In this final instalment of the three-part cash flow series, Damien and Jeremy bring in mortgage broker Alana, from We Mortgage Solutions, to address a key question: does owning cash-flow-neutral or positive property mean an investor can keep buying indefinitely without running into lending limits?
Is There a Ceiling on Accumulating Cash Flow Positive Properties?
Alana confirms there is a real, practical ceiling. Using an example of an investor earning $85,000 a year, living rent-free at home with minimal existing debt, she estimates it's realistically possible to acquire up to around six cash-flow-positive properties (at roughly $350,000 each, 80% LVR, requiring around a 8%+ yield, roughly $580 a week in rent per property, to remain cash flow positive) before hitting a serviceability ceiling and needing to turn to alternative lenders at meaningfully higher rates (she cites 8–9%). She stresses this isn't something that happens quickly, since achieving that level of rent on a $350,000 property takes time, and in her experience, very few clients actually reach five or six properties at this price point, partly because cheaper properties often come with lower tenant quality, higher property management costs, and higher maintenance expenses, adding administrative burden without necessarily justifying the extra complexity compared to holding a smaller number of higher-quality properties.
Alana also notes some lenders apply specific restrictions or reduced rental income allowances (for example, counting only 80% of stated rent) in postcodes they consider higher risk, sharing an example of a recent client purchasing in Rockhampton at the $350,000 price point currently earning only $410 a week rent, well short of the level needed for cash flow neutrality, illustrating that even with patience and a willingness to add value (such as a bathroom or kitchen renovation, or improving outdoor entertaining space to suit the local climate), reaching a genuinely cash-flow-positive position can take considerable time.
How Do Investors With 20–30+ Properties Actually Get There?
Asked how some investors manage to accumulate portfolios far larger than what typical serviceability would allow, Alana explains this is rarely achieved through employment income alone. Common pathways include purchasing through a trust structure, where some lenders will accept an accountant's letter or self-declaration confirming a property is cash flow positive, excluding that loan from standard serviceability calculations, though this generally applies to only a small number of lenders. She notes trust structures come with added costs (legal advice, accounting fees, tax return complexity) and different land tax thresholds (for example, in New South Wales, roughly $600,000 for individually held land versus $350,000 for land held in a trust or corporation), which need to be factored into the overall cost-benefit of that structure.
Jeremy shares his own frustration with social media portrayals of extremely young investors claiming large portfolios, noting that in his own experience working closely with clients over many years, the largest genuine portfolio he encountered was around 10 properties, typically held by someone much closer to retirement, and often including several underperforming assets. His view is that very large portfolios are usually funded by a highly profitable separate business (which can support significantly higher lending capacity even without fully distributing profits as personal income) rather than accumulated purely through property cash flow or standard employment income, a distinction he feels is rarely disclosed by those publicising large portfolios online. Alana confirms lenders can factor in a business's retained net profit for serviceability purposes even when it isn't distributed, supporting her observation that established business owners are often in a stronger borrowing position than employees.
So, Will You Ever Hit a Serviceability Wall?
Jeremy's direct answer: yes. Based on years of experience working with clients, there's always a practical ceiling, driven primarily by employment or business income available for serviceability, not by how cash-flow-friendly the properties themselves are. His advice to listeners hearing claims of unlimited, rapid property accumulation online: be sceptical, and ask specifically how that outcome was actually achieved.
Granny Flats, Room-by-Room Rentals, NDIS, and Airbnb
Jeremy shares that his own first two properties both included granny flats, motivated at the time by a strong cash-flow-first mindset, though he's since shifted his overall philosophy toward prioritising capital growth. He shares that he later considered adding a granny flat to another property (at an estimated cost of around $150,000 at the time) but ultimately decided against it, since it would have constrained a future subdivision or redevelopment option on that block. A guest contributor, Adam, notes granny flats today typically cost upwards of $180,000 for a standard 60 sqm build, plus potential council fees that can exceed $10,000 depending on the local government area, suggesting this can be a reasonable way to deploy a smaller amount of capital (for example, if lending for another full property isn't currently available) to add a cash flow stream, though Jeremy notes that if full lending capacity is available, allocating that same capital toward a deposit on a separate property is usually the better option.
On renting by the room, Jeremy flags higher turnover and vacancy risk (co-tenants who don't know each other, more bathrooms typically needed, and property managers sometimes reluctant to take on the added complexity) as key downsides. On Airbnb specifically, both hosts caution that occupancy is rarely consistent (Damien shares an example of a Canberra-area unit client achieving good cash flow at around 60% annual occupancy, factoring in both personal use and paying guests), and that lending for a first property specifically as an Airbnb can be more difficult, generally more suited to an already-established portfolio or a genuinely tourist-heavy location rather than a typical suburban property. Damien also clarifies that Airbnb income is taxable like any other rental income, and that periods of personal use alongside rental use can complicate capital gains treatment at sale, worth discussing directly with a tax accountant.
On NDIS-specific property, Jeremy shares a past client experience involving a fixed rental guarantee that was expected to eventually taper off, alongside oversupply concerns in some NDIS-heavy markets at the time, and states he personally wouldn't invest in this category without being confident in the underlying capital growth case, rather than treating a rental guarantee alone as sufficient justification.
Alternatives to Property for Pure Cash Flow
Jeremy runs through a range of non-property options investors might consider if cash flow, not growth, is the specific goal: dividend-paying shares, cryptocurrency staking, car-sharing platforms, and even niche examples like vending or ATM machine ownership (drawing on a past client example). His broader point: if property doesn't suit an investor's cash flow needs, there's no requirement to force a high-yield property purchase, other asset classes can provide income without the administrative load or accumulation-phase cash flow drag that a negatively geared property involves.
Both stress the value of broader asset diversification, even for investors who prefer property as their primary asset class, holding a smaller allocation to shares, cash, or other liquid assets provides flexibility that an all-property portfolio doesn't, given property can't be partially liquidated the way shares can.
Managing Debt and Cash Flow Surplus
Jeremy shares his own approach to surplus cash flow: rather than aggressively paying down debt to zero, he prefers keeping funds accessible in an offset account, preserving flexibility in case of job loss or another opportunity, rather than being left with no accessible cash if a loan is fully paid down. Both note that for many investors, more substantial debt reduction naturally occurs later via superannuation access at 60, rather than needing to be aggressively front-loaded during the accumulation phase, and flag this as a topic for a future dedicated episode.
Risks of an Overly Yield-Focused Approach
Summarising the series, Jeremy reiterates that an excessive focus on cash flow ultimately narrows the pool of viable markets so much that it limits access to genuine capital growth opportunities, in his view, counterintuitively slowing an investor's path to a genuinely retirement-ready portfolio compared to a more growth-focused approach.
Is Positive Cash Flow Property Right for Every Investor?
Jeremy suggests that, in his view, relatively few investors are actually well suited to specifically pursuing cash-flow-positive property, since it depends heavily on individual life stage. For someone in the accumulation phase, growth typically matters more; for someone at or near retirement genuinely needing income, cash flow becomes a more central consideration.
What Would Jeremy and Damien Each Do?
Jeremy states that even heading toward retirement, he would personally still prioritise growth over cash flow, viewing periodic capital growth (realised through occasional sales) as a form of "lumpy" cash flow rather than needing consistent week-to-week income from every asset. He notes he would only consider selling a property specifically if its growth outlook had genuinely weakened, reallocating that capital into a stronger-performing market, and cautions that a significant capital gain can meaningfully affect tax outcomes (potentially reaching the top marginal rate) in the year it's realised, worth planning around carefully.
Damien shares his own specific plan for his next purchase: a $750,000 property with a comparatively low yield (around 3.7%), costing him an estimated $266 a week to hold, deliberately prioritising capital growth given his existing asset base and personal comfort with that risk. Jeremy calculates this results in an estimated ROI of around 28.6%, notably higher than the "bog standard" roughly 16% ROI example modelled in Part 1, precisely because Damien is willingly sacrificing cash flow in pursuit of stronger growth. Damien notes that if he were earlier in his journey with less established cash flow buffer, he might lean toward a somewhat higher yield for his very first purchase, but given his current position, continues to prioritise growth.
Closing Thoughts
Both hosts close the series with a consistent message: balance cash flow, capital growth, and overall asset allocation according to personal circumstances, and avoid taking any single source (including their own commentary) as gospel, doing independent research remains essential.
