AD Mortgage Credit Score Study Reveals Interesting Facts

AD Mortgage, a wholesale lender, has released a comprehensive nationwide credit score study, Credit Score vs. Mortgage Cost: How Long It Takes to Improve and How Much It Can Save, State by State, revealing how credit readiness directly impacts homebuying affordability across the United States.

The analysis demonstrates that even modest improvements in a borrower’s FICO score can translate into tens of thousands of dollars in mortgage interest savings over the life of a 30-year loan. While the 760-credit score threshold for securing the most competitive mortgage rates remains consistent nationwide, the financial impact of reaching that level varies significantly by region.

Among the most notable findings is the variation in savings between states with higher home prices and those where borrowers face steeper proportional rate penalties. In California, borrowers who improve their credit score to 760 can save approximately $42,753 over the life of a loan. In Texas, borrowers can save approximately $26,881, but face one of the highest proportional penalties for sub-760 scores, with having a cost of more than 10.7% of the total loan amount.

Key Findings From the Report:

• Borrowers nationwide can save between $10,000 and $46,000 in mortgage interest by improving their credit score to 760, depending on the state.
• Hawaii, California, and Massachusetts rank among the states with the highest absolute dollar savings, driven largely by higher median home values.
• Alabama, Mississippi, Georgia, Louisiana, and Texas show some of the steepest rate penalties for borrowers below 760, meaning interest savings can exceed 10% of the total loan amount once top-tier credit is achieved.
• In most states, improving an average FICO score to 760 takes between 1.5 and 3 years, though it can take longer in states with lower average credit profiles.
• When measured against local household income, the affordability impact becomes even more pronounced. In higher-cost states such as Hawaii and California, savings from achieving a 760 score can exceed 40% of annual household income.
  

The findings highlight how credit score gaps influence purchasing power differently across housing markets. In higher-priced states, even small improvements in interest rates translate into substantial lifetime dollar savings. Conversely, in lower-cost states, the penalty for not having top-tier credit is often proportionally larger relative to loan amount and income.

“This data reinforces just how central credit preparation is to homebuying affordability,” said Max Slyusarchuk, CEO of AD Mortgage. “Two borrowers with similar incomes can experience dramatically different buying power depending on their credit score and the state in which they purchase. Even a 20- or 30-point difference in FICO can mean tens of thousands of dollars over the life of a mortgage.”

Study Methodology and Assumptions:

The report uses a combination of publicly available data and modeled scenarios, including:

• The estimated time required for consumers in each state to improve their FICO score to 760
• The difference in 30-year mortgage interest payments between average-score borrowers and 760+ borrowers
• The impact on affordability relative to state household income levels
• Mortgage assumptions based on a 30-year fixed-rate using state median home prices and a standardized 15% down payment
