1. The Short Answer
"Rent is dead money" is only half true. A large part of a bond payment in the early years is also dead money: it goes to interest. In our model, renting and investing the difference comes out ahead for about the first 5 to 10 years. Over 20 years, buying usually wins, unless house prices grow very slowly.
Three things decide it: how long you stay, how fast your home's value grows, and whether a renter actually invests the difference every month. Without that last step, buying nearly always wins, because a bond forces you to save.
2. Upfront: What Buying Costs on Day One
For a R1,500,000 home with a 10% deposit, using the same estimates as our bond calculator:
| Item | Amount |
|---|---|
| Deposit (10%) | R150,000 |
| Transfer duty (3% above R1,210,000) | R8,700 |
| Transfer attorney fees (estimate) | R19,500 |
| Bond registration fees (estimate) | R17,000 |
| Deeds office fee (estimate) | R2,720 |
| Bank initiation fee (up to) | R6,038 |
| Total cash needed | about R204,000 |
About R54,000 of that is pure cost, which you do not get back. A renter normally pays only a deposit of a month or two's rent, which is refundable. Our home buyer's guide explains each of these costs.
3. Monthly: Owner vs Renter
Assuming a R1,350,000 bond over 20 years at 10.75%, and a similar home renting for R11,000 a month:
| In year one, per month | Owner | Renter |
|---|---|---|
| Bond instalment | R13,706 | |
| Rates, levies, insurance and maintenance | R4,000 | |
| Rent | R11,000 | |
| Total | R17,706 | R11,000 |
Owning costs R6,706 more a month at the start. In the first month, about R12,094 of the bond instalment is interest, and only about R1,612 repays capital. The gap narrows over time, as rent and running costs rise while the bond instalment stays flat if rates do not change.
4. Results After 5, 10 and 20 Years
Our model compares what each person has after selling or cashing out:
- Owner: home value, less 6% selling costs, less the bond balance.
- Renter: invests the R204,000 upfront cash, then each month's cost difference, at an assumed 8.5% a year after tax and fees.
Rent and owner running costs rise 6% a year. The bond rate stays at 10.75%. Taxes on selling a primary home are ignored, since the first R3 million of gain is excluded.
| Home value growth | After 5 years | After 10 years | After 20 years |
|---|---|---|---|
| Renter (all cases) | R750,050 | R1,387,341 | R2,829,440 |
| Owner, 3% a year | R411,898 | R889,661 | R2,546,617 |
| Owner, 4% a year | R492,802 | R1,081,884 | R3,089,484 |
| Owner, 5% a year | R576,878 | R1,291,481 | R3,741,150 |
| Owner, 6% a year | R664,219 | R1,519,835 | R4,522,061 |
What this shows:
- At 5 years, renting wins in every case. Upfront and selling costs take years to recover.
- At 10 years, it is close. Buying only wins at about 6% growth.
- At 20 years, buying wins from about 4% growth, because the bond is paid off and housing costs stop rising as fast as rent.
These are model outputs, not predictions. Nobody knows future house prices, interest rates or investment returns.
5. The Assumptions That Change the Answer
- Rent relative to price. Here annual rent is 8.8% of the home's price. Where rents are low compared with prices, renting looks better. Where rents are high, buying does. Our rental yield calculator includes a buy-versus-rent check.
- Interest rates. Your rate rises and falls with prime; see our fixed vs variable guide.
- Extra bond payments. Paying more into the bond improves the owner's result.
- Investment return and discipline. The renter's result depends on investing R6,706 a month without fail. Using a TFSA or retirement annuity can improve after-tax returns, within the limits.
- Levies and maintenance. Older homes and complexes with special levies cost more. Budget properly for geysers, roofs and security.
- Location. National averages say little about your suburb. Check actual sale prices for your street, rather than asking prices.
6. What the Numbers Leave Out
| Buying gives you | Renting gives you |
|---|---|
| Stability and control: no landlord, renovate as you like | Flexibility: easy to move for work or family |
| Forced saving through the bond | No surprise repairs |
| A paid-off home in retirement, lowering costs | Diversified investments, not one asset in one suburb |
| Exposure to one property and municipal service problems | Rent increases and the risk of a lease not being renewed |
7. Test Your Own Numbers
- Find a real comparison: a home you would buy, and what a similar one rents for.
- Work out the upfront cash and monthly cost in the bond calculator.
- Be honest about how long you will stay. If it is under about five years, renting usually wins.
- Ask if you would really invest the difference. Set up a debit order before deciding on that basis.
- Check that you are not stretching. Test the instalment at two points above today's rate. Do not spend your whole emergency fund on the deposit.

Open Bond Calculator →Frequently Asked Questions
Is it better to rent or buy in South Africa?
It depends on how long you stay, how much the home's value grows and whether you invest the savings. In our model, renting and investing wins over about 5 years, 10 years is close, and buying usually wins over 20 years.
How much cash do I need to buy a R1.5 million home?
About R204,000 with a 10% deposit: R150,000 deposit plus about R54,000 in transfer duty, attorney, deeds and bank fees. Attorney fees are estimates.
Is rent dead money?
Only partly. In the first years of a bond, most of each instalment is also interest. In our example, about R12,094 of a R13,706 first instalment goes to interest.
How long should I stay to make buying worthwhile?
In our model, buying does not catch up by year 5 at any growth rate tested, and only passes renting by year 10 at about 6% growth. Your own numbers may differ.
Do I pay capital gains tax when I sell my home?
Usually not on an ordinary home. The first R3 million of gain on a primary residence is excluded from 1 March 2026.
