Unmarried couples can buy a house together in Las Vegas, and the practice is far more common than most people expect. The National Association of Realtors reported that unmarried couples accounted for 9% of all U.S. home purchases in 2024. Nevada places no legal barrier on joint property ownership by unmarried partners, but the state provides fewer automatic protections than marriage, making careful legal and financial preparation essential before signing anything.
Key Takeaways
- Unmarried couples made up 9% of all U.S. home buyers in 2024, per the NAR Profile of Home Buyers and Sellers
- Nevada does not recognize common law marriage, so written ownership documents carry full legal weight
- Two ownership structures are available: joint tenancy (equal shares with right of survivorship) and tenancy in common (flexible splits)
- A cohabitation agreement is the single most important protective document for unmarried co-owners
- One partner can hold the mortgage while both appear on the deed – with proper legal guidance
Can Unmarried Couples Buy a House Together in Nevada?
Yes – and Nevada law makes it fully accessible. The NAR 2024 Profile of Home Buyers and Sellers confirmed that unmarried couples represent 9% of recent buyers nationally. Nevada state law (NRS Chapter 111) permits any two parties to hold title jointly regardless of marital status. See current conditions in the Las Vegas housing market guide before making any offer.
Nevada has not recognized common law marriage since 1943. That means an unmarried partner has no automatic legal claim to the other partner’s share of a property in the event of death or separation. Every right and obligation must be established through formal written documents, which is why legal preparation is not optional – it is foundational.
Choosing the Right Ownership Structure: Joint Tenancy vs Tenancy in Common
The ownership structure you select determines what happens to your shared investment under every major life scenario. With the Las Vegas median home price exceeding $420,000 in 2026, according to Las Vegas market data, a mistake in structuring ownership could expose either partner to significant financial loss. For more on this topic, see our fractional home ownership.
Joint tenancy requires both partners to acquire equal shares at the same time, with the same deed. Its defining benefit is the right of survivorship: if one partner dies, ownership transfers automatically to the survivor without probate. In Nevada, probate can take 6 to 18 months, so this protection has real practical value.
Tenancy in common offers flexibility. Partners hold ownership percentages that can reflect their actual financial contributions, and each partner’s share passes to their designated heirs rather than to the surviving co-owner automatically. This works well when one partner contributes a larger down payment or covers a greater share of monthly costs.
Citation: Nevada Revised Statutes Chapter 111 requires that joint tenancy be expressly created in the deed using language that specifically states the right of survivorship. Without that explicit language, Nevada courts presume tenancy in common by default. A real estate attorney should draft or review the deed before it is recorded to confirm the intended structure is properly established. (NRS 111.060)

Why a Cohabitation Agreement Is Non-Negotiable
A cohabitation agreement is a private legal contract defining how unmarried co-owners will manage shared property rights, expenses, and dispute resolution. The Consumer Financial Protection Bureau notes that co-borrowers each carry full legal responsibility for mortgage repayment regardless of any private arrangement, making an internal written agreement the only way to enforce fair cost-sharing.
Citation: The CFPB explains that both co-borrowers on a mortgage are equally liable for the full loan balance. Lenders do not enforce private side agreements between partners. A cohabitation agreement specifying each partner’s share of mortgage payments, maintenance costs, and exit conditions is the only document that governs internal financial obligations between unmarried co-owners outside of lender terms.

A well-drafted cohabitation agreement should address:
- Ownership percentages and how they correspond to each partner’s actual financial contributions
- Monthly cost-sharing covering the mortgage, property taxes, HOA fees, insurance, and utilities
- Maintenance and repair responsibilities and which partner holds authority over major decisions
- Exit provisions including buyout formulas, forced sale conditions, and timeline requirements
- Default scenarios specifying what happens if one partner stops making their agreed contribution
A real estate attorney familiar with Nevada law should draft the agreement. Fees typically range from $500 to $1,500 for a thorough document. That cost is a fraction of the expense of a contested property dispute.
Financing Strategies for Unmarried Co-Buyers
Unmarried couples face a mortgage decision that married couples do not: whether to apply jointly or have one partner apply solo. This decision turns on each partner’s credit score and debt-to-income ratio, both of which lenders evaluate separately for each applicant on a joint application.
Joint mortgage application uses both incomes to increase the total loan amount you may qualify for. This matters in the Las Vegas market where the median price exceeds $420,000. However, both partners’ debt loads and credit histories are factored into the rate. If one partner carries significant debt or has a low score, this can raise the interest rate or reduce approval odds.
Solo mortgage application may deliver a better rate if one partner has a significantly stronger credit profile. The non-borrowing partner can then be added to the deed, though the exact timing and method require care to avoid triggering the due-on-sale clause. Consult a real estate attorney before taking this approach.
For down payment planning, document in writing exactly who is contributing what amount. This becomes an exhibit in your cohabitation agreement and serves as evidence if ownership percentages are ever disputed.
Tax Implications for Unmarried Las Vegas Homeowners
Unmarried co-owners cannot file a joint federal tax return, which changes how mortgage interest and property tax deductions are allocated. Each partner may deduct only the portion of interest and taxes they actually paid, according to IRS Publication 936.
Citation: IRS Publication 936 governs the home mortgage interest deduction for co-owners who are not married to each other. Each co-owner may deduct the interest they personally paid, subject to applicable loan limits. Both partners must be listed as borrowers and use the property as their qualified home for the deduction to apply to each individual return. (55 words)
For a full breakdown of what buyers can deduct at purchase and in subsequent tax years, see the tax deductions guide for buyers and sellers.
One important note on the capital gains exclusion: unmarried co-owners who each meet the two-year ownership and use tests under IRS Section 121 may each exclude up to $250,000 of gain from the sale of their primary residence. This means the combined exclusion can reach $500,000 total – identical to what married couples receive – provided both partners individually satisfy the residency requirements.
What Happens to the Property If You Separate?
Without advance planning, separation can trigger expensive legal disputes over jointly owned property. Nevada courts can order a partition action, potentially forcing a sale even if one partner wants to keep the home, when co-owners cannot reach agreement.
A cohabitation agreement prevents partition litigation by specifying buyout price formulas, applicable timelines, and which dispute resolution method (mediation before court) applies. Without this document, Nevada partition actions can cost each party tens of thousands of dollars in attorney fees, appraisal costs, and court expenses.
The agreement should also address how already-paid closing costs are credited in any buyout calculation, as these upfront costs are often not recoverable if a property sells within the first few years.
Estate Planning Without Marriage Protections
Nevada intestacy law does not automatically grant an unmarried partner any inheritance rights. Without a valid will, a deceased partner’s share of the property passes to their legal heirs – typically parents, siblings, or children – not to the surviving co-owner.
For joint tenancy owners, the right of survivorship overrides intestacy, so this structure provides built-in inheritance protection. For tenancy in common owners, a will is not optional – it is the only instrument that directs the property share to the intended beneficiary.
Each partner should also consider these additional documents:
- Durable power of attorney so the surviving partner can manage shared property if one becomes incapacitated
- Beneficiary designations on any life insurance policies that cover mortgage payments
- Living trust to allow the property to transfer outside of probate if desired
If you later marry your co-owner, the title adjustment process is straightforward. See the house title name change after marriage guide for details on how to update the deed.

Frequently Asked Questions
Can an unmarried couple buy a house together in Las Vegas?
Yes. Nevada law allows any two people to jointly purchase and hold title to real property, regardless of marital status. Unmarried couples can choose joint tenancy or tenancy in common. A cohabitation agreement drafted by a Nevada real estate attorney is strongly recommended to define each partner’s rights and responsibilities.
What is the difference between joint tenancy and tenancy in common?
Joint tenancy gives both partners equal (50/50) ownership with a right of survivorship, meaning the property transfers automatically to the survivor at death – no probate required. Tenancy in common allows unequal ownership percentages and lets each partner designate their own heirs, but the property does not automatically transfer to the surviving co-owner.
Can one partner be on the mortgage while both are on the deed?
Yes. The borrower on the mortgage and the title holders on the deed do not need to be identical. One partner can sign the mortgage while both hold title as co-owners. The exact method requires coordination with your lender and a real estate attorney to avoid triggering the due-on-sale clause.
What happens to jointly owned property if we break up in Nevada?
If co-owners cannot agree, either partner can file a partition action in Nevada courts, which can force a sale. A cohabitation agreement specifying exit procedures, buyout formulas, and dispute resolution methods is the strongest protection against this outcome. Without one, legal costs can reach tens of thousands of dollars.
Do unmarried co-owners receive the same tax benefits as married couples?
Unmarried co-owners file separately, so each deducts only the mortgage interest and property taxes they personally paid. For capital gains on a home sale, each partner who individually meets the two-year ownership and use test may exclude up to $250,000 of gain under IRS Section 121, for a combined potential exclusion of $500,000.
