Buying With Others
What should you know before buying a home with a partner, friend, or family member?
The short answer
Co-buying means two or more people purchase a home together, and it splits into two separate questions that people often confuse: who is on the loan, and who is on the title. Everyone on the loan is fully responsible for the entire mortgage — not just their share — and a lender evaluates the group’s combined income, debts, and the lowest applicant’s credit. Everyone on the title owns the home, in a share and structure set by the deed. Because these can be decided independently, and because splitting up later is far harder than splitting up a lease, the decisions worth making before you buy are how you’ll hold title, how you’ll split costs, and what happens if one person wants out.
Key points
- Being on the loan and being on the title are separate decisions.
- Every co-borrower is liable for the full mortgage, not a share of it.
- Lenders often price off the lowest applicant’s credit score.
- The hardest part to undo is ownership — plan the exit before you buy.
Loan vs. title
A co-borrower signs the mortgage and is legally responsible for repaying all of it; if one person stops paying, the others owe the full amount and everyone’s credit is affected. A co-owner is named on the deed and owns a share of the property. You can be on both, on only the title, or (less commonly) on only the loan — and each combination has different consequences for liability, credit, and what happens in a breakup or death.
What a lender looks at
Lenders combine the applicants’ incomes and debts into shared debt-to-income ratios, which can raise buying power — but they also weigh the lowest middle credit score among applicants, so one person’s thin or damaged credit can raise the rate for everyone. Fair-lending rules bar a lender from discouraging a qualified co-applicant, but they do not change how the numbers combine.
Common questions
- Do co-buyers have to be married or related?
- No. Any two or more people can buy together — partners, friends, siblings, or a parent and adult child. A large and growing share of buyers co-purchase with a non-spouse.
