On 23 September, police carried an 87 year old woman out of her Madrid flat on a stretcher. María del Carmen Abascal had lived in that apartment since 1957. Sixty Nine Years. An investment fund called Urbagestion bought the property and raised her rent from €500 to €2,650 per month, and later trimmed this to €1,650. Her pension was only €1,350.
Tens of thousands marched. Organisers claimed 300,000. The country erupted.
Everyone agreed on the villain. Everyone agreed on the fix. More protection. Tighter caps. Harder limits on landlords.
Everyone drew the wrong conclusion.
The experiment nobody can argue with
Here is what makes Spain different. Spain is not a theory. Spain is a live experiment, running in real time, inside one country.
Catalonia has rent controls. Madrid does not.
Watch what happens next. Catalonia is forecast to lose 7.65% of its rental properties in 2026, dropping below 95,000 homes. Meanwhile, Madrid holds steady at 150,000 and keeps its place as the largest rental market in the country. The researchers are blunt about the cause. Catalonia introduced rent controls. Madrid did not. The controls prompted landlords to leave.
Same country. Same currency. Same culture.
Different rules. Different outcomes.
The damage isn’t confined to one region. Long term rental supply across Spain has fallen 44% in seven years. Barcelona is down 74%. Madrid province is down 54%. Nearly 23,000 more homes are leaving the long term market this year alone. The central bank puts the housing shortfall near 700,000 units.
The result for tenants is brutal. An average of 143 people now chase every listing within ten days of it appearing.
I made the theoretical case for all of this in February last year, in Rent Ceilings, Insufficient Roofs. Berlin, Stockholm, San Francisco. The mechanism was always clear. Spain has now turned the theory into evidence.
Maricarmen is a gap story, not a greed story
Now back to the Maricarmen’s stretcher.
The headlines blamed a cruel fund. Look closer. Maricarmen was paying €500. The market was €2,650. That gap did not appear overnight. It grew, quietly, for decades, while her rent sat frozen far below reality.
That gap is the whole story.
When a sitting rent drifts far below market, you do not protect the tenant. You build a pressure cooker. The wider the gap, the greater the incentive to reset it. The greater the incentive to reset it, the harder the eviction when it finally comes. Freezes do not shield people. They load the gun and wait.
This is the part policymakers refuse to see. In the long term, the kindest rent is not the lowest rent. The kindest rent is the one that tracks the market closely enough that it never has to detonate. Small, regular, predictable adjustments keep tenants housed. Long freezes end on a stretcher, as this one did.
The trap waiting for every operator
Here is the lesson for anyone who prices rental property for a living.
When the law caps future increases at inflation, or at 2%, you lose the ability to correct a price after move in. The day the tenant signs is the only day you ever set the rent to the real market. Every year after that, you are locked.
So, what does a rational landlord do? They front load. They price the first day for the next five years, not for today. The new tenant pays the highest, most defensive price in the market, because the landlord knows there is no second chance.
Read that again, because it is the trap. Caps do not remove pricing risk. They take all of it and move it to day one. And they make a day one mistake permanent.
Price too low at move in and you are locked into that loss for the life of the tenancy. Price too high and the unit sits empty while 143 applicants walk past it to somewhere cheaper. There is no middle correction later. There is only the opening number.
This is why the operators who will survive the regulatory wave are not the ones with the toughest lawyers. More than 90% of Spanish landlords own only a handful of properties, and they are the ones walking away. The amateurs exit. The professionals remain. And professionals win on one thing above all. They get the opening number right.
When you can only set the price once, setting it with precision stops being an advantage. It becomes survival.
The uncomfortable conclusion
Spain wanted fewer evictions. It is getting fewer homes. On 2 October, the Spanish Congress rejected two emergency housing decrees outright. Small landlords, watching the rules change yet again, are deciding it is simply not worth the trouble.
The lesson is not that landlords are heartless or that tenants are owed nothing. The lesson is simpler and harder. You cannot legislate a shortage away. You can only decide who absorbs it. Right now, Spain has decided it will be the young, the mobile, and the next person who needs a home.
Rents can be capped. The value of pricing day one correctly cannot.

Postscript.
As this article was being finalised, Maricarmen Abascal died. She was 87.
An agreement had been reached that would have let her return to the home she had lived in for seven decades. It came too late. Her tenants’ union called it an entirely avoidable situation after a harrowing ordeal. Protesters camped in Madrid’s Sol square held a minute of silence. The prime minister, who had failed to pass his housing measures, has since called an early election.
The debate she set off will now run through an election. I hope it lands on more homes and steadier rents, not another freeze that stores up the next avoidable tragedy.
