Seoul raised the maximum floor area ratio for apartments in semi-industrial zones from 250% to 400%. A 10% factory share and a 3,000 square meter site threshold decide the procedure — and applied to the Changdong 608 site, the unit count swings by more than 600 homes.
The jonghapbudongsansae exclusion filing window runs just 15 days, from September 16 to 30. Missing two qualifying rental units can push the bill from 300,000 won to 4.2 million on 2 billion won of assessed value.
Korea's first-home acquisition tax relief caps at 2 million won for homes priced up to 1.2 billion won. Because the cap is a flat amount, it erases 67% of the tax on a 300 million won home but only 5.6% on a 1.2 billion won one.
Earn ₩55 million or less and you get 17% of your rent back; earn more and it drops to 15%. On ₩600,000 monthly rent that is ₩1,224,000 versus ₩1,080,000 — a ₩144,000 swing on one won of salary.

The newborn special didimdol mortgage runs from 2.05% (household income under 20 million won) to 4.50% (dual-income up to 200 million) on a 30-year term. Stack every rate discount and the final rate still stops at 1.2%.
Korea's second housing property tax instalment is due 16-30 September. A single-home owner with a 500 million won assessed value pays 620,000 won a year, half of it now. The urban planning surcharge often exceeds the base tax itself.
A housing lease must be reported within 30 days of signing if the deposit exceeds 60 million won or monthly rent exceeds 300,000 won. With the grace period ending 31 May 2025, contracts signed from 1 June carry fines of 20,000 to 300,000 won.
As of March 2026, a 70-year-old with a 300 million won home draws 923,000 won monthly. The same home pays 758,000 at 65 and 1,449,000 at 80 — and the break-even age for waiting is calculable.
The jangki suseon chungdanggeum (long-term repair reserve) is legally the owner's cost, so tenants reclaim it on move-out. Applying the statutory formula, a 110 sq m unit runs 16,000-49,000 won a month, or 390,000-1,180,000 won over two years.
