The latest monthly figures from the state-owned SBAB and the housing website Booli show a weak decline overall for the housing market, minus 0.1 percent.
Adjusted for seasonal effects, however, prices rose by 0.7 percent, and since the turn of the year, the increase is 7.3 percent.
"Looking at the development of housing prices over a longer period, one sees a clear average negative seasonal effect in September. However, in recent years, we see that the negative effect has decreased for apartments and is now non-existent," says SBAB's chief economist Robert Boije in a press release.
Among apartments, a simultaneous increase of 1.7 percent is seen, with price increases in four out of six regions. The largest increase is noted in the metropolitan regions of Gothenburg and Stockholm, and since the turn of the year, prices have risen by 9.3 percent.
This is happening at the same time as villa prices, on the other hand, are falling. The largest decline is seen regionally in southern and northern Sweden.
"It remains to be seen what a likely relatively large pent-up demand for changing housing means for housing prices during the last months of the year, compared to the historically large supply and normally negative seasonal effects," says Robert Boije.
