Buying a home doesn't have to be a solo journey. If you're a homebuyer facing a competitive housing market, a joint mortgage could be the key to making homeownership more accessible and affordable. By combining financial resources with another borrower, you can share both the responsibility and the opportunity to purchase a home.

This comprehensive guide covers everything you need to know about joint mortgages. You'll discover how they work, what it takes to qualify, and the important advantages and disadvantages to consider. Whether you're thinking about taking this path with a spouse, family member, or friend, this resource provides the insights you need to make an informed decision about your home purchase strategy.

Key takeaways:

• A joint mortgage is a home loan where two or more people combine their financial profiles to qualify for financing together.
• All borrowers on a joint mortgage are completely legally responsible for paying back the loan, regardless of how they choose to split the payments personally.
• Removing yourself from a joint mortgage usually requires selling the home or refinancing the loan entirely into a different person’s name.

What is a joint mortgage?

In a joint mortgage, all parties apply together, combine their financial profiles, and share the legal responsibility for repaying the debt. Unlike an individual mortgage in which there is only one borrower who is solely responsible for repaying the loan, a joint mortgage allows two or more parties to pool their financial resources and potentially qualify for a bigger or otherwise better loan than they could’ve been approved for on their own.

The Department of Veterans Affairs (VA) has its own definition.¹ A joint VA loan is one in which either more than one client is using the VA entitlement, or the eligible VA client is applying with someone who isn’t their spouse.

Joint mortgage vs. joint ownership

Unlike joint ownership, which involves two parties equally taking on the legal ownership of a property, a joint mortgage has nothing to do with whose name is on the deed. Being on the mortgage means you are financially responsible for the loan, but it does not automatically give you property rights.

With a joint mortgage, at least two parties are responsible for the loan – even though one of them may not have their name on the deed and possess ownership of the property. Property ownership rights are determined entirely by who is listed on the home's title or deed.

“A joint mortgage only tells you who owes the lender money, while joint ownership tells you who owns the property legally,” says Dennis Shirshikov, a professor of economics and finance at City University of New York/Queens College. “You can have a joint mortgage without also owning the property. For example, a parent can co–sign the loan but not be on the deed. On the other hand, two friends can co–own property through an LLC, but only one of them, for example, may be on the mortgage.”

Joint mortgage vs. single mortgage

When deciding between a joint mortgage and a single mortgage, it’s essential to look at the financial profiles of everyone involved. A joint mortgage may help immensely if you need to combine incomes to qualify for a larger loan amount or if you need to pool your savings to afford the down payment and closing costs. It's often the push many buyers need to finally get into the housing market.

However, a single mortgage may be better if your potential co–borrower has a significant amount of debt, a low credit score, or unstable employment. Because lenders evaluate the combined income, debts, and credit scores of all applicants, a co–borrower’s poor financial standing can drag down the strength of the entire application.

In some situations, buying a house without your spouse on the mortgage application could result in a lower interest rate and better loan terms if your individual credit profile is strong enough to qualify on its own.

How do joint mortgage loans work?

When you buy a house with a joint mortgage, you share responsibility for the loan with at least one other person. The process works very similarly to getting an individual mortgage, but with added scrutiny.

While joint mortgage applicants are often married couples, you don’t have to be married to the other party on your loan – you just both have to qualify and, in most cases, be at least age 18.

The factors a lender will consider when deciding whether you qualify for a home loan are pretty much the same ones they’d examine if you applied for a mortgage by yourself.

Your lender will look at borrower credit scores, income, debt, and employment history. Everyone who will be on the loan must submit a complete mortgage application and agree to a hard credit check.

If you’re approved, both you and the other party or parties involved will sign a promissory note at the closing table. As co–borrowers, you’ll each be equally responsible for making payments on the loan, though one of you can make the payments on behalf of the pair or group.

If you aren't sure how you want to structure your application, it's a good idea to understand the difference between a co–borrower vs. cosigner. A co–borrower shares the asset, lives in the home, and usually contributes to the monthly payments. A co–signer puts their credit on the line to help you get approved, but they don't typically live in the home or intend to make the regular payments – though they are fully liable in the event of default.

How many people can be on a joint mortgage?

There’s no legal limit to how many people can be on a mortgage, but lenders may set their own policies and the rules can differ depending on whether it’s a conventional mortgage or a government-backed loan. At Rocket Mortgage, no matter the loan type, the maximum number of clients allowed is no more than four.

Remember that everyone on the loan also must qualify for the financing to be approved, and some lenders may see a big group of names as a massive risk.

“Including more than one borrower on a mortgage can make the process more complex, since the lender must thoroughly investigate each person’s earnings, liabilities, and credit history,” real estate attorney and REALTOR® Bruce Ailion says. “While the group’s overall financial profile and total debt–to–income ratio are weighed, lenders often expect every applicant to meet certain baseline qualifications individually. A problem in just one borrower’s application can slow things down – or even cause the whole mortgage to be denied.”

Whose credit score do lenders use?

When you get a joint mortgage, your lender will look at the credit history and credit scores of all applicants who will be on the loan. Since everyone’s credit will impact the loan, you qualify for, a poor credit score can be detrimental to you or the person you’re applying with. For joint applications, lenders base their decision on the lowest middle credit score among all applicants.

“Each borrower has three scores – one from each major credit bureau – and the middle value is used for underwriting,” says Ailion. “For example, if one borrower’s scores are 760, 720, and 700, their middle score is 720. If the other borrower’s scores are 680, 670, and 660, their middle score is 670. In this case, the lender would rely on 670 for determining loan terms and eligibility. This cautious method helps safeguard the lender against the greater risk associated with the applicant who has the weaker credit profile.”

It’s important to review your qualifications, including credit, with your co–borrower prior to applying to avoid any surprises. Looking at credit reports can give you the opportunity to read potential mistakes in the reporting and lower DTI by paying down existing debts, for example.

If your credit score or the credit score of a co–borrower is making it difficult to get a joint mortgage, other options exist. You may still be able to qualify for joint ownership, which won’t put the name of the applicant with the poorest credit on the loan but will grant them legal ownership of the property alongside the other borrower(s) involved.

How joint mortgage preapproval works

A joint mortgage preapproval functions just like a standard preapproval, but it involves consolidating financial documents from everyone applying. During this phase, all co–borrowers submit their W–2s, 1099s, bank statements, and tax returns to the lender.

The lender will run a credit check on everyone to verify your group's combined purchasing power. A joint preapproval is a critical step because it provides a realistic budget before you start touring homes. It also signals to sellers and real estate agents that your group has the financial backing to follow through on a purchase offer, possibly giving you an edge.

How much can you buy with a joint mortgage?

The amount you can borrow depends heavily on your combined debt–to–income ratio (DTI). DTI is a simple calculation that compares your total monthly debt payments to your gross monthly income. By pooling multiple incomes together, your overall gross income increases significantly, which usually lowers your DTI percentage.

This drop in DTI allows the group to cross lender qualification thresholds for much larger loan amounts than you could ever qualify for alone. To see how combining your finances impacts your budget, it's wise to use a mortgage calculator. By plugging in your combined incomes and expected monthly debts, you can get a solid estimate of your purchasing power before submitting an official application.

Joint mortgage requirements

To qualify for a joint mortgage, you’ll need to meet the same requirements as any other type of borrower. That means you’ll want at least a decent credit score and minimal debt across the entire group.

For conventional conforming mortgage loan qualification, you’ll generally need:

• A debt–to–income ratio (DTI) no higher than 50%
• A down payment of at least 3% of the purchase price as a first–time home buyer²
• Steady income and stable job security
• A loan amount within the conforming loan limits for your area, as set by the Federal Housing Finance Agency (FHFA)

When exploring government–backed loans, be aware that of the major mortgage investors, only the Federal Housing Administration (FHA) imposes a minimum credit score of 500 with 10% down or 580 with 3.5% down.³

However, lenders may set their own requirements. For example, Rocket Mortgage requires a minimum credit score of 580 on both FHA and VA loans.⁴ Generally speaking, higher credit scores mean qualifying for more loan options and better interest rates.

Rights and responsibilities on a joint mortgage

A joint mortgage is a legal commitment. It’s essential to understand the potential scenarios and responsibilities that come with sharing a loan, as your financial future is directly tied to the actions of your co–borrowers.

If a co–borrower stops paying

Be aware that if someone stops making their share of the payments, the lender can penalize and come after any of the borrowers for the money, since they’re all equally responsible. In the eyes of the lender, there is no such thing as paying "your half" – they demand 100% of the payment on time, every time.

There are several severe risks involved here. If your co–borrower stops contributing and you cannot cover the shortfall, your mortgage will go into default. This carries the risk of foreclosure and will damage the credit scores of everyone listed on the note.

If a co–borrower wants to sell

The legal owner of a property can force a sale – even if the other party responsible for the loan doesn’t agree – if their name is the one on the deed. Although a joint mortgage means two or more parties are responsible for the loan, one person from the pair or group can legally hold ownership of the property by themselves.

If both parties are on the deed and there is a disagreement about selling, the situation can escalate quickly. One party can file a partition action in court to try to force a sale of the property. These lawsuits are incredibly expensive and can drag on for months or years, which is why having a clear, written agreement regarding property sales is so critical before closing.

If a co–borrower passes away

If a co–borrower passes away, the responsibility for the entire loan falls to the surviving borrower(s). The debt does not disappear, and the lender will continue to expect the full monthly payment.

What happens to the actual property depends entirely on how the deed was titled. If the co–borrowers were listed as joint tenants with the right of survivorship, ownership seamlessly passes to the surviving owner. If they were tenants in common, the deceased party's share of the home could pass to a family member or heir through a will, potentially forcing the surviving borrower to co–own the home with a stranger.

If you break up or divorce

A relationship ending doesn’t alter your mortgage contract. If you break up or get divorced, both parties remain fully responsible for the loan until the debt is paid off or refinanced.

Often, a clause in the separation agreement or divorce decree might be that a person has to refinance within a certain amount of time.

However, if the person keeping the home cannot qualify for a refinance on their own, the couple is usually forced to sell the home to satisfy the remaining mortgage debt.

Pros of a joint mortgage

So, why would you want to get a joint mortgage loan versus a loan with only your name on it? Here are a few of the biggest benefits of a joint mortgage.

Increased buying power

With a joint mortgage, you get the chance to pool your income with another person’s or that of several people. This may allow you to pursue homes that would otherwise be out of your price range. Having two incomes on a mortgage application means you’ll likely be able to qualify for a larger loan. This is especially helpful in the current housing market, where prices remain expensive.

Easier loan qualification

Truth is, applying for a mortgage loan with others who may have more income or better credit can help you get a loan that you might not otherwise be able to qualify for on your own. Pooling with co–borrowers can also lead to more favorable loan terms.

“Putting together income and assets can help borrowers get bigger loans or lower interest rates. This is especially important in today’s housing market, where prices are high,” Shirshikov says. “When two or more people apply together, they usually have lower DTI ratios and are more likely to get approved, which can lead to better fee structures and prices.”

Potentially more affordable homeownership

Having two or more people responsible for the mortgage payments and other costs associated with owning a home can reduce the financial burden and make homeownership more affordable and easier to budget. Sharing the upfront costs – like the down payment, closing costs, and moving expenses – makes a significant difference. You can use Rocket Mortgage’s affordability calculator to see what you may qualify for.

However, simply being on a joint mortgage with someone doesn’t ensure that they’ll faithfully contribute to maintenance costs – or even the mortgage payment they’ve agreed to make in part. It allows the lender to hold them accountable if the mortgage payments aren’t being made. For joint ownership to work, the other borrower must pay and share costs as agreed.

Building equity together

This is a vehicle for a joint mortgage first–time buyer to enter the housing market. Instead of waiting years to save enough money individually, co–borrowers can jump into homeownership sooner. This allows them to begin building home equity together, growing their wealth as property values appreciate and the loan principal gets paid down over time.

Cons of a joint mortgage loan

Combining resources with friends, family members, or partners can open doors for you to get a mortgage. But it can also create complications. Here are a few of the downsides of getting a joint mortgage loan.

Full responsibility for payments

If the other borrower on your loan can’t afford their half of the payment or just chooses not to pay as planned, you may be held responsible for the entire mortgage payment – and their inability or refusal to pay will impact your credit and finances. If a co–borrower passes away, the responsibility for the entire loan falls to you and anyone else who’s responsible for paying the joint mortgage.

With this in mind, you choose to have a co–borrower just because you might be able to afford a more expensive home with their help. Before agreeing to any loan, you should always research how much house you can afford and discuss all possible outcomes with your co–applicant(s) and lender in advance.

Impact on future borrowing

One of the biggest hidden drawbacks is how a joint mortgage impacts your future borrowing capabilities. When you have a joint mortgage, the full amount of the monthly mortgage payment counts against your individual DTI, even if you personally only pay half of it.

Because this massive debt is tied to your name, it can make it significantly harder for you to get approved for an auto loan, personal loan, or another mortgage on your own in the future.

Potential legal complications

As mentioned, all parties on a joint mortgage don’t necessarily own equal shares of the property. Unless they’re joint tenants and/or have full joint ownership, only one of the borrowers in a joint mortgage may have their name on the actual property deed.

“When co–borrowers clash over who owns what or who should pay what, the conflict can spill into the legal system. Having a written agreement is better than a stranger deciding," says Ailion. “In past cases, courts have dealt with matters like partition actions to force a property sale, lawsuits seeking repayment from a co–owner and claims for a constructive trust. Such disputes often drag on and rack up significant legal expenses.”

It’s a good idea to speak to an attorney to better understand your property rights.

Is a joint mortgage right for you?

Entering a 30–year financial contract with another person is a massive decision. You must objectively evaluate whether your partnership is likely to be long term.

Who may be a good candidate for a joint mortgage

Married couples and domestic partners who share the same long–term goals are often the best candidates for co–borrowing on a mortgage loan. That’s also true of parents who co–sign to help their kids get better rates.

“When close family members pool their money, like when siblings purchase a vacation home together, they can also benefit – especially if they do it through an LLC with an operating agreement,” says Shirshikov.

Worthy prospects for joint mortgages also include those with compatible credit profiles who can communicate well together and have a plan for what to do if things change in the future. For example, buying a house with a friend can be a fantastic way to afford a better property, provided you have absolute trust in their financial reliability.

“Roommates and business partners can also be good candidates, but they must have strong trust in a written agreement detailing exit procedures, contribution expectations, and conflict resolution,” Ailion says. “Face it: People change, often for the worse. One of the toughest questions to answer is, ‘Why didn’t you recognize that behavior before you locked into the mortgage together?’”

Who may not be a good candidate for a joint mortgage

You are likely not a good candidate for a joint mortgage if you are considering applying with someone who has a history of maxed–out credit cards, hiding debt, or missing payments. If your relationship is rocky, or if you struggle to have calm, transparent conversations about money, a joint mortgage will likely only amplify those issues.

Furthermore, if you or your co–borrower refuses to put your agreements regarding payments and exit strategies in writing, you should avoid the commitment altogether.

How to get a joint mortgage

If you’ve carefully considered the benefits and drawbacks of a joint mortgage and are ready to move forward with applying for a mortgage, here are the steps you’ll need to take to learn how to apply for a joint mortgage.

Figure out your finances

Before you approach a lender, sit down with your co–borrowers and have an honest conversation about your finances. Pull your credit reports, calculate your combined gross monthly income, and review your existing debts to get a realistic picture of your combined financial health.

Find a lender and get preapproved

When taking out a joint mortgage, start by comparing lenders to see which one will offer you the best loan conditions. You’ll also want to carefully consider the types of mortgages available to you and determine which option is the best fit in the mortgage loan process before you get preapproved.

With a Verified Approval, Rocket Mortgage allows you to get your credit pulled while having income and assets shared so that you and the seller can be confident in your offer.⁵

Apply and provide documentation

Once you’ve chosen the lender and type of joint mortgage you want, you can fill out and submit your initial loan application. You can often complete this process online.

As part of the underwriting process, your lender will ask for documentation from every borrower. You’ll need to gather recent pay stubs, W–2s, 1099s, bank statements, and Social Security or disability award letters to verify your finances. Returning these documents quickly helps ensure a smooth process.

Close on the loan

If all goes according to plan during the underwriting process, the last step is to close on your loan. All borrowers will need to attend the closing (either in person or online, depending on your state) to sign the required paperwork and disclosures and pay the closing costs and down payment.

How to get out of a joint mortgage

Escaping the legal responsibilities of a joint mortgage typically requires a refinance or home sale to completely sever the financial ties. Here are a few of your options if you want to learn how to get out of a joint mortgage.

Refinance the loan

If you want out of a joint mortgage, first have an honest talk with your co–borrower about your desire. Since this person will likely be a family member or a friend, this conversation can be difficult, but if the other party understands your intentions and reasoning for wanting out, they may be more willing to consider refinancing to remove a name from a mortgage.

To achieve this, the remaining party must refinance the loan entirely in their own name, assuming they qualify independently based on their own credit and income. If you both aren’t willing to refinance, you likely won’t be able to get out of the loan without selling the property. You may also want to consider a cash-out refinance. Be sure to consider the costs to refinance before bringing up this possibility to your co–borrower.⁶

Buy out your partner

If your partner or co–borrower wants out of a joint mortgage, it’s possible to buy them out if all parties agree to it. This means you essentially give your partner(s) their share of the equity through a cash–out refinance.

You’ll need to have some equity built in the home to pull this off successfully, but if it’s an option for you, it can be a way to remove other parties from the loan and refinance to sole ownership.

You’ll be required to have your home appraised as well as determine the equity in the home that belongs to each partner. If you can all agree on a buyout price, you can proceed to refinance and become the sole owner of the mortgage. Keep in mind that you’ll also need to qualify individually for your lender’s requirements on the new loan.

Sell the home

If all parties agree, you can opt to sell the home and move on. Rather than deal with refinancing or having to buy out a co–borrower, selling the home and going separate ways can relieve all parties of the responsibilities of the current joint mortgage loan. The proceeds from the sale are used to pay off the mortgage, and any remaining profit is split.

If one or more of your co–borrowers is attached to the home, however, this option may not be feasible for you. It can be difficult to get everyone to agree to a home sale, as they must give up ownership and residency in the property as well.

“Selling can lead to potential capital gains taxes or fees for paying off the loan ahead of schedule. In most cases, every borrower must agree to the sale – unless a court, as in certain divorce cases, orders otherwise,” says Ailion. "It’s best to resolve a conflict before you have one. Decide in writing well in advance, preferably with an attorney’s assistance, how outcomes are to be resolved. In conflict situations, emotions are raw and hostility is high. Once you reach that point, it’s hard to do what you should and would have agreed to in the beginning.”

FAQ

There are a lot of details to remember when financing a home with someone else. If you’re thinking of taking out a joint mortgage, the answers to some frequently asked questions about this topic may help guide your decision.

What are the disadvantages of a joint mortgage?

The main disadvantage of a joint mortgage is the shared legal liability. You are 100% responsible for the debt even if your co–borrower stops paying. The full mortgage amount counts against your individual DTI, which can make it challenging to borrow money for a car or personal loan in the future. If you ever want off, you have to sell the home or refinance.

Is a joint mortgage a good idea?

A joint mortgage is a brilliant idea if you need to pool incomes to afford a home and you are applying with someone you deeply trust. It makes homeownership much more accessible and allows you to build equity sooner. It can be a bad idea if you have doubts about your co–borrower’s financial reliability or if you fail to establish a written agreement before closing.

Can I afford a $300K house on a $50K salary?

Affording a $300,000 house on an individual $50,000 salary can be very challenging, as the monthly payments would likely push your DTI past standard lender limits. This is where a joint mortgage is incredibly helpful. If you apply with a co–borrower who also makes $50,000, your combined income of $100,000 could make qualifying for that $300K home more realistic.

How much deposit is needed for a joint mortgage?

The required deposit, or down payment, for a joint mortgage is determined by the specific type of loan you choose, not by how many people are on the application. Remember that conventional loans may require as little as 3% down, FHA loans require at least 3.5% down, and VA loans often require 0% down. You and your co–borrowers can split this cost as you see fit.

Can you add someone to a joint mortgage later?

It's typically not possible to add a new borrower to an existing mortgage without refinancing. The lender originally underwrote the loan based on specific risks, and they will not simply insert a new party onto the promissory note. You usually have to completely refinance the loan. However, someone may be added to the property deed via a quitclaim or warranty deed.

Can an unmarried couple buy a house together?

Yes, an unmarried couple can purchase a house together. You don’t have to be married to someone to buy a house with them or get a joint mortgage. However, unmarried couples should consult an attorney and/or financial adviser about their situation before moving forward.

Also, this shouldn’t be the first conversation you have about finances. The parties should feel comfortable going into the agreement with each other. Be sure to review the unique questions unmarried couples should consider when buying a house so you are both fully prepared for the commitment. You should also consider what will happen to the mortgage if someone dies.

How does a joint mortgage affect tax benefits?

As with most mortgage loans, you can typically deduct mortgage interest – and some other fees – if you itemize deductions when filing your taxes, rather than taking the standard deduction. Typically, the person who actually paid the interest and property taxes is the one entitled to deduct the expenses on their report.

If both you and your spouse or another co–borrower paid a share of the interest or property taxes, you’ll want to attach an explanation of that and how much you each paid to your return. This isn’t a problem for married couples who file jointly.

Because tax laws can be extremely complicated, you should always consult a tax professional for guidance specific to your situation.

The bottom line: A joint mortgage can help, but know the risks

Buying a home with a partner, friend, or family member can be an exciting journey that jump–starts your path to building wealth. Getting a joint mortgage makes homeownership more affordable and increases your buying power, allowing you to pool your resources to afford a home you truly love.

Since two or more people are equally responsible for making payments, however, some complications can arise with a joint mortgage – particularly if you ever want to get out of the arrangement. It's crucial to have open conversations about money, understand the credit risks, and put a solid agreement in writing before you take the leap.
