Knowing what factors affect a credit score helps tenants understand how lenders and landlords assess financial reliability. Simple actions can significantly impact your score quickly. Paying bills late, skipping loan instalments, or using most of your available credit can cause the credit score to drop.

For example, maxing out a credit card or missing rent for one month demonstrates poor financial management. On the other hand, paying on time, lowering credit utilization, and keeping old accounts open can raise your score within weeks.

A strong credit report with a positive payment history enhances your appearance in a tenant credit check. When renters manage these key credit score factors, they make future rental applications easier and more confident.

What factors affect a credit score and their percentage weights

Why Credit Score Matters for Tenants?

A credit score acts as a snapshot of your financial habits. For tenants, it’s one of the first things a landlord reviews during a rental credit check. The specific score a landlord is looking for can vary, and knowing what credit score is needed to rent an apartment can give you a major advantage in competitive markets.

A high score indicates to landlords that you manage your finances responsibly and pay bills on time, which helps build trust before signing a lease. On the other hand, a poor credit score can raise concerns about missed rent or future payment issues.

Your tenant's credit score directly impacts several parts of the renting process:

  • Rental approval: A good score helps your application stand out, especially in competitive markets. For instance, a tenant with a 720 score may get approved faster than someone with a 580 score, even if they have similar income.
  • Security deposits: Landlords often lower deposits for tenants who show strong credit management. If your score is high, you might pay only half a month’s rent as a deposit, while a lower score could increase it to two months.
  • Lease terms: A healthy score can help you secure better rental terms, such as flexible payment dates or renewal benefits. Poor credit may limit these options or result in stricter terms.

A low score doesn’t necessarily mean you can’t rent, but it can make the process more challenging. Landlords may ask for a co-signer, a higher deposit, or proof of steady income. In addition to reviewing your score, landlords also verify tenant income to ensure you can afford the rent, which is why a complete application package is crucial.

That’s why improving your credit score before applying is essential. Besides, it's also important to understand what landlords look for in a credit check, as their review goes beyond just the three-digit number. When tenants and landlords have a clear understanding of each other's financial reliability, it helps build mutual trust. Good credit benefits both sides, leading to fair rental terms, easy approvals, and long-term rental stability.

5 Main Factors That Affect A Credit Score

Keeping balances low improves what factors affect a credit score

Knowing the 5 factors of a credit score helps tenants see where to focus their efforts. Each affects your credit differently, shaping your financial profile. However, it's also worth noting the differences between a credit score vs credit report, as the report contains the detailed history that generates the score. Here's a breakdown:

1. Payment History (35%)

Your payment history is the most significant factor, accounting for approximately 35% of your score. It reflects whether you pay bills on time, including loans, credit cards, and possibly rent if reported. Consistent on-time payments are the foundation of a high credit score. Credit scoring models treat late payments based on how overdue they are:

  • A 30-day late payment causes significant damage and is the most common severity reported.
  • A 60-day late payment is more damaging than a 30-day late payment.
  • A 90-day late payment (or more) is the most harmful and shows greater financial distress. The damage increases exponentially with the length of the delay.

Payment status, the severity of late payments, history of defaults, and collections all factor into this score segment. Late or missed payments greatly harm your credit; consistent on-time payments build it.

For tenants, paying rent on time can be a valuable asset. Services that report rent payments, such as those discussed by LeaseRunner, help illustrate a positive payment history to potential landlords.

2. Credit Utilization (30%)

Credit utilization measures how much of your available credit you use. It accounts for roughly 30% of your credit score, making it the second most important factor after payment history. If you use too high a percentage of your credit limits, it suggests financial strain to lenders and landlords.

Keeping utilization low (ideally under 30% and optimally under $10) shows good money management. For tenants, understanding how a credit score is calculated means recognizing that reducing balances boosts your score quickly.

Besides, it is important to understand the difference between the two main types of debt, as they are treated differently in the utilization calculation:

  • Revolving Credit: includes accounts like credit cards and lines of credit. You can borrow, pay back, and borrow again up to a set limit. This is the only type of debt used to calculate your utilization ratio. Because of this, maxing out a credit card will severely impact your score.
  • Installment Debt: includes accounts like mortgages, auto loans, and student loans. With this debt, you borrow a fixed amount and repay it over a set period in fixed monthly payments. The total balance on these loans does not factor into your credit utilization ratio.

Because utilization only considers revolving accounts, focusing on paying down credit card balances is the most effective way to manage this 30% of your score. Monitoring this through credit reports or tenant screenings helps maintain a healthy credit image.

3. Length of Credit History (15%)

Alt: New credit inquiries impact what factors affect a credit score

The length of your credit history counts for about 15% of your score. This factor measures your experience using credit. Longer histories with positive activity are viewed favorably by lenders. Key components are: 

  • Age of Oldest Account: The older your first account, the better.
  • Age of Newest Account: Lenders prefer not to see a large number of very new accounts.
  • Average Age of Accounts (AAoA): This averages the age of all your open accounts.

The impact of these account changes is:

  • Adding New Accounts: Opening a new account (starting at zero age) temporarily reduces your AAoA, causing a slight, short-term dip in your score.
  • Closing Accounts: Accounts closed in good standing stay on your report for up to 10 years, contributing to your history. However, never close your oldest account. Once it eventually drops off, it will drastically reduce your AAoA and negatively impact your score.

For tenants and new users, patience is key, as positive activity builds a strong history over time.

4. New Credit Inquiries (10%)

When you apply for new credit, it generates inquiries that temporarily lower your score. It's beneficial to know the difference between a soft and hard credit check, as only hard inquiries impact this portion of your score.

These inquiries account for about 10%. Multiple hard inquiries in a short time can signal financial distress and reduce your score more noticeably. Tenants should understand what can harm their credit score, including excessive applications. For example, submitting too many rental applications or opening multiple credit cards within a short period could harm your credit score.

5. Credit Mix (10%)

Your credit mix reflects the various types of credit, including credit cards, loans, and mortgages, which contribute roughly 10% to your score. A diverse mix shows you can handle various credit responsibly. Landlords may also request credit references as part of a rental application to gain a more comprehensive view of your financial history and reliability.

While tenants may not have diverse credit yet, building a healthy mix over time supports score growth. This is part of what makes up a credit score and is helpful in long-term financial planning.

All in all, understanding the weight of these five factors is the first step toward building and maintaining excellent credit. For tenants and borrowers alike, the takeaway is clear: Payment History (35%) and Credit Utilization (30%) are the most critical areas for immediate attention, totalling a massive 65% of your score. 

By consistently paying all debts on time, keeping revolving balances low, and exercising patience as your Length of Credit History (15%) matures, you can actively shape a strong financial profile that opens doors to better loan rates and smoother rental approvals.

What Factor Hurts Your Credit Score the Most?

Length of credit history factor in credit score calculation

Among all credit score factors, payment history has the largest impact. It accounts for approximately 35% of your total credit score and reflects your consistent payment history for bills and debts. Late or missed payments on credit cards, loans, or rent can result in an immediate drop in your score and leave a negative mark for up to seven years

For tenants, this means one missed payment can affect both future rental options and loan approvals. Here are the main actions that can hurt your credit score the most:

  • Missed or late payments: Failing to pay your credit card bill or loan installment by the due date is the biggest red flag. For example, missing a 300 car payment by more than 30 days can lower your score by 90 points or more. The longer the delay, the greater the damage.
  • Defaulted loans or collections: Unpaid accounts that go to collections heavily damage your report. This includes rent, as it’s important to know what happens when unpaid rent goes to collections, which can severely drop your score. Even after you pay them off, they remain visible to lenders for years.
  • High credit utilization: Using too much of your available credit also hurts. Experts recommend keeping balances under 30% of your credit limit. For instance, if your credit card limit is $1,000, try to keep your balance under $300. Regularly paying down balances shows responsible borrowing.
  • Many hard inquiries: Each time you apply for a new credit card or loan, a lender performs a hard inquiry. Taking on too many loans in a short period can make it appear that you are accumulating excessive debt.

To protect your credit score, focus on making timely payments, keeping credit usage low, and avoiding unnecessary credit applications. Even the question of whether breaking a lease hurts your credit is primarily determined by whether the resulting charges or debt are sent to a collection agency.

Tenants preparing for a rental credit check can benefit from these habits, as landlords often view strong payment records as proof of reliability. For more guidance, LeaseRunner’s article on how to pass a rental credit check offers practical advice on improving your credit score and maintaining a healthy credit profile that appeals to both landlords and lenders.

How to Improve Your Credit Score Before Renting

Improving your credit score before applying for a rental can make the approval process smoother and help you secure your ideal home. A good credit score shows landlords that you pay bills on time and manage debt responsibly. While some actions can improve your score quickly, steady habits over time make the biggest difference. Follow the steps below to strengthen your credit and increase your chances of renting successfully.

Short-Term Strategies: Quick Steps to Boost Your Score

These are actions you can take right away to raise your credit score within a few weeks or months. They help clean up your report and fix issues that might be lowering your score.

  • Step 1: Pay past-due bills immediately. Bring any overdue accounts up to date as soon as possible. Even one unpaid bill can hurt your score by showing missed payments. Contact creditors to set up payment plans if needed—many will work with you to get back on track.
  • Step 2: Lower credit card balances. High balances can quickly lower your credit score. Try to use no more than 30% of your credit limit. For instance, if your credit card has a $1000 limit and your balance is $900, paying it down to below $300 can bring a noticeable improvement within a billing cycle or two.
  • Step 3: Review your credit report for errors. Check reports from all three credit bureaus, Equifax, Experian, and TransUnion. Mistakes, such as incorrect late payments or accounts you never opened, can appear and unfairly reduce your score. Dispute these errors online so they can be corrected within 30 days.
  • Step 4: Avoid taking on new credit. Multiple credit applications can result in hard inquiries on your credit report. Each inquiry can slightly reduce your score, especially if you submit several within a short time. Wait until after your rental process is complete before opening new lines of credit.
  • Step 5: Set up automatic payments for bills. Payment history makes up the largest portion of your credit score. Enrolling in auto-pay helps you avoid missed or late payments, ensuring you establish a record of reliability that landlords value highly.

Long-Term Strategies: Building Consistent Credit Health

Reducing debt quickly boosts what factors affect a credit score

These habits take time but lead to lasting results. They help you maintain a strong credit score, which makes future rentals or loans easier to secure.

  • Step 1: Always pay on time. Making consistent, on-time payments every month builds trust with lenders. Even after past late payments, continued reliability slowly repairs damage and raises your score.
  • Step 2: Keep old accounts active. Closing old credit cards can shorten your credit history, which may negatively impact your credit score. Keep long-standing accounts open, even if you use them only lightly, to show stable, long-term credit use.
  • Step 3: Mix different types of credit. Use both revolving credit (such as credit cards) and instalment loans (like car or student loans) responsibly. This mix demonstrates your ability to manage different repayment types, which adds strength to your profile.
  • Step 4: Maintain low utilization. Regularly keep balances below 30% of your total available credit. If possible, make small payments throughout the month to keep balances low and reduce interest charges.
  • Step 5: Monitor your credit often. Knowing how to check your tenant screening report is vital because it shows exactly what the landlord will see, including potential red flags. Checking your credit monthly helps you catch errors early and track your progress. Tools like LeaseRunner’s tenant screening reports make it simple to view updates and confirm that your hard work is improving your score.

Following these short-term improvements and long-term habits not only boosts your credit score but also builds a reputation for financial responsibility. When landlords see a strong credit history, they view you as a dependable renter who pays on time and manages money wisely.

Conclusion

Understanding the factors that affect a credit score gives tenants long-term control over their financial standing. A strong score builds trust with landlords and makes rental applications smoother. Paying a rental application fee is a standard part of the rental application process; however, submitting a complete application with a strong score increases the likelihood that the fee is well spent.

Keeping a clean credit report starts with steady actions, paying every bill on time, keeping credit utilization low, and avoiding unnecessary loan inquiries. For instance, paying down a credit card from $900 to $300 on a $1,000 limit shows real progress. Reviewing your payment history monthly helps identify errors early, before they negatively impact your score. 

The credit check conducted by the landlord, which you can perform yourself, is a crucial step in the rental process. This is also why services like LeaseRunner’s credit check tools are helpful. With consistent habits and awareness, renters can protect their credit record and secure better housing opportunities.

FAQs

1. What percentage of your credit score is based on your payment history?

Payment history makes up about 35% of your credit score. It tracks if you pay your credit cards, loans, and bills on time. Paying a credit card or car payment by its due date each month can help raise your credit score. However, missing one payment for 30 days or more can result in a significant drop. To stay on track, use alerts or auto-pay so payments never slip through the cracks. Even small, steady payments help your score grow over time.

2. Can your credit score go negative?

No, credit scores never go negative. The lowest score is usually around $300, and the highest is about $850. If your score is very low, it means lenders see a higher risk. This high-risk profile may also lead landlords to look for a higher resident score vs credit score for their internal assessment.

This can make it more challenging to rent a home, obtain new credit cards, or qualify for a loan. Paying off overdue bills and reducing balances can help raise your score again. Think of 300 as the bottom floor; your goal is to keep climbing upward.

3. Does paying rent build credit?

Yes, paying rent can help build credit when reported to credit bureaus. Rent on its own doesn’t help unless you use a rent-history sharing service. These tools share your rent history with credit agencies. For example, if you pay $1,000 in rent every month and your landlord reports it, you can see your score rise after a few months of on-time payments. 

This helps renters without past credit build trust for future loans. In severe cases of non-payment, a landlord may decide to report a bad tenant to a credit bureau, which can negatively impact the tenant's credit score.

4. How do you improve a credit score quickly?

To improve your credit score fast, focus on a few key actions. Pay down large credit card balances to lower your credit utilization, which should stay under 30%. For example, reduce a $900 balance on a $ 1,000 limit card to around $200. Fix errors on your credit report by filing online disputes. Also, avoid applying for new credit too often. Each step strengthens your payment record and improves your score.
