Investing in property involves dealing with developers and agents who can start throwing around percentages, assuming you know what they mean. With every property, marketing materials will give you a yield figure. However, do you know what it actually means and whether it’s a good one? If you’re a beginner investor considering a potential property purchase, understanding gross rental yield is important so that you can make an informed decision.

Below, we’ll delve deeper into what is meant by gross rental yield, how to calculate it and how to compare the yield and potential of 2 potential properties you are looking at buying.
1. What is meant by “gross rental yield”?
Gross rental yield means the percentage return you earn from rental income before deducting property-related expenses, which are relative to the property purchase price. It is the most commonly used metric in buy-to-let property, and this is important. It provides a quick, realistic snapshot of your property’s income and its anticipated performance.
According to the Global Property Guide (2025–2026), “The average gross rental yield in South Africa stands at 10.93% (Q4, 2025).”(Source)
In simplified terms, “yield” lets you know: How hard is your property working for you?
2. How do you calculate gross rental yield?
Understanding how to calculate gross rental yield is laid out below:
Annual Rental Income ÷ Purchase price × 100 = Gross Rental Yield
For example, if you bought an IGrow 2-bedroom, 1-bathroom unit in Green Leaf estate in Brakpan, Johannesburg:
- Property purchase price: R664,4000
- Monthly rental income: R6,800
- Annual rental income: R81,600
Calculation:
(81,600 ÷ 664,4000) X 100 = 12% gross rental yield. This is a good yield.
That is how you do the calculation; there are no complicated formulas or any financial jargon involved.
Understanding how to calculate gross rental yield means you can compare properties instantly, without needing to sift through complex spreadsheets.
3. What is the difference between gross and net rental yield?
At this point, many investors can get confused.
When you compare gross vs net rental yield, the main difference is what you get out of your investment.
- Your gross rental yield figure does not include costs.
- Net rental yield deducts expenses.
Net rental yield includes expenses like:
- Monthly levies
- Municipal rates and taxes
- Property maintenance
- Rental management fees
The gross rental yieldis your starting point, while your net yield gives you a clearer picture of actual cash flow. Understanding the difference between gross vs net rental yield is important. IGrow properties always have net yields clearly indicated, with each expense listed and conservative prediction figures, such as annual rental escalations, shown in the Financial Analysis on each investment property’s landing page.
4. What is considered a “good” gross rental yield in South Africa in 2026?
According to the Global Property Guide 2025/2026 rental yield reports:
- South Africa’s Gross rental yield national average: ±10.93%
- Johannesburg’s gross rental yield: ±13.69% (shows higher yields due to lower property purchase prices in relation to rent)
- Cape Town: ±8.98% (lower yields due to higher property purchase points)(Source)
In general, the following makes sense:
- Above 10% gross rental yield = is perceived as strong in the South African property market
- 8–10% = Solid, specifically in high-demand nodes
- Below 8% = Necessitates strong capital growth potential to justify your property purchase
However, you should always view yield in relation to factors such as tenant demand, infrastructure growth, and long-term capital growth (appreciation), which are all important to consider. So Cape Town typically offers lower gross rental yields but higher capital growth (increase in property prices).
5. Why does IGrow consider gross rental yield?
At IGrow, we look at gross rental yields as a valid way for people to compare with other investments on the market, as it’s an industry standard. In our assessment of a property’s value, we actually look more closely at the annualized return on investment to make sure it is a good investment. When strategists discuss specific units for an investor’s property investment proposal, and in our Financial Analyses (available on all our property landing pages) we always give the NET yield for a clearer picture of what people will actually get out of their investment.
Gross rental yield is seen as your filter, so when you look at different properties accross the market, you can compare apples with apples.
6. How do you compare two properties using gross rental yield?
In this case, property investment yield comparison becomes a powerful tool.
See the example below- a comparison of the yield of 2 properties with different purchase prices and rental outputs.
Property A: An IGrow 2-Bedroom, 1-bathroom apartment in Southgate Ridge, in Meredale, Johannesburg South
- Price:R769,900
- Annual rent: R82,500
- Yield: 11%
Property B: An IGrow 3-bedroom, 2-bathroom, duplex in Eagle View, in Kempton Park, Johannesburg
- Price: R1,695,000
- Annual rent: R156,000
- Yield: 9%
Although Property B earns more rent, Property A offers you a higher return relative to the capital invested. The yield is 11% at Property A. These properties are both good investments. While Property A presents a lower outset cost, Property B is bigger in size, and produces a sizable monthly rental income. Property B has a 9% yield. Remember, there are always other pros and cons, other than just considering yield comparisons, such as eligibility for Section 13 (sex) taxable income deductions, or how long a property will take to become cash flow positive.
Using a property investment yield comparison means investors can avoid being overly impressed by high rent figures without factoring in the property’s purchase price and the cost of financing it.

7. What are the common yield traps?
Not every high-yield property equals a good investment.
High yield occurring in a low-demand suburb
A potential property may show a 14–15% yield, but if vacancy rates are high or the area lacks economic/infrastructural growth, your rental income can be unstable.
Lower yield in a sought-after, high-demand suburb
An 8–9% yield in a strong-demand, well-situated area may offer optimal tenant stability, a lower vacancy rate, and long-term capital growth potential.
Smart investors balance yield with demand-related credentials, factoring in popular suburbs, potential vacancy rates, infrastructure growth, and access to amenities and essentials, such as schools, tertiary institutions, medical facilities, and shopping centres.
