Can You Buy a House With a Friend or Partner If You're Not Married?

You've got a good friend — or a partner you've been with for years — and you're both tired of paying rent. You start running the numbers together, and suddenly the idea comes up: What if we just buy a house together? It's a smart question. And one I hear more often than you'd think.

The short answer is yes — you absolutely can buy a house with someone you're not married to. Whether that's a romantic partner, a best friend, a sibling, or a business partner, the mortgage process doesn't require a marriage certificate. What it does require is a clear understanding of how it works, because the rules are a little different than when a married couple buys together.

Let me walk you through what you need to know before you move forward — the good and the honest.

Can Two Unmarried People Apply for a Mortgage Together?

Yes, and lenders do it all the time. This is called a joint mortgage or co-borrower arrangement. Both people apply together, both incomes count, and both credit scores are evaluated.

Here's the important part: lenders typically use the lower of the two middle credit scores to qualify. So if your score is 720 and your friend's is 630, the lender is likely pricing your loan closer to that 630. That can affect your interest rate — sometimes significantly.

• Both borrowers are equally responsible for the full loan amount
• Both names go on the mortgage
• Late payments affect both credit profiles
• If one person stops paying, the other is still 100% on the hook

That last point is the one I always make sure my clients understand before they sign anything.

How Is the Down Payment and Ownership Split?

This is where things get flexible — but also where things can get complicated if you don't plan ahead.

Let's say you and a partner are buying a $320,000 home with a conventional loan at 10% down. That's $32,000 upfront, plus closing costs of roughly $6,000–$8,000. You might split that 50/50, or one person might put in more and want a larger ownership share.

Here's the thing: the mortgage doesn't define your ownership split — the title does. You can hold the property as:

• Joint Tenants with Right of Survivorship — equal ownership; if one person dies, the other inherits automatically
• Tenants in Common — each person owns a defined percentage (e.g., 60/40), and can leave their share to whoever they choose in a will

I always recommend talking to a real estate attorney before closing to decide which option fits your situation. This is especially important if one person is putting in significantly more money.

What Happens If One of You Wants Out?

This is the conversation nobody wants to have before buying — but the one you need to have.

If the relationship changes (romantic or otherwise), you have a few options:

• One person buys out the other by refinancing the loan into their name alone
• You sell the home and split the proceeds based on your ownership agreement
• You both agree to keep it as a rental or investment property

A buyout requires the remaining person to qualify for the mortgage solo. If a $320,000 home has appreciated to $370,000 and you each own 50%, the buyout figure would be roughly $185,000 in equity — on top of refinancing the remaining loan balance.

Without a written agreement upfront, these situations can turn into expensive legal headaches. A simple co-ownership agreement drafted by an attorney (usually $500–$1,500) can save you tens of thousands down the road.

Do You Need to Be a U.S. Citizen or Have a Certain Immigration Status?

Not necessarily. I work with buyers across all kinds of immigration situations, and there are loan options available for ITIN holders, permanent residents, and more. Your citizenship status doesn't automatically disqualify you from buying a home — with or without a co-borrower.

Next Steps: Talk It Through Before You Sign Anything

Buying a home with a friend or unmarried partner is absolutely possible — and for a lot of people, it's a smart financial move. Two incomes, shared costs, and building equity together instead of paying someone else's mortgage.

But go in with your eyes open. Talk about the what-ifs before you close. Get a co-ownership agreement in writing. And make sure both of your financial profiles are ready.
