Co-buying a home is more common than it used to be. Rising prices, high interest rates, and the difficulty of qualifying alone have pushed more buyers to consider purchasing with a friend, a sibling, a romantic partner, or a business partner.

Co-buying a home is more common than it used to be. Rising prices, high interest rates, and the difficulty of qualifying alone have pushed more buyers to consider purchasing with a friend, a sibling, a romantic partner, or a business partner. In North Carolina, this is entirely legal and increasingly practical. But going into it without understanding the legal, financial, and relational dynamics is how people end up in situations they deeply regret. Here is what you need to know before you sign anything with someone else.
When two or more people buy a property together in NC, the first decision is how ownership will be structured legally. There are two primary options.
Joint tenancy with right of survivorship. Under this structure, all owners hold equal shares and if one owner dies, their share automatically passes to the surviving owner or owners without going through probate. This is common for married couples and long-term partners. It requires equal ownership percentages.
Tenancy in common. Under this structure, owners can hold unequal shares, and each owner's interest passes through their estate when they die rather than automatically to the co-owner. This is the more flexible structure for friends or co-buyers who are contributing different amounts to the down payment or who want their share to pass to their own heirs rather than the co-owner.
The choice between these two structures has real legal and estate implications. Talk to a real estate attorney before you decide. This is not a detail to sort out on the fly at closing.
This is the conversation most co-buyers do not have before they close, and it is the one that causes the most damage when things go sideways.
Life changes. People get new jobs in other cities. Relationships end. Financial circumstances shift. Priorities evolve. What happens when one co-owner wants to sell and the other does not? What happens when one person stops being able to pay their share of the mortgage?
A co-ownership agreement, also called a tenancy in common agreement or a co-buying agreement, addresses these scenarios in advance. It is a private legal document between the co-owners that covers things like: what happens if one party wants to sell, what the right of first refusal process looks like if one party wants to buy the other out, how expenses are split, how decisions about the property are made, and what happens if one party defaults on their share of the mortgage.
This document is not required by North Carolina law to close on a home. It is required by common sense. Get it drafted by an attorney before you close.
When you co-buy a home with another person and you both go on the mortgage, both of your credit profiles, income, and debt are considered in underwriting. This cuts both ways.
The benefit is that combining incomes can increase your qualifying purchase price and give you access to better rates if both profiles are strong.
The risk is that both parties are fully liable for the entire mortgage, not just their share. If your co-buyer stops paying, the lender does not split the debt. They come after both of you for the full amount. A missed payment on a co-owned property damages both people's credit scores equally.
This is why the co-ownership agreement matters so much. The mortgage is a joint obligation regardless of what your private agreement says. Your private agreement governs what happens between the two of you when one party fails to meet their obligations. It does not change what you owe the bank.
If one person contributes more to the down payment than the other, that needs to be documented and reflected in the ownership structure. A tenancy in common allows unequal ownership percentages, so a co-buyer who puts in 70% of the down payment can hold a 70% ownership interest. But this needs to be established clearly in the deed and in your co-ownership agreement before closing.
Gift funds from parents helping one party with the down payment add another layer of complexity that your lender will need to document. Be upfront with your loan officer about where the funds are coming from so there are no surprises in underwriting.
Unmarried co-buyers have fewer legal protections than married couples in most states, including North Carolina. There is no automatic community property protection, no automatic inheritance right, and no built-in framework for resolving disputes over a shared asset.
This makes the co-ownership agreement even more critical for unmarried co-buyers. You are essentially creating by contract the protections that marriage provides by law. The time to do this is before you close, not after a dispute arises.
Before you buy together, agree on the exit strategy. How long do you plan to own the property together? What is the trigger for selling: a certain number of years, a life event, a financial threshold? What if the market is down when one person wants to sell? These conversations are uncomfortable before a purchase and nearly impossible after a dispute begins. Have them now.
