Short answer
Why lenders use FICO 2/4/5, how the middle score is chosen, and what changes your number.
Mortgage lenders pull all three bureaus and use the middle of your three FICO scores. For joint applicants, they use the lower middle score.
Tri-merge and middle score
Mortgage lenders pull all three bureaus and use the middle of your three FICO scores. For joint applicants, they use the lower middle score.
What moves the number
Payment history and utilization drive the largest changes. New credit and hard inquiries have smaller, shorter-term impact.
Key takeaways
- Middle score matters, not the highest.
- Utilization is a fast lever.
