Credit Score Guide: How Your Score Affects Your Mortgage

Your credit score is the single biggest factor in your mortgage rate. Learn what score you need, how scores are calculated, and proven strategies to improve yours before applying.

Credit Score Tiers & Mortgage Impact

Lenders use your FICO score to determine your interest rate and loan eligibility. Even a small score improvement can save thousands over the life of your loan. Here is how different score ranges affect your options:

What Makes Up Your Credit Score

Payment History (35%)
On-time payments are the most important factor. Even one 30-day late payment can drop your score 60-100 points. Set up autopay on all accounts.
Credit Utilization (30%)
The percentage of available credit you are using. Keep balances below 30% of limits — under 10% is ideal. Pay down credit cards before applying for a mortgage.
Credit History Length (15%)
Average age of your accounts matters. Do not close old credit cards before applying — it shortens your history and increases utilization.
Credit Mix (10%)
Having different types of credit (cards, auto loans, student loans) shows you can manage various obligations. Do not open new accounts just for this.
New Credit (10%)
Multiple hard inquiries in a short period can lower your score. Exception: mortgage shopping within 14-45 days counts as one inquiry.

How to Improve Your Credit Score

Quick Wins (30-90 Days)
  • Pay down credit card balances to below 30% utilization — this is the fastest score boost
  • Dispute errors on your credit report at AnnualCreditReport.com — errors are surprisingly common
  • Become an authorized user on a family member's old, low-balance card
  • Do NOT close old accounts or open new ones before applying
  • Set up autopay on every account to prevent late payments
  • Ask for a credit limit increase (without a hard pull) to lower utilization
