Dear Claire: What’s the Difference Between Buying a Home as a Married Couple vs. a Non-Married Couple?

Dear Claire, My partner and I want to buy a home together, but we are not married. Does that make the process different? Would it be easier or safer to wait until after we’re married?

Buying a home with another person is a major commitment, whether that person is your spouse, romantic partner, family member, or friend.

The basic home-buying process does not suddenly become unavailable because you are unmarried. Two unmarried people can apply for financing together, own a property together, share expenses, build equity, and eventually sell the home.

The biggest difference is not necessarily what happens while everything is going well. The biggest difference is what happens if the relationship changes, one person wants to sell, someone stops contributing, or one owner dies. (Sorry to be a bummer here.)

Marriage comes with an existing legal framework that addresses property, inheritance, separation, and divorce. Unmarried co-owners generally do not have those same built-in protections. That does not mean unmarried couples should not buy homes together. It means they should create their own structure before the purchase is complete.

This is one of those subjects where a real estate agent, lender, attorney, estate-planning professional, and tax adviser may all have a role.

My job is to help buyers recognize the questions early enough to get good answers before they sign documents and take on a 30-year financial obligation together.

Can Unmarried Couples Buy a Home Together?

Short answer: Yes.

You do not need to be married or even romantically involved to purchase property with someone else. Friends can buy a home together. Siblings can purchase a property together. Parents and adult children can become co-owners. Business partners can jointly acquire real estate. A romantic couple can buy a house before deciding whether marriage is part of their future.

The lender will care about each borrower’s income, assets, debts, credit profile, and ability to repay the loan. The title company will care about how the buyers intend to hold ownership. Neither one requires buyers to be married simply because they are purchasing the same home.

However, being allowed to buy together is not the same as being prepared to own together.

Marriage Provides a Legal Process for Untangling Assets

Suppose a married couple purchases a home and later decides to divorce. That does not mean dividing the home will be easy, pleasant, or inexpensive. It does mean there is a formal legal process for addressing marital property, debt, and other financial obligations.

The spouses may negotiate a settlement, sell the home, refinance it into one person’s name, or ask a court to decide how the property should be handled.

Now imagine an unmarried couple who purchase a home and then decide to separate several years later.

There is no divorce proceeding automatically waiting to divide the property. Both people may remain owners. Both may remain responsible for the mortgage.

One may want to sell while the other refuses. One may move out while continuing to owe money on a home they no longer use. Without a written agreement, those former partners may have to negotiate from scratch or pursue a civil legal remedy.

That is why I often tell unmarried buyers that an ownership agreement should be created while they still like and trust each other. It is much easier to agree on a fair process before anyone is hurt, angry, financially stressed, or trying to leave.

Buying Before Marriage Can Offer Flexibility

Although unmarried ownership requires more planning, it can also provide flexibility. Not every couple arrives at a home purchase with equal financial resources. Perhaps one person has excellent credit but limited savings. The other person may have enough money for most of the down payment, but a weaker credit profile.

One buyer may contribute 75% of the upfront cash while the other contributes 25%. Perhaps one person will pay more of the monthly mortgage because their income is higher, while the other agrees to manage improvements or contribute in another way.

These arrangements do not have to be identical. They do need to be clearly understood and documented. People sometimes assume that putting unequal amounts into the purchase automatically creates unequal ownership. That is not something I would leave to assumption.

The deed, any co-ownership agreement, loan documents, and financial records all matter. Buyers should work with an attorney to make sure the legal structure reflects what they actually intend.

The Mortgage and the Deed Are Different

This distinction is incredibly important.

The mortgage loan establishes who is responsible for repaying the borrowed money.

The deed establishes who owns the real estate.

Those are related, but they are not the same thing. Someone can potentially be on the deed without being a borrower on the mortgage, subject to lender requirements and other legal considerations. Someone may also be obligated on a loan while ownership changes later, although changing title does not automatically remove that person from the debt.

Let’s say I qualify for a mortgage by myself and purchase the home in my name. After closing, I cannot simply assume that adding another person to the deed is a casual administrative step. The loan documents, lender rules, taxes, ownership consequences, estate planning, and possible transfer issues need to be considered first.

Likewise, if two people sign the mortgage and one later signs over their ownership interest, that person may still be legally responsible for the loan until the mortgage is refinanced, paid off, or otherwise formally changed.

You cannot remove yourself from mortgage liability merely by moving out or signing a private agreement with the other owner. The lender is not required to honor a personal promise that says, “My former partner will make the payments from now on.”

As far as the lender is concerned, the borrowers who signed the loan remain responsible unless the lender agrees to a formal change.

Do Lenders Average Both Credit Scores?

This is an area where mortgage rules have changed and also vary by loan type and underwriting system. People often hear that a lender simply takes the lowest score of everyone applying. That can be true in some mortgage calculations, but it is not a complete explanation of current underwriting.

A lender obtains credit information for each borrower and evaluates the complete application, including income, debt, assets, credit history, occupancy, loan type, and property. Under current Fannie Mae rules, each borrower has an individual representative credit score, while certain loan-eligibility calculations for multiple borrowers use an average median credit score. Other underwriting decisions and loan programs may use credit information differently.

The practical point is that adding a second borrower does not automatically make an application stronger. A second person may bring valuable income and assets, but they may also bring substantial debts or credit problems.

Sometimes two people qualify more comfortably together. Sometimes one person qualifies for better terms alone. And, just because you are married does not mean you must automatically apply for the mortgage together. Unmarried couples also do not have to submit a joint application merely because both people intend to live in the home.

A good lender can compare different structures and explain:

• Whether one or both people should apply
• How each person’s income will be treated
• How debts affect qualification
• Which credit scores apply
• Whether both buyers can be on the deed
• What down payment and reserve requirements apply
• How the ownership structure may affect the loan

Do this analysis before you begin writing offers. You do not want to discover halfway through a transaction that your assumed financing structure does not work.

How Should Two People Hold Title?

This is where buyers need legal advice specific to their situation.

In Oregon, co-owners may hold real property through different forms of ownership, including tenancy in common and ownership with survivorship rights. Married couples may also have ownership options associated with their marital status. The wording of the deed matters because it can affect each owner’s interest and what happens after a death.

The old blog framed tenants in common as the form most buyers will automatically use. I would not make that assumption. Instead, buyers should deliberately select the ownership form that reflects their intentions.

Tenants in common

Tenants in common can own different percentages of the property.

For example:

• One owner could hold 75%
• The other could hold 25%

Each owner’s interest is generally separate. When one owner dies, that interest does not necessarily pass automatically to the other co-owner. It may pass according to a will, trust, or Oregon inheritance law.

This can make sense when buyers contribute unequal amounts or want their ownership interest to pass to someone other than the co-owner.

Ownership with a right of survivorship

A survivorship structure is intended to allow a deceased owner’s interest to pass to the surviving owner or owners rather than through the ordinary probate process. This may be exactly what an unmarried couple wants. It may also be exactly what they do not want.

For example, perhaps I own a home with my partner, but I want my interest to eventually benefit my child, sibling, niece, or another family member. A survivorship deed could conflict with that plan.

This is why no one should select a title option merely because it sounds familiar or appears on a standard form. The deed should coordinate with the owners’ estate plans.

What Happens If One Owner Dies?

This is an uncomfortable conversation, especially for young buyers who feel as though death is too remote to think about. Unfortunately, avoiding the subject does not prevent it from becoming important. Hope for the best, plan for the worst.

Suppose two unmarried partners own a house together and one dies unexpectedly.

What happens next may depend on:

• The wording of the deed
• Whether there is a right of survivorship
• Whether the deceased person had a will or trust
• Whether there are children or other heirs
• How the mortgage is structured
• Oregon probate and inheritance laws
• Any written co-ownership agreement

If the deceased owner’s interest passes to a family member rather than the surviving partner, the surviving owner could suddenly co-own the property with the deceased person’s heir.

That heir might want to sell. The surviving partner might want to stay. Neither person may have expected to be in business with the other.

Married couples may have certain inheritance rights under state law, but even married homeowners should not assume the default result matches their wishes. Blended families, children from prior relationships, separate property, trusts, and existing estate plans can make the outcome more complicated.

Everyone buying property with another person should consider wills, trusts, powers of attorney, beneficiary planning, and appropriate life insurance.

Unmarried Buyers Need a Co-Ownership Agreement

A deed identifies ownership, but it usually does not answer every practical question about living in and paying for the property. That is where a co-ownership agreement can be extremely valuable.

An attorney can help the buyers address issues such as:

• How much each person contributes to the down payment
• Each person’s ownership percentage
• Who pays the mortgage
• How taxes, insurance, and utilities are divided
• Who pays for repairs and improvements
• Whether one owner receives credit for paying more
• How renovation decisions will be made
• Whether either owner may rent out part of the home
• What happens if one person stops paying
• What happens if the relationship ends
• Whether one owner has the first opportunity to buy out the other
• How the buyout price will be determined
• What happens if neither person can afford a buyout
• When the home must be sold
• How sale proceeds will be divided
• How disputes will be resolved
• What happens after death or incapacity

A verbal understanding such as “We’ll split everything fairly” is not enough. People can have completely different definitions of fair. Suppose one owner contributed the entire down payment, but both made equal mortgage payments for ten years.

Should the first owner receive the original down payment back before the remaining equity is divided? Suppose one person paid $100,000 for a major remodel. Does that change ownership percentages, or was it simply a contribution to a jointly owned asset?

Suppose one owner stops paying for six months. Does the other owner’s additional contribution become a loan, additional equity, or neither?

These questions are difficult enough when everyone is cooperative. They become much harder after a breakup.

Married Couples Should Have These Conversations Too

Marriage provides a legal structure, but it does not eliminate the need for planning. Spouses may enter a marriage with different amounts of savings, separate property, children from prior relationships, family gifts, inheritances, or existing real estate.

One spouse may provide the entire down payment from funds accumulated before the marriage. A parent may give money specifically to one spouse. One person may buy the home alone, even though both will live there.

Those facts may have legal and tax consequences. Married buyers may want to speak with an attorney about:

• Prenuptial or postnuptial agreements
• Separate versus marital property
• How title should be held
• Estate planning
• Children from prior relationships
• Contributions from family members
• What happens if one spouse dies
• What happens if the marriage ends

Marriage reduces some uncertainty, but it does not guarantee that every default legal rule matches your personal goals.

How Are Mortgage Interest and Property-Tax Deductions Divided?

Taxes are another area where buyers should avoid casual assumptions.

The person named on the Form 1098 is not necessarily the only person who could ever qualify to deduct mortgage interest. The deduction depends on factors such as legal responsibility for the debt, ownership, whether the debt is secured by a qualified home, who actually paid the expense, filing status, and whether the taxpayer itemizes deductions.

The IRS gives an example in which unmarried housemates who each paid half of the mortgage interest and property taxes each deducted their respective half. That does not mean every pair of owners should simply divide deductions however they prefer.

Your accountant will need to review:

• Who owns the property
• Who is liable for the mortgage
• Who made the payments
• Whether payments came from a joint account
• Whether each person itemizes
• The applicable mortgage-debt limitations
• Each person’s filing status

Married couples filing separately also have special rules. For example, if one spouse itemizes, the other spouse generally must itemize as well.

Keep good records.

If two unmarried owners are splitting payments, document who paid what rather than trying to reconstruct several years of contributions when the property is sold or a tax question arises.

What Is the Principal Residence Gain Exclusion?

This is one of the most valuable tax benefits associated with owning and living in a primary residence.

Generally, an individual may exclude up to $250,000 of qualifying gain from the sale of a principal residence. A married couple filing jointly may qualify to exclude up to $500,000 if the applicable requirements are satisfied.

The basic qualification rules generally require the taxpayer to have:

• Owned the home for at least two years during the five-year period before the sale
• Used the home as a principal residence for at least two years during that same five-year period
• Not used the exclusion on another home sale within the applicable two-year period

There are additional rules and exceptions, so this is an area for a tax professional. Unmarried owners are not automatically limited to one shared $250,000 exclusion. Each qualifying owner may potentially claim an exclusion based on that person’s own share of the gain, ownership, use, and individual eligibility.

Let’s use the simple example:

Two unmarried partners purchase a home for $500,000 and own it equally.

Years later, they sell it for $1 million.

Ignoring selling costs, improvements, and other basis adjustments for the moment, that appears to create a $500,000 gain.

If each owner is entitled to half of the gain and each independently satisfies the IRS eligibility requirements, each may potentially exclude up to $250,000 of qualifying gain.

That can result in the entire $500,000 gain being excluded.

But the details matter.

The taxable gain is not always just the sale price minus the original purchase price. Improvements, selling expenses, depreciation, periods of nonqualified use, rental activity, and other adjustments may change the calculation.

Use a CPA or other qualified tax adviser before relying on the exclusion.

Should We Buy Together or Have One Person Buy?

There is no single right answer. Buying together may make sense when:

• Both incomes are needed for qualification
• Both people are contributing financially
• Both want a clear ownership interest
• The financing terms remain favorable
• The buyers have a written plan for separation or death

Having one person buy may make sense when:

• One person qualifies more easily alone
• The second person’s debt or credit weakens the application
• One person is supplying all funds
• The buyers intentionally want separate ownership
• Legal or financial advisers recommend that structure

But a one-borrower structure creates its own questions. Will the non-borrowing partner contribute to the mortgage without owning anything? Will they acquire an ownership interest later? Are their monthly payments rent, shared household expenses, or an investment? What happens if the relationship ends after they helped pay for improvements?

Again, write down the agreement. Do not rely on the belief that you will “figure it out later.”

Frequently Asked Questions

Do we have to be married to apply for a mortgage together?

Nope. Unmarried partners, friends, and family members may apply jointly, provided they satisfy the lender’s requirements.

Does marriage mean both spouses must be on the mortgage?

No. One spouse may apply individually, although state law, lender requirements, title, assets, debts, and occupancy can affect the transaction.

Can both people be on the deed if only one is on the loan?

Potentially, but buyers must confirm the lender’s requirements and understand the legal and tax consequences before changing or establishing title.

Can unmarried owners split the property 75/25?

A tenancy-in-common structure may permit unequal ownership percentages. An attorney and escrow officer should ensure the deed and co-ownership agreement accurately reflect the intended split.

What happens to an unmarried owner’s share after death?

It depends on the deed, estate plan, and applicable inheritance law. The interest may pass to the surviving owner, an heir, or another beneficiary.

Can two unmarried owners each use the home-sale exclusion?

Potentially. Each owner must independently satisfy the applicable IRS rules, and each exclusion applies to that person’s qualifying share of the gain.

Do unmarried co-owners need an attorney?

I strongly recommend legal advice before closing. A real estate agent and title company cannot replace a personalized co-ownership, estate-planning, and exit agreement.

My Final Thoughts

Buying a home with another person can be a wonderful way to combine resources, build equity, and create a shared life.

Marriage is not required, but solid planning is.

If you are unmarried, the biggest risk is not that you are prohibited from buying together. It is that you may have no automatic process for resolving disagreements, dividing equity, or handling a death.

If you are married, do not assume that marriage answers every ownership, inheritance, lending, and tax question either.

Before buying, talk openly about money. Decide how much each person is contributing. Understand who will be on the loan. Choose the ownership structure deliberately. Put an exit plan in writing. Coordinate the deed with your estate plan. And speak with a CPA about deductions and future capital gains.

These conversations may not feel romantic, but they are responsible. A well-planned purchase protects both people and gives the relationship room to change without turning a shared home into an impossible financial problem.
