If you’re buying a home with family, friends, or a partner, you may be asking: how many people can be on a mortgage? Whether you’re purchasing a multi-generational property, investing with others, or splitting housing costs, joint home loans can make homeownership more affordable. However, mortgage lenders set clear limits and requirements you should understand before applying.

Is There a Limit to the Number of Mortgage Co-Borrowers?

Legally, there is no set limit on how many co-borrowers can apply for a mortgage. However, most conventional loan lenders cap the number of borrowers at four, particularly when the loan is backed by Fannie Mae or Freddie Mac.

This restriction exists due to automated underwriting systems like Fannie Mae’s Desktop Underwriter, which can process a maximum of four applicants. More than four requires manual underwriting, and many lenders no longer support that process.

What Is a Co-Borrower?

A co-borrower is someone who shares responsibility for the mortgage loan. Their name appears on the loan and property title, and they contribute to qualifying income, down payment, and monthly payments.

Examples of Co-Borrowers Include:

Relationship	Scenario
Married or unmarried couples	Buying a primary residence together
Parents and adult children	Co-owning a multigenerational home
Friends or business partners	Purchasing an investment property jointly
Siblings or extended family	Sharing housing costs or buying as a family group

Loan Program Rules for Co-Borrowers

Different loan types have different guidelines when it comes to co-borrowers. Here’s what to expect in 2025:

Loan Type	Co-Borrower Guidelines
Conventional	Allows up to four co-borrowers; non-occupant co-borrowers are permitted
FHA	Non-occupant co-borrowers are allowed, but stricter rules apply if not a family member
VA	Must be a spouse or another VA-eligible borrower unless applying jointly with VA approval
USDA	Only occupant co-borrowers are allowed; no non-occupants permitted

Each co-borrower must submit a full mortgage application, credit report authorization, income documentation, and employment history.

Should You Buy a Home With Multiple People?

Buying a home with others can improve affordability and increase buying power. However, it also adds legal and financial complexity. If you’re entering a co-ownership arrangement with people outside your household, consider establishing a legal agreement to define each person’s responsibilities.

Smart Steps for Joint Buyers:

• Draft a co-ownership agreement with the help of a real estate attorney.
• Clarify who contributes to payments, how equity is divided, and what happens if someone wants out.
• Check with your lender about ownership structures like LLCs or trusts, as not all lenders allow them.

How to Remove a Co-Borrower From a Mortgage

Removing someone from a mortgage later requires careful planning. Most commonly, borrowers use one of these methods:

Option	Details
Refinancing	One borrower refinances the loan into their name (must qualify independently)
Selling the Property	The home is sold, and proceeds are split among co-borrowers
Loan Assumption	If allowed by the lender, one person may assume the loan and take full liability

Removing someone from the mortgage does not automatically release them from liability—lender approval is required.

Bottom Line

Buying a home with multiple people can be a smart financial strategy—but it’s important to go in with a clear understanding of each co-borrower’s role and responsibilities. From loan eligibility and credit requirements to legal agreements and long-term plans, every detail matters when you share ownership.

By choosing the right loan program, working with a knowledgeable lender, and creating a solid co-ownership agreement, you can confidently move forward with your home purchase. Ready to explore your options? Loan Pronto is here to help guide you through every step of the joint mortgage process.
