Seoul Apartments Average 1.6 Billion Won — So Why Is Songpa Falling?

Seoul's Average Apartment Price: 1.6 Billion Won

The average sale price of an apartment in Seoul has crossed 1.6 billion won. Every time this statistic comes out, it feels surreal — but it's real. What's stranger is that this average is rising while Songpa, one of Seoul's most prestigious districts right next to Gangnam, has just seen prices turn negative. How does that happen?

Why Songpa Is Falling

High-end apartments are especially sensitive to interest rates. If you bought a 2-billion-won apartment with maximum leverage, a 1% rate increase adds hundreds of thousands of won to your annual interest bill. With US Treasury yields spiking and domestic rates showing no sign of dropping, there's less urgency to buy expensive property. Buyers wait, sellers gradually cut prices, and prices turn negative.

On top of that, buying into high-end districts comes with extra hurdles — land transaction permit zones, DSR (total debt service ratio) regulations. These barriers keep speculative demand out. When investment buyers step back, transaction volume drops and prices soften.

Why Cheaper Areas Are Rising

Districts like Nowon, Dobong, and Gangbuk — the so-called 'No-Do-Gang' — are moving on different logic. Buyers who can't afford Gangnam are shifting to 'the most affordable options still inside Seoul.' That's the balloon effect.

This isn't entirely a good sign, though. It doesn't mean Gangnam prices are stabilizing — it means pressure from high-priced areas is migrating to cheaper ones. That's exactly why Seoul's average keeps going up.

What to Actually Watch

Looking at Seoul's average apartment price alone creates a false picture. The real story is a two-speed market: high-end areas under pressure, mid-to-low areas rising. Where you look and what price range you focus on completely changes how you read the market. Whenever you see housing price headlines, always check which neighborhood and which price tier they're talking about.
