Shared Ownership: The Forgotten Pathway to Home Ownership

For many aspiring first-home buyers, home ownership can feel further away than ever.

Property prices remain high, lenders are applying stricter affordability assessments, and the cost of living continues to place pressure on household budgets. While saving a deposit is still important, many buyers discover that servicing a mortgage on a single income is often the greater challenge.

As a result, more New Zealanders are looking beyond the traditional model of purchasing a property on their own and are exploring shared ownership arrangements.

For the right people, shared ownership can be an effective way to get onto the property ladder sooner.

What is Shared Ownership?

Shared ownership involves two or more people purchasing a property together.

The parties may be siblings, friends, parents and adult children, extended family members, or even unrelated investors and occupiers who have aligned goals.

By combining deposits, incomes and borrowing capacity, purchasers may be able to acquire a property that would otherwise be out of reach.

In most cases, each owner holds a separate share in the property as tenants in common. The ownership interests do not have to be equal and can reflect each person's financial contribution to the purchase.

For example, one owner may contribute a larger deposit and hold a greater share, while another contributes more towards the mortgage repayments over time.

Why is Shared Ownership Becoming More Popular?

Historically, many people expected to buy their first home independently or with a spouse or partner.

Today's housing market has prompted people to be more creative.

We are increasingly seeing first-home buyers join forces with siblings, close friends and parents to overcome the challenges posed by high property prices and lending restrictions.

Shared ownership allows buyers to pool resources, reduce the amount each individual needs to contribute and potentially enter the market sooner than they otherwise could.

For many people, the question is no longer whether they can purchase a property on their own, but whether they can achieve home ownership by working together.

The Importance of Having a Clear Agreement

While shared ownership can create opportunities, it can also create risks if the arrangements are not properly documented from the outset.

Unfortunately, people often focus on the excitement of purchasing a property and give little thought to what could happen in the future.

What happens if one owner wants to sell but the other does not?

What if one party contributes significantly more towards maintenance, improvements or mortgage repayments?

What happens if one owner experiences financial hardship or a relationship breakdown?

These situations can place considerable strain on personal relationships if there is no agreed process to follow.

A well-drafted Property Sharing Agreement can address these issues before they arise. Every arrangement will be different, but the agreement may cover matters such as:

  • Ownership shares
  • Deposit contributions
  • Mortgage repayment responsibilities
  • Rates, insurance and maintenance costs
  • Decision-making processes
  • Buy-out provisions
  • Sale procedures
  • Exit strategies

The goal is not to plan for failure. The goal is to ensure everyone understands their rights and responsibilities from the beginning.



Parents Helping Their Children into the Market

Shared ownership is also becoming increasingly common between parents and adult children.

Some parents choose to contribute funds towards a deposit. Others purchase a share of the property alongside their child or assist through lending and guarantee arrangements.

These structures can work extremely well, but they should always be carefully documented.

While no one enters these arrangements expecting family disputes, clear documentation protects everyone involved and helps avoid misunderstandings later.

Independent Legal Advice Matters

One of the biggest mistakes purchasers can make is assuming everyone involved has the same understanding of the arrangement.

Before entering into any shared ownership structure, each party should obtain independent legal advice.

This ensures that everyone fully understands the legal implications, the risks involved, and what will happen if circumstances change in the future.

A relatively small investment in getting the documentation right at the beginning can prevent significant costs and disputes later.

Thinking Outside the Box

For many New Zealanders, the idea of purchasing a home with someone other than a spouse may once have seemed unconventional.

Today, it is becoming an increasingly practical solution.

Home ownership does not always have to follow the traditional pathway. With the right advice, the right structure and appropriate legal protections in place, shared ownership can provide an effective stepping stone onto the property ladder.

If you are considering purchasing a property with family members, friends or other co-owners, speaking with a lawyer early in the process can help ensure the arrangement is structured correctly and protects everyone's interests.
