A deep dive into a property investment vs The World Satrix Index Fund
For many of us, property feels tangible, safe, understandable and emotionally satisfying. You can see it. You can touch it. You can rent it out. You can improve it. You can drive past it and say, “That is mine.”
The stock market, on the other hand, often feels abstract. An index fund does not have a front door, a tenant, a view, a garage or a garden. You do not get to repaint it, renovate it, or decide whether the kitchen should be open-plan. It sits in an investment account, moving up and down on a screen, often in ways that feel disconnected from everyday life.
But investing is not about what feels best. It is about what produces the best result for the risk, effort, cost and time involved.
So I wanted to test a simple question:
What would have happened if, on 31 December 2015, you had R1 million to invest and you had to choose between buying a property in Lakeside, Cape Town, or investing that same money into the MSCI World Index?
This is not a theoretical comparison between “property” and “shares” in general. This is a specific, numbers-based comparison between:
A R1 million cash property purchase in Lakeside, Cape Town
versus
A R1 million investment into the MSCI World Index in rand terms
The period runs from 31 December 2015 to 31 December 2025, giving us a clean ten-year investment horizon.
The result is fascinating, because the property does very well. In fact, it does exactly what many Cape Town property investors hope property will do: it grows strongly in value, produces rental income, and ends the period with a very substantial gain.
But even then, the MSCI World Index narrowly comes out ahead.
Let’s unpack the numbers.
The Lakeside property investment
The property example is based on a R1 million cash purchase in Lakeside, Cape Town, at the end of 2015.
The assumptions are as follows:
The property was purchased for cash for R1,000,000.
Transfer costs were R20,000.
There were no renovation costs.
The estimated sale price at the end of 2025 is R3,300,000.
Selling commission is calculated at 4% plus VAT.
Compliance costs are estimated at R15,000.
The property was rented out from 1 January 2016 to 31 December 2025.
The net rental income in 2016 was R41,820 per annum.
Rental increased by 8% per year from 1 January 2017.
The rental figure is treated as net rental income, meaning property-related running costs have already been deducted as well as the personal income tax on the rental.
There is no vacancy.
Capital Gains Tax has been excluded from both investments in this comparison giving us a clean before-tax investment comparison.
The first thing to note is that the property investor did not only invest R1 million. They also had to pay transfer costs of R20,000.
So the true initial cash investment was:
R1,000,000 purchase price + R20,000 transfer costs = R1,020,000 total cash invested
That matters, because when we compare investments properly, we need to compare the actual cash that left the investor’s pocket.
The capital growth of the Lakeside property
The property was bought for R1,000,000 and is estimated to sell for R3,300,000 at the end of 2025.
On the surface, that is a fantastic result.
The gross capital growth is:
R3,300,000 — R1,000,000 = R2,300,000
That means the property increased by 230% in capital value over ten years.
Put differently, the property became 3.3 times more valuable than its original purchase price.
That is an excellent result by almost any measure. It also reflects what many Cape Town property owners have experienced over the past decade, especially in well-positioned suburbs with lifestyle appeal, access to schools, mountain and coastal amenities, and strong rental demand.
But gross capital growth is not the same as net investment return.
When you sell a property, you do not keep the full sale price. You still need to deduct the costs of selling.
In this case, the estimated selling costs are:
Selling commission at 4% of R3,300,000: R132,000
VAT on commission at 15%: R19,800
Compliance costs: R15,000
Total selling and compliance costs:
R132,000 + R19,800 + R15,000 = R166,800
So the net sale proceeds are:
R3,300,000 — R166,800 = R3,133,200
This is the amount the investor would receive before tax, assuming the property sells for R3.3 million and the stated selling costs apply.
So, on a capital-only basis, the property turns the original R1,020,000 cash investment into R3,133,200.
That creates a before-tax capital profit of:
R3,133,200 — R1,020,000 = R2,113,200
The total capital-only return is therefore approximately 207.18%, with an annualised return of about 11.88% per year.
That is strong. Very strong.
But property is not only about capital growth. If it is rented out, it also produces income.
The rental income
The property was rented out from 2016 to 2025.
The first year’s net rental income was R41,820 for 2016. From 2017 onward, the rental increased by 8% per year.
The rental schedule looks like this:
2016: R41,820
2017: R45,166
2018: R48,780
2019: R52,682
2020: R56,897
2021: R61,449
2022: R66,365
2023: R71,674
2024: R77,408
2025: R83,600
Over the ten-year period, the total net rental income comes to approximately:
R605,828
This is a major part of the property return.
It is also one of the reasons property can be so powerful as a long-term investment. The asset can grow in value while also producing income. That income can help cover holding costs, pay down debt if the property is bonded, or simply create an additional cash return for the investor.
In this example, because the property was bought for cash, the rental income is not being used to service a bond. It flows directly into the overall investment return.
When we add the rental income to the net sale proceeds, the total value created by the property becomes:
R3,133,200 net sale proceeds + R605,828 net rental income = R3,739,028
So the property turns a total cash investment of R1,020,000 into R3,739,028 before tax.
The total before-tax profit is:
R3,739,028 — R1,020,000 = R2,719,028
That gives a total return of approximately 266.57% over ten years.
The annualised return is approximately 13.87% per year.
That is an outstanding result.
A property investment that compounds at nearly 14% per year, before tax, over a full decade is a very successful investment.
But now we need to ask the uncomfortable question.
How does it compare to simply investing the money offshore into a broad global equity index?
The MSCI World Index comparison
For the share-market comparison, we use the MSCI World Index in rand terms.
The MSCI World Index is a broad global developed-market equity index. It includes large and mid-sized companies across developed markets, including the United States, Europe, Japan, Australia and other major economies.
For a South African investor, this is important because the return is affected by two things:
First, the performance of global developed-market shares.
Second, the movement of the rand against major global currencies.
That second part matters enormously.
A South African investing in global equities is not only investing in companies like Apple, Microsoft, Nestlé, Toyota and other global businesses. They are also reducing their exposure to the rand.
Over long periods, rand weakness can significantly increase the rand value of offshore investments.
For this comparison, the MSCI World Index return used is 14.43% annualised over ten years, based on the rand benchmark return reflected in the Satrix MSCI World Index Fund information.
Using that annualised return, a R1 million investment into the MSCI World Index would grow to approximately:
R3,849,453
That means the investment would produce a before-tax profit of:
R3,849,453 — R1,000,000 = R2,849,453
The total return is approximately 284.95% over ten years.
The annualised return is 14.43% per year.
So, on the numbers, the MSCI World Index narrowly beats the Lakeside property, even after including the property’s rental income.
The final comparison
Here is the final comparison:
The Lakeside property, looking only at capital growth after selling costs, ends at approximately:
R3,133,200
The Lakeside property, including net rental income, ends at approximately:
R3,739,028
The MSCI World Index investment ends at approximately:
R3,849,453
So the difference is:
R3,849,453 — R3,739,028 = R110,425
That means the MSCI World Index comes out ahead by approximately R110,425 before tax.
That is not a massive difference in the context of a ten-year investment. In fact, it is surprisingly close.
The property did extremely well. It grew from R1 million to R3.3 million in gross value, generated more than R600,000 in net rental income, and produced a total before-tax value of about R3.74 million.
But the MSCI World Index still did slightly better.
The final annualised returns are:
Lakeside property, capital only: 11.88% per year
Lakeside property, including rental: 13.87% per year
MSCI World Index: 14.43% per year
This is where the lesson becomes interesting.
The property was not a bad investment. It was a very good investment. It just was not quite as good as the global index over the same period.
What this tells us about property investing
This comparison does not prove that shares are always better than property.
It also does not prove that property is inferior.
What it shows is more nuanced.
Property can produce excellent returns when the following things are true:
You buy in the right area.
You buy at a reasonable price.
The suburb experiences strong demand.
You hold for long enough.
You control your costs.
You achieve consistent rental growth.
You avoid long vacancies.
You do not overcapitalise on renovations.
You sell well.
In this case, the Lakeside property benefits from several strong assumptions.
There is no vacancy.
There are no renovation costs.
The rental income is net of costs.
The property grows from R1 million to R3.3 million.
The area performs strongly over the decade.
Even with all of that, the MSCI World Index still edges ahead.
That should make property investors pause.
Not because property is bad, but because the benchmark is powerful.
A low-effort, diversified, offshore index investment can be very difficult to beat over the long term.
The hidden advantage of property: leverage
There is one major advantage of property that this comparison does not include: leverage.
This example assumes the property was bought for cash.
But many people do not buy property for cash. They use a bond.
That changes the calculation completely.
