If you’re considering building an investment property, understanding how construction loans work and the tax benefits available can make a substantial difference to your finances. In Australia, construction loans offer unique flexibility by allowing progressive drawdowns, which means you’re only paying interest on funds as they’re needed during each stage of the build.
In this post, we’ll cover the essentials of construction loans for investment properties, explore how these loans work, and clarify the tax implications you should know as an investor.
Can you get a construction loan for an investment property?
Yes, you can use a construction loan to build an investment property in Australia. While construction loans are commonly associated with owner-occupied homes, they can also be used for investment properties. These loans function similarly to regular home loans but with some added features that cater specifically to the construction process.
Construction loans generally offer interest-only payments during the building phase, which can help ease the financial burden until the property is complete and generating rental income. Once construction is finished, the loan often reverts to a standard principal and interest repayment structure.
However, because investment properties may pose slightly more risk to lenders, you can generally lend no higher than 90% of the total value of the completed build.
How does a construction loan work?
A construction loan in Australia works by allowing you to draw funds progressively at various stages of construction rather than receiving the entire loan amount upfront.
Typically, a construction loan is divided into the following stages, which align with the different stages of building/construction:
- Laying the Foundation (Slab Down)
- Frame Up
- Lock-Up Stage (Doors and Windows Installed)
- Fixing Stage (Interior Finishing)
- Completion
At each stage, you’ll provide an invoice from the builder to your lender, who will release funds for that phase. This means you’re only paying interest on the money you’ve drawn down, making it more cost-effective during the construction phase.
This “progressive drawdown” structure reduces your interest payments initially, and the interest-only option during construction helps maintain cash flow, which can be beneficial if you’re waiting for the property to generate rental income.
Can you claim construction loan interest on your taxes?
According to the Australian Taxation Office (ATO), the ATO allows investors to claim the interest paid on a construction loan for an investment property as a tax deduction.
However, it’s essential to note that you can only claim this interest once the property is actively generating income. According to ATO guidelines, deductions for vacant land are limited, meaning you cannot claim interest if the land is vacant and not available for rent.
For investment properties, interest expenses on construction loans are typically deductible, provided the property is intended to be leased out and is not used for personal purposes.
As of recent ATO rulings, the interest paid on the construction loan becomes tax deductible as soon as the property is available for rent, even if it is not yet occupied.
Are construction loans tax deductible in Australia?
While the loan principal is not tax deductible, the interest payments on a construction loan for an investment property generally are, provided the loan is solely for income-producing purposes. The ATO specifies that interest is only deductible if the loan directly finances the construction of an income-generating property.
This means that you cannot claim a tax deduction on a construction loan used for a personal residence or on vacant land that is not yet available to rent.
For example, if you’re building a rental property, the interest on your construction loan can be deducted from your assessable income, reducing your overall tax liability.
However, if you change your plans and decide to occupy the property yourself, the tax deductibility of the interest will be impacted. Similarly, if you refinance the loan for personal reasons, you may lose the deduction eligibility.
Please note that any information above relating to the Australian Taxation Office (ATO) and tax deductions is general in nature and you should always seek advice from your accountant, financial advisor or other professional when making decisions about your tax and investment position.

Important Considerations for Investors
When it comes to construction loans and tax deductions, there are a few additional points to keep in mind as an investor:
- Interest Deductibility Begins with Rental Availability: You can only claim interest deductions from the date the property is available for rent, even if it’s not immediately occupied.
- Cost of Holding Vacant Land: Since 1 July 2019, the ATO restricts deductions for the cost of holding vacant land. This means you cannot claim expenses like council rates or loan interest for vacant land unless it is being actively developed for an income-producing purpose.
- Amending Past Returns: If you recently built an investment property and haven’t claimed interest deductions, you may be able to amend past tax returns within a two-year window. It’s best to consult a tax professional or other financial advisor to ensure compliance with ATO guidelines and to provide tailored advice for your situation.
Navigating construction loans and tax deductions
Construction loans are a powerful tool for investors looking to build rental properties, providing the flexibility to pay interest only on drawn-down funds and to manage cash flow effectively during the build.
Understanding how these loans work, along with the tax deductions available, can help maximise your investment’s profitability.
Before committing, it’s wise to speak with both your lender and a tax advisor to fully understand the loan terms and tax implications. Being well-informed about how construction loans and tax deductions work can make a significant difference in your financial planning and help ensure that you’re taking full advantage of the benefits available to property investors in Australia.
