Your credit score plays a crucial role in your ability to buy a home, but many homebuyers don’t realize just how much it affects their mortgage terms. While most people know that credit scores impact interest rates, they also influence loan approval, down payments, mortgage insurance, fees, and even homeowners insurance.
A difference of just 50 points in your credit score could mean paying thousands more over the life of your mortgage. If you’re planning to buy a home, understanding these hidden ways your credit score affects your mortgage can help you save money and secure better loan terms.
In this guide, we’ll uncover seven surprising ways your credit score influences your home loan—and what you can do to improve your financial standing before applying for a mortgage.
Interest Rates: The Higher Your Score, The Lower Your Rate
One of the most significant ways your credit score affects your mortgage is by determining the interest rate you qualify for. Mortgage lenders assess your credit score to measure risk, and a higher score means lower risk, which leads to a better interest rate.
How Much Can a Low Credit Score Cost You?
Even a small difference in your credit score can result in thousands of dollars in extra interest payments over the life of a mortgage.
For example, if you’re applying for a 30-year fixed mortgage of $300,000, here’s how different credit scores could impact your interest rate:
- Credit Score 760+ → 5.50% interest rate → Monthly Payment: $1,703
- Credit Score 700-759 → 5.75% interest rate → Monthly Payment: $1,751
- Credit Score 640-699 → 6.50% interest rate → Monthly Payment: $1,896
- Credit Score Below 620 → 7.25% interest rate → Monthly Payment: $2,048
That’s a difference of $345 more per month (or over $124,000 in extra interest over 30 years) just because of a lower credit score!
How to Improve Your Credit Before Applying for a Mortgage
✅ Pay bills on time – Your payment history makes up 35% of your credit score.
✅ Reduce credit card balances – Keep your credit utilization below 30% for the best rates.
✅ Avoid opening new credit accounts – New credit inquiries can lower your score before you apply.
✅ Check your credit report for errors – Dispute any inaccuracies that could be dragging down your score.
A higher credit score not only lowers your monthly payment but also saves you tens of thousands of dollars over the life of your mortgage.
Loan Approval Odds: Your Score Determines Whether You Qualify
Your credit score doesn’t just affect how much interest you’ll pay—it also determines whether you can get approved for a mortgage at all. Different loan types have minimum credit score requirements, and a lower score can limit your loan options or require you to jump through extra hoops to get approved.
Minimum Credit Score Requirements by Loan Type
- Conventional Loans – Minimum score of 620, but 740+ is ideal for the best rates.
- FHA Loans – Requires a 580+ score (or 500-579 with a 10% down payment).
- VA Loans – No official minimum, but most lenders prefer 620+.
- USDA Loans – Generally requires a 640+ score for approval.
If your credit score is below these thresholds, you may face denials or need a much larger down payment to compensate for the lender’s risk.
How a Low Credit Score Makes Loan Approval More Difficult
✅ Fewer Loan Options – Many lenders won’t approve borrowers with scores below 620-640, limiting your choices.
✅ Higher Down Payment Requirements – A lower score could mean putting down 10-20% instead of 3-5%.
✅ More Scrutiny from Lenders – Low credit scores may lead to manual underwriting, requiring extra income documentation, higher reserves, or proof of consistent rent payments.
How to Improve Your Chances of Loan Approval
✅ Increase your score before applying – Work on paying down debt and improving payment history at least 6-12 months in advance.
✅ Consider FHA or VA loans – If your score is below 620, FHA and VA loans may provide better approval odds.
✅ Get a co-signer – If you have a trusted family member with strong credit, this can improve your chances of getting approved.
Getting approved for a mortgage is harder with bad credit, but not impossible. Taking proactive steps to boost your score can make a significant difference in securing better loan terms and lower costs.
Down Payment Requirements: Bad Credit = Higher Down Payment
Your credit score doesn’t just affect your loan approval—it can also determine how much of a down payment you need. The lower your score, the more lenders require upfront to offset the risk of default.
How Credit Score Affects Down Payment Requirements
- Excellent Credit (740+) → Can qualify for 3% down (conventional loan) or 0% (VA/USDA loan).
- Good Credit (680-739) → Usually 3-5% down for conventional loans.
- Fair Credit (620-679) → Lenders may require 5-10% down.
- Poor Credit (Below 620) → May need 10-20% down, or be denied a conventional loan.
FHA Loans & Down Payment Options for Lower Credit Scores
✅ If your credit score is at least 580, you can get an FHA loan with just 3.5% down.
✅ If your credit score is between 500-579, FHA loans require 10% down.
✅ Conventional lenders often reject applicants with scores below 620, forcing buyers into FHA loans or higher down payments.
Why Lenders Require Higher Down Payments for Low Credit Scores
✅ Higher risk of default – Borrowers with low credit are statistically more likely to miss payments.
✅ Protecting the lender – A bigger down payment gives the lender a buffer in case of foreclosure.
✅ Compensating for weak financial history – If your credit report shows missed payments or high debt, a larger down payment proves you’re financially committed.
How to Reduce Your Down Payment Requirement
✅ Boost your credit score – Even a 20-30 point increase can help you qualify for lower down payments.
✅ Explore first-time homebuyer programs – Many state and federal programs offer down payment assistance for buyers with lower scores.
✅ Save aggressively – If you know your credit score is low, start saving months (or years) in advance to meet higher down payment requirements.
A higher credit score = a lower down payment, allowing you to buy a home with less upfront cash. If your score is low, improving it before applying can help you qualify for better loan options with lower upfront costs.
Mortgage Insurance Costs: Higher Credit = Lower PMI Payments
If you put less than 20% down on a home, you’ll likely have to pay private mortgage insurance (PMI) or mortgage insurance premiums (MIP) if using an FHA loan. What many buyers don’t realize is that your credit score affects how much you pay for mortgage insurance.
How Credit Score Affects PMI Costs
✅ Higher Credit Score = Lower PMI Rates – Borrowers with excellent credit (740+) pay significantly less in PMI.
✅ Lower Credit Score = Higher PMI Costs – If your score is below 680, PMI rates can be double or triple what high-credit borrowers pay.
For example, if you take out a $300,000 mortgage with 10% down, here’s how PMI costs change based on credit score:
- 760+ credit score → PMI = $100/month
- 700-759 credit score → PMI = $140/month
- 620-699 credit score → PMI = $225/month
- Below 620 credit score → PMI = $300+/month
A lower credit score could mean paying an extra $2,400+ per year in PMI fees!
PMI for Conventional Loans vs. FHA Loans
- Conventional loans – PMI is based on credit score and down payment size.
- FHA loans – MIP is fixed, but borrowers with higher credit scores can refinance later to remove it.
How to Reduce or Eliminate PMI
✅ Increase your credit score before applying – Even a 20-30 point improvement can lower PMI costs.
✅ Make a larger down payment – If you put down 20% or more, PMI is completely avoided.
✅ Refinance later – Once you reach 20% equity, you can request PMI removal on a conventional loan.
Your credit score directly affects how much you pay for mortgage insurance. Improving your score before buying can save you thousands in PMI fees over the life of the loan.
Loan Fees & Closing Costs: Bad Credit Can Cost You More
Your credit score doesn’t just impact your interest rate and mortgage insurance—it also affects how much you pay in loan fees and closing costs. Lenders often charge more in fees to borrowers with lower credit scores to compensate for the higher risk.
How Credit Score Affects Loan Fees
✅ Higher Credit Score = Lower Fees – Borrowers with good credit (700+) often pay fewer upfront fees.
✅ Lower Credit Score = Higher Fees – If your credit score is below 640, lenders may charge higher origination fees or require discount points to get a reasonable interest rate.
Common Extra Fees for Low Credit Score Borrowers
- Higher Loan Origination Fees – Some lenders charge 1-2% of the loan amount to cover processing costs.
- Discount Points Requirement – Borrowers with low credit may need to pay for points upfront to lower their interest rate.
- Higher Title & Lender Fees – A lower credit score can result in higher administrative and underwriting costs.
For example, on a $300,000 mortgage, a borrower with a 760+ credit score might pay $3,000 in closing costs, while someone with a 620 credit score could pay $5,000 or more in fees.
How to Reduce Loan Fees & Closing Costs
✅ Improve Your Credit Before Applying – Even a small score increase can reduce origination fees and points.
✅ Shop Around for Lenders – Compare multiple mortgage offers to find lower fees and better rates.
✅ Negotiate with the Lender – Ask if they can waive or lower origination and processing fees.
✅ Use Seller Concessions – Some sellers may cover part of the closing costs to help finalize the sale.
A low credit score can increase your mortgage fees by thousands of dollars, but improving your score, shopping around, and negotiating can help cut costs.
Loan Term Flexibility: Higher Scores Get More Options
Your credit score doesn’t just affect how much you pay for a mortgage—it also determines which types of loan terms are available to you. Borrowers with higher credit scores have more flexibility in choosing their loan structure, while those with lower scores may be limited to fewer, often more expensive, options.
How Credit Score Affects Loan Terms
✅ Higher Credit Score = More Loan Term Choices – Borrowers with good to excellent credit (700+) can choose between 15-year, 20-year, or 30-year mortgages, as well as fixed-rate or adjustable-rate loans (ARMs).
✅ Lower Credit Score = Fewer Options – Borrowers with low credit scores (below 640) may only qualify for longer-term loans (30+ years) with higher rates.
Why Loan Term Flexibility Matters
- Shorter-Term Loans Save Money – A 15-year loan has a lower interest rate and saves thousands in interest over time.
- Adjustable-Rate Mortgages (ARMs) Offer Initial Savings – High-credit borrowers can access low introductory rates, while lower-credit borrowers may only qualify for fixed high-rate loans.
- Longer Loan Terms Cost More Overall – Low-credit borrowers often end up with 30-year+ terms, resulting in higher interest payments over time.
For example, on a $250,000 loan:
- A 760+ credit score borrower could qualify for a 15-year loan at 4.75%, paying around $1,945 per month and $99,000 total interest.
- A 620-640 credit score borrower might only qualify for a 30-year loan at 6.75%, paying $1,621 per month but $332,000 total interest over time.
How to Improve Loan Term Options
✅ Increase Your Credit Score Before Applying – Even a small increase unlocks better loan terms.
✅ Save for a Larger Down Payment – A bigger down payment can help offset a lower credit score.
✅ Improve Your Debt-to-Income Ratio – Lenders may approve shorter-term loans if your debts are low.
✅ Compare Lenders & Loan Products – Some lenders offer more flexible terms for mid-range credit scores.
Having a high credit score gives you more control over your mortgage structure, which can lead to major savings over the life of your loan.
Homeowners Insurance Rates: A Surprising Factor
Most homebuyers focus on interest rates, down payments, and closing costs, but one hidden way your credit score affects your mortgage is through homeowners insurance costs. Many people don’t realize that insurance companies use credit scores to assess risk, which means a lower credit score can lead to higher premiums.
How Credit Score Affects Homeowners Insurance Costs
✅ Higher Credit Score = Lower Insurance Premiums – Borrowers with a good credit score (700+) typically pay less for homeowners insurance.
✅ Lower Credit Score = Higher Premiums – Borrowers with credit scores below 640 can see insurance rates increase by 25% or more.
✅ Credit-Based Insurance Scores Are Used – Insurers calculate a separate insurance-specific credit score, which impacts your premium even if your mortgage lender doesn’t consider it.
Why Insurance Companies Use Credit Scores
- Studies show that borrowers with lower credit scores file more insurance claims, making them higher-risk customers.
- Insurers charge higher premiums to offset potential future claims.
- If your score is low, you may not qualify for discounts that high-credit homeowners receive.
How to Lower Homeowners Insurance Costs
✅ Improve Your Credit Score – Raising your credit score by even 20-30 points can help lower your premium.
✅ Shop Around for Insurance Quotes – Compare multiple insurance providers to find better rates.
✅ Bundle Policies – Combining home and auto insurance with the same provider can save up to 25%.
✅ Raise Your Deductible – Opting for a higher deductible can reduce monthly premiums.
How Much Can You Save?
- A 760+ credit score homeowner might pay $1,200/year for insurance.
- A 640-679 credit score homeowner might pay $1,600/year—an extra $400 annually.
- A below 620 credit score homeowner might pay $2,000/year or more, leading to thousands in extra costs over time.
While most people don’t associate credit scores with home insurance, improving your credit can lower your monthly housing costs and reduce your total mortgage expenses.
