Can You Buy a House With Someone Who Has Bad Credit?
You’ve found someone you genuinely want to buy a house with.
Maybe it’s your best friend, your sibling, or a family member you’ve been talking about buying property with for years.
You’ve discussed the neighborhoods you like, how much you can contribute toward a down payment, and what kind of home would work for both of you.
Then you start talking about credit scores.
Yours is 760.
Theirs is 605.
Suddenly, you’re wondering whether buying together is still possible.
Will your friend’s credit score prevent you from qualifying for a mortgage?
Will the lender overlook your excellent credit because your co-buyer has a much lower score?
Could you end up paying a higher interest rate?
Or would it make more sense for only one person to apply?
You can potentially buy a house with someone who has bad credit, but the way lenders evaluate your application depends on the mortgage program and both borrowers’ financial circumstances.
Recent mortgage credit-scoring changes have also made some of the older advice about joint applications incomplete.
Here’s what co-buyers should understand before applying.
Can Two People With Different Credit Scores Buy a House Together?
Yes, potentially.
Having a co-buyer with a lower credit score does not automatically make purchasing a home together impossible.
However, mortgage lenders evaluate more than your combined income and down payment.
They also examine your credit histories, existing debts, savings, employment, and ability to repay the proposed mortgage.
When you apply together, both applicants are evaluated under the requirements of the selected loan program.
This means a stronger credit profile from one borrower may help the overall application, but it does not automatically eliminate concerns about the other person’s credit history.
The outcome depends on the lender’s underwriting process.
Why Your Co-Buyer’s Credit Score Matters
A credit score helps lenders evaluate how an applicant has managed borrowed money.
It can influence whether a mortgage is approved and how much borrowing may cost.
When two people apply together, lenders need to assess the risks associated with both borrowers.
For example, your friend might have a strong income but a history of late payments.
You might have excellent credit but a lower income.
The lender will evaluate the proposed mortgage using the applicable underwriting rules rather than simply selecting the most favorable characteristic of each person.
Understanding those rules can help you make an informed decision about whether to apply together.
Whose Credit Score Counts on a Joint Mortgage?
This is one of the most important questions for co-buyers.
The answer depends on the mortgage program and how the application is underwritten.
For certain conventional mortgages, Fannie Mae distinguishes between two different credit score calculations:
The representative credit score
This is generally the lowest applicable score among the borrowers and is used for mortgage pricing purposes.
The average median credit score
For certain manually underwritten mortgages involving multiple borrowers, this average is used to determine whether the loan meets the minimum credit score requirement.
These scores serve different purposes.
Fannie Mae explains the distinction in its official credit score determination guidance. Fannie Mae Selling Guide
Example: One Co-Buyer Has Excellent Credit
Imagine Maya and Jordan want to purchase a house together.
Maya’s applicable mortgage credit score is 605.
Jordan’s applicable mortgage credit score is 735.
For this simplified example, assume these are the scores selected under the same credit-scoring model.
Their financial situation looks like this:
| Co-Buyer | Credit Score |
| Maya | 605 |
| Jordan | 735 |
| Average median credit score | 670 |
| Representative credit score | 605 |
Their average median credit score is:
(605 + 735) ÷ 2 = 670
Under Fannie Mae’s current requirements, certain manually underwritten fixed-rate mortgages involving multiple borrowers use the average median score when determining whether the minimum credit score requirement is met.
The published minimum for those manually underwritten fixed-rate mortgages is 620.
In this example, the average score of 670 exceeds that threshold.
However, this does not guarantee approval.
The lender must still evaluate the borrowers’ credit histories, income, debt, property, loan-to-value ratio, and other requirements.
The lower score may also continue to affect mortgage pricing.
For Fannie Mae loans, the representative credit score remains relevant to loan-level price adjustments.
So even when a stronger borrower’s score helps the application meet an eligibility threshold, the lower score can still influence the cost of borrowing. Fannie Mae Selling Guide
Did Mortgage Credit Score Requirements Change in 2026?
Yes.
Several important credit-scoring developments have affected conventional mortgage underwriting.
Fannie Mae’s Current Credit Score Requirements
Fannie Mae’s Selling Guide distinguishes between manually underwritten loans and loans evaluated through Desktop Underwriter, commonly called DU.
For manually underwritten mortgages, its published minimum scores include:
| Mortgage Type | Published Minimum Credit Score |
| Manually underwritten fixed-rate mortgage | 620 |
| Manually underwritten adjustable-rate mortgage | 640 |
| Desktop Underwriter loan casefile | No fixed minimum credit score required by DU |
For loans evaluated through DU, the system assesses creditworthiness using broader risk factors rather than applying a universal minimum score.
That does not mean someone with poor credit automatically qualifies.
The automated evaluation still considers the credit information and other financial risks associated with the application.
Individual lenders may also apply additional requirements.
These distinctions are explained in Fannie Mae’s general credit score requirements. Fannie Mae Selling Guide
VantageScore 4.0 Became More Widely Available
Another change occurred on September 9, 2026.
Fannie Mae and Freddie Mac expanded VantageScore 4.0 availability to all approved lenders for eligible loans.
This allows lenders to use an additional approved scoring model alongside the established Classic FICO framework.
The Federal Housing Finance Agency also confirmed changes to loan-level pricing adjustments on September 30, 2026.
These developments matter because different approved credit-scoring models may evaluate certain aspects of borrowing history differently.
However, a lender must follow the applicable scoring requirements and cannot simply combine whichever individual scores produce the highest result.
As of October 25, 2026, FHFA states that FICO 10T is not yet eligible for loans delivered to Fannie Mae and Freddie Mac. FHFA.gov
What This Means for Co-Buyers With Different Scores
If you’re considering a joint mortgage with low credit, don’t assume that a number you saw in an older article automatically determines your eligibility.
Ask the lender:
Which mortgage program are we being evaluated under?
Is the application being assessed through automated or manual underwriting?
Which credit-scoring model is being used?
How does the lower borrower’s score affect mortgage pricing?
Would the result change if we applied with only one borrower?
These questions can help you understand your actual options.
Can Two People With Different Credit Scores Qualify for an FHA Loan?
Potentially.
FHA loans have their own credit requirements.
They do not follow every rule applicable to conventional mortgages.
For FHA financing, the minimum decision credit score generally reflects the lowest applicable borrower-level score among the borrowers whose scores are used.
That means one person’s excellent credit does not simply replace another borrower’s lower score.
What Changes for FHA Loans in 2027?
On October 8, 2026, the FHA issued Mortgagee Letter 2026-11.
The letter expands its credit-scoring framework to accommodate VantageScore 4.0 and FICO 10T alongside Classic FICO.
The changes take effect for FHA case numbers assigned on or after January 1, 2027.
The letter also confirms that FHA’s existing minimum credit score thresholds remain unchanged.
Under the updated methodology, the lender first determines an applicable score for each borrower and then uses the lowest borrower-level score to establish the loan’s minimum decision credit score.
Different scoring models may be submitted, but the applicable model requirements must be followed consistently across borrowers. HUD
Does a Lower FHA Credit Score Mean Automatic Rejection?
Not necessarily.
FHA establishes program-level credit requirements, but lenders also evaluate income, debt, credit history, and other underwriting factors.
A lender may impose requirements that are stricter than the program minimum.
This is why someone considering an FHA mortgage with a co-buyer who has a weaker credit profile should seek a lender-specific assessment rather than relying on a generalized credit score rule.
It’s also worth comparing the available conventional and FHA options.
A mortgage professional can explain which programs are appropriate for the borrowers and property involved.
Should You Apply Together or Have One Person Apply?
This is where co-buying decisions become more complicated.
Suppose you have excellent credit, stable income, and savings.
Your friend has a weaker credit profile but earns significantly more money.
Would it be better for you to apply alone?
Possibly.
But the answer depends on whether you can qualify for the mortgage using your own income and financial resources.
Option 1: Apply Together
Under a joint mortgage application, both borrowers’ eligible incomes may be considered.
This can improve purchasing power when both applicants have sufficient qualifying income.
However, the lender also evaluates both borrowers’ debts and credit profiles.
A stronger combined income may be helpful, but the lower credit score could increase borrowing costs or create underwriting challenges.
Option 2: Apply With One Borrower
If one person has substantially stronger credit, the co-buyers might explore having that person apply for the mortgage individually.
This could produce a different underwriting result.
However, the lender generally cannot include the other person’s income simply because the two intend to share household expenses.
The mortgage applicant must qualify under the selected program’s requirements.
Example: Comparing the Two Options
Maya and Jordan want to purchase a $400,000 home.
Their financial profiles are:
| Financial Detail | Maya | Jordan |
| Credit score | 605 | 735 |
| Annual income | $85,000 | $55,000 |
| Available down payment savings | $20,000 | $25,000 |
Together, they have $140,000 in annual income and $45,000 in down payment savings.
However, the lender must also evaluate their existing debts and applicable credit requirements.
If Jordan applies alone, the lender may evaluate the application using Jordan’s $55,000 income and other qualifying financial information.
That may improve the credit profile considered for underwriting while reducing the amount of income available to support the loan.
Neither option is automatically better.
The co-buyers should compare actual lender assessments before deciding how to structure their application.
Can Someone Be a Co-Owner Without Being on the Mortgage?
Potentially.
Being legally responsible for a mortgage and owning an interest in a property are related but separate matters.
Depending on the loan program, lender requirements, state law, and transaction structure, a person may be able to hold an ownership interest without being a borrower on the mortgage.
However, this arrangement should not be assumed to be available for every transaction.
The lender may require property owners to sign certain security documents, and other conditions may apply.
Why This Matters When One Buyer Has Bad Credit
Imagine Maya and Jordan decide that Jordan will apply for the mortgage alone.
Maya still plans to contribute part of the down payment.
Before proceeding, they need to establish whether Maya can hold an ownership interest and how the lender will treat her contribution.
They should also discuss what happens if the partnership changes.
Important questions include how Maya’s contribution will be documented, whether it creates ownership rights, and how each person will be compensated if the home is eventually sold.
These matters should be addressed with the lender and an appropriate real estate attorney before closing.
What Are the Financial Risks of a Joint Mortgage?
A lower credit score does not automatically mean someone will be an unreliable co-buyer.
A person’s credit history may reflect circumstances that have since changed.
However, it is still important to understand the financial risks involved.
1. Higher Mortgage Costs
A lower credit score may affect the interest rate or other borrowing costs offered by the lender.
Even when a joint application qualifies, the resulting mortgage may be more expensive than another available arrangement.
2. Mortgage Approval Challenges
The lender may identify credit issues that require further documentation or additional underwriting review.
These can include recent late payments, unresolved debts, or other credit-history concerns.
3. Shared Responsibility for the Loan
If both people sign the mortgage, both can be legally responsible for the debt.
A private agreement to split payments does not necessarily limit either borrower’s responsibility to the lender.
If one person cannot pay their agreed share, the other may need to cover the difference to keep the mortgage current.
4. Different Financial Habits
Two people may have different approaches to borrowing, saving, budgeting, and managing unexpected expenses.
These differences can become more significant when they share a long-term financial obligation.
5. Difficult Exit Decisions
If one person wants to leave the ownership arrangement, the remaining owner may need to qualify for refinancing or another approved solution.
That can be difficult if their financial circumstances do not support the mortgage independently.
These risks should be discussed before the purchase.
Pairgap’s guide on finding a trustworthy co-buyer explores additional financial and partnership considerations.
What Are the Benefits of Buying Together Despite Different Credit Scores?
There can still be advantages to co-buying when the parties have different credit profiles.
Combined Financial Resources
Two eligible borrowers may be able to combine qualifying income and available funds.
This can expand the range of properties they are able to consider.
Shared Housing Expenses
Co-buyers can agree to divide mortgage payments, property taxes, homeowners insurance, and maintenance expenses.
That may reduce the amount each person needs to contribute individually.
A More Realistic Homeownership Plan
Some prospective buyers may be able to explore homeownership sooner by working with a financially prepared partner.
However, the purchase should remain affordable under the actual mortgage terms offered.
Structured Financial Accountability
Co-buying creates an opportunity to establish shared financial expectations.
Both parties can agree on budgeting, recordkeeping, and how to respond when circumstances change.
These benefits depend on the borrowers, the property, and the terms of the arrangement.
Buying together should be a deliberate financial decision.
How Can Co-Buyers Improve Their Mortgage Readiness?
If one person has a lower credit score, the most useful next step is to understand the factors affecting their credit history and identify realistic opportunities for improvement.
A stronger application begins with accurate information.
Step 1: Review Both Credit Reports
Each prospective borrower should review their credit reports.
Look for incorrect account information, reporting errors, unpaid balances, and late-payment records.
Credit scores can differ depending on the scoring model used.
The score displayed by a banking app may not be the same score a mortgage lender uses.
Step 2: Understand Existing Debt
Credit scores are only part of mortgage qualification.
Lenders also evaluate debt obligations.
For example, an applicant might have a relatively strong credit score but significant monthly debt payments.
Another might have a lower score but comparatively little outstanding debt.
Both situations require a broader financial assessment.
Step 3: Identify Areas for Improvement
Depending on the circumstances, useful preparation may include making payments consistently on time, reducing revolving credit balances, and correcting credit-report errors.
Avoid opening unnecessary new credit accounts shortly before applying for a mortgage.
A qualified housing counselor can help prospective borrowers understand their options.
Step 4: Review the Combined Financial Picture
Before applying, compare both borrowers’ income, existing debts, savings, and expected housing expenses.
Include the full anticipated monthly cost of ownership.
That means considering the mortgage payment, property taxes, homeowners insurance, maintenance, and any applicable homeowners association fees.
Pairgap’s co-buying preparation checklist provides a broader guide to these conversations.
Step 5: Compare Mortgage Options
Different lenders and loan programs may produce different results.
When comparing offers, examine the complete cost of borrowing.
The Consumer Financial Protection Bureau recommends comparing interest rates, mortgage insurance, upfront loan costs, total monthly payments, and cash required at closing.
The CFPB also explains that Loan Estimates can help consumers negotiate with lenders. Consumer Financial Protection Bureau
Step 6: Decide Whether You’re Financially Ready to Buy Together
Sometimes, the best next step is to continue preparing.
One person might need additional time to improve their credit profile.
Another might need to reduce debt or build savings.
The goal is to choose a purchase and financing arrangement both people can realistically sustain.
Should Credit Scores Determine Whether Two People Are Compatible Co-Buyers?
Credit scores matter.
But they don’t explain everything about how two people will work together.
Imagine two friends.
One has a 780 credit score but avoids discussing money and refuses to establish a shared budget.
The other has a 640 score, understands what affected their credit, and has spent the past year consistently improving their finances.
The credit scores provide useful financial information.
They do not independently tell you which person will communicate better, follow an agreed budget, or handle disagreements responsibly.
Financial Compatibility Requires More Than a Number
Before buying together, discuss how each person manages financial responsibilities.
Consider your approaches to saving, spending, borrowing, and handling unexpected costs.
You should also understand how each person makes decisions under pressure.
A home requires ongoing financial cooperation.
Knowing how someone approaches those responsibilities can be as important to your partnership as understanding their credit score.
Pairgap’s Real Estate Partner Test helps prospective co-buyers explore their approaches to money, communication, decisions, and partnership.
It is a compatibility and self-understanding tool, not a mortgage credit assessment.
What This Means for Co-Buyers
Having different credit scores doesn’t automatically mean two people cannot buy a home together.
But it does mean they should take a closer look at how the financing will work.
Understand Both Financial Profiles
Each person should know what they bring to the purchase.
That includes qualifying income, savings, debt obligations, credit history, and financial expectations.
Compare the Available Mortgage Structures
A joint application may produce a different result from an individual application.
The right option depends on the actual underwriting requirements and the financial position of the borrowers.
Be Clear About Ownership
Mortgage responsibility and ownership interests should be discussed separately.
If the parties contribute different amounts or use a mortgage structure involving only one borrower, their legal arrangements should reflect the intended ownership and financial responsibilities.
Prepare for Financial Changes
Co-buyers should decide what happens if one person loses income, cannot make their agreed contribution, or wants to leave the arrangement.
They should also establish procedures for major expenses and disagreements.
A written agreement can help organize these expectations.
Pairgap’s Real Estate Prenup helps co-buyers document their ownership plans, contributions, responsibilities, and exit arrangements for appropriate legal review.
Make the Decision Together
The purpose of reviewing credit scores is to understand the financial position of the proposed partnership.
Both people should have enough information to make an informed decision about whether to move forward.
A strong co-buying arrangement requires financial preparation, clear communication, and realistic expectations.
Frequently Asked Questions
1. Can You Buy a House With Someone Who Has Bad Credit?
Yes, potentially.
Mortgage eligibility depends on the loan program, both borrowers’ financial profiles, and the lender’s underwriting requirements.
A lower credit score may affect approval or borrowing costs, but it does not automatically make every joint mortgage application ineligible.
2. Does a Mortgage Lender Use the Lowest Credit Score?
It depends on the mortgage program and the purpose of the score calculation.
For Fannie Mae mortgages, the representative score generally uses the lowest applicable borrower score for pricing.
Certain manually underwritten loans with multiple borrowers use an average median score to evaluate minimum credit eligibility.
Other mortgage programs have different rules.
3. Can One Person’s Good Credit Offset Another Person’s Bad Credit?
Sometimes, a stronger borrower’s score can improve the loan-level eligibility calculation.
For example, Fannie Mae uses average median scores for certain manually underwritten mortgages involving multiple borrowers.
However, a higher score does not erase another borrower’s credit history or guarantee favorable loan pricing.
4. Can You Get a Joint FHA Mortgage if One Borrower Has a Low Credit Score?
Potentially.
FHA financing has its own credit requirements and uses the applicable minimum decision credit score.
The lower borrower’s score can affect eligibility.
Lender requirements and the complete financial application also matter.
5. Is It Better to Apply for a Mortgage Alone if My Co-Buyer Has Weak Credit?
Possibly, but not always.
An individual application may be evaluated using the stronger borrower’s credit profile.
However, the lender generally cannot include the excluded person’s income simply because the two intend to share housing expenses.
Compare the available options with a mortgage professional.
6. Can Someone with a Weaker Credit Profile Still Contribute to the Down Payment?
Potentially.
The source of down payment funds, the borrower’s relationship to the other applicant, and the intended ownership arrangement must satisfy the selected mortgage program’s requirements.
If someone contributes funds without becoming a mortgage borrower, the parties should clarify how the contribution is treated and whether it creates an ownership interest.
