[비즈한국] On June 29, the largest private investment scale since the founding of the nation was unveiled at the Blue House Guest House. Samsung and SK are set to pour over 800 trillion won into Honam, Chungcheong, and Yeongnam over the next 10 years and beyond. Building just one semiconductor fab (production plant) costs between 60 trillion and 100 trillion won. Samsung Electronics005930 has announced up to 5 fabs in Gwangju and South Jeolla Province, while SK Hynix000660 has signaled an investment nearing 300 trillion won for memory production bases. As phrased by a high-ranking business executive, this is a 'turning point in industrial history,' comparable to the construction of the Gyeongbu Expressway, POSCO, and the capital region's semiconductor belt.
It is natural for the real estate market to be stirred up. Brokers in the Gwangju Cheomdan 3 District, a likely candidate site, report, "We were surprised to see investment demand pile in after the talk of Samsung." The negative premiums that had long weighed down the market have disappeared, and local listed companies like Gwangju Shinsegae037710 and Kumho E&C002990 saw their stocks hit daily upper limits within days.
However, the professional habit of someone who has been observing the real estate market for over 25 years is to pause for a moment amidst the excitement. There is only one question: 'Does a positive factor automatically equal rising home prices?' To give the conclusion first: sometimes it does, and sometimes it doesn't. This column is about that 'boundary line'.
Opportunity-The Root of Real Estate is Ultimately 'Jobs'
The starting point for all my analyses is always the same. What creates home prices is demand, and the root of that demand is 'quality jobs = income.' This is why Gangnam is Gangnam, and why Pangyo overtook Bundang in 10 years. When good jobs gather, people gather, and when people gather, home prices follow. There have been no exceptions.
From that perspective, the 'quality' of jobs this investment will create is unquestionable. Semiconductor fabs are not merely production plants; they are 'clusters' where material, component, and equipment companies, R&D centers, and design firms concentrate in one place. High-income permanent employees and their families, along with partner company personnel, move in. This is the exact formula by which Seoul's Magok regenerated as an R&D hub to absorb residential demand, and Incheon's Songdo boosted prices through the bio industry.
Let’s look at the regions. For Honam, the focus is front-end fabs centered on Gwangju's Cheomdan 3 District and Jangseong, South Jeolla Province. For Chungcheong, it is display and batteries in Cheonan and Asan, and packaging in Cheonan and Onyang. For Yeongnam, it is MLCC in Busan, data centers in Ulsan, and Physical AI in Saemangeum and Changwon. For the first time in history, high-tech industrial investments that were trapped in the capital region are moving south in earnest. Regional hub cities that have long been in a slump are essentially gaining the most powerful driver for housing: 'proximity between work and home.'
However, a first round of 'weeding out' is necessary here. Not all positive factors carry the same weight. If we rank them by their power to generate employment and residential demand, the order is 'Semiconductor Fab > Display/Battery > Data Center.' While gigawatt-class AI data centers have large investment scales, they actually require surprisingly few permanent staff. It would be a mistake to expect the data centers planned for Ulsan, Sejong, and Saemangeum to create the same level of residential demand as a fab. In terms of real estate, the true 'major positive factor' is the fab and the material/component/equipment cluster that moves people in large numbers.
Crisis-The 'Shadow of Positive Factors' Shown by Pyeongtaek
If we stop here, we are only seeing half the picture. We already have a vivid textbook case: Pyeongtaek Godeok.
Thanks to the positive news surrounding the Samsung Pyeongtaek Campus, Godeok was called the 'Eldorado for day laborers' and the 'Gangnam of Pyeongtaek.' Its population grew by 10,000 in a year, with 58.5% being in their 20s to 40s. At one point, 60,000 construction workers flocked there daily, even coining the term 'the million-won couple' (referring to high daily wages). But that was as far as it went. When Samsung entered into an investment 'speed adjustment' due to a slump in its foundry business in 2024, the price of an 84㎡ apartment at Godeok New Town Xi evaporated by 400 million won, dropping from 900 million to 500 million won. Unsold housing in Pyeongtaek exploded 18-fold from 361 to 6,438 units, leading to it being re-designated as an area under intense unsold housing management for the first time in 4 years and 10 months. A city that had been ecstatic over positive news collapsed at the first sign of a change in that news.
There are three lessons to take away.
First, the trap of hollowing out. In reality, Samsung's regular employees and high-income partner staff live in Dongtan, Hwaseong, or Gwanggyo, Suwon, not Pyeongtaek. This is because residential conditions like school districts, large hospitals, and cultural facilities could not keep up with the speed of factory development. "Work in Pyeongtaek, live in Dongtan." This is the cold truth that a factory does not automatically become a good residential area. A city that is bustling by day and empty at night cannot create long-term holding value for housing.
Second, polarization. Prices skyrocket within a 2km radius of the campus, but unsold inventory piles up just a little further out. Positive news acts as a 'point,' not as a 'surface' that spreads evenly. It is not about 'a fab is coming to Gwangju,' but 'which block, which station area' is everything.
Third, the counterattack of supply. The proposition I have emphasized all along—that 'prices are ultimately determined by supply and demand'—works exactly the same way here. If apartments are sold off all at once just by trusting in positive news, the moment actual demand fails to keep up with that supply, prices will collapse. The fact that 10 out of 14 apartment complexes in Pyeongtaek failed to meet their subscription quotas in 2025 is proof of this. Furthermore, local finances are also shaken. As Samsung’s performance dipped, Pyeongtaek City’s local tax revenue dropped by nearly 100 billion won, leading to the suspension of various library and road projects. The more a city relies on a single company, the greater the amplitude of its booms and busts.
The sight of Gwangju and South Jeolla-based listed companies seeing 'blind surges' even in stocks unrelated to the region is a warning sign that the same thing could be reproduced in real estate. We know all too well how chasing a rally ends.
Feasibility-There Are 10 Years Between 'Announcement' and 'Operation'
This is where we must be most objective. This investment is an ultra-long-term project that will take over 10 years. In between, there are three mountains to cross.
Electricity. Out of 13 345kV transmission grids in the Honam region, 12 will run out of capacity by 2030. The Hanbit Nuclear Power Plant Unit 1 has already stopped, and Unit 2 will end its operations this September. A semiconductor fab is a facility that cannot afford to stop even for a single second. This is why experts insist that "unstable solar and wind power are just auxiliary means, and stable power sources like nuclear power are essential."
Water. Front-end fabs use highly purified 'ultrapure water,' not just regular water. Gwangju does not even have a dedicated industrial water line. New water pipelines and purification facilities must be installed from scratch. Even the Cheomdan 3 District, considered the most likely site, is deemed unsuitable for a front-end fab due to its narrow land area.
And politics. The biggest enemy of long-term investment is a change in government. If the construction of basic infrastructure is delayed, the possibility of plans being downsized or postponed by the next administration cannot be ruled out. The 'announced 60 trillion won' and the 'actually invested 60 trillion won' are completely different stories. The real estate market always surges once on an 'announcement,' surges again on 'construction commencement,' and is only filled with actual demand upon 'operation.' If you don't understand the time lag between these three stages, you will get stuck at the peak.
From this perspective, Chungcheong and Honam are different in nature. Cheonan and Asan are 'proven job-housing proximity markets' where Samsung Display and SDI are already operating. Because the structure involves adding additional investment onto an existing ecosystem, the realization risk is lower and real estate reactions are likely to be more solid. On the other hand, Honam is a 'greenfield' starting from scratch. While the upside is the largest, the volatility and realization risks are also the highest. Even for the same positive news, 'verified markets' and 'markets with only expectations' must be judged by different standards.
Conclusion-Buy a 'City Where People Live,' Not Just a 'Factory'
To summarize: this 800 trillion won investment is a genuine opportunity that could redraw the regional real estate map. However, positive news is not a guarantee of rising home prices.
If you are an investor, check these three things.
One, residential conditions. Is the location one where school districts, transportation, healthcare, and lifestyle infrastructure follow, or is it a 'back-end workplace' that is only busy during the day? This difference is exactly what determined the fates of Pyeongtaek and Dongtan.
Two, jeonse (deposit-based rent) prices. I always call jeonse prices the lie detector for actual demand. If only the purchase price jumps due to the news but the jeonse price does not follow, it is a bubble fueled by expectations rather than actual residents moving in. You must verify a simultaneous rise in purchase and jeonse prices.
Three, timing and capital. Do you have the funds to endure the long gap between construction and operation? Going into debt to chase an 'announcement-driven' trend is the riskiest choice of all.
Ultimately, the standard for a 'smart one' (a good home) remains unchanged. It is a city where people live, not a factory; a location that possesses the self-sustaining power to keep running even if the positive news fades. Before getting intoxicated by the number 800 trillion won, check first if that city has 'a life with an evening.' Real estate always moves following people, not factories.
