An SMSF can own a valuable property and still struggle to pay a bill. Liquidity means having cash or assets that can be converted into cash when obligations fall due. Rental income may arrive monthly, while rates, insurance, repairs and benefits fall at different times. A forecast needs to show that timing, not just an annual surplus.
Use our SMSF accountant introduction service to find an independent specialist for fund-specific planning. The aim here is to prepare questions, not prescribe a reserve amount. For strategy considerations alongside cash flow, see reviewing an SMSF investment strategy before buying property.
Separate acquisition cash from ongoing reserves
Start with the deposit, remaining settlement contribution and purchase costs. Ask the conveyancer and advisers to estimate duty, professional fees, inspections and any structure costs relevant to the transaction. Then identify what liquid funds remain after settlement, rather than counting the same cash as both the purchase contribution and a reserve.
Include ongoing property costs and fund administration costs separately. Management fees, insurance, rates, strata levies where applicable, accounting, audit, tax and loan commitments may all need funding. A property appraisal or loan approval is not a complete budget for the fund.
Build a month-by-month forecast
- List expected rent receipts and when the property is actually likely to be available for occupation.
- Identify each member's expected contributions, with timing and assumptions confirmed rather than treated as guaranteed.
- Schedule recurring bills, annual expenses, debt repayments and planned benefit payments.
- Include known repairs and ask how unexpected work would be funded lawfully.
- Show the closing cash balance each month, not only the year-end total.
- Mark which other assets could be sold and how long realisation might take.
Test several things going wrong together
A hypothetical scenario could combine a vacant property, an unexpected repair and lower contributions after a member stops work. Model these events in the same months. Testing each one separately may miss the period when cash is tightest. Use clearly labelled assumptions rather than an unsupported promise about likely vacancy or repair costs.
Also ask what happens when an interest-only period ends, if variable loan repayments rise or if a special levy is announced. A forecast should distinguish money already available from amounts dependent on a future sale, contribution or borrowing approval.
Do not assume personal cash can fill every gap
An SMSF is separate from its members. Contributions are subject to eligibility, acceptance and cap rules, and borrowing is restricted. Paying a fund's costs personally or advancing money can have consequences. Ask the accountant before moving funds, and coordinate with the lender or lawyer if an existing borrowing arrangement is involved.
There is no single cash reserve percentage that suits every fund. The appropriate discussion depends on liabilities, member needs, asset mix and risks. The ATO requires consideration of liquidity and the ability to meet obligations; it does not turn a generic property buffer into personalised advice.
Make the plan operational
Agree who checks actual receipts against the forecast, how trustees are alerted to a shortfall and when the strategy must be revisited. Save revised forecasts and the decisions behind them. Monitoring after settlement is as important as the initial calculation.
A liquidity misconception
Can the property's rising value pay the fund's bills?
Not without a lawful transaction that produces available cash. A valuation is not a bank balance, and selling or financing an asset can take time and involve restrictions and costs. Ask specialists to test the cash available on the dates payments are due.
