Defect, Permit, and Tax Checkpoints to Review Before Purchasing

I bought a building recently.

When people hear this, they usually let out exclamations mixed with envy. This is because owning a decent building in a prime location makes it seem as though monthly rent would flow in steadily just by breathing, and worries about retirement would be over. In the past, when the formula for real estate prices to rise dominated, simply buying a building in a good location and holding onto it was enough for its asset value to increase on its own. Perhaps all an investor needed was "money to buy."

However, the rules of the game in the commercial real estate market have now completely changed. If you rush in based solely on the building's appearance or immediate rental yields, you are likely to get held back by unseen risks and suffer significant losses.

In reality, successful building owners who survive in the market and secure genuine profits check three invisible "essential conditions" before signing a purchase agreement—that is, before taking action after buying. If these conditions are not taken care of in advance, even if you buy a decent building, your assets may leak away like water being poured into a bottomless pit, resulting in a loss.

Physical Conditions: Did you find the invisible 'defect mines'?

Many investors believe the race is over the moment they sign the building purchase agreement. They often celebrate by buying drinks for friends, thinking they bought it for less than the market price. However, the real game begins the day after the final payment is made. This is why you must examine the internal framework and foundations before the exterior.

Business is already killing me, but now the store leaks whenever it rains. I can't hold out any longer.

Mr. A, a novice building owner who had acquired a decent small building and was facing his first rainy season, lost sleep due to protest calls from tenants. This was caused by unseen structural defects and exterior wall leaks. With sales already plummeting due to a consumption slump, the leaks dealt a fatal blow, causing the anchor tenants, unable to tolerate the situation any longer, to pack their bags one after another, demanding contract termination and compensation for damages. They found a pretext to escape by citing the landlord's violation of the duty to repair under civil law.

Word of mouth spreads quickly in commercial districts. Once rumors circulated that “that building leaks and is poorly maintained,” finding a subsequent tenant became incredibly difficult. The moment the monthly cash flow is cut off and only interest on the vacancy remains, the building degenerates from an asset into a “money-eating monster.” If a structural diagnosis reveals severe cracks or leaks and the cost of reinforcement work is excessively high, the purchase itself must be reconsidered, or the sale price must be adjusted.

Legal Conditions: Can Floor Area Ratio and 'Permit Regulations' Be Controlled?

The key to increasing a building's value lies in 'value-up' (new construction and remodeling). Location is merely an excellent 'starting line'; the finish line record depends on the building owner's planning skills. While success stories of creating value by purchasing aging buildings and remodeling or rebuilding them often fill the media, in reality, there are far more tales of heartbreaking failure caused by a lack of legal knowledge. This is because the moment permits are blocked due to a failure to meet building code and parking lot regulations, the investment capital becomes tied up, leading to massive losses.

Mr. B is a prime example, having impulsively purchased an old boarding house building after being tempted by the offer that "buying it and remodeling it into a commercial space will be a huge success!" Mr. B attempted to change the building's use to open a cafe, but encountered an unexpected obstacle: the requirement to secure additional parking spaces under the Parking Lot Act. Unable to increase the number of parking spaces due to the narrow plot size, his permit was ultimately rejected, leaving him trapped in a quagmire where he is only paying interest on vacant lots without ever having started leasing. As this case illustrates, incorrectly manipulating detailed provisions of laws such as the Parking Lot Act or the Building Act can completely block the approval process.

New construction is no easy task either. When demolishing an old building to construct a new one, the applicable sunlight access setback regulations or stricter building codes can reduce the available gross floor area compared to the existing structure. Furthermore, there is a hidden risk of skyrocketing construction costs due to business restrictions under district unit plans, insufficient septic tank capacity, or the installation of additional escape staircases required by fire safety regulations. This is why you must review preliminary designs and verify permit approvals with the relevant district office before signing the purchase agreement.

Tax Conditions: Have you finished the 'after-tax rate of return' simulation?

It is common for those who choose the path of 'new construction' to build a new structure on land to suffer setbacks due to unexpected tax issues. If documentation of expenditures—ranging from design fees to overall construction costs—is not strictly managed, it can lead to a massive tax burden upon future transfer.

In particular, the selection of ownership based on the exit strategy must be completed starting from the purchase and new construction phases. In the case of assets held in an individual's name, the capital gains tax burden may be higher than expected depending on the holding period and the nature of the asset, and failure to properly keep documentation of construction costs may result in tax disadvantages.

While corporations are subject to the corporate tax system, which can be advantageous depending on the circumstances, the burden of acquisition tax may vary based on the region and characteristics of the assets, and additional taxes, such as dividend income tax, may arise during the process of transferring corporate funds to individuals in the future.

As such, when undertaking reconstruction or major renovations, if you do not calculate the after-tax return—including unforeseen comprehensive real estate tax or capital gains tax upon sale—you will end up experiencing "deficit management," where there is a profit on paper but an empty account. Therefore, it is advisable to cross-verify with two or three tax accountants before signing a contract or proceeding with the project.

The person who owns the building and the person who manages the building

We refer to those who own commercial properties or buildings as "building owners," but successful building owners now define themselves as "space business entrepreneurs." The days of simply handing over keys and checking monthly rent payments are over. Interest rates remain high, consumption trends change at the speed of light, and the lifespan of trendy hotspots is becoming increasingly shorter. It is commonplace for yesterday's prime location to become today's deserted alley.

Ultimately, the difference between successful and unsuccessful building owners lies in 'how thoroughly risks were controlled prior to the purchase.' 'Value-add,' which has recently emerged as a major trend in the investment market, is essentially a series of management activities aimed at maximizing Net Operating Income (NOI) by filling vacancies, attracting attractive businesses, and systematizing building management. This is because what investors are buying is not the building itself, but future cash flows.

Only by breaking free from the sweet illusion of rental income and calmly filtering the three major conditions—defects, permits, and taxes—before purchasing and executing can you protect your assets and generate true, loss-free "substance." However, since the outcomes of real estate investment and development can vary significantly depending on the specific circumstances of each asset, individual reviews with architects, tax accountants, and legal experts must precede the purchase. Will you remain merely an owner with your name on the land registry, or will you become a true manager controlling risk? The choice rests with the investor.
