The line between homeowner and landlord is blurring. In an evolving economic landscape, more and more people are turning their homes into short-term rentals, and a new report suggests this trend could be reshaping the very foundation of the housing market.
Between 2020 and 2024, the number of rented-out homes tripled, a staggering surge that has continued into 2025. According to data from Eurostat, popular platforms like Airbnb and Booking.com saw guest nights jump from 2.5 million in 2020 to over 8 million in 2024. For many, this has become an essential way to supplement income. As economist Arturo Arques notes, the desire for an extra source of income is a key driver behind the 25% average increase in rentals over the past two years.
A Risky Strategy
But the story isn’t just about extra cash. Another major factor is the struggling housing market itself. Faced with a poor sales environment, many homeowners who can’t get their asking price are choosing to rent their properties instead of selling at a loss. It’s a calculated gamble, a bet that they can wait out the downturn and secure a better price later.
This strategy, however, has a downside. Arques warns that this shift could be turning residential properties into speculative assets. A home, traditionally a place of stability, is becoming an investment vehicle. And as any economist will tell you, a market built on speculation is a volatile one, prone to “high peaks” and “deep troughs.”
The Domino Effect
The danger lies in what happens when the market inevitably turns. When many people feel that their homes are no longer a stable asset but a risky investment, they will want to reduce that risk. The most common way to do that is to sell. This could trigger a domino effect: a sudden influx of properties on the market, potentially leading to a sharp drop in prices and creating a more unstable, uncertain market for everyone.
This trend is a stark reminder of the interconnected nature of the housing market. What begins as a personal financial strategy for a few could have far-reaching consequences, potentially impacting the value of every home on the block.
Construction Provides a Silver Lining
While the rental market poses new risks, there are signs of positive momentum elsewhere. The Swedish housing construction sector saw a pickup in the first half of 2025. According to the Statistical Central Bureau (SCB), work began on 15,400 new apartments, a 3% increase from the same period in 2024. The biggest boost came from small houses, where new apartment starts rose by 22% compared to last year. This increase in supply could help alleviate some of the pressure on the housing market, potentially providing a more stable foundation amidst the speculative forces at play.
