Your credit score is the single most important factor in determining your mortgage rate. A 740+ score gets you the best rates (6.09% in August 2026), while a 620 score could cost you an extra 1.5% — that is $333/month more on a $400,000 loan. This guide shows you exactly how to raise your score fast.

Quick Summary: Minimum scores: FHA 580, VA 580, conventional 620, USDA 640, jumbo 700. Best rates at 740+. Pay down cards to under 10% utilization for 20-50 point gain in 30 days. Ask your lender about rapid rescore. Do not open new credit or close old accounts before applying.

Credit Repair: What Works and What Does Not

What Works

  • Paying down credit card balances
  • Disputing factual errors on credit reports
  • Becoming an authorized user on a good account
  • Goodwill letters for one-time late payments
  • Pay-for-delete on collections
  • Rapid rescore through your lender
  • Experian Boost for utility/phone payments
  • Bringing past-due accounts current

What Does Not Work

  • Paying credit repair companies $500-$1,500
  • Disputing accurate negative items (they come back)
  • Closing old accounts to "clean up" credit
  • Opening new cards to increase available credit
  • Paying off all installment loans early
  • Using a CPN (Credit Privacy Number) — it is illegal
  • Filing bankruptcy to "start fresh" for a mortgage
  • Consolidating debt right before applying

FICO vs VantageScore: Which Do Lenders Use?

FeatureFICO ScoreVantageScore
Used by Mortgage LendersYes (90%+ of lenders)Rarely for mortgages
Score Range300-850300-850
Mortgage-Specific VersionFICO Score 2, 4, 5 (older models)VantageScore 4.0
Free Monitoring ServicesSome banks offer FICO 8Credit Karma, most free apps
Key DifferenceStricter on late payments, collectionsMore forgiving of old negatives

Important: The credit score you see on Credit Karma (VantageScore) may be 20-50 points higher than the FICO score your mortgage lender pulls. Always check your FICO score before applying for a mortgage. Many banks and credit card companies provide free FICO scores to their customers. Get pre-approved with a lender that uses your actual FICO mortgage score.

Frequently Asked Questions

Can I get a mortgage with a 580 credit score?

Yes. FHA accepts 580 with 3.5% down. VA lenders typically require 580. However, your rate will be ~8% vs 6.09% for 740+. Improving your score just 60 points (to 640) saves ~$2,844/year. Check FHA pre-approval with your current score.

How much does credit score affect mortgage rate?

A 740+ score gets ~6.09% while a 620 gets ~7.5%. On a $400K loan, that is $372/month difference ($4,464/year). Every 20-point improvement can save $50-$100/month. Compare lenders to find the best rate for your score.

Does paying off collections improve my credit score?

Not immediately. Paid collections still show on your report for 7 years. However, newer FICO models (9, 10T) ignore paid collections. Negotiate pay-for-delete to remove them entirely. Get pre-approved and ask your lender about rapid rescore.

Should I refinance to improve my rate after raising my credit score?

If you bought at 620-680 credit and now have 740+, refinancing could save $200-$400/month. Typical refinance costs $2,500-$5,000, recovered in 7-20 months. Check your refinance savings with improved credit.
