The short answer: Model net sale proceeds against conservative after-tax rental cash flow, then add the family's need for flexibility. Get tax advice before the residence change or sale contract, ask the lender and insurer about overseas residence, and appoint a properly authorised local manager if the home stays.
Price the sale using net proceeds, not the listing figure
Start with a current market appraisal, then subtract mortgage discharge, agent commission, marketing, conveyancing, repairs, removal and any tax. Check fixed-rate break costs and settlement timing. Decide where proceeds will be held, how currency will be converted and whether moving the money affects destination reporting or tax.
The tax result can change if the owner is a foreign resident when the contract is signed. A foreign resident generally cannot claim the Australian main-residence exemption unless the limited life-events test applies, even where the former six-year absence rule might otherwise appear helpful.
Understand the withholding process before listing
For contracts signed from 1 January 2025, foreign-resident capital gains withholding applies at 15% to taxable Australian real property regardless of value. An Australian-resident seller generally obtains an ATO clearance certificate and gives it to the purchaser before settlement so withholding is not required. A foreign-resident seller can seek a variation in appropriate circumstances.
The amount withheld is a credit against the seller's final Australian tax assessment, not necessarily the capital gains tax itself. Build the settlement cash-flow plan early; discovering the clearance or variation process after exchange can create avoidable pressure.
Worth knowing: Residence, CGT exemption and withholding are separate questions. A clearance certificate addresses purchaser withholding; it does not decide the final capital gain or exemption.
Model renting as a remote business
Australian rental income generally remains reportable in Australia for a non-resident owner. Use a realistic rent and deduct vacancy, management, letting fees, repairs, compliance, insurance, rates, land tax, interest and a reserve for major work. Capital works and depreciation need records and can affect the eventual cost base.
State and territory tenancy, safety, land-tax and licensing rules differ. Choose an appropriately licensed manager, agree authority and spending limits, and decide who handles urgent repairs, insurance claims, strata, tax records and legal notices. Keep one Australian contact who can act when time zones or identity checks slow you down.
- Get written lender consent or confirmation for the intended use and overseas correspondence.
- Replace owner-occupier cover with suitable landlord and building insurance before a tenant enters.
- Confirm vacancy, unoccupancy and overseas-owner exclusions with the insurer.
- Budget for state land tax and any absentee-owner surcharge that applies to the owner and jurisdiction.
- Schedule inspections and store condition reports, invoices and tax statements digitally.
Value the return option honestly
A retained home can make a return feel safer, but a tenanted property may not be available at short notice. The family may return to a different school, work or care geography, while the property continues to consume borrowing capacity and management attention.
Selling removes those obligations and can strengthen the relocation reserve, but re-entering the Australian market later may be expensive. Compare the home with the investment and life choices the same equity could fund rather than treating familiarity as a financial return.
Keep tax and property records for the full ownership period
Retain the purchase contract, stamp duty, legal costs, capital improvements, first-use valuation where relevant, loan statements, depreciation schedules, rental accounts, sale documents and tax advice. Records may be needed years after the move.
Review the decision annually. Tax residence, destination plans, interest rates, insurance, tenant performance and the family's likelihood of return can all change the better answer. A deliberate sale later is different from a forced sale during a cash-flow problem.
A fair rent-versus-sell comparison
Use the same time horizon and after-tax basis for both sides. Avoid comparing optimistic rent with gross sale price.
| Factor | Sell now | Keep and rent |
|---|---|---|
| Cash | Net proceeds after debt, costs and tax | Rent after vacancy, costs, tax and reserves |
| Tax | CGT, exemption eligibility and withholding process | Annual Australian return, deductions and later CGT |
| Risk | Re-entry price and currency timing | Tenant, repairs, rates, finance and regulation |
| Insurance | Cover until settlement and vacant periods | Landlord, building, liability and overseas-owner terms |
| Flexibility | Liquid capital but no guaranteed home | Asset retained but not necessarily immediately available |
| Workload | Sale preparation and one transaction | Ongoing manager, records, approvals and review |
