How Many People Can Be on a Mortgage?

As home prices hit another record high, steadily rising, more people are teaming up to afford a house, whether it’s couples, friends, siblings, or even adult children and parents. Co-buying is becoming more common, but it raises a key question: How many people can actually be on a mortgage?

Quick answer: There’s no legal limit on how many people can be on a mortgage, but most lenders allow up to four. That’s because standard underwriting systems can only handle four applicants—anything more typically requires manual review.

Whether you’re co-purchasing a townhome in Seattle, WA or a house in Boston, MA,  joint mortgages allow you to split a loan with someone else to help make homeownership more affordable. 

This Redfin guide will walk you through the essentials of a joint mortgage and what to know before signing the dotted line. 

How many people can be on a mortgage?

There’s no legal limit to how many people can be on a mortgage, but most lenders will allow up to four borrowers on a single home loan. Some may allow more, but this depends on their internal policies. Often the mortgage underwriting software they use, such as Fannie Mae’s Desktop Underwriter or Freddie Mac’s Loan Product Advisor, typically caps applications at four individuals.

When multiple people apply for a mortgage together and share both the financial responsibility and legal ownership of the home, it’s called a joint mortgage. This type of arrangement allows co-borrowers to combine their income and credit profiles, which can help with loan approval or boost purchasing power.

That said, just because several people can apply doesn’t mean they’ll all qualify. Lenders assess each applicant’s income, credit score, debt-to-income ratio, and employment history. The lowest credit score in the group can affect the loan terms, so one weaker profile may influence the entire application.

How do you apply for a mortgage with multiple borrowers?

If your lender and loan type allow co-borrowers, each person will fill out their own application and provide proof of income, assets, debts, and employment. Everyone will have a credit check, and all co-borrowers need to be present together at closing.

What do lenders look at with multiple co-borrower applicants?

When multiple people apply for a mortgage together, lenders evaluate everyone’s finances but often base the loan terms on the lowest credit score among the group. They’ll examine:

• Credit reports and scores for each applicant






• Proof of income (pay stubs, W-2s, tax returns)






• Debt-to-income ratios






• Employment history and stability






• Cash reserves or savings

All of this affects how much you can borrow and what kind of interest rate you’ll get. If one borrower has poor credit or high debt, it could limit your options or mean higher interest rates for everyone.

Why do multiple people get a mortgage together?

Buying a home solo can be financially tough, especially in competitive markets with high prices and tight inventory. That’s why many buyers are turning to co-ownership as a practical solution. Here are a few common scenarios:

• Unmarried couples want to purchase a home together.






• Siblings or friends team up to buy a starter home or investment property.






• Parents co-buy with their adult children to help them enter the housing market.






• Business partners co-invest in a multi-unit or rental property.

In these cases, pooling financial resources can increase buying power, making it easier to qualify for a loan or afford a better property.

Co-Borrowers vs. co-signers vs. joint mortgages: what’s the difference?

When applying with others, it’s important to understand the difference between co-borrowers, co-signers, and joint mortgages, as they’re not the same.

• Co-borrowers are equal partners on the mortgage and the property title. They’re jointly responsible for monthly payments and have ownership rights. 






• Co-signers don’t have ownership interest in the property but help someone qualify by backing the loan with their income and credit. They’re financially liable but not on the deed.






• Joint mortgages is the loan structure when two or more co-borrowers apply together. It’s the setup that allows all parties to share the mortgage obligation and own the home jointly.

So, if your name is on the mortgage and the deed, you’re a co-borrower on a joint mortgage. If you’re just helping someone qualify without sharing ownership, you’re a co-signer.

Pros and cons of having multiple co-borrowers

Teaming up with others has clear upsides, but there are also risks. Here’s what to keep in mind.

Pros:

• Higher buying power: Combined incomes can help qualify for larger loans.






• Shared costs: Mortgage payments, taxes, and maintenance can be split.






• Easier approval: If one borrower has strong credit and income, it can help offset another’s weaker profile.

Cons:

• Shared liability: Everyone on the mortgage is fully responsible for repaying the loan. If one borrower stops paying, the others must cover the full amount. Lenders can go after any co-borrower for the total balance due.






• Credit risk: Missed payments affect all borrowers’ credit scores.






• Potential disputes: Decisions about selling, refinancing, or maintenance must be made jointly.

Make sure you trust your co-borrowers, and talk through expectations up front to avoid conflict later.

Tips when buying a home with multiple people

Buying a home with others can work well, but it’s important to plan ahead. Here are some practical tips:

• Check with lenders early: Not all lenders allow more than two borrowers, and some may have stricter credit or income requirements for joint applicants.






• Get preapproved as a group: A joint preapproval will give you a clearer idea of your combined buying power and help identify any credit or income concerns upfront.






• Consult a real estate attorney: A lawyer can help you draft a co-ownership agreement and explain your legal obligations and ownership options.






• Choose the right ownership structure: Decide whether to hold the title as joint tenants or tenants in common; each has different legal and inheritance implications.






• Have a written agreement: A co-ownership contract should outline who pays what, how ownership is divided, and what happens if someone wants out.






• Create an exit plan: Agree in advance on how you’ll handle refinancing, selling, or buying someone out if circumstances change.






• Consider opening a shared bank account: A joint account can simplify making mortgage payments and tracking shared expenses.






• Be honest about financial history: Everyone’s credit, debt, and income will be scrutinized; transparency will prevent surprises during underwriting.

How do you get out of a joint mortgage?

When multiple people share a mortgage, life changes (like a breakup, divorce, job relocation, or disagreement) can make it necessary for one or more borrowers to exit the arrangement. However, getting out of a joint mortgage isn’t always simple. Whether you want to leave or need to remove someone else, here’s what to know:

1. Refinance the mortgage

The most common way to get out of a joint mortgage is through refinancing. This means one borrower applies for a new loan in their name only (or with a new co-borrower), paying off the original joint mortgage in the process.

However, this only works if the remaining borrower qualifies on their own; their income, credit, and debt-to-income ratio must meet the lender’s standards.

2. Sell the home

Sometimes the cleanest way to dissolve a joint mortgage is to sell the property and split the proceeds. This is helpful if no one can afford to take over the mortgage solo or if both parties want a fresh start. After selling, the mortgage is paid off and all parties are released from responsibility.

3. Loan assumption (rare, but possible)

In limited cases, a lender may allow the remaining borrower to assume the mortgage, meaning they take over the loan under its existing terms. This can avoid refinancing, but it usually requires requalification and lender approval, which isn’t guaranteed.

4. Legal action or buyout agreements

If one borrower refuses to cooperate, the other may need to take legal action to force the sale of the home or agree to a formal buyout, where one party pays the other for their share of the home’s equity. These situations often require help from a real estate attorney.

Important: Removing a name from the mortgage does not automatically remove someone from the deed (ownership title), and vice versa. You’ll need to file a quitclaim deed or other title transfer form to fully change ownership records.

FAQs

Can a joint mortgage be transferred to one person?

Not directly. To transfer a joint mortgage to one person, the remaining borrower typically needs to refinance the loan in their name only, which requires qualifying on their own. Simply removing a name without refinancing is rarely allowed by lenders.

What is the maximum number of people on a mortgage?

Most lenders allow up to four borrowers on a single mortgage, though this can vary. While there’s technically no legal limit, lenders set their own policies based on underwriting systems, and all applicants must meet credit and income requirements.
