What Moves When Seoul Home Prices Rise

📈Price signals#

Two indicators point the same way

In the Korea Real Estate Board's weekly survey for the fifth week of August (as of August 31), Seoul apartment sale prices rose 0.22% from the week before, and Seoul jeonse prices rose 0.21%. By the private indicator R114, Seoul apartment prices rose 0.55% over August. Nationwide, the monthly rise widened from April through July and then narrowed for the first time in August. The direction is the same, but the pace has started to change, and that is where this map begins.

🏦Lending rules#

Cutting off credit first

Lending is the first tool the government reaches for. In its 2026 Household Debt Management Plan on April 1, 2026, the Financial Services Commission set this year's household loan growth target at 1.5%. That is lower than last year's actual 1.7% and less than half the nominal growth forecast. It cut the share of policy loans from 30% to 20% and, in principle, blocked maturity extensions on mortgages for apartments that multi-home owners hold in the capital region and regulated areas.

LTV from 70% to 40%#

Wider regulated areas push LTV down to 40%

With more regulated areas designated on June 30, the LTV on mortgages in those areas fell from 70% to 40% from July 1. For multi-home owners, the LTV is 0% anywhere in the capital region. Anyone who takes out a credit loan above 100 million won cannot buy a home in a regulated area for one year. First-time buyers and policy mortgages keep eased ratios of 60% to 70%.

Base rate 3.00%#

Rates raise costs apart from the rules

The Bank of Korea's base rate rose two months in a row, to 2.75% on July 16 and 3.00% on August 27. Stage 3 of the stress DSR has been in effect since July 2025, so loan limits are already calculated at a higher assumed rate. With rules cutting the limit and rates raising the interest, the monthly cost of buying the same home grows from two directions.

🔑Rentals#

Jeonse turns into monthly rent

Demand that cannot buy is pushed into the rental market. An analysis of Korea Real Estate Board data in the National Assembly found that in June 2026, monthly rent, including deposit-backed monthly rent, made up 55.4% of Seoul apartment lease contracts. A year earlier, in June, it was 43.5%. For non-apartment housing nationwide, 78.8% is monthly rent. As jeonse loans are also restricted in regulated areas, the path of holding on through jeonse narrows too.

Jeonse prices up 0.21%#

Jeonse prices rise too

In the same week, Seoul apartment jeonse prices rose 0.21%. When jeonse supply shifts to monthly rent, the remaining jeonse becomes scarce. When jeonse deposits rise, the converted monthly rent rises with them. Prices rise in a market where people who cannot afford to buy crowd in.

🏗️Supply#

Fewer homes to move into now, more construction starts

According to the Ministry of Land, Infrastructure and Transport's July housing statistics, Seoul completions (move-ins) from January to July were 20,916 units, down 43.3% from 36,904 in the same period a year earlier. Starts over the same period were 19,507 units, up 44.4%, and permits were 28,634 units, up 6.1%. The gap created by this time lag props up rental pressure this year and next.

Two to three years#

Today's starts are tomorrow's move-ins

An apartment usually takes two to three years to go from start to move-in. So this year's rise in starts cannot hold down this year's prices, while this year's fall in move-ins squeezes the rental market right away. That is why, when policy talks about supply, you have to ask which point in time that supply belongs to.

🎒Young households#

Where the shock lands first

When tighter loan limits and higher monthly rents come at the same time, the households squeezed first are those with little savings and low income. Young single-person households are the typical case. Buying a first home takes more cash to make up for the lower LTV. Those who cannot buy lose cash every month in a market where monthly rent is more than half of leases.

First-time buyers#

The threshold of a first home

First-time purchases keep an eased LTV, but in a year when the total lending target is capped at 1.5%, banks pick whom to lend to. The lower the income, the sooner the DSR calculation cuts the limit. Even if policy makes an exception for genuine buyers without a home, the turning point is whether that exception becomes an actual loan at the bank counter.

Monthly rent share 55.4%#

Monthly rent is billed every month

Jeonse ties up a lump sum but gives it back, while monthly rent goes out every month and does not come back. In a market where the monthly rent share rose by nearly 12 percentage points in a year, young households' housing costs pile up as spending rather than assets. This difference reaches decisions about saving, marriage and having children. That is why policy treats youth housing separately.

🗳️Politics#

The bill arrives as approval ratings

In Gallup Korea's survey for the first week of September (September 1 to 3), 40% approved of the president's job performance and 51% disapproved, the lowest approval and highest disapproval since taking office. The top reason for disapproval was real estate policy, at 23%. Real estate policy also remains among the reasons for approval, at 6%. The same policy is a reason for support on one side and a reason for opposition on the other.

Feedback#

Approval ratings call for the next policy

When approval falls, the government again touches one of the four axes above. The April management plan, the June expansion of regulated areas and the August rate hike, coming at two-month intervals, show that order. Whether the next step is about loans, taxes or supply can only be known from the announcement. But whichever it is, it comes back to some cell in this map. This is where the loop closes.
