Your credit score is one of the most powerful numbers in your financial life — especially when getting a mortgage. A difference of just 50-100 points can mean tens of thousands in interest costs or the difference between approval and rejection.
This guide covers everything you need to know about credit scores and mortgages—from minimum requirements to how rates affect you.
Key Takeaways
Minimum Scores Vary by Loan Type:
Some FHA lenders accept credit scores of 580+, conventional lenders often require 620+, and better rates are often available with higher credit scores.
Your Score Directly Impacts Your Rate:
Even a 20-point difference can affect your interest rate, which can add up over a 30-year loan.
Lenders Check More Than Just Your Score:
Payment history, credit utilization, credit mix, and recent inquiries all matter.
You May Be Able to Improve Your Score in 3-6 Months:
Strategic actions such as paying down balances and disputing errors can help increase your score.
Timing Matters:
Avoid new credit applications and major purchases in the 3-6 months before applying for a mortgage.
💡 Pro Tip: Once your credit is mortgage-ready, don't settle for the first rate you're offered. Upload your Loan Estimate to Fincast and let vetted lenders compete to beat your rate — no extra credit pulls, no spam.
Credit Score Ranges: What Lenders See 📊
Lenders use FICO scores ranging from 300-850:
740+ (Excellent):
Typically allows the most loan options at attractive rates and terms.
700-739 (Good):
Often allows for competitive rates with strong approval odds.
620-699 (Fair):
This is the conventional loan threshold for many lenders, but it may come with higher rates and stricter requirements.
580-619 (Below Average):
FHA loans are possible with 3.5% down with many lenders. They often come with higher rates and always require mortgage insurance.
Below 580 (Poor):
Some lenders may accept this credit score for FHA loans, but FHA requires a minimum 10% down payment. Focus on credit repair before applying.
What Lenders Actually Look At Beyond Your Score 🔍
Your three-digit score isn't the whole story. Lenders also consider:
Payment History (35% of your score):
Late payments, collections, and charge-offs may impact approval. Recent issues are more concerning, but each lender has different criteria.
Credit Utilization (30%):
Keep balances under 30% of limits, ideally under 10%. High utilization signals financial stress to lenders.
Length of Credit History (15%):
A longer track record is better because it shows a longer history of how you manage your finances. Don't close old cards before applying.
Credit Mix (10%):
Having multiple credit types demonstrates your ability to manage various obligations and may look favorable to some lenders.
New Credit Inquiries (10%):
Multiple hard inquiries can hurt your score, but mortgage shopping within 45 days counts as one inquiry, which is why the sooner you shop for your mortgage rates, the better.
How to Improve Your Credit Score Before Applying 📈
If you need to boost your score, follow this 3-6 month action plan:
1. Pay Down Credit Card Balances:
One effective way to improve your score is to pay down your credit card balances—target under 30% utilization, ideally under 10%. Pay balances before statement dates. (Utilization refers to your amount of outstanding debt compared to your total credit line.)
2. Dispute Any Credit Report Errors:
Check all three bureaus at AnnualCreditReport.com. Dispute incorrect late payments, wrong balances, or unknown accounts.
3. Make All Payments On Time:
Set up autopay and maintain a 6-month perfect payment history.
4. Become an Authorized User:
Ask a family member with excellent credit to add you to their card. Their positive history may boost your score if the creditor reports authorized users to the credit bureaus.
This works best when the primary cardholder maintains low balances and a good payment history.
5. Keep Old Credit Cards Open:
Closing cards reduces available credit and shortens your credit history, both of which can hurt your credit.
6. Avoid New Credit Applications:
Each inquiry may drop your score by a few points. Avoid new credit for 3-6 months before applying.
Common Credit Mistakes to Avoid Before Applying ⚠️
Don't max out credit cards to save cash for a down payment — high utilization can negatively affect your score
Don't finance furniture before closing — lenders re-check credit before final approval
Don't close credit cards — the less credit you have available, the more it increases your utilization and shortens your credit history
Don't co-sign loans — you're 100% responsible if they miss payments, and it can negatively affect your debt-to-income ratio
Don't ignore small collections — even small amounts can derail approval
Don't switch jobs before applying — most lenders need 2 years of steady income
