Refinance $1 Million, You Keep $1 Million. Sell for $1 Million Profit, You Keep $800K. Here Is Why.

A client rang me last week to say his property had appreciated by $1 million since purchase. He wanted to sell and "lock in the profit." I told him he was about to give away $200,000 for no reason. He did not believe me until I showed him the numbers on a whiteboard.

The maths is painfully simple. When you sell a property for a $1 million profit, you do not keep $1 million. You pay capital gains tax. You pay agent's commission. You pay conveyancing fees. You pay marketing costs. What started as $1 million in profit ends up as roughly $780,000 to $820,000 in your pocket.

When you refinance and extract $1 million in equity, you keep $1 million. It is not taxable income. There are no agent's fees. No marketing costs. No capital gains tax. The money is yours to deploy — into the next investment, into renovations, into whatever builds more wealth.

This is one of the most powerful wealth-building concepts in Australian property investment, and it is the one most investors discover too late. After more than 350 transactions at Optima Real Estate, I can tell you that the wealthiest property investors I know almost never sell. They refinance, extract equity, and buy again 1.

The $200,000 whiteboard calculation

Let me walk you through the exact numbers I showed my client.

Scenario A: Sell the property

Purchase price: $700,000 Current value: $1,700,000 Capital gain: $1,000,000

Costs of selling:

• Agent's commission (2% of sale price): $34,000
• Marketing and advertising: $8,000
• Conveyancing and legal fees: $2,500
• Mortgage discharge fee: $350
• Total selling costs: $44,850

Capital gains tax (held more than 12 months, 50% discount):

• Taxable capital gain: $1,000,000 x 50% = $500,000
• Added to taxable income at 45% marginal rate (above $180K): $225,000
• Less Medicare levy (2%): approximately $10,000
• Total CGT: approximately $235,000

Net proceeds from selling: $1,000,000 - $44,850 - $235,000 = $720,150 2

The client keeps $720,150 out of a $1,000,000 profit. Roughly 72 cents on the dollar.

Scenario B: Refinance the property

Current value: $1,700,000 Current loan balance: $560,000 (original 80% LVR on $700K) Available equity at 80% LVR: ($1,700,000 x 80%) - $560,000 = $800,000

Costs of refinancing:

• Bank valuation fee: $300
• Application or switching fee: $500
• Legal/discharge fees if switching lenders: $1,000
• Total refinancing costs: approximately $1,800

The client extracts $800,000 in equity. Tax-free. Total cost: $1,800.

Net equity extracted: $798,200 3

By refinancing instead of selling, the client keeps $798,200 versus $720,150. That is $78,050 more in accessible capital. But that is not the full picture.

The compounding advantage (why the gap is actually much larger)

The $78,000 difference in the immediate calculation understates the true advantage of refinancing. Here is why.

When you sell, you lose the asset. The $1.7 million property that was growing at 5 to 8 per cent per year is gone. You have $720,000 in cash. If you reinvest that into a new property, you are starting over — new stamp duty ($80,000+), new legal fees, new search costs, and a new asset that needs time to appreciate.

When you refinance, you keep the asset. The $1.7 million property continues to appreciate. At 6 per cent annual growth, it adds $102,000 in value in the next year alone. Plus it continues generating rent. Plus you have $800,000 in extracted equity to deploy into additional properties.

Let me model this over five years.

Sell and reinvest: You take $720,000, buy a new property for $900,000 (with additional savings for the deposit shortfall), pay $44,000 in stamp duty. After five years at 6% growth, the new property is worth $1,204,000. Total position: $1,204,000 minus $720,000 loan = $484,000 equity.

Refinance and hold: Original property continues at 6% growth: $1,700,000 becomes $2,275,000 after five years. You use $200,000 of the extracted equity as deposits on two additional $650,000 properties. After five years at 6% growth, each is worth $870,000. Total portfolio value: $2,275,000 + $870,000 + $870,000 = $4,015,000. Total loans: $560,000 + $800,000 (refinanced) + $520,000 + $520,000 = $2,400,000. Total equity: $1,615,000 4.

The sell-and-reinvest path produces $484,000 in equity after five years. The refinance-and-hold path produces $1,615,000.

That is not a 10 per cent difference. That is a 3.3x difference. And the gap only widens over time because compounding accelerates as the portfolio grows.

When refinancing works (and when it does not)

I am not suggesting that refinancing is always superior to selling. There are situations where selling is the right strategy. But they are fewer than most people think.

Refinancing works when:

• The property is generating positive or neutral cash flow. The rental income covers the increased loan balance after refinancing.
• You have a clear plan for the extracted equity — a specific acquisition target or renovation project.
• Interest rates are manageable. The cost of servicing the increased debt does not exceed the return from the assets the equity funds.
• You have borrowing capacity. The bank will approve the refinance based on your income, existing debts, and the property's valuation.

Selling makes sense when:

• The property is structurally declining — high maintenance costs, poor location fundamentals, or an area entering long-term decline.
• You need to restructure your portfolio — exit a low-performing asset to reinvest in a higher-performing one.
• You have reached a life stage where reducing debt is more important than building assets (approaching retirement, for example).
• The CGT liability is minimal — early in the hold period, or when you have substantial capital losses to offset against the gain.

The critical mistake is selling a performing asset purely to access the profit. That is like cutting down an apple tree because you want the apples. The tree keeps producing apples. The stump does not 5.

At Optima, we run a refinance-first strategy for every client whose property has appreciated significantly. We engage the bank for a new valuation, assess the extractable equity, model the debt serviceability impact, and then identify acquisition targets for the released equity. The entire process takes four to six weeks, costs less than $2,000, and unlocks hundreds of thousands of dollars in growth capital.

Our granny flat strategy is specifically designed to accelerate this cycle. A $110,000 granny flat addition typically increases the bank valuation by $120,000 to $150,000. That manufactured equity, combined with organic capital growth, can produce a refinanceable amount within 12 to 18 months of the original purchase — allowing the client to buy their next property without saving an additional dollar of cash 6.

The psychology of selling (why people still do it)

If the maths so clearly favours refinancing, why do people sell?

Because selling feels like winning. When you sell a property for $1.7 million that you bought for $700,000, you get a big number in your bank account. It feels tangible. It feels real. You can show your partner the bank statement and say "we made a million dollars."

Refinancing does not feel like winning. You get a bigger mortgage. Your debt goes up. The equity is redeployed into another property that you cannot touch or spend. The wealth is real, but it is abstract — it exists on paper, in valuations, in future potential.

I deal with this psychology every week. Clients who have watched their property appreciate by $200,000 or $300,000 feel an overwhelming urge to "lock it in." To sell. To convert the paper gain into real money.

But paper gains ARE real money. A bank valuation of $1.7 million means any bank in Australia will lend against that value. You can extract 80 per cent of it as cash. The wealth is not hypothetical — it is lendable, deployable, and compounding.

The investors who build serious multi-property portfolios — the ones who retire with $5 million in assets and $8,000 per month in passive rental income — are the ones who resist the urge to sell. They refinance. They buy again. They let compounding do the heavy lifting 7.

I have one client who started with a single property in Melbourne's southeast purchased for $600,000 four years ago. Through a cycle of renovate, refinance, and reinvest, she now controls three properties worth a combined $2.4 million. She has never sold a property. She has never realised a capital gain. She has never paid a dollar of CGT. And her net equity position has grown from $120,000 to over $700,000 8.

That is the power of refinancing. Not the $78,000 difference in the immediate calculation. The millions of dollars in long-term portfolio growth that selling would have destroyed.

How to refinance properly (the practical steps)

If you are sitting on a property that has appreciated significantly and you want to extract equity, here is the process.

Step 1: Get a professional valuation. Your bank will order a valuation through their panel. Cost: $300 to $500. Some banks offer free desktop valuations for existing customers. The valuation determines how much equity is available.

Step 2: Calculate your extractable equity. Most banks lend up to 80 per cent of the property's current value without requiring Lenders Mortgage Insurance (LMI). If your property is valued at $1 million and your current loan is $500,000, your extractable equity at 80% LVR is ($1,000,000 x 80%) - $500,000 = $300,000.

Step 3: Check your serviceability. The bank will assess whether you can service the increased loan. This is based on your income (including rental income from existing properties), existing debts, and the bank's assessment rate (currently around 7.5 to 8 per cent). If your serviceability is tight, consider a broker who can find a lender with more flexible assessment criteria.

Step 4: Determine the purpose of the funds. If the extracted equity will be used to purchase another investment property, the interest on the equity release is tax-deductible. This is critical. The deductibility of the interest depends on the purpose of the borrowing, not the security. Document the purpose clearly 9.

Step 5: Deploy the equity. Use the extracted funds as the deposit on your next acquisition. At 10 per cent deposit, $300,000 in equity controls $3 million in additional property. At 20 per cent deposit, it controls $1.5 million.

The entire process takes four to six weeks. Total cost: less than $2,000. No agent's commission. No marketing costs. No CGT. No stamp duty on the existing property (only on the new acquisition).

Refinance $1 million, you keep $1 million. Sell for $1 million profit, you keep $800,000. The numbers speak for themselves.
