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 may affect your options:
| Score Range | Rating | Rate Impact | Loan Options |
|---|---|---|---|
| 760+ | Excellent | Best available rates | All loan types, best terms |
| 700–759 | Good | +0.125–0.25% | All loan types, good terms |
| 660–699 | Fair | +0.25–0.50% | Most loans, some restrictions |
| 620–659 | Below Average | +0.50–1.00% | Conventional (limited), FHA |
| 580–619 | Poor | +1.00–1.50% | FHA only (3.5% down) |
| 500–579 | Very Poor | +1.50%+ | FHA only (10% down required) |

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.
