How Score Affects Your Rate (Real Numbers)
On a $300,000 30-year fixed mortgage — same home, same lender, same day — here's what your credit score actually costs you:
| Credit Score | Est. Rate | Monthly P&I |
|---|---|---|
| 760–850 | 6.50% | $1,896 |
| 700–759 | 6.72% | $1,939 |
| 680–699 | 6.89% | $1,973 |
| 660–679 | 7.10% | $2,013 |
| 640–659 | 7.54% | $2,101 |
| 620–639 | 8.10% | $2,214 |
A 620 vs. 760 score = $318/month more = $114,480 extra over 30 years. On the same house.
Minimum Scores by Loan Type
Conventional (Fannie/Freddie)
Best rates require 740+. Below 620 = denied.
FHA Loan
500–579 OK with 10% down. MIP for life of loan often.
VA Loan (veterans)
No VA minimum, but lenders set their own floor (~620).
USDA Loan (rural)
Income and location limits apply.
Jumbo Loan (>$766,550)
Stricter standards — large loan, higher risk.
Fastest Ways to Improve Your Score
Pay down credit card balances
30–60 daysHigh impactGet utilization under 10% on every card. This is the fastest lever. Paying from 50% to 10% utilization can add 40–80 points.
Pay the statement balance before closing date
1 billing cycleHigh impactBalances report to bureaus on your statement closing date — not your due date. Pay before that date to show $0 or minimal balance.
Dispute any errors on your report
30–45 daysHigh impact1 in 5 credit reports has errors. Pull yours free at AnnualCreditReport.com. Dispute inaccuracies with each bureau directly.
Become an authorized user on a family member's old card
1–2 monthsMedium impactIf a parent or partner has a long-standing card with low utilization, being added as an AU can boost your score with no spending required.
Don't close old credit cards
OngoingMedium impactClosing cards reduces your available credit and can shorten your average account age — both hurt your score.
Avoid new credit applications for 6–12 months before applying
Pre-planningMedium impactEach hard inquiry drops your score 5–10 points. Stack several in one year and lenders see risk. Go quiet for 6–12 months before mortgage application.
Never Do These Between Pre-Approval & Closing
- ✗ Finance a car, furniture, or appliances
- ✗ Open a new credit card — even for a store discount
- ✗ Miss any payment on any account
- ✗ Move large sums of money between accounts without documentation
- ✗ Quit or change jobs (lenders re-verify employment before closing)
Timing Your Credit & Application
Pull your credit report 6–12 months before you plan to buy — not when you're ready to apply.
Give yourself at least 3–6 months to make improvements before applying for pre-approval.
Rate-shop multiple lenders within a 14–45 day window — FICO counts them as one inquiry.
Lock your rate when you go under contract — rates can change daily.
Avoid ANY new debt (car loans, credit cards, furniture financing) between pre-approval and closing.
Key Takeaways
A 620 vs. 760 score on a $300K mortgage can cost $100,000+ in extra interest over 30 years. This is the most impactful number in homebuying.
Pull your report at AnnualCreditReport.com at least 6 months before you plan to buy.
Paying down credit card balances is the fastest way to boost your score — results show in 30–60 days.
Never open new credit or take on new debt between pre-approval and closing. It can kill your deal.
