Buying a home with someone you love represents a significant financial investment. However, the excitement of house hunting can often overshadow the complex legal and financial realities of co-ownership.
When you choose to purchase a property with a partner, or simply a boyfriend and girlfriend, you are creating shared debt, shared ownership, and shared risk.
We believe that clarity today prevents conflict tomorrow. Especially for those buying a house before marriage, understanding the difference between personal promises and legal obligations is vital.

Decide If Buying Together Makes Sense
The first branch of the decision tree concerns financial fit. Many readers ask, “Can two people buy a house together?” The answer is yes, but the more important question is, “Should you?” Before you start looking at listings, we suggest sitting down for a transparent financial audit.
Start by comparing your incomes, savings, debts, and credit scores. Often, buying a house with a partner can help with income qualification, allowing you to afford a larger home than you could on your own.
However, if one partner has significant debt or a low credit score, they may actually hinder the application. In some cases, it makes more sense for the partner with the stronger financial profile to buy on their own, while the other contributes to the household in a different way.
If you are a first-time home buyer in California, it is crucial to have a clear purchase plan. If one partner has a high level of student loan debt or car payments, you might need to focus on lowering your debt-to-income ratio before applying.
Ask yourselves: “Are we stronger together on the mortgage, or does buying together create more risk?” If both parties are financially ready, you can move to the next gate in the decision tree.
Pro Tip:
- Don’t let a “good deal” or a rising market rush your financial transparency. If you aren’t comfortable sharing your full credit report and debt history with your partner today, you aren’t ready to sign a 30-year financial contract with them tomorrow.
Decide Who Goes on the Mortgage
It is a common misconception that the mortgage and the title are the same thing. They are not. The mortgage is a contract with a lender that specifies who is responsible for repaying the loan. The title is a legal document that declares who owns the property.
When you are buying a house with an unmarried partner, you must decide who will be the official borrower. If both names are on the mortgage, you are both “jointly and severally” liable.
This means that if your partner stops paying their share, the lender will still expect you to make the full payment. The CFPB notes that even a single missed payment by a co-borrower can negatively affect both borrowers’ credit scores.
Being a co-borrower on a mortgage requires total trust. Lenders will look at both credit profiles during the approval process, and typically, the lower of the two middle credit scores will dictate the interest rate. If one partner has credit issues, it could indicate that your mortgage will be denied.
Even after receiving conditional approval, things can change. If you are asking, “Can you get a mortgage with someone you’re not married to?” or “Do you have to be married to buy a house together?” the answer is that lenders treat unmarried co-borrowers similarly to married ones, but without the built-in legal protections of family court to settle disputes later.
According to the Consumer Financial Protection Bureau (CFPB), co-borrowers are jointly responsible for the entire mortgage debt. This means the lender can pursue either person for the full amount. To protect your interests, we recommend reviewing your mortgage responsibilities, title options, and payment obligations in writing well before your closing date.
Pro Tip:
- If you decide to put only one partner on the mortgage for credit reasons, remember that the lender cannot use the “non-borrowing” partner’s income to qualify. This may lower your total purchasing power, so have your mortgage broker run the numbers for both scenarios before you start house hunting.
Decide Who Goes on the Title
While the mortgage concerns the debt, the title concerns the rights. Deciding how to hold title is one of the most important aspects of how to protect yourself when buying a house with a partner. Title dictates who can sell the property, who inherits it if one person dies, and how much of the “bundle of rights” each person holds.
When buying a house with someone you’re not married to, California law provides several options. According to the California Civil Code, ownership can be held in several forms:
- Joint Tenancy: Usually includes the “right of survivorship,” meaning if one partner passes away, the other automatically inherits their share.
- Tenancy in Common: Allows for unequal ownership percentages. If one partner dies, their share goes to their heirs, not necessarily the surviving partner.
- Community Property: Generally reserved for married couples or registered domestic partners.
It is possible for one partner to be on the mortgage while both are on the title. However, this creates a risk for the person on the mortgage, as they are 100% responsible for the debt but only own 50% (or less) of the asset.
Because title choice has long-term legal and tax implications, we strongly advise speaking with a real estate attorney or title professional to ensure you choose the structure that matches your intent.
Pro Tip:
- In California, “Joint Tenancy” is popular because it avoids probate, but it requires equal ownership shares. If you and your partner intend to own the home at a 70/30 or 60/40 split, you must hold title as “Tenancy in Common.” Always verify that your title choice matches the ownership percentages in your private contract.
Decide How Ownership Shares Work
Many couples default to a 50/50 split, but this isn’t always the most equitable choice. What if one partner is providing 90% of the down payment? Or what if one partner earns significantly more and will be covering 70% of the monthly mortgage?
In these cases, a contract for unequal ownership of a house may be appropriate. This allows you to define ownership based on contribution. For example:
The Down Payment Gap
If one person pays the full down payment, the agreement might state that they receive that initial investment back first if the home is sold, with remaining profits split 50/50.
Sweat Equity vs. Cash
One partner might handle the mortgage payments while the other pays for a major kitchen remodel.
Gift Funds
If parents provide a gift for the down payment, you should document whether that gift was intended for one person or both.
Sometimes, one partner might act as a support system rather than a co-owner. This is different from cosigning a mortgage, where a person takes on debt responsibility to help another qualify but may not intend to live in or own the home.
For an unmarried couple buying a house, the goal is to ensure that if the relationship ends, the financial distribution reflects the actual contributions made.
Decide How Costs Will Be Split
The mortgage payment is often just the tip of the iceberg. To truly protect yourself, you need a granular plan for the day-to-day costs of homeownership. We recommend creating a budget that covers:
- Upfront Costs: Who is paying the earnest money, the appraisal fee, and the inspection?
- Closing Costs: Will you split these equally? You may want to look into who pays closing costs in your specific California county to negotiate better.
- Recurring Costs: Property taxes, HOA dues, and homeowners insurance can add hundreds to your monthly bill.
- Maintenance: Who pays when the water heater breaks? Having an emergency reserve fund is essential.
Before you gather the documents needed to buy a house, agree on a “household account” structure. Some couples find success by contributing a percentage of their income to a joint account for house expenses.
Others prefer a strict 50/50 split. If you are tight on cash, you might even explore no-closing-cost loan options in California to preserve your savings for future repairs.
Keeping detailed records of major payments and saving receipts can prevent “who paid for what” arguments three years down the line.
Pro Tip:
- Open a dedicated “House Account” as soon as you start looking at homes. Both partners should deposit their share of the earnest money and inspection fees here. This creates a clean “paper trail” for the lender’s underwriters, making it much easier to document the source of your funds during the approval process.
Decide What Goes in Writing
Verbal promises are rarely enforceable in real estate disputes. If you want to know how to protect yourself when buying a house with a partner, the answer is almost always: put it in writing. An unmarried couple buying a house contract (often called a Co-ownership Agreement or Cohabitation Agreement) acts as your roadmap.
This document should clearly outline:
- Percentage of ownership for each person.
- Who is responsible for which monthly payments?
- A protocol for what happens if one person stops paying.
- The right of first refusal (allowing one partner to buy out the other before the home is listed publicly).
- How a future sale price will be determined.
The CFPB emphasizes that because unmarried partners don’t have the same legal framework as spouses, having a separate agreement prepared by an attorney is a vital safety net.
A contract for unequal ownership of a house or a simple agreement on repair duties, having it signed and notarized, provides peace of mind that allows you to enjoy your new home without the “what if” hanging over your head.
Decide the Exit Plan
Talking about a breakup while buying a home feels pessimistic, but it is actually the ultimate form of protection for both people. An exit plan ensures that if things don’t work out or if one person simply wants to move on, neither person is trapped in a financial nightmare.
The Buyout
If one partner wants to stay, how will you determine the home’s value? We suggest agreeing to use a neutral, third-party appraisal. To facilitate this, one partner might use a cash-out refinance to pay the departing partner their share of the equity.
The Refinance Requirement
Remember that removing someone’s name from the title does not remove them from the mortgage. The partner staying in the house must usually qualify for a new loan on their own to release the other from the debt.
You should discuss what happens if you cannot refinance after separation, as the person moving out may be unable to buy a new home while still tied to the old mortgage.
Market Fluctuations
What if the home has lost value? You need a plan for how to handle a “short” sale or how to split the loss.
By planning for these moments now, you can focus on making the home a success. If the person staying needs lower mortgage payments in California to manage the house alone, you can explore loan restructuring options together while emotions are still calm.
Pro Tip:
- When drafting a buyout agreement, decide ahead of time how to handle “selling costs.” In a real-world sale, you’d likely pay 5%–6% in agent commissions. Many savvy couples agree to deduct these theoretical costs from the total equity before calculating the final buyout check to ensure the partner staying in the house isn’t unfairly burdened.
Decide Which Loan Path Fits
Once you have your internal agreements settled, it’s time to choose the right financial product. The loan you choose should align with your long-term exit and ownership plans.
- Conventional loan options in California: These are often best for partners with high credit scores and at least a 3% to 5% down payment. They offer stability and are generally easier to manage if you plan to keep the home for a long time.
- FHA loan in California: If one partner has a lower credit score or you have limited savings, an FHA loan can be a great entry point. However, remember that FHA loans have specific rules about co-borrowers and primary residency.
This is where how a mortgage broker can help becomes clear. We can run scenarios for both of you together versus one of you alone.
We help you understand how to buy a house with someone you’re not married to by finding lenders that are “unmarried-borrower friendly” and offer the best terms for your unique combined financial profile.
Review the Before You Sign Checklist
Before you walk into the escrow office, take one final look at this checklist. This summary ensures you haven’t missed any vital protection steps:
- Financial Transparency: Have you both seen each other’s full credit reports and bank statements?
- Mortgage Responsibility: Do you both understand that you are 100% liable for the full payment, regardless of your internal split?
- Title Strategy: Have you consulted an expert on whether Joint Tenancy or Tenancy in Common is better for your situation?
- Written Agreement: Is your co-ownership contract signed and stored in a safe place?
- Expense Plan: Do you have a shared account or a clear spreadsheet for monthly bills and repairs?
- The “What If” Plan: Do you know exactly how a buyout or a sale would work if one person leaves?
- Loan Choice: Have you compared Conventional and FHA options to see which provides the best protection and lowest cost?

FAQs
Do you have to be married to buy a house together?
No, you do not have to be married. Lenders allow any two (or more) people to apply as co-borrowers. However, unmarried couples should be extra diligent about putting ownership and exit terms in writing since they do not have the default protections of marriage laws.
Can you buy a house together without being married?
Yes, it is very common. The key is to decide how you will hold the title (such as Tenancy in Common) and to create a co-ownership agreement that specifies who pays for what and how equity is split.
Can you get a mortgage with someone you’re not married to?
Absolutely. Lenders will review the income, assets, and credit of both borrowers. Keep in mind that the lender will usually use the lower of the two partners’ middle credit scores to determine the interest rate.
What should be in an unmarried couple’s house-buying contract?
At a minimum, it should include the payment split, ownership percentages, a plan for repairs, a process for one partner to buy out the other, and rules for what happens if a partner misses a payment or the couple breaks up.
How do you buy out a partner in a house?
The most common way is to agree on a fair market value (via appraisal), calculate the equity share owed to the departing partner, and then perform a refinance. This allows the staying partner to pay out the equity and remove the other person from the mortgage responsibility.
