Book a ConsultationHow Credit Score Affects Your Rate
Your credit score is one of the biggest factors in the rate you qualify for — but it is not the only one.
Your Middle FICO Score
Lenders pull scores from all three credit bureaus (Equifax, Experian, TransUnion). They use the middle score — not the highest, not the lowest. If you have two scores, they use the lower one.
Every 20 Points Matters
Mortgage pricing adjusts at roughly 20-point increments. Moving from 679 to 700, or from 739 to 740, can drop your rate and save thousands over the life of the loan.
Score Is Not Everything
Your debt-to-income ratio, down payment amount, loan type (FHA, VA, conventional), and property type all factor into your final rate. Score is the starting point, not the finish line.
The Five Factors That Build Your Score
Understanding what moves your score is the first step toward improving it.
Payment History
Pay on time, every time. Even one 30-day late payment can drop your score significantly.
Credit Utilization
Keep balances below 30% of your credit limits. Below 10% is even better for mortgage applications.
Length of History
Older accounts help your score. Avoid closing your oldest credit card, even if you rarely use it.
Credit Mix
A healthy mix of installment loans (car, student) and revolving credit (cards) shows you can manage different types.
New Inquiries
Limit new credit applications. Multiple mortgage inquiries within 14–45 days count as one for scoring purposes.
Mortgage Scores vs. Free Score Apps
Free score apps like Credit Karma, Credit Sesame, and your bank typically show your VantageScore. Mortgage lenders use a different model: FICO. These can differ by 20–80 points in either direction.
When a lender pulls your credit, they get scores from all three bureaus. The middle score is what determines your pricing tier. If only two scores are available, the lower one is used.
The score you see online is a useful trend indicator — if it is going up, that is good. But do not count on it being the exact number a lender sees. The only way to know your mortgage-ready FICO score is through a lender credit pull.
