Yes, you can buy property with your parents, and for many Australians in 2026 it is one of the most practical ways to break into a housing market where median prices in Melbourne sit well above what a single income can comfortably service. Whether your parents step in as co-borrowers, co-owners, or as guarantors on your loan, each structure carries distinct legal, financial, and relationship consequences that are worth understanding before you sign anything.

What Are the Main Ways Parents Can Help You Buy Property?

There are three broad structures lenders and conveyancers commonly see when families pool resources to purchase real estate. Understanding the difference matters enormously, because each one affects whose name is on the title, who is liable for the debt, and what happens if someone wants to exit the arrangement.

Co-Borrowing (Joint Applicants)

In a co-borrowing arrangement, both you and your parents are named on the mortgage. All parties are jointly and severally liable, meaning the lender can pursue any one of you for the full debt if repayments fall behind. The upside is that your parents’ income can significantly boost borrowing capacity. According to CoreLogic data from early 2026, Melbourne dwelling values have risen approximately 6.2% year-on-year, so the extra borrowing power a co-borrower provides can be the difference between securing a property now versus waiting another two to three years.

Co-Ownership (Joint Title)

Co-ownership means your parents are listed on the Certificate of Title alongside you. You can hold the property as joint tenants (equal shares with right of survivorship) or as tenants in common (defined percentage splits). Tenants in common is generally preferred in family arrangements because each party’s share can be passed through their own will rather than automatically transferring to the surviving owner.

Guarantor Arrangement

A guarantor structure keeps the mortgage in your name only, but your parents offer their own property as additional security. This is popular because it can eliminate the need for Lenders Mortgage Insurance (LMI) without requiring your parents to be named borrowers. Most major lenders in Australia allow guarantors to limit their exposure to a defined portion of the loan, sometimes called a “limited guarantee,” which reduces the risk to your parents compared with an unlimited guarantee over the full debt.

How Does a Family Guarantee Actually Work in Practice?

When a lender accepts a family guarantee, they take a second mortgage over your parents’ property as additional collateral. If your deposit is only 5%, your parents’ guarantee can cover the remaining gap, pushing your effective security above the lender’s 80% loan-to-value ratio threshold. This is how many first-home buyers avoid paying LMI, which on a $750,000 loan can amount to more than $15,000 depending on the lender and the loan-to-value ratio.

The key risk is straightforward: if you default, the lender can pursue your parents’ home. Before entering any guarantor arrangement, your parents should obtain independent legal and financial advice. Many lenders now require proof of that independent advice as a condition of approving the guarantee. It is also worth reviewing whether your parents have sufficient equity. SQM Research’s 2025 figures indicate that many inner-Melbourne homeowners who purchased more than a decade ago now hold equity positions well above 60% of current valuations, making them well-placed to act as guarantors from an equity standpoint, though their own retirement income needs must still be weighed carefully.

What Legal and Tax Risks Should Co-Buyers With Parents Know About?

This is where many families underestimate the complexity. There are at least four distinct risk areas to address before settlement.

Stamp Duty Implications

In Victoria, stamp duty (land transfer duty) is calculated on the full purchase price, and all co-owners are liable. Critically, first-home buyer duty concessions apply only to the eligible buyer’s share. If your parents own other property, their share of a co-purchase may be subject to full duty rates, and they will not qualify for any first-home buyer exemption. On a $700,000 property, the difference between a full exemption and paying standard duty on a 50% share can exceed $14,000. Always get a stamp duty estimate from a conveyancer before committing.

Capital Gains Tax (CGT)

Your principal place of residence is generally CGT-exempt, but your parents’ share of the property may not be if they already own their own home. The ATO treats each co-owner’s interest separately. In a tenants-in-common arrangement, your parents’ share could generate a CGT event on eventual sale. According to guidance published by the Australian Taxation Office, partial CGT exemptions can apply in some circumstances, but the calculations are complex and require a tax professional to model correctly.

Relationship and Estate Planning Risk

Property disputes within families are among the most emotionally costly legal proceedings. A co-ownership agreement drawn up by a solicitor before purchase should address: what happens if one party wants to sell, how ongoing costs (rates, maintenance, mortgage repayments) are split, and how the property is handled if one owner passes away or faces bankruptcy. These are uncomfortable conversations, but skipping them is far riskier.

Impact on Your Parents’ Borrowing Capacity

If your parents co-sign your mortgage, that liability appears on their credit file and reduces what they can borrow in their own right. This matters if they are planning to refinance, downsize, or access equity for retirement. A mortgage broker can run the numbers across both scenarios before you proceed.

Are There Government Schemes That Can Help Instead of (or Alongside) a Family Arrangement?

Before structuring a co-purchase with parents, it is worth checking whether a government scheme changes the equation. The Family Home Guarantee (FHG), administered by Housing Australia on behalf of the Australian Government, supports eligible single parents or single legal guardians with at least one dependent to purchase a home with a deposit as low as 2%, without paying LMI. The guarantee covers up to 18% of the property value. Applicants must be Australian citizens or permanent residents aged 18 or over, intending to owner-occupy, and must not currently own other property. If you qualify as a single parent, the FHG may reduce or eliminate the need for your own parents’ involvement as guarantors altogether.

Separately, the First Home Guarantee (previously the First Home Loan Deposit Scheme) allows eligible first-home buyers to purchase with just a 5% deposit without LMI, supported by a government-backed guarantee. Property price caps apply by state and territory. In Victoria for 2025-26, the cap for capital city and regional centre purchases sits at $800,000.

These schemes do not prevent a co-purchase with parents in principle, but lenders administering the schemes have specific eligibility criteria around who can be named on the loan, so confirm the details with a participating lender or mortgage broker before assuming the two can be combined.

How Do You Protect Everyone’s Interests in a Co-Purchase?

The single most important document in any co-buying arrangement is a co-ownership agreement (sometimes called a property ownership agreement or joint venture agreement). This is a legally binding contract, separate from the mortgage documents, that sets out:

• Each party’s ownership percentage and financial contribution
• How ongoing costs (mortgage repayments, rates, insurance, maintenance) are shared
• Decision-making processes for major decisions such as selling or renovating
• A mechanism for one party to buy out the other, including how the buyout price is determined
• What happens in the event of death, divorce, or financial hardship affecting any co-owner
• A timeline or milestone (for example, when you reach a certain equity level) at which the parents’ names are removed from the title or the guarantor arrangement is released

Both parties should have independent legal representation when drafting and reviewing this agreement. A family lawyer or conveyancer can prepare the document and flag any clauses that create unintended obligations. The cost of getting this right upfront is trivially small compared to the cost of a family property dispute later.

Given where Melbourne property values are heading, deciding when to buy is just as important as deciding how.

What Are the Pros and Cons of Buying Property With Your Parents?

Advantages

• Larger deposit or borrowing capacity, getting you into the market sooner
• Avoid or reduce LMI through a guarantor structure
• Potentially access better interest rates by presenting a lower LVR to lenders
• Shared ownership can reduce individual financial pressure on mortgage repayments during early ownership years
• Can be an effective intergenerational wealth transfer strategy if structured correctly

Risks and Downsides

• Parents’ property is at risk if repayments default in a guarantor structure
• Stamp duty concessions may be partially or fully lost depending on parents’ ownership status
• CGT can apply to your parents’ share on sale if they already own their principal residence
• Co-ownership complicates future refinancing, selling, or estate planning
• Relationship strain if financial expectations are not documented clearly from the outset
• Parents’ borrowing capacity is reduced while the guarantee or co-loan is in place

Buying property with your parents can be a genuinely effective strategy for getting into the market, but it works best when all parties enter the arrangement with clear legal documentation, independent advice, and a shared understanding of both the financial commitments and the exit plan. The structure you choose, co-borrower, co-owner, or guarantor, should reflect your family’s specific circumstances rather than simply whichever option requires the least paperwork. Take the time to model the numbers, get the legal documents right, and revisit the arrangement regularly as your equity grows and your financial position changes.
