Many Australian homeowners eventually decide to move out of their family home and rent it to tenants. Whether you’re upsizing, relocating for work, moving in with a partner, or purchasing a new principal place of residence, converting your former home into an investment property can have significant Capital Gains Tax (CGT) implications.
One of the most important steps property owners often overlook is obtaining a valuation when the property first becomes income-producing.
A professional CGT valuation can provide valuable evidence for future tax calculations and potentially save thousands of dollars when the property is eventually sold.
What Happens When You Turn Your Home Into an Investment Property?
When a property that was previously your principal place of residence begins generating rental income, its tax treatment changes.
From this point forward, you may be able to claim deductions for:
- Interest on investment loans
- Property management fees
- Council rates
- Insurance
- Repairs and maintenance
- Depreciation and capital works deductions
However, you may also become subject to Capital Gains Tax when the property is eventually sold.
This is where obtaining a valuation becomes important.
Why Is a CGT Valuation Important?
A valuation establishes the property’s market value at the time it first becomes an investment property.
This provides a record of the property’s value at a critical point in time and can assist accountants and tax advisers when calculating future capital gains.
Many property owners assume they will remember what the property was worth years later. Unfortunately, by the time the property is sold, market evidence from that period may be difficult to locate and substantially less reliable.
Obtaining a valuation at the time of conversion creates a clear and defensible record that can be relied upon in the future.
The Six-Year Absence Rule
One of the most valuable tax concessions available to Australian homeowners is the “six-year rule.”
Under certain circumstances, property owners can move out of their home and continue treating it as their main residence for Capital Gains Tax purposes for up to six years while it is rented out.
This means a property can potentially generate rental income while still qualifying for a full CGT exemption.
However, the rules are complex and depend on factors such as:
- Whether another property is nominated as your main residence;
- How long the property is rented;
- The dates of occupancy and vacancy; and
- Individual ownership circumstances.
Because these rules can significantly affect future tax outcomes, maintaining accurate valuation records is highly recommended.
When Is a Valuation Required?
A valuation is commonly obtained when:
You Move Out and Rent the Property
The most common scenario occurs when a homeowner moves into a new residence and leases their former home to tenants.
The Property Begins Producing Income
The relevant date is typically when the property first becomes available for rent or is first rented to tenants.
A Future CGT Calculation May Be Required
Even if you do not plan to sell for many years, obtaining a valuation at the time of conversion can provide valuable evidence if the property’s tax treatment is ever reviewed.
Can You Obtain a Valuation Later?
Yes.
If a valuation was not obtained when the property first became an investment property, a retrospective valuation may be possible.
A qualified valuer can often determine the property’s market value as at the relevant historical date using:
- Historical sales evidence;
- Archived property records;
- Market conditions at the time; and
- Comparable sales data.
However, obtaining a valuation at the time of conversion is generally easier and may provide stronger supporting evidence.
What Does a Valuer Consider?
When preparing a CGT valuation, a Certified Practising Valuer may assess:
Comparable Sales
Properties sold around the valuation date that are similar in location, land size, condition, and improvements.
Property Improvements
Renovations, extensions, pools, landscaping, and other features that influence market value.
Land Characteristics
Land size, zoning, frontage, views, and development potential.
Property Condition
The condition and presentation of the property at the relevant date.
Market Conditions
Supply, demand, interest rates, and local property market activity at the time.
The valuation report then provides an independent assessment of the property’s market value as at the required date.
Common Mistakes Property Owners Make
Not Obtaining a Valuation
Many owners only discover they need a valuation when they decide to sell years later.
Relying on Online Estimates
Online property estimates may not satisfy ATO requirements and often lack supporting evidence.
Assuming the Main Residence Exemption Covers Everything
The six-year rule and main residence exemption can be extremely beneficial, but they do not automatically eliminate every CGT issue.
Losing Historical Records
Property owners frequently lose documentation relating to renovations, improvements, and historical values that may affect future CGT calculations.
How Much Can a Valuation Save?
Every property owner’s circumstances are different.
For properties that have experienced significant capital growth, accurate valuation records can play an important role in ensuring capital gains are calculated correctly and supported with appropriate evidence.
The cost of a professional valuation is often relatively small compared to the potential tax consequences of an unsupported or inaccurate CGT calculation.
Converting your home into an investment property is one of the most common property strategies used by Australian homeowners.
While many owners focus on rental income and tax deductions, it is equally important to consider the long-term Capital Gains Tax implications.
Obtaining a professional valuation when the property first becomes income-producing can provide valuable evidence, support future tax calculations, and help avoid complications years later when the property is sold.
If you are planning to rent out your former home, speaking with both your accountant and a qualified property valuer before the property is leased can help ensure you have the right documentation in place from the start.
