When a cheaper rent makes an apartment harder to find
A rent cap can make an individual apartment affordable, but it cannot make more apartments available. When regulated rents sit below what many people would pay for a home in a sought-after part of Stockholm, demand exceeds the supply of those homes. The shortage then shows up not only in price, but in time: applicants compete for access through a queue, and a place near the front can become valuable in its own right.
The queue rewards staying put
A long wait can turn a regulated lease into something like a scarce asset. People who already hold one may have little reason to give it up, especially if moving means losing a favorable rent and starting over elsewhere. That slows the circulation of apartments: even when a home becomes vacant, the next person may have waited years to get it.
The system’s benefit and its bottleneck are linked. Tenants who secure regulated homes can gain predictable, comparatively affordable housing. But newcomers, people who need to move quickly, and those without a long queue history face a much narrower set of options.
Why illegal sublets can command more
When someone needs a place now, waiting is not a practical substitute for housing. They may turn to a sublet from a leaseholder instead. If the rent charged is not permitted under the rules, the arrangement is illegal; yet scarcity can make tenants willing to pay more for immediate access than the regulated system would allow for the original lease.
That creates a sharp divide: the official route allocates a scarce home through time, while the unofficial route can allocate it through money. The longer the queue stretches, the more a leaseholder’s ability to offer temporary access can matter—not because the apartment has changed, but because so few alternatives are available.
