The housing crisis is not a mystery. It is a sum of errors that we choose not to correct.
There is a tendency in Portugal to treat the housing crisis as if it were an almost inevitable phenomenon, a kind of modern fatality caused by excess demand, foreign investors or interest rates. But that is a convenient simplification. The truth is more uncomfortable. The crisis is not born from a cause. It is born from a system that for years has accumulated blockages, distortions and bad decisions, without the courage to attack the structural causes.
The IMF itself has now reminded us of something that many prefer to ignore: the housing crisis is no longer just a social problem. It is an economic problem. It affects productivity, drives talent away from urban centers, and slows down growth. Young people who cannot live close to the centers where they work are an economic problem. Companies that cannot attract people because the cost of housing is unaffordable are an economic problem. And a country where prices rise almost 19% in a year, while incomes do not follow, has a structural problem.
But it is not enough to repeat that there is a lack of supply.
It is necessary to ask why.
Why is so little built? Why does approving a project take years when it should take months? Why is funding for promotion still limited? Why is urbanizable land still so constrained? Why do we still depend too much on the will or inertia of local authorities, often without technical means, without vision and sometimes tied to vested interests?
Every minute a project waits costs money.
Interest.Human resources. Construction costs. Missed opportunities.
And these costs end up in the final price of the house.
This is not theory. It's mathematics.
At the same time, we remain stuck in an almost exclusively purchase-oriented model, as if the housing market was limited to selling houses. It is not summed up.
The most mature countries have realized for decades that a true rental economy is necessary. Not a patch. An industry.
Germany.Denmark.Sweden.
All of them have created tax and legal frameworks that make investment in renting attractive, stable and professionalized.
We did the opposite.
We created mistrust. Instability.Risk.
And then we are surprised that the rental market does not respond.
Another mistake is to ignore solutions that already exist. The industrialization of construction, with modular methods, faster processes and more efficient materials, could be reducing costs and speeding up production today. Instead, it continues to be treated almost as an exception.
Why?
Because we continue to complicate what others have simplified.
And then there is speculation. Sensitive topic.
But let's be honest.
It is not only in large investors.
It is also in the small owner who criticizes the prices but sells for the maximum because he knows that later he will have difficulty buying another house.
It is in a market where everyone complains about the problem, but many participate in it.
This is an uncomfortable truth.
It is also true that the lack of productivity in urbanism is a silent scandal.
Simplex was spoken. But in many municipalities little has changed.
Nor systems. Nor teams. Nor execution culture.
And without execution, reform is just speech.
The case of Gaia shows, in fact, that when more licensing is done, the market responds. It doesn't solve everything, but it answers. That should teach us something.
Perhaps the problem is not just a lack of policy.
Maybe it's a lack of courage to copy what works.
Because solutions exist.
Independent urban coordination agencies. Integrated housing, commerce and industry clusters. Reduction of the weight of PDM as a blocking instrument. Public availability of land. Robust tax benefits for institutional leasing. Professionalization of intermediaries to better serve buyers, sellers, landlords and tenants. Industrialized construction models at scale.
None of this is revolutionary.
It's tested.
It works.
But we continue to act as if we had to invent everything from scratch.
We don't.
Just copy better.
And act quickly.
Because every lost year aggravates the problem.
But more than that.
Every minute lost too.
And as long as we continue to treat housing as an ideological debate and not as a problem of economic execution, we will continue to discuss symptoms while the structure remains broken.
The housing crisis is not a mystery.
It is a sum of mistakes that we already know.
And therefore, it should also be a sum of solutions that we should have already applied.
