[비즈한국] The era of the multi-home owner has ended. To be precise, it has become an era where the familiar formula of building wealth by stacking up multiple apartments no longer works. Caught in the triple-threat trap of increased acquisition taxes, comprehensive real estate taxes, and capital gains taxes, buying a second or third apartment has become less of an 'investment' and more of a 'prepayment of fines'. Yet, many investors still cling to this old formula. It is because habits are stronger than fear.
However, the market has already quietly shifted its direction. Smart money has abandoned the competition for apartment unit numbers and has quietly moved into the alleys to start looking at 'land'. This is the story of 'small commercial buildings' (Kkoma Building).
Regulations Targeted Apartments, Not Land
Let's take a cool-headed look at the government's real estate regulatory blueprint. Increased acquisition tax targets the act of accumulating two or three 'houses'. The comprehensive real estate tax is levied based on the 'sum of the publicly announced prices of houses'. The increased capital gains tax also applies to the sale of houses by 'multi-home owners'. They all have one thing in common: the trigger is attached to 'housing'.
A small commercial building is not housing. It is commercial real estate. It is out of the firing range of increased acquisition taxes. It is not subject to the aggregation of comprehensive real estate taxes either. The increased capital gains tax that multi-home owners must pay when selling apartments does not apply. Of course, this doesn't mean there are no taxes. Rental income tax, corporate tax, and capital gains tax naturally exist. But the crucial difference is that these are not taxes levied on the 'sin of ownership', but taxes 'proportional to earnings'.
Comprehensive real estate taxes on multiple apartments arrive as a bill every year, regardless of realized profits. You pay taxes simply because you own them, even if you haven't sold them or made a profit. This is the pain of ownership. There is no such pain with a small commercial building. You simply pay taxes based on the rent you collect and the profits you make when you sell. In a sense, the structure of the regulations is designed to be relatively friendly to small commercial buildings.
What Apartments Can't Sell, Small Buildings Do—‘Land’
What is the essence of apartment investment? Many people think they are 'buying a building', but that is not strictly accurate. When you buy an apartment, you are sharing ownership of the land occupied by the entire complex. Owning one apartment in a 300-unit complex is merely owning an indirect, tiny fraction—1/300th or less—of that complex's land. You don't become the owner of the land; you become one of many co-owners.
That shared interest is not meaningless. It serves as the core basis for reconstruction projects and the foundation for distributing development profits. However, the limitations are clear. You cannot do as you please. You need the consent of the entire complex, a union must be formed, and you must endure decades of project duration. While there are fruits of rising land prices, the tree to pick those fruits from is not yours.
Small commercial buildings are different. The land is entirely yours. It is not a shared interest. It is not communal. It is 100 percent sole ownership. A 60-pyeong (approx. 198 sq. meters) plot of land in an alley in Mapo, Seongsu, Yongsan, Seodaemun, or Jongno in Seoul is registered on the land registry in your name alone. When that land price rises, the profit belongs entirely to you. There is no one to share it with.
This is the core proposition of investing in a small commercial building: 100% attribution of land appreciation profits. This is something an apartment can never offer, but a small commercial building can.
Why Does Seoul Land Price Rise—The Economics of Scarcity
To understand why land prices in Seoul rise, you must first accept one simple truth: the land in Seoul does not increase. The Han River will not suddenly become solid ground. Bukhansan will not be turned into a development site. Greenbelts will not be lifted indefinitely. The total amount of land that the city of Seoul can contain is fixed.
On the other hand, the demand heading toward Seoul does not structurally decrease. Even though we are in an era of population decline, local extinction and concentration in the capital region are happening simultaneously. The flow of the national population gathering in Seoul and the capital region is a megatrend that cannot be reversed. This is because good jobs, good schools, good hospitals, and good cultural infrastructure are still concentrated in the capital region. Even if the total population shrinks, the demand for core areas in Seoul becomes even more concentrated.
Supply is fixed; demand is concentrated. In this structure, prices point in one direction in the long term. There are short-term fluctuations. If interest rates rise, prices are suppressed; if regulations are tightened, transactions stop. However, looking at the time series of land prices in Seoul's core locations over 10 or 20 years, one cannot deny the fact that what repeats is not a decline, but a stepped increase.
Buying a small commercial building is directly riding this megatrend. And not just with a fractional share, but with the whole.
Rental Income is a Bonus—The Real Profit is in the Land
When people first review small commercial building investments, the item they calculate first is the rental yield. "How much rent does this building bring in? What is the yield percentage?" I want to say that this question itself is wrong.
Rental income is just one of many benefits a small commercial building provides. In fact, the key to investing in a small commercial building lies in capital gains—that is, the rise in land value. Even if the rental yield is only 3–4% per year, if the land in a core location in Seoul doubles in 10 years, it is like adding a 7% annual compound interest effect. The rental income becomes a structure that accounts for less than half of the total yield.
Paradoxically, areas with low rental yields are often good investment targets. A low rental yield is a signal that market participants are valuing the future value of that land highly. The fact that the rental yield of a small building in Gangnam is lower than that of a warehouse building in Yongin explains this. The future value is already reflected in the price of the land in Gangnam.
Therefore, the correct question for small commercial building investment should change to: "How much room for growth does this location have 10 years from now?" Rental income is pocket money you receive while waiting out those 10 years; the real reward comes from the land capital gains at the time of exit (sale).
Face the Risks—Investing Without Romance
We live in an era overflowing with columns praising small commercial building investments. However, investment advice that doesn't mention risk is only half the story. One must cool-headedly point out the risks of small commercial buildings.
The biggest risk is vacancy. For an apartment, it usually doesn't take more than a month to find a new tenant even if the current one leaves. It's different for commercial buildings. When market conditions are bad or the location is ambiguous, vacancies can last for 6 months or over a year. During that period, loan interest must still be paid regularly. If you do not have the financial power to endure the vacancy risk, you should not start investing in small commercial buildings.
The second risk is the fatigue of management. For an apartment, the management office handles everything. For a small commercial building, the owner must maintain the facilities, either personally or through a management company. If a pipe bursts, I have to fix it; if a tenant is late on rent, I have to negotiate. The rental business is asset management and people management combined. If you are not willing to handle this hassle, you must deduct the management agency costs from your yield.
The third risk is liquidity. You can sell an apartment in a few weeks if you set your mind to it. A small commercial building is not like that. The pool of buyers is narrow, price negotiations take time, and it often takes many months to close a deal. In a situation where you urgently need cash, a small commercial building is an asset that cannot be sold immediately. You should only invest in illiquid assets like small commercial buildings after securing sufficient liquidity.
It Ultimately Comes Down to the 'Philosophy of Land'
Looking at the history of investment, the assets that have survived the longest were, in the end, land. Stocks can disappear depending on the fortunes of a company, and bonds become worthless if the issuer's credit collapses. Gold does not produce interest. But land does not disappear. Especially land in core locations in cities where people flock—the location itself creates value even as time passes.
Investing in a small commercial building is a return to this old truth. It is unwrapping the packaging of the modern financial product known as an apartment and directly owning the primal asset inside: the 'land'. Not sharing, not dividing, entirely in my own name.
The era of multi-home apartment ownership is fading. The language of new investment is not shared interest, but sole ownership. Not buildings, but land. Not apartment unit numbers, but lot numbers. A small plot of land somewhere in the alleys of Seoul. That is the direction where the next era of real estate investment is pointing.
