What Is An Owner-Builder Loan In Australia?

An owner-builder loan is a type of construction loan designed for borrowers who plan to manage or complete the construction of their own home rather than use a licensed builder.

Unlike standard construction loans:

• Fewer lenders offer them
• Stricter lending criteria apply
• Lower borrowing limits are common

How Much Can I Borrow As An Owner-Builder?

Your borrowing capacity depends on your experience, licence status and overall risk profile.

• Borrow up to 80% of the project cost if you’re a licensed builder building your own property (on a case-by-case basis).
• Borrow up to 70% of the project cost if you’re not a licensed builder.
• Borrow up to 100% of the land and construction costs with some of our lenders if you have a guarantor.

How To Qualify For An Owner-Builder Loan

Lenders assess several factors when deciding whether to approve an owner-builder loan. In most cases, they look for:

• Enough funds to cover unexpected cost overruns
• The required insurance, permits, and council or government approvals
• Equity in the land, genuine savings, or other acceptable security
• A clear and realistic plan for completing the build

If you already own the land, you can release equity to fund the construction instead of applying for a standard owner-builder loan. This can be a simpler option in some situations.

Most banks prefer to finance homes built by licensed builders, so owner-builder loans are usually only available through a smaller group of lenders.

What Documents Do I Need For An Owner-Builder Loan?

As an owner builder, you’ll need to provide more documents than a traditional borrower:

• Building plans/floor plans.
• An itemised estimate of the total cost of construction.
• A copy of your owner-builder insurance (if applicable).
• Evidence that you are using the Home Building System (if applicable).
• A copy of your owner-builder permit (if applicable).

Once you have obtained council approval, you’ll be required to provide a copy of the council-approved plans to the lender.

How Are Owner-Builder Loan Funds Advanced?

Unlike a traditional home loan, the lender won’t pay you all of the loan funds when the loan is set up. Instead, they’ll release funds to you as construction progresses. This is known as ‘progress payments’ or ‘construction draw downs’. Once you have completed each step of construction, a bank valuer will be sent out to assess your work, confirm you have followed the floor plans and then authorise the bank to make the next payment.

If you have a large equity in your land, we can arrange a line of credit based solely on its value. This will allow you to build your new home without the lender having to monitor your progress. This is usually available when you’re borrowing no more than 80% to 90% of the land value alone.

What Type Of Building Licence Do You Need For An Owner-Builder Loan?

There are many types of building licenses, each with its own restrictions. The lenders we work with for owner-builder finance tend to prefer borrowers with an unlimited building license rather than a project management license. If you have an unlimited building license, you’ll have a better selection of lenders to work with. Of course, if you don’t have a building licence at all, you’re still eligible for an owner-builder loan, but you’ll need a larger deposit.

Special Owner-Builder Scenarios

Some owner-builder situations do not fit standard lending policy. This usually applies when you are building multiple dwellings, applying for a low-doc loan, financing a partially completed property, or using a guarantor to increase your borrowing power. These scenarios are more specialised, so the lending rules are stricter, and fewer lenders are available.

Small Developments

Some lenders can assist with small development projects, which may suit builders taking their first step into property development. This option is generally for projects of up to 4 dwellings, such as duplexes, townhouses, or small-unit developments, with loan amounts up to $1,500,000.

Depending on the project, you may be able to borrow up to 70% of the Gross Realisation Value (GRV), which is the expected end value of the completed development, or up to 80% of the hard costs, which usually means the land value plus construction costs. In some cases, lenders do not require proof of income if the plan is to sell the properties once construction is complete. For smaller projects, presales may not be required. Once the project is finished, you can sell the properties or refinance some of them onto standard investment or low-doc loans and keep them.

Low Doc Owner Builder Loans

Low-doc owner-builder loans are available only in limited situations and are usually only for licensed builders. These loans are most relevant when a licensed builder is completing a small development of their own and cannot provide full income verification.

For this type of loan, finance may be available for up to four dwellings with a maximum loan amount of $1,500,000. Borrowing is generally capped at the lower of 70% of the GRV or 80% of the hard costs. If you are not a licensed builder, we generally cannot assist with low-doc construction finance. However, in some cases, a low-doc loan may still be available against the land value or other property you already own, with the option to review the loan again once construction is complete.

Partially Completed Homes

Partially completed owner-builder homes are very difficult to finance. Most lenders will not accept an incomplete property as security, which is why it is usually best to apply for finance before construction starts or after the home is fully completed.

If you have already started building and need more funds, lending may still be possible in limited situations. The maximum loan amount depends on the type of project:

• up to 60% of the total cost for an owner-builder
• up to 75% if you are a licensed builder building your own home
• up to 80% for standard construction with a licensed builder

Using A Guarantor With A Construction Loan

A guarantor can help you borrow more than a standard policy would normally allow. If a family member or close relative is willing to provide additional security, you can borrow more than 80% of the total project cost and, in some cases, up to 100%.
