It's in the middle of the article:

> Another economic factor in the falling birthrate is the rising price of real estate and a resulting increase in unmarried or late-marrying people. The tradition in Korea is for men to prepare a family home before marrying, and the rising cost of housing in recent years has thereby triggered a decline in marriage rates. The Bank of Korea recently enacted emergency interest rate hikes that brought down the price of condominiums, but the interest rate on mortgages has risen, keeping home ownership a distant dream for many.

Ok, there's a bit of a mention there, but they don't seem to consider it the foundational issue. They mention education costs for several paragraphs - education costs would likely not be so high if real estate costs weren't so high.

Fewer desireable/high paying jobs gets several paragraphs, but again, this would be less of a problem if rents weren't so high - people would be able to live on the incomes available. High real estate prices are sucking the oxygen out of the rest of the economy.
