Buying a second property in Australia — whether as an investment, holiday home, or future home — involves different financial, tax, and borrowing considerations than your first purchase. In 2026, rising property values, tighter APRA lending standards, and land tax obligations mean the decision to purchase a second property requires careful planning. Here is what you need to consider before you buy.

Borrowing Power for a Second Property

Lenders assess serviceability for a second mortgage based on your total debt obligations — including your existing home loan, credit cards, and any HECS debt. APRA's 3% serviceability buffer means lenders test your ability to repay at approximately 9-10% in 2026, even if your actual rate will be lower. Key factors affecting your borrowing power for a second property:

  • Equity in your first property: Usable equity (typically 80% LVR minus the outstanding loan) can be accessed as a deposit for the second property
  • Rental income: For an investment property, lenders typically count 70-80% of expected rental income toward serviceability
  • Existing debts: Credit cards (assessed at 3% of the limit), car loans, HECS repayments all reduce available borrowing capacity
  • Debt-to-Income ratio: APRA's guidance caps DTI at 6-8x for new lending — factoring both properties

Tax Implications of a Second Property

Investment Property

If rented out, all rental income is assessable and all eligible expenses are deductible. Negative gearing losses offset your other income. When you eventually sell, CGT applies on the gain (with the 50% discount for assets held more than 12 months). Your primary home remains CGT-exempt while you occupy it.

Holiday Home / Personal Use Property

A holiday home you use personally provides no tax deductions while you occupy it. If you also rent it out periodically, expenses must be apportioned based on rental vs personal use days. You cannot deduct expenses for periods of personal use or periods when the property is not genuinely available for rent at market rates.

Land Tax on Second Properties

Your principal place of residence is exempt from land tax — but any second property you own (investment, holiday home, commercial) is subject to land tax at state rates. In NSW, the 2026 land tax threshold is approximately $1,075,000 in unimproved land value. In Victoria, the threshold is much lower at $300,000. Land tax is deductible for investment properties, not for holiday homes used personally.

Stamp Duty on a Second Property

Stamp duty concessions for first home buyers do not apply to second property purchases. Full stamp duty rates apply. In NSW, stamp duty on a $900,000 second property is approximately $36,000. Victoria applies an additional 1% "absentee owner surcharge" on investment properties owned by non-residents of the property.

Frequently Asked Questions

Can I use equity in my home to buy an investment property?

Yes. Usable equity — typically the difference between 80% of your home's value and your outstanding loan — can be accessed by refinancing or through an investment loan secured against your home. The interest on the portion used for the investment property is fully deductible. The interest on your home loan remains non-deductible.

Do I pay CGT when I sell my second property?

Yes. A second property that has not been your main residence is fully subject to CGT. The 50% CGT discount applies if you owned it for more than 12 months. The gain is calculated as: sale price minus cost base (purchase price, stamp duty, improvement costs, and selling costs).

How much deposit do I need for a second property?

Most lenders require a minimum 20% deposit for a second investment property to avoid LMI — or 10% with LMI. You can use equity from your existing home as the deposit, avoiding the need to save cash separately. Speak to a mortgage broker to understand the most cost-effective structure for your situation.
