Buying a house with other people works only if three things line up: the way your names go on the deed, a written co-ownership agreement signed before closing, and a mortgage that every borrower can qualify for and stay current on. Knowing how to buy property as a group means treating each of those pieces as a separate decision with its own legal weight, because a handshake understanding about “who pays what” carries no force in court. The steps below apply whether you’re buying with a sibling, a partner, or three friends pooling savings to break into a competitive market.
Decide How You’ll Hold Title
How the deed is titled controls who owns what percentage, what happens if someone dies, and how easily an owner can leave. Get this wrong and you can lose control of the property to a stranger or trigger an expensive probate case. Three structures cover the vast majority of group purchases.
Tenancy in Common
Tenancy in common is the most flexible option because each owner can hold a different percentage. If one person contributes 60% of the purchase price and another contributes 40%, the deed can reflect that split. Each owner can sell, mortgage, or leave their share to an heir without permission from the others. That flexibility cuts both ways. If one owner sells to someone the group has never met, the remaining owners are stuck with a co-owner they didn’t choose. Most states default to tenancy in common when the deed doesn’t specify another arrangement, so groups that want something different need to say so explicitly.
Joint Tenancy With Right of Survivorship
Joint tenancy requires equal ownership shares and includes automatic transfer at death. When one joint tenant dies, that interest passes directly to the surviving owners without probate. Four conditions must all be satisfied at once: every owner acquires their interest at the same time, through the same deed, in equal shares, and with equal rights to possess the whole property.1Legal Information Institute. Joint Tenancy If any of those conditions breaks down later, the joint tenancy can convert into a tenancy in common automatically. The structure suits family members or close partners who want the property to stay within the group no matter what.
Title Held Through an LLC
Some groups form a multi-member limited liability company and put the property in the LLC’s name. The main advantage is liability protection: if someone gets injured on the property and sues, the lawsuit targets the LLC’s assets rather than each owner’s personal bank accounts. The LLC operates under an operating agreement that sets voting rights, management duties, profit splits, and what happens when a member wants out. Transferring ownership becomes simpler because you assign LLC membership interests instead of recording a new deed.
The trade-off is upkeep. Most states require an annual or biennial filing to keep the LLC in good standing, with fees ranging from under $50 to several hundred dollars. Domestic LLCs are currently exempt from federal beneficial ownership reporting to FinCEN after a 2025 interim rule removed that obligation for U.S.-formed entities.2Financial Crimes Enforcement Network. Beneficial Ownership Information Reporting The operating agreement itself should be drafted by an attorney familiar with real estate LLCs, and that legal cost adds to the upfront investment.
Sign a Co-Ownership Agreement Before Closing
A written co-ownership agreement is the single most important document in a group purchase. It governs everything the deed and the mortgage don’t cover. Without it, disputes default to your state’s property law, which rarely matches what the group actually intended. Have a real estate attorney draft or review this document before closing.
Contributions and Equity Splits
Record exactly how much each person contributes toward the down payment and closing costs, and state whether unequal contributions produce unequal equity stakes. If one person puts in $50,000 and another puts in $20,000, the agreement needs to say whether they own the property 71/29 or 50/50. Set a formula for splitting recurring costs too: the mortgage payment, property taxes, homeowner association dues, and insurance premiums. Groups that skip this step end up arguing within the first year about who owes what.
Maintenance and Improvements
Routine repairs and major improvements need separate rules. Specify how routine upkeep is divided, how the group funds large projects like a roof replacement, and at what dollar threshold a repair requires group approval. A common approach lets any owner authorize minor repairs up to $500 but requires unanimous consent above that. Some groups fund a shared reserve account with monthly contributions so nobody has to scramble when a major system fails.
Usage Rules
If the group plans to live in the property together, the agreement should cover guest policies, noise expectations, and whether any owner can rent out their space short-term. For investment properties, it should address tenant selection, lease terms, and how rental income gets distributed. These details feel unnecessary when everyone gets along, and they become critical when an overnight guest turns into a permanent resident or one owner wants to list a bedroom on a rental platform.
Exit and Buyout
Every co-ownership agreement needs a clear process for what happens when someone wants out. The standard approach gives the remaining owners a right of first refusal to buy the departing owner’s share before it can be offered to outsiders. Specify how the property gets appraised for buyout purposes, how long the remaining owners have to arrange financing, and what happens if nobody can afford the buyout. A typical timeline runs 60 to 90 days from notice to closing.
The agreement should also address what happens if an owner dies, becomes incapacitated, or files for bankruptcy. Requiring that a deceased owner’s estate offer the share back to the group first prevents an unknown heir from becoming your new co-owner. Without those provisions you could find yourself sharing the property with someone’s estranged relative or a bankruptcy trustee looking to liquidate quickly. When co-owners hit an impasse and no agreement is in place, any one of them can file a partition action asking a court to divide or sell the property, a process that is expensive, slow, and largely avoidable with good drafting up front.
Qualify for the Mortgage Together
Qualifying for a group mortgage is harder than qualifying solo. Lenders evaluate every borrower on the loan, and the group is only as strong as its weakest member.
Credit Scores
For conventional loans sold to Fannie Mae, the automated underwriting system no longer applies a fixed minimum credit score. As of November 2025, Fannie Mae eliminated the 620 minimum and relies on a comprehensive analysis of all risk factors in the application.3Fannie Mae. Selling Guide Announcement SEL-2025-09 That doesn’t mean credit scores stopped mattering. The system still uses the lowest median score among all borrowers to assess risk, and a low score will push the interest rate higher or produce a denial. Many individual lenders also maintain their own minimum score requirements above what Fannie Mae mandates, so a co-borrower with poor credit can still sink the application.
FHA loans work differently. The minimum credit score is 500, but borrowers scoring between 500 and 579 must put at least 10% down, while those at 580 or above qualify for the standard 3.5% down payment. FHA also uses the lowest median score among co-borrowers to set terms. One important limit for unrelated groups: when a non-occupant co-borrower who isn’t a family member is on the loan, the maximum loan-to-value ratio drops to 75%, meaning the group needs a 25% down payment.4U.S. Department of Housing and Urban Development. FHA Single Family Housing Policy Handbook
Debt-to-Income Ratio
Lenders calculate the group’s debt-to-income ratio by combining everyone’s gross monthly income and recurring debts. For Fannie Mae loans run through automated underwriting, the maximum DTI is 50%. Manually underwritten loans have a tighter cap of 36%, which can stretch to 45% with strong credit scores and cash reserves.5Fannie Mae. Debt-to-Income Ratios Because these ratios combine everyone’s finances, one co-borrower with heavy student loan or car payments can push the group over the limit even if everyone else is in good shape. Run the numbers before you apply.
Documentation and Gift Funds
Every borrower on the application must provide tax returns, recent pay stubs, and bank statements to verify income and assets. Self-employed co-borrowers face additional scrutiny and may need to supply profit-and-loss statements. If any part of the down payment comes from someone who won’t be on the loan, the lender requires a gift letter signed by the donor confirming the money is not a loan to be repaid. The letter must include the dollar amount, the donor’s relationship to the borrower, and a statement that no repayment is expected.6Fannie Mae. Personal Gifts Lenders verify these funds carefully because a disguised loan would raise the group’s true debt burden beyond what the application reflects.
Joint and Several Liability
This is where most group purchases get uncomfortable. Every person on the mortgage note is jointly and severally liable for the full loan amount, not just their proportional share. If one co-borrower stops paying, the lender doesn’t care about your internal agreement about who owes what. The bank can pursue any single borrower for the entire monthly payment, and a missed payment damages everyone’s credit score equally. That reality is the strongest argument for choosing co-borrowers carefully and building default provisions into the co-ownership agreement.
Handle the Tax Consequences From Year One
Group ownership creates tax situations that don’t come up in a solo purchase. Getting them wrong can mean a higher tax bill, IRS scrutiny, or lost deductions.
Splitting the Mortgage Interest Deduction
Co-owners who itemize can each deduct the share of mortgage interest they actually paid during the year. Total deductible mortgage debt is capped at $750,000 for loans originated after December 15, 2017, or $375,000 if married filing separately. The lender sends one Form 1098 to the primary borrower, so the other co-owners need to attach a statement to their tax return showing how much interest they each paid, along with the name and address of the person who received the 1098.7Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction Failing to coordinate this means someone claims too much and someone else loses a legitimate deduction.
Gift Tax on Unequal Contributions
When one person contributes significantly more to the purchase but takes an equal ownership share, the IRS may treat the excess as a gift. The annual gift tax exclusion for 2026 is $19,000 per recipient.8Internal Revenue Service. What’s New – Estate and Gift Tax If one co-owner contributes $80,000 more than their ownership share reflects, the excess above $19,000 could require a gift tax return. The simplest way to avoid the issue is to match ownership percentages to actual contributions, which is one reason tenancy in common works well when contributions are uneven.
Insure the Property for a Group
Standard homeowners policies are designed for individual or married-couple ownership, so insuring a group-owned property takes extra coordination. Every person whose name is on the deed should be listed as a named insured on the policy, not just the person who arranged the coverage. A named insured can file claims, adjust coverage limits, and participate in policy decisions. If a co-owner appears on the deed but not the policy, they may lack coverage for losses affecting their interest.
Liability coverage deserves particular attention. A standard policy provides at least $100,000 in liability protection, but insurance professionals generally recommend $300,000 to $500,000 for properties with multiple owners. Co-owners with significant personal assets should consider an umbrella policy above the base homeowners coverage. Every group member has a financial stake in adequate limits, because a liability claim that exceeds the policy can come after each owner personally.
Close and Record Title
Closing on a group purchase works much like a standard closing, except every co-borrower must be present or represented by a power of attorney to sign. The two key documents are the deed, which transfers ownership, and the mortgage note, which is each borrower’s personal promise to repay the loan.
Federal law requires the lender to deliver the Closing Disclosure to every borrower at least three business days before the closing date.9Consumer Financial Protection Bureau. TILA-RESPA Integrated Disclosure FAQs The document itemizes every cost of the transaction: loan fees, title insurance premiums, property tax prorations, and prepaid items. Every group member should review it carefully and compare it against the Loan Estimate received earlier. If numbers shift significantly, the three-day window gives you time to ask questions before you’re locked in.
A notary public verifies each signer’s identity and witnesses the signatures. Notary fees are set by state law and typically run between $5 and $25 per signature, though states without a fee cap may charge more. After signing, the deed goes to the county recorder’s office for entry into public records. Recording provides constructive notice to the world that the group holds legal title, which protects against competing ownership claims.
Once recording is complete, the title insurance policy finalizes. It protects the owners against defects in title that existed before the purchase but weren’t discovered during the title search, such as undisclosed liens, forged documents in the chain of title, or boundary disputes. For a group purchase, the policy should name every co-owner. With the deed recorded and title insurance in place, the group takes legal and physical possession.
Plan for a Co-Owner’s Financial Trouble
One risk that catches group buyers off guard is what happens when a co-owner’s personal financial problems follow them onto the deed. A judgment, tax lien, or bankruptcy filing by one owner can affect the entire property.
Judgment Liens
If a creditor wins a lawsuit against one co-owner, the resulting judgment lien can attach to that owner’s interest in the property. In most states the lien attaches only to the debtor’s share, not the entire property, but it still clouds the title, making it difficult for the group to sell or refinance until the debt is resolved. Homestead exemptions may limit a creditor’s ability to force a sale, though the strength of that protection varies by state and may not extend to co-owners who don’t live on the property. Holding title through an LLC can provide a buffer, since a creditor’s claim runs against the member’s LLC interest rather than the real estate directly.
Bankruptcy
When a co-owner files for bankruptcy, an automatic stay immediately freezes most actions involving that person’s property, including their share of co-owned real estate.10Office of the Law Revision Counsel. 11 U.S. Code 362 – Automatic Stay The remaining owners cannot sell or refinance the property without getting permission from the bankruptcy court to lift the stay. A trustee could also seek to sell the debtor’s interest to pay creditors, meaning the group could end up with a co-owner they never chose. The co-ownership agreement should address this explicitly, ideally by requiring the bankrupt owner’s interest to be offered to the group first at an appraised value. Appraisals for buyout purposes typically run between $300 and $600 for a single-family home, depending on location and property type.
