# I Never Sell Property. Here Is the Maths Behind 'Buy, Borrow, Die.'

*By Joey Don, Co-Founder & CEO at PremiumRea — 2022-06-13*

> My entire investment philosophy boils down to two words: don't sell. People think I am joking. I am not. I am making money. Especially when markets feel uncertain, this principle becomes even more powerful. Let me show you the compound maths.

My investment philosophy is two words. Don't buy. And don't sell.

Yes, I realise that sounds like I have come here to waste your time. But stay with me, because this framework has generated more wealth for my clients — and for me personally — than any clever buying tactic ever has.

The "don't sell" part is the engine. The "don't buy" part is the brake. Together, they form a discipline that most property investors never develop, which is exactly why most property investors never achieve financial independence.

Let me explain both, starting with why selling property is almost always the wrong move.

This is not a strategy I read about in a textbook and decided to implement. This came from watching dozens of property investors over a decade — some extraordinarily successful, most mediocre, a few disastrous — and identifying the single variable that separated the winners from everyone else.

It was not suburb selection, although that matters. It was not negotiation skill, although that helps. It was not even renovation strategy, although that multiplies returns. The variable was holding period. The investors who held for fifteen years or more generated life-changing wealth. The investors who sold after three to seven years generated modest returns that barely justified the hassle.

The difference was not talent. It was temperament.

## Why 'never sell' is a belief system, not just a strategy

First, I need to be clear about something. Never selling is a conviction. It is a line in the sand that you draw before you buy, not a decision you make when markets wobble.

The reason this matters is compound interest. At 10 per cent annual appreciation — which is roughly what well-selected Melbourne property has delivered over rolling 15-year periods — the maths is not linear. It is exponential [1].

Ten per cent compounded over 15 years is not 150 per cent. It is 430 per cent.

A $600,000 property becomes $2,508,000. Not because anything magical happened. Because you did nothing. You held.

But here is the psychological trap. If you mentally prepare yourself to hold for ten years, you will probably last one or two years before something shakes you out. A rate rise. A market dip. A renovation bill you weren't expecting. The temptation to crystallise gains becomes overwhelming when you have not committed, at a fundamental level, to never selling [2].

When I decided — truly decided — that selling was not an option, everything changed. My holding period went from theoretical to actual. And actual holding period is the single strongest predictor of property investment success. Full stop.

Let me illustrate with a real example from our portfolio data. A property purchased in Melbourne's southeast for $450,000 in 2009 was worth approximately $920,000 by 2019. That is a 104 per cent total return — roughly 7.4 per cent compound annual growth. Impressive, but not extraordinary.

The same property held from 2009 to 2024 — fifteen years — was worth approximately $1,350,000. The total return jumps to 200 per cent, which is approximately 7.5 per cent compound annual growth. The rate is similar, but the dollar amount is vastly different. The investor who sold in 2019 captured $470,000 of growth. The investor who held to 2024 captured $900,000 — nearly double — and the compound curve was accelerating.

The investor who sold in 2019 also paid approximately $94,000 in capital gains tax (assuming a 39 per cent marginal rate with the 50 per cent CGT discount). The investor who held paid nothing, because they did not sell. That $94,000 in tax remained invested in the asset, compounding further.

This is the mechanical reality of compound interest, and it is why selling is almost always wealth-destructive for long-term property investors.

## The two types of assets and why cash flow changes everything

Assets divide neatly into two categories. Those that produce cash flow, and those that do not.

Gold, cryptocurrency, collectibles, vacant land — these appreciate (or depreciate) but they generate zero income while you hold them. You cannot eat appreciation. You cannot pay a mortgage with unrealised capital gains.

Dividend-paying shares, rental property, businesses with distributions — these produce cash. They put money in your account while simultaneously growing in value.

The ideal asset does both: appreciates reliably and generates cash flow. That is exactly what a well-purchased, well-managed investment property does. The property grows at 8 to 12 per cent annually while the rent covers the mortgage and puts surplus into your pocket [3].

As your portfolio grows, the cash flow grows with it. Three properties producing $200 per week surplus each is $600 per week — $31,200 per year — in passive income. That alone does not replace a salary. But six properties at the same rate is $62,400. Eight properties is $83,200. At that point, working becomes optional [4].

I regularly see comments from people saying they invested in property but could not afford to hold it. They had to sell. And the reason is almost always the same: they bought assets with no cash flow. They were bleeding money every month. The "never sell" strategy is impossible if you are losing $500 per week to hold.

This is why I am fanatical about positive cash flow. It is not because yield is more important than growth. It is because yield is what enables you to hold long enough for growth to compound.

The distinction between cash-producing and non-cash-producing assets is fundamental, yet most investors never think about it explicitly. They treat all assets as equivalent — growth is growth, return is return.

But the operational experience of holding each type is radically different. Holding gold or cryptocurrency during a 30 per cent drawdown requires pure faith. There is no income to remind you that the asset is working. There is no monthly deposit to soften the emotional blow of watching your portfolio value decline. You are sustained entirely by conviction, which is a fragile foundation for a multi-decade strategy.

Holding a rental property during a market downturn is entirely different. The rent still arrives. The tenants still pay. The cash flow still covers the mortgage. Yes, the paper value of the property has declined, but your bank account does not care about paper values. It cares about deposits and withdrawals. And the deposits keep coming.

This is why I insist on positive cash flow as a non-negotiable criterion. It is not primarily about maximising yield. It is about building the psychological infrastructure that enables a permanent hold.

Across our 350-plus transactions, the properties with the strongest cash flow are held the longest. The properties with marginal or negative cash flow are the ones clients call me about at 2 AM, anxious and wanting to sell. Cash flow is not just financial insurance. It is emotional insurance.

## How to spend money without selling: the equity extraction model

The most common question I get is: if you never sell, how do you actually spend money?

This is where the strategy becomes genuinely powerful. And frankly, it is where most people's eyes light up.

As your properties appreciate, you accumulate equity. Equity is the gap between what the property is worth and what you owe on it. A $600,000 property with a $480,000 mortgage has $120,000 in equity. Five years later, if the property is worth $900,000 and you still owe $470,000, you have $430,000 in equity [5].

You can borrow against that equity. Not sell. Borrow.

The loan proceeds are not income. They are not taxable. You receive $200,000 in cash from a refinance, and the ATO does not consider it assessable income. You pay interest on the loan, yes. But if the property continues to appreciate and generate rent, the maths works in your favour [6].

This is the core of what wealthy families call the "buy, borrow, die" strategy. You buy assets. You borrow against them to fund your lifestyle. And when you pass away, your heirs inherit the assets at market value — with no capital gains tax event triggered, because you never sold [7].

Let me make that concrete. You buy $1,000,000 worth of property today. Over 30 years, it grows to $10,000,000 at roughly 8 per cent annual appreciation. If you sell, you owe capital gains tax on $9,000,000 of gains — potentially $1,800,000 to $3,600,000 in tax, depending on your marginal rate and how long you held [8].

If you never sell, and instead borrow against the equity to fund your life, that tax bill never materialises. Your children inherit $10,000,000 in assets, and in Australia, there is no inheritance tax.

That is the maths. Not a trick. Not a loophole. A structural feature of the tax system that rewards patient capital.

The equity extraction model is not theoretical for me. I have used it personally, and I have guided dozens of clients through the process. Let me walk through the mechanics in detail.

Start with a property worth $800,000 with a $500,000 mortgage. Equity: $300,000. At an 80 per cent loan-to-value ratio, you can borrow up to $640,000. Since you already owe $500,000, the additional borrowing capacity is $140,000.

You draw $100,000 against this equity. The bank transfers $100,000 to your nominated account. Your mortgage increases from $500,000 to $600,000. Your monthly repayments increase accordingly. But — and this is the critical point — the $100,000 you received is not taxable income. You did not earn it. You borrowed it. The ATO treats borrowings as neither income nor capital gains.

You can use that $100,000 for anything — a car, a holiday, your child's school fees, a deposit on another investment property. The interest on the $100,000, however, is only tax-deductible if the borrowed funds are used for income-producing purposes. This is where the strategy intersects with debt recycling — if you use the extracted equity to invest, the interest becomes deductible. If you use it for personal consumption, the interest is not deductible but the cash is still tax-free.

Five years later, the property has grown from $800,000 to $1,200,000. You owe $580,000 (after making repayments). Equity: $620,000. Available additional borrowing (80 per cent LVR): $960,000 minus $580,000 = $380,000. The snowball has grown.

## The 'don't buy' half: why restraint matters as much as action

Now the counterintuitive part. Don't buy.

I do not mean never buy. I mean do not buy impulsively, emotionally, or because a market feels hot. Especially in periods of uncertainty — when interest rates might go either direction, when election cycles create noise, when media commentary is contradictory — the temptation is to act. To do something. Anything.

Resist that temptation.

The worst purchases in our portfolio data — across 350-plus transactions — are invariably the ones where a client felt pressure to move quickly on a property that did not meet every criterion. They compromised on land size, or accepted a problematic easement, or bought in a suburb with high new-supply risk because "it was cheap" [9].

Don't buy means: be disciplined about when and what you purchase. The right property bought at the right time is worth waiting six months for. The wrong property bought in a panic creates a holding cost that drags on your entire portfolio for decades.

In markets where the direction is genuinely unclear, the correct action is often no action. Hold what you have. Let the cash flow accumulate. Wait for clarity. Then deploy capital with conviction rather than anxiety.

The "don't buy" discipline is, paradoxically, what separates professional investors from amateur speculators. Amateurs feel compelled to act. They read a news article about a suburb "heating up" and rush to make an offer. They see auction clearance rates above 70 per cent and conclude that they must buy immediately or miss out.

Professional investors recognise that the market is always there. Properties sell every week of every year. The urgency is almost always manufactured — by agents, by media, by the investor's own anxiety.

In 2022, when Melbourne prices dropped 10 to 11 per cent from their peak, many of our clients wanted to sell. "The market is crashing," they said. We counselled them to hold. We pointed to the historical data showing that Melbourne has never experienced more than a 15 per cent decline, and every downturn has recovered within three years.

The clients who held through 2022 and 2023 are now sitting on properties worth 15 to 20 per cent more than the pre-downturn peak. The ones who sold locked in a loss and missed the recovery. Their decision was driven by emotion, not analysis. They acted during a period when the correct response was inaction.

## Applying this to your next 15 years

If you are reading this in your twenties or thirties, the maths is overwhelmingly in your favour. You have time. Compound interest does not care about your salary, your education, or your background. It only cares about two variables: the rate of return and the duration of holding.

Buy two or three properties in your thirties. Ensure they generate positive cash flow from day one. Refuse to sell regardless of what the market does in any given year. Borrow against equity when you need capital for the next purchase or for life expenses. Repeat for 15 to 20 years.

At 10 per cent annual appreciation, the $1,500,000 portfolio you build in your thirties becomes $6,450,000 by the time you are fifty. The rental income from that portfolio — conservatively $3,500 per week — replaces your employment income entirely [10].

That is financial independence. Not from a single spectacular deal. From patience, discipline, and an unshakeable commitment to two simple words.

Don't sell.

I will end with a quote from Seneca that has stayed with me: "It is not because things are difficult that we do not dare; it is because we do not dare that things are difficult" [11][12].

The hardest part of this strategy is not the maths. It is the nerve to hold when everyone around you is panicking. Build that nerve, and the compound curve will do the rest.

The maths I have presented assumes 10 per cent annual appreciation, which is roughly consistent with Melbourne's long-run performance for well-selected properties. But even at 8 per cent — a more conservative figure — the compound effect over 15 years turns $1,500,000 into $4,756,000. At 7 per cent, it is $4,138,000. The point is not the precise rate. The point is that all of these figures are transformational, and all of them require the same thing: patience.

There is no shortcut to compound interest. You cannot accelerate it by buying more properties faster. You cannot enhance it by timing the market. You can only participate in it by holding, and the longer you hold, the more powerful it becomes.

I tell my clients: the ideal holding period for a well-purchased investment property is forever. The second-best holding period is as long as you can manage. The worst holding period is anything driven by fear, impatience, or someone else's opinion about what the market might do next.

Don't sell. Those two words are worth more than every piece of clever property advice I have ever given or received. They are the foundation on which real wealth is built.
