In my previous post, I asked a simple question: if London has a housing shortage, why are developers marketing new homes overseas particularly in Singapore?
 
The answer is not just “because foreign buyers are wealthy.”
 
The deeper answer is that the UK housing system has quietly evolved into a model where housing is built locally, but increasingly financed and priced through global capital dynamics.
 
To understand why, we need to look at how the development business actually works.
 
 
Developers Don’t Build Homes — They Build Financial Models
 
Most people assume property developers are mainly in the business of building housing.
 
But in reality, major developers are equally in the business of managing risk and securing funding.
 
Large developments cost hundreds of millions to deliver. They require:
 
 
Before a project is even fully built, the developer needs to prove that the units will sell.
 
And this is where overseas buyers become strategically useful.
 
 
Why Overseas Buyers Are So Valuable
 
Developers love overseas buyers for one simple reason:
 
they buy early.
 
Many international investors are willing to purchase off-plan sometimes years before completion. UK owner-occupiers often wait until buildings are close to finished, and they tend to be more price sensitive.
 
Early off-plan sales allow developers to:
 
 
In other words, selling overseas isn’t just marketing.
 
It’s part of the funding mechanism.
 
 
The “Sold Out” Illusion
 
Another benefit of overseas selling is psychological.
 
Once a development is “70% sold,” it creates an impression of scarcity and success. That helps developers raise prices in later phases and gives hesitant buyers confidence that they are buying into a winning project.
 
But “sold” does not always mean “occupied.”
 
In some cases, the buyer base is heavily investor-driven, which can later create problems in the resale and rental market if too many similar units come onto the market at the same time.
 
This is one reason why some London new-build developments feel plentiful on resale even when the government claims London is short of housing.
 
 
The UK Housing Crisis: Shortage or Misalignment?
 
This leads to a major misunderstanding in the public conversation.
 
The UK absolutely has a housing crisis.
 
But the crisis is not simply “we don’t have enough homes.”
 
The crisis is that we don’t have enough homes priced in line with domestic incomes.
 
So we end up with a strange reality where:
 
 
That isn’t a contradiction.
 
It’s a misalignment.

 
The Political Narrative vs the Market Reality
 
Politicians regularly call for more housing, especially in London.
 
But the UK system relies heavily on private developers to deliver it and private developers can only deliver if the numbers work.
 
The numbers are shaped by:
 
 
If developers were forced to sell everything at genuinely affordable prices, many projects would simply not be built at all.
 
So the system quietly depends on a portion of units being sold at premium pricing often to global buyers to subsidise the overall scheme.
 
That is why overseas marketing continues, even while affordability becomes a bigger political theme.
 
 
Should the UK Restrict Overseas Selling?
 
This is where things become politically sensitive.
 
Some argue that London housing should prioritise local buyers and restrict international marketing.
 
In theory, it sounds reasonable.
 
But in practice, it creates a difficult trade-off.
 
If overseas sales are restricted without solving the underlying economics, developers may:
 
 
So the question becomes:
 
Do we want to restrict overseas buyers, or do we want to redesign the funding model of housing delivery?
 
Because overseas buyers are not the cause of the affordability crisis.
 
They are one of the mechanisms keeping development viable under current conditions.
 
 
 
The Hard Truth: Housing Is Treated as a Social Need and a Global Asset at the Same Time
 
This is the heart of the UK housing contradiction.
 
Housing is spoken about politically as a domestic necessity.
 
But in practice, London housing is increasingly priced like a global financial product.
 
So the market becomes split:
 
 
That is why London can be “short of housing” and still need to be marketed in Singapore.
 
The shortage is not of units.
 
It is of affordability.
 
 
Conclusion: Overseas Marketing Isn’t the Problem — It’s the Symptom
 
It’s easy to look at London developers selling in Singapore and assume it is simply greed or opportunism.
 
But the reality is more structural.
 
London development is expensive, and domestic affordability is stretched. Overseas buyers provide early sales and financial stability that keeps projects moving.
 
So the overseas roadshows aren’t necessarily proof that London is booming.
 
They may be proof that London housing has become increasingly dependent on global liquidity to function.
 
And that should lead to the bigger question:
 

 

If the UK wants housing to serve domestic needs, should it continue relying on a development system that requires global capital to make it viable?
