South Africa is approving more homes for construction, yet buyers are finding fewer properties available to purchase.
Residential units approved for construction increased by 17% in the first five months of 2026 to about 14,600, according to construction analyst Elsie Snyman. Yet the number of residential properties listed for sale fell 12% year on year in July.
The divergence is creating a property market in which demand remains strong while the supply of properties reaching buyers remains constrained.
For buyers, that means fewer choices and greater competition for desirable properties. For sellers, it can mean more leverage. For developers, it raises a more difficult question: if demand is strong and prices are rising, why is new supply taking time to reach the market?
One consequence is emerging among the estate agents competing to sell those homes.
When agents are competing for fewer listings, there is greater pressure to win the mandate, says Cameron Jansen, General Manager at LWP Properties.
“Do you tell the seller what the evidence suggests their property is worth, or do you risk losing the listing to another agent prepared to suggest a higher price?” he asks.
Jansen says something in LWP’s own numbers has caught his attention. Last month, new listings generated only around 33% of all buyer leads, while the majority of enquiries came from older listings, properties that had already had more time for their asking prices to adjust to the market.
He says this does not prove that new listings are being overpriced, but raises an important question: “Are we seeing agents secure listings at optimistic prices, rather than spending enough time counselling sellers on what buyers are actually prepared to pay?”
The general manager says winning the mandate is not the same as doing the seller a service.
A good agent, he says, should not simply be the person who gives the seller the highest valuation.
“They should be the person prepared to have the difficult pricing conversation, support it with evidence, and help the seller position their property where the market will actually respond. In a stock-short market, I think that responsibility becomes even more important,” Jansen says.
The supply problem
The tension becomes more pronounced when demand is measured against where South Africans live and work.
Johannesburg, South Africa’s economic powerhouse, is home to about 10% of the national population and contributes around 15% of national GDP.
Yet over the past five years, it accounted for just 3.8% of all residential building plans passed nationwide, only marginally higher than Nelson Mandela Bay, which is home to about 2% of South Africa’s population and around 2.6% of its economy.
The figures highlight the importance of where new housing is being built, not simply how many homes are approved nationally.
The pressure is showing up in prices.
Snyman says house prices have reached their highest rate of increase dating back to 2011, rising 8.6% in nominal terms against a 3.1% increase in inflation as at March 2026.
The pressure is particularly pronounced in the affordable housing segment, where demand remains strong.
Yet the increase in construction approvals needs to be treated carefully. An approved building plan is not a completed home.
Between approval and completion sit financing costs, land, infrastructure, regulatory processes, construction costs and the developer’s confidence that buyers will still be there when a project reaches the market.
Snyman says the increase in approvals has slowed since the first quarter, with uncertainty and higher interest rates feeding into the development pipeline.
“It is accepted that higher interest rates are likely to dampen the investment mood to some degree, but within the right affordability segment, demand is now so high, that limited supply will continue to put upward pressures on house prices, creating a more favourable environment for new developments.”
That helps explain how South Africa can be approving more homes while buyers simultaneously experience a shortage of properties available to purchase.
Cape Town shows the squeeze
The Western Cape offers a particularly clear example.
Snyman says house prices increased 12.6%, or 9.6% in real terms, while available properties for sale declined by 16.1%.
She says higher interest rates are likely to slow demand and moderate house price growth as affordability comes under pressure. But where supply remains constrained, particularly in high-demand provinces such as the Western Cape, prices could continue to outperform inflation.
“Supply is simply not keeping up with demand,” Snyman says.
In Cape Town, the distinction between a shortage of homes and a shortage of the right homes is becoming increasingly important.
In the August 2026 overview of the Cape Town property market, Edgar Van Dyk, a real estate candidate property practitioner, describes the defining story as not a lack of buyers but an acute shortage of quality stock.
“Well-priced homes are attracting intense competition, resulting in shorter negotiation windows and sellers achieving close to asking price,” Van Dyk says.
That distinction is important for buyers and sellers. The constraint is not simply the number of houses, but the number of houses in the right locations, in acceptable condition and priced within the reach of active buyers.
This is why scarcity does not automatically mean sellers can name their price.
Samuel Seeff, chairman of the Seeff Property Group, says price remains the first filter for many buyers.
“Before a buyer even looks at a photo online, the price tag decides if the property appears in their search results at all. If it is priced right for their budget, it gets a pass. If it is overpriced, most buyers scroll right past,” Seeff says.
But what constitutes value is changing too.
Buyers are increasingly looking beyond square metres and finishes towards the costs and risks attached to owning a home. Seeff says solar panels, backup battery systems and water storage are increasingly attractive as households seek to manage South Africa’s energy and water challenges.
Reliable internet and space for remote work are also becoming part of the calculation.
For buyers, the immediate consequence is greater competition for well-priced, quality stock. A shortage of listings does not, however, make every property worth its asking price.
For sellers, scarcity creates leverage, but an ambitious asking price can still turn a scarce asset into a stale listing.
For developers, the equation is harder. Rising prices and strong demand create an incentive to build, but higher financing costs, uncertainty and the time required to turn approvals into completed homes can slow the response.
The implications extend beyond property.
Where suitable housing is scarce and expensive, households have less room in their budgets for other spending. Workers may also face difficult choices about where they can afford to live relative to where jobs and economic opportunities are concentrated. For now, the market is showing two different signals: more homes are being approved for construction, while fewer properties are available for buyers to choose from.
For South Africa, the challenge is increasingly one of turning construction approvals into actual supply and doing so quickly enough for the market to absorb the demand already there.
