“Is this good cash flow?” feels like it should have a numerical answer, the way a good rental yield gets framed around a percentage band. It does not — and pretending otherwise is how investors end up holding a property they cannot afford or dismissing one that would have served them well. Good cash flow is defined by fit, not by a figure.
Why there is no single good number
A property that costs $100 a week to hold is a problem for an investor stretched to their limit and a rounding error for one with strong income chasing capital growth. A property that clears $150 a week positive is a triumph for an income-focused retiree and a sign of a low-growth area to someone building long-term wealth. Same numbers, opposite verdicts.
This is why Akweno reports your actual weekly position rather than grading it. The figure is objective; whether it is “good” is a judgement only you can make against your strategy and your budget.
Good means sustainable, not just positive
The most useful reframing is to stop asking whether cash flow is positive and start asking whether it is sustainable — whether you can carry this position not just today but through a rate rise, a vacancy, or the year a major repair lands. A property that is slightly positive today but would tip you into distress if rates moved a percent is not in good shape.
A helpful lens: good cash flow is a position you could still hold comfortably if interest rates rose 2%, the property sat empty for a month, and a $5,000 repair arrived — all in the same year. If that scenario would force a sale, the current number is flattering you. The cash flow buffer guide turns this into a practical test.
What good looks like by strategy
Income investor
Good means clearly and reliably positive after all costs and tax — the property is meant to pay you now, so a break-even result is underperforming.
Growth investor
Good means a manageable negative you can comfortably fund from other income, accepted deliberately in exchange for capital growth potential.
Accumulator (building a portfolio)
Good means neutral-to-slightly-negative that does not consume the serviceability you need to borrow for the next property. Every extra dollar out is a dollar of future borrowing power spent.
Near retirement / deleveraging
Good means positive and growing as debt reduces — cash flow that will replace employment income, so the trajectory matters as much as today's figure.
Notice that the same property can move between these boxes as your own circumstances change. “Good” is not a property attribute — it is the match between the property and where you are. This is the essence of sustainable cash flow.
The real test: can you hold it?
Strip everything back and good cash flow answers one question: can you comfortably hold this property long enough for the strategy to work? Property rewards time in the market, and the investors who lose are usually those forced to sell at the wrong moment because the holding cost outran their budget. A “good” cash-flow position is one that lets you stay the course.
- Against your budget: the weekly out-of-pocket amount fits your surplus with room to spare, not to the last dollar.
- Against your other holdings: the combined drain across every property is one you could carry if a couple went vacant at once.
- Against the future:the position improves over time as rents rise and, on a P&I loan, debt falls — rather than relying on everything staying still.
When cash flow is genuinely bad
For all the nuance, some cash-flow positions are simply bad regardless of strategy:
- A negative position you can only fund by taking on more debt or dipping into savings you cannot replace.
- A result that only looks acceptable after the tax refund — the property is loss-making and depending on the deduction to disguise it.
- A positive figure achieved by deferring maintenance the property genuinely needs, which simply moves a larger cost into a future year.
- A position with no margin — any rate rise, vacancy or repair pushes you into selling.
