Seoul's Rally Moves North: Seongbuk Leads at 1.73% While Gangnam Buyers Sit Out

Seoul home sales prices rose 1.09% in July from a month earlier, 0.06 percentage point wider than June's 1.03%, according to the Korea Real Estate Board's nationwide housing price survey ^[1][2]. That happened while buyers in the affluent Gangnam area held back and demand moved instead to northern districts and the city's outer edges ^[8], which is the part that matters: a market that is cooling at the top and accelerating in aggregate is not cooling, it is rotating.

The dispersion is the story. Seongbuk District rose 1.73%, the steepest of the city's 25 districts ^[5], about 1.6 times the citywide figure ^[1]. Nowon followed at 1.64%, then Jungnang at 1.35%, Seodaemun at 1.26% and Jung at 1.23% ^[6]. The REB places the Seongbuk gains around major complexes in Hawolgok and Gireum, and the Nowon gains in Sanggye and Junggye, areas it describes as having redevelopment potential ^[7]. This is not a story about scarce prime stock. It is a story about optioned-up cheap stock.

South of the river, the same filter applies. Within the Gangnam area, it was the lower-priced districts and those with redevelopment expectations that moved: Guro up 1.33% around the Gaebong and Guro station neighbourhoods, Gangdong 1.29%, Yeongdeungpo 1.27%, Songpa 1.15% around Geoyeo and Jamsil, and Gangseo 1.03% around Deungchon and Yeomchang ^[9]. The gap between the fastest district and Gangseo at the bottom of that list is 0.70 percentage point in a single month ^[4]. An REB official said "a wait-and-see mood is spreading across Seoul, but transactions at higher prices have continued in areas with redevelopment expectations and complexes with good living conditions" ^[10]. The board added that buyers feel the strain of prices, particularly for higher-priced homes, while sales at rising prices continue where demand is steady, near subway stations or in large complexes ^[11].

Scale it up and the numbers get harder to read as a soft patch. Seoul is up a cumulative 5.66% through July, about 1.8 times the 3.11% of the same period last year ^[4], a simple annualised pace near 9.7% ^[3]. The citywide monthly rate is roughly three times the national 0.35%, and well above greater Seoul's 0.72% ^[3][2]. Apartments alone rose 1.27% in July, widening from 1.21%, for a cumulative 6.40% versus 4.54% a year earlier ^[12]. Greater Seoul apartments also widened, from 0.81% to 0.88% ^[13].

The rental side is where the pressure shows. Seoul jeonse rose 1.03% in July, easing from 1.08% ^[14], and apartment jeonse rose 1.28%, down from 1.37% ^[16]. But cumulative apartment jeonse of 6.34% now nearly matches sales at 6.40%, against 1.24% and 4.54% respectively last year ^[16] - roughly five times last year's jeonse pace ^[6]. Monthly rents rose 0.94%, with apartments at 1.12% against 0.73% for low-rise multi-unit and 0.51% for detached ^[17]. Nowon led rents at 1.67% and Seongbuk at 1.60% ^[18], the same two districts leading sales. Citywide monthly rents are up 4.79% year to date versus 1.13% a year earlier, about four times the pace ^[19][5].

Watch the divergence in the August print: sales widened by 0.06 point in July while overall jeonse narrowed 0.05 and apartment jeonse narrowed 0.09 ^[7]. If rents keep decelerating while sales keep widening in Seongbuk and Nowon, the northern bid is being priced on redevelopment expectation rather than occupier demand, and it will be sensitive to anything that changes the permitting arithmetic.
