Non-financial assets of Korean households make up more than 70 percent of all assets-- and most of them are tied up in real estate.
Statistics Korea data shows that real estate assets, in particular, accounted for around 68 percent of households' non-financial assets last year.
That is down almost 2 percentage points from a year earlier.
Experts say unlike in the past when property prices continued rising, real estate may no longer be a profitable investment outlet.
They caution that an asset structure that leans too heavily on property could have a devastating impact on household finances should prices go down.
They suggest people sell some of their real estate to enhance financial liquidity for a stable source of income for the years after retirement.
