No, it is just the messed up rental market in Stockholm. Government and HOA controls don't let people be landlords for more than 2 years of a time and require you to ask permission from the HOA and to have a reason.
The actual apartment I was renting was pretty well kept though, proper cleaning, air ventilation inspections, very good laundry room, fully renovated less than 10 years before I moved in. The apartment I bought however was similar conditions.
It is possible to get a first-hand rental contract but it takes years upon years and you can never get something in the location you want.
