How Do I Improve My Credit to Buy a House?

If you’re thinking about buying a home but you’re worried that your credit score may hold you back, you’re not alone. One of the most common questions future homebuyers ask is, “How do I improve my credit to buy a house?”

The good news is that your credit score is not necessarily permanent. Depending on what is affecting your credit, there may be steps you can take to improve your credit profile before applying for a mortgage.

Even better, you may not need a perfect credit score to buy a house. Different mortgage programs have different requirements, and your credit score is only one part of the overall qualification process.

In this guide, we’ll explain how credit affects your mortgage, what may be hurting your score, which actions can potentially improve it, what you should avoid doing before buying a home, and when it makes sense to speak with a mortgage professional.


Why Does Your Credit Score Matter When Buying a House?

Your credit score helps a mortgage lender evaluate how you have managed borrowed money in the past. But qualifying for a mortgage involves more than simply reaching a particular credit score.

A lender may evaluate factors including:

  • Your credit score
  • Your payment history
  • Your current debts
  • Your debt-to-income ratio (DTI)
  • Your income and employment
  • Your available assets and reserves
  • Your down payment
  • The type of mortgage you’re applying for
  • The property you’re purchasing

Your credit can also affect the cost of your mortgage. Depending on the loan program, a stronger credit profile may help you qualify for better pricing, a lower interest rate, or lower mortgage insurance costs.

That means improving your credit isn’t only about getting approved. It may also reduce the cost of borrowing money.


What Credit Score Do I Need to Buy a House?

There is no single credit score required to buy a house.

The minimum score can vary based on the mortgage program, automated underwriting findings, down payment, loan-to-value ratio, debt-to-income ratio, lender requirements, and other factors.

For example, conventional mortgages are evaluated using guidelines established by agencies such as Fannie Mae and Freddie Mac, while government-backed programs such as FHA, VA and USDA have their own requirements.

More importantly, meeting a minimum credit score does not automatically mean you’ll qualify, and having a lower score doesn’t necessarily mean homeownership is out of reach.

Mortgage underwriting considers your entire financial profile.

How Do I Improve My Credit to Buy a House?

If your goal is to improve your credit before applying for a mortgage, start with the information actually appearing on your credit reports. Your strategy should depend on why your score is where it is today.

Here are some of the most important areas to review.

1. Check All Three of Your Credit Reports

Before trying to fix your credit, find out what’s actually being reported.

Review your credit reports from all three major credit bureaus:

  • Equifax
  • Experian
  • TransUnion

Look carefully for incorrect late payments, accounts that don’t belong to you, incorrect balances, duplicate accounts, outdated information, or accounts incorrectly reported as delinquent.

You can obtain your credit reports through AnnualCreditReport.com.

Important: Checking your own credit report does not hurt your credit score.

2. Dispute Legitimate Credit Reporting Errors

If information on your credit report is inaccurate, you have the right to dispute it.

Don’t dispute accurate information simply because it’s negative. Instead, focus on legitimate reporting errors and provide documentation supporting your dispute whenever possible.

An error could be particularly important when preparing for a mortgage because inaccurate negative information may affect both your credit score and your ability to qualify.

3. Pay Every Bill on Time

Payment history is one of the most important factors used in calculating a FICO credit score.

If you’re preparing to buy a home, avoiding new late payments should be a priority. Set up automatic payments or reminders if necessary so that accounts aren’t accidentally missed.

A single new late payment while you’re preparing for a mortgage can potentially undo some of the progress you’ve made elsewhere.

4. Reduce Credit Card Balances

Credit card balances can have a significant effect on your credit score because scoring models consider how much of your available revolving credit you’re using.

This is commonly called your credit utilization ratio.

For example, if you have a credit card with a $10,000 limit and a $7,500 balance, you’re using 75% of that available credit.

Reducing revolving balances may improve your credit profile. It can also potentially help your mortgage qualification by reducing your required monthly debt payments.

However, don’t assume that paying off every debt is automatically the best mortgage strategy. Money used to pay down debt may also be needed for your down payment, closing costs or reserves.

Before moving a large amount of money around, talk with your mortgage broker about where those funds may help you the most.

5. Don’t Close Old Credit Cards Just Because They’re Paid Off

Paying down a credit card and closing the account are two different things.

Closing a revolving account can reduce the amount of available credit you have. In some situations, that can increase your overall utilization percentage.

Older accounts may also contribute to the length of your credit history.

Unless there’s a specific reason to close an account, don’t automatically start closing credit cards simply because you’re preparing to buy a home.

6. Avoid Opening Unnecessary New Credit

That new furniture promotion offering 0% financing may look attractive, but immediately before buying a house may not be the ideal time to start opening accounts.

New credit can potentially affect your credit score and create additional monthly obligations that must be considered when qualifying for your mortgage.

When you’re getting ready to buy, avoid unnecessary:

  • Credit cards
  • Auto loans
  • Personal loans
  • Furniture financing
  • Buy-now-pay-later accounts

This becomes even more important once you’ve applied for a mortgage.


Should I Pay Off Collections Before Applying for a Mortgage?

Not necessarily.

This is an area where homebuyers frequently make decisions before talking with their mortgage professional.

Whether a collection should be paid can depend on the type of collection, amount owed, age of the account, mortgage program, underwriting requirements and how the account is being reported.

Paying a collection does not guarantee that your credit score will increase. The effect depends on the scoring model and the rest of your credit profile.

If your primary objective is qualifying for a mortgage, speak with your mortgage broker before paying old collections solely because you believe doing so will increase your score.


Should I Pay Off Credit Cards Before Buying a House?

Paying down credit cards can sometimes be one of the more effective ways to improve a borrower’s credit profile, particularly when revolving balances are high.

But there’s another reason credit card debt matters when you’re buying a house: debt-to-income ratio.

Your required monthly credit card payments generally count toward your monthly debts when qualifying for a mortgage.

Reducing those balances may therefore accomplish two things:

  1. Potentially improve your credit profile.
  2. Potentially reduce your monthly debt obligations.

But don’t drain the savings you need to complete your home purchase just to chase a higher credit score.

A mortgage professional can help you determine whether your available money is better used toward debt reduction, down payment, closing costs or reserves.


How Much of My Credit Card Limit Should I Use?

You may have heard that you should always keep your credit utilization below a specific percentage, such as 30%.

There isn’t one universal percentage that guarantees a particular credit score.

In general, however, lower revolving balances relative to your available credit can be better for your credit profile than consistently carrying high balances.

Both your overall utilization and the balances on individual revolving accounts can matter.

That’s why randomly spreading money across several credit cards may not always produce the best result. If you’re close to qualifying for a mortgage, ask your mortgage professional whether a targeted paydown strategy makes sense for your situation.


How Long Does It Take to Improve Credit to Buy a House?

There is no universal timeline.

Some credit profiles may change relatively quickly after revolving balances are reduced and the new balances are reported to the credit bureaus. Other situations require months of establishing positive payment history.

More serious negative credit events may take considerably longer to overcome.

Your timeline depends on factors such as:

  • Why your score is currently low
  • How recently negative information occurred
  • Your credit card balances
  • Whether your credit report contains errors
  • The age of your accounts
  • Your recent payment history
  • Whether you have enough active credit history

This is why generic advice such as “wait six months” isn’t necessarily useful. One borrower may need time. Another may simply need a credit card balance to update.


Can I Improve My Credit in 30 Days to Buy a House?

Sometimes meaningful changes can occur within a relatively short period, but nobody can responsibly guarantee that your score will increase by a specific number of points within 30 days.

If high revolving balances are depressing your score, paying them down and allowing the updated balances to report could potentially produce a change relatively quickly.

Correcting a legitimate credit reporting error could also affect your credit profile once the information is updated.

On the other hand, if your credit issues involve recent late payments, charge-offs or a limited credit history, improvement may require more time.

The first question shouldn’t be “How do I gain 50 points?” It should be “What is causing my score to be where it is?”


What Should I NOT Do When Trying to Improve My Credit?

Improving credit isn’t just about what you do. It’s also about avoiding actions that could make your situation worse.

If you’re planning to buy a house soon, be cautious about:

  • Opening multiple new credit accounts
  • Closing older credit cards without understanding the effect
  • Running credit cards up after paying them down
  • Missing payments while saving for a down payment
  • Financing a vehicle immediately before buying a house
  • Co-signing a loan for someone else
  • Paying collections without first discussing your mortgage strategy
  • Moving large amounts of money without keeping documentation
  • Making major financial changes after mortgage preapproval

Once you’re preapproved for a mortgage, it’s especially important to communicate with your loan originator before making significant changes to your credit or finances.


Does Checking My Credit Hurt My Credit Score?

Checking your own credit report does not hurt your credit score.

There is a difference between a consumer checking their own credit and a lender accessing credit as part of a credit application.

Don’t avoid reviewing your credit because you’re afraid that simply looking at it will lower your score.

Knowing what’s on your credit report gives you time to identify problems before you’re under contract to purchase a home.


Why Is My Mortgage Credit Score Different From Credit Karma?

This surprises many homebuyers.

You don’t have just one credit score.

Different scoring models can produce different scores using information from your credit reports. The score shown by a consumer credit-monitoring service may therefore be different from the score used during the mortgage process.

Mortgage lending has traditionally relied heavily on specific FICO scoring models, although the mortgage industry is undergoing changes in the credit scoring models approved for certain loans.

So don’t assume that a score you see through a free consumer app will be identical to the score your mortgage lender receives.


What If I Have Bad Credit Right Now?

Having imperfect credit doesn’t automatically mean you can’t buy a home.

The more useful question is whether your current credit profile qualifies for an available mortgage program and, if not, what specifically needs to change.

You may discover that you’re closer than you thought.

Depending on your circumstances, options could include FHA financing, conventional financing, VA financing for eligible borrowers, USDA financing for eligible properties and borrowers, or waiting while you work on specific credit issues.

Is a Higher Credit Score Always Better for a Mortgage?

Generally, stronger credit can provide more financing options and potentially better loan pricing. But that doesn’t mean you should postpone buying indefinitely while trying to achieve a “perfect” credit score.

The better question is:

Would improving my credit further create a meaningful improvement in my mortgage options or cost?

If the answer is yes, waiting and improving your credit may be worth considering.

If your current credit already provides access to competitive financing and the improvement wouldn’t materially change your loan, waiting solely to chase a higher number may not accomplish much.

This is where reviewing actual mortgage scenarios can be more useful than focusing on a credit score by itself.


Should I Use a Credit Repair Company Before Buying a House?

Be cautious with any company promising a guaranteed credit score increase, a specific number of points, or the removal of accurate negative information.

Legitimate errors can be disputed. Accurate negative information generally cannot simply be erased because it is inconvenient.

Before paying someone to “repair” your credit, consider starting with your credit reports and identifying exactly what needs attention.

If your ultimate goal is buying a house, your mortgage professional may also be able to help identify which credit issues are actually preventing you from qualifying.


A Simple Credit Checklist Before Buying a House

If you’re hoping to purchase a home in the next several months, start here:

  1. Review all three credit reports.
  2. Identify and dispute legitimate errors.
  3. Make every payment on time.
  4. Reduce high revolving credit card balances when appropriate.
  5. Avoid unnecessary new debt.
  6. Don’t automatically close old accounts.
  7. Don’t make assumptions about collections.
  8. Build your savings at the same time.
  9. Talk with a mortgage professional before making major credit changes.

Talk to a Mortgage Professional Before You Start “Fixing” Everything

One of the biggest mistakes prospective homebuyers make is assuming they need to repair every negative item on their credit before talking to a mortgage professional.

You don’t necessarily need to do that.

At Galaxy Lending Group, we can review your overall mortgage scenario and help you understand where you stand today.

If you’re not ready to qualify yet, knowing why is valuable. Instead of guessing, you can focus on the specific areas that may actually help you become mortgage-ready.

You may need to reduce a credit card balance. You may need additional positive payment history. You may need to address an error. Or you may discover that your current credit is already sufficient for an available mortgage option.

Don’t assume you have to wait to buy a home simply because your credit isn’t perfect.

Frequently Asked Questions About Improving Credit to Buy a House

How can I raise my credit score before buying a house?

Start by reviewing your credit reports for errors, making every payment on time, reducing high revolving credit card balances when appropriate, avoiding unnecessary new credit and maintaining responsible credit usage. The best strategy depends on what is currently affecting your individual credit profile.

How fast can I improve my credit to buy a house?

There is no guaranteed timeline. Some borrowers may see changes after lower credit card balances are reported, while others may need several months or longer to establish a stronger payment history or recover from negative credit events.

Should I pay off all my debt before applying for a mortgage?

Not necessarily. Paying down certain debts may improve your credit or debt-to-income ratio, but using all your available cash to eliminate debt could leave you short on funds needed for a down payment, closing costs or reserves. Review your complete financial picture before deciding.

Will paying off a collection improve my credit score?

It depends on the account, how it is reported and the credit scoring model being used. Paying a collection does not guarantee a particular credit score increase. If you’re preparing for a mortgage, speak with your mortgage professional before paying a collection solely to improve your score.

Does checking my own credit lower my score?

No. Checking your own credit report does not lower your credit score.

Can I buy a house with a 600 credit score?

Potentially. Mortgage eligibility depends on more than the credit score alone. Loan program, down payment, debt-to-income ratio, credit history, assets and underwriting results can all affect qualification. Read our complete guide to buying a house with a 600 credit score.

Do I need perfect credit to buy a house?

No. Homebuyers can qualify for mortgages with a wide range of credit profiles. The loan options and terms available to you will depend on your complete financial situation and the mortgage program.

What is the best credit score to buy a house?

There isn’t one score that is “best” for every borrower. Higher scores can generally provide access to better mortgage pricing and additional options, but the point at which another increase materially improves your mortgage can vary by loan program and scenario.


Start Preparing for Homeownership Today
