 10 days.
• Goodwill Adjustment: Tyler had a late payment from 2021 on an auto loan. He contacted the lender, explained the situation (a banking error while switching checking accounts), and they agreed to remove the late notation.
• Authorized User Boost: Tyler’s brother added him as an authorized user to his long-standing credit card account, which added 12 years of history to Tyler’s credit file.
• Rapid Rescore Request: Once all updates were confirmed, Tyler worked with his lender to initiate a rapid rescore process before locking in a rate.

Post-Closing Reflections

After closing, Tyler immediately began working on an emergency savings fund using the extra monthly savings. He also automated additional principal payments to his mortgage to accelerate equity growth. Within six months, Tyler had reduced his balance enough to request a PMI removal review.

He also encouraged coworkers to run mock mortgage comparisons using their credit tiers—turning what most viewed as “just a number” into an actionable financial advantage.
