What separates successful investments from disappointing ones is understanding the complete tax and finance picture before you build.
This guide breaks down tax deductions you can actually claim, finance options that work for granny flat investment property Victoria builds, and the real numbers driving returns in Melbourne’s 2026 market.
Tax Benefits: What You Can Actually Claim
The tax advantages of granny flat investment property Victoria builds are substantial when structured correctly. Understanding what the ATO allows helps you maximise after-tax returns.

- Blinds and window furnishings: 5 years
Total annual depreciation (typical $230,000 build):

- Total: $9,250-$10,250/year
Tax benefit (37% bracket): $3,422-$3,792/year

- Repairs and maintenance (ongoing, not improvements)
- Council rates (proportional to granny flat)
- Landlord insurance premiums
- Advertising for tenants

Example annual deductions ($230,000 build, $500/week rent):
| Expense | Annual Cost | Tax Deductible |
|---|---|---|
| Loan interest (6.5% on $184k) | $11,960 | Yes |
| Property management (8%) | $2,080 | Yes |
| Insurance | $500 | Yes |
| Maintenance | $1,150 | Yes |

| Fixtures depreciation | $3,500 | Yes |
| Total deductions | $25,440 | Yes |
Tax benefit (37% bracket): $9,413/year
Negative Gearing: How It Works
When deductions exceed rental income, you’re negatively geared. The ATO lets you offset this loss against other income, reducing your overall tax.
Example:
- Rental income: $26,000
- Deductions: $25,440
- Net income: $560
- Result: Near-neutral gearing with capital growth potential
Many investors structure for slight negative gearing in early years, transitioning to positive cashflow as rents increase and loan principal reduces.
Capital Gains Tax (CGT) Considerations
When you eventually sell:
- CGT applies to profit on granny flat portion
- Hold 12+ months: 50% CGT discount applies
- Only pay tax on half the capital gain
- Main residence exemption doesn’t apply to granny flat
Example sale scenario (10 years):
- Build cost: $230,000
- Sale value: $320,000
- Capital gain: $90,000
- Taxable (50% discount): $45,000
- Tax (37% bracket): $16,650
- After-tax profit: $73,350
Important: Seek advice from qualified tax professionals on your specific situation.
