chapter 1: Anatomizing the '3+3+3' Mandate: The Structural Flaws of a Well-Intentioned Proposal

the recently proposed so-called "3+3+3" Residential Tenancy Protection Act amendments aim to improve tenant housing stability, but a closer analysis of its components reveals that it is at odds with the fundamental workings of the marketplace and is likely to have serious unintended consequences. each of the bill's provisions could act as a mechanism to inherently restrict landlords' property rights and distort their incentives to participate in the market.

1.1. Dismantling the 9-year residency rule: stagnating the market beyond stability

the core of the amendment is to extend the tenant's residency period to a maximum of nine years by changing the existing '2+2 years' right to renew the contract to a '3+3+3 years' structure, which guarantees a maximum of four years. this is more than just a term extension, it fundamentally redefines the landlord's control over the asset. nine years is more than a short-term financial plan; it's the equivalent of a person's life cycle. during this time, the landlord is effectively denied the opportunity to use the property as a primary residence, sell it at market value, or participate in development plans such as rebuilding.

this powerful constraint imposes a "shadow price of illiquidity" on all new rental contracts. rational landlords will no longer set rental deposits based solely on current market rates. instead, they will demand compensation for the opportunity cost and risk of tying up the asset for the next nine years. this includes future inflation, possible interest rate fluctuations, and even the cost of losing the opportunity to sell at the peak of the real estate market. with rent increases capped at contract renewals, all of these risk premiums would be locked into the security deposit at the outset of a new tenancy, when the tenancy relationship begins. as a result, the mere signal that the bill will pass could cause security deposits on new rental contracts to skyrocket to levels that far exceed the natural uptick in the market.

1.2. The Burden of Greater Transparency: The Paradox of Disclosure Encouraging Supply Dislocation

the amendment requires landlords to disclose to tenants not only their national and local tax payment certificates, but also their health insurance premium payment history. In addition, when a home is transferred, the new landlord's personal and financial information must be notified to the existing tenant. this is intended to protect renters from financially insolvent landlords.

however, these regulations are likely to place undue administrative and psychological burdens on unprofessional private landlords, who make up the majority of the domestic rental market. the inconvenience of having to disclose sensitive personal information and the complexity of the process will act as a "professionalism barrier" for individuals who have been running a rental business on the side. rather than deal with increased regulation, they are likely to choose to exit the rental market altogether, either by selling their properties and reducing their rental stock, or by shifting to less regulated rental markets. this process can drive smaller individual landlords out of the market and reorganize the market around a small number of larger corporate landlords who are better able to comply with regulations. these corporate landlords are more likely to shy away from the capital-eating effects of subletting in favor of rent-to-own models with clearer returns, resulting in a simultaneous contraction in the diversity and volume of rental supply.

1.3. 70% Security Deposit Cap: An Unintended Consequence of Well-Intentioned Regulation

the bill seeks to protect renters from the risk of so-called "canned subletting" by capping rental deposits at 70% of the home's value. on its own, this provision makes sense in terms of protecting renters. however, when combined with the other provisions of the bill, it has a compounding effect.

for landlords already looking to leave the rental market due to the mandatory nine-year contract, the 70% cap gives them another compelling reason to abandon the rental model. the biggest risk for landlords is the nine-year asset freeze, and the 70% cap is simply a regulation that further limits their financing flexibility. Adding additional regulation without addressing the underlying issue of nine-year risk could be a catalyst for landlords to harden their resolve to move to renting or flipping. this could have the paradoxical effect of making the risk of canned rentals irrelevant as the market voluntarily eliminates them. the regulation is likely to be a secondary control on an already dying market.

chapter 2: Predicted market response: a cascade of scarcity and increased costs

according to economic principles, strong regulation triggers behavioral changes in market participants, and a "nine-year charter ban" would set off a predictable chain reaction across supply, pricing, and market structure.

2.1. Huge supply freeze: accelerating the disappearance of charter listings

supply in the charter market was already shrinking even before the amendment was discussed. according to Asil, a real estate big data platform, the number of apartment rentals in Seoul fell by 23.3% from 31,814 on January 1 to 24,418 as of October 17. this is the result of the cumulative impact of existing regulations such as the '10-15 Real Estate Measures'.

if a 9-year contract is introduced in this situation, the decline in supply will accelerate at an unprecedented rate. nine years is equivalent to effectively removing a home from the market's available inventory for almost a decade. a "supply cliff" would emerge as homes that have been steadily coming on the market in two-year cycles would be locked into long-term contracts. with the bill's passage in sight, landlords will rush to take back units or convert them to rentals before the law takes effect, which could cause a short-term shortage of rental units. while the previous 23.3% decline was a response to market pressures, the 9-year law has the potential to act as a powerful amplifier to those pressures, more than doubling the rate of supply decline.

2.2. The flight to liquidity: the structural entrenchment of 'renting'

the shift from chartering to renting, or "gentrification," is already an irresistible market trend. according to data from the Court Registration Information Plaza, the share of renting transactions in total lease transactions rose from 40% in 2020 to 47.1% in 2022 after the implementation of the Rent 2 Act, surpassed 50% in 2023, and broke 60% this year for the first time ever.

the data clearly demonstrates that landlords are actively moving away from the risks of the charter model, which ties up large deposits for long periods of time, and toward a rent-to-own model, which ensures stable cash flow and flexibility. if the Rent to Own Act of 2020 triggered this trend, then the nine-year rule could be the final nail in the coffin for the charter system. rather than risk nine years of capital erosion and limited returns, landlords will decide it makes sense to opt for predictable rental income. the table below clearly shows how increased regulation has accelerated the trend towards gentrification.

year key regulatory event total lease transactions share of charter contracts share of lease/reverse lease deals 2019 before the Rent2 Act - approx. 59 approximately 41 2020 lease2 Act in effect - about 55 approximately 45 2021 law enforcement impact continues - about 53 approximately 47 2022 rising interest rates begin - 52.9 47.1 percent 2023 rent share exceeds 50 - 46 54 2024 (YTD) rent share exceeds 60 - approx. 39 approximately 61

note: Percentage of transactions may vary slightly depending on the point in time and statistical criteria, but are intended to show the overall trend.

this table is strong evidence of how regulatory intervention has changed the structure of the market. year 9 will push the market even faster toward the end of this trend.

chapter 3: Déjà vu all over again: unlearned Lessons from the 'Rent2 Act' of 2020

the current proposed legislation is not a new endeavor, but a dangerous extension of a policy experiment that has already proven to be a failure. a review of the outcomes of the two laws introduced in 2020 (right to renew and rent control) provides a clearer picture of what the nine-year system will bring.

3.1. Retrospective on Failure: Dual Pricing and Induced Inflation

a joint study by the National Land Research Institute and the Civil Law Society clearly shows the negative effects of the Rent 2 Law. the price of a full apartment in Seoul, which had risen by 3.86% in the year before the law was implemented, more than doubled to 8.13% in the year and a half afterward. this is because landlords, fearful of future rent increases, tried to bundle four years' worth of increases into new contracts. as a result, the 'dual pricing' phenomenon has become entrenched, with the deposit gap between renewal contracts, which are subject to a 5% cap, and new contracts, which reflect market prices, widening dramatically.

this data is 'conclusive evidence' that this type of market intervention does not stabilize prices, but rather fragments the market and passes on all costs to the most vulnerable - new tenants. nine-year leases will create an even more extreme class divide: protected existing renters and punished new renters.

this creates the paradox of the "locked-in tenant". renters who have enjoyed nine years of stable housing under the protection of the law are paradoxically setting themselves up for a trap. for nine years, their home is removed from the market's circulating supply, which reduces supply across the rental market and causes prices to skyrocket. nine years later, when they need to move due to a life-cycle change, such as a job change or a child's education, they are forced to leave the price-control bubble they've been protected in and face the super-expensive market they helped create. short-term stability will eventually lead to more unaffordable housing cost shocks in the long run.

3.2. The amplification effect: why 9 years is exponentially worse than 4 years

market conditions in 2024 are much weaker than in 2020. new housing supply is scarce, and the adverse effects of previous regulations have accumulated in the market. whereas the 2020 legislation operated on a relatively stable supply base, the 2024 proposal is a bomb dropped on a market already experiencing supply shortages and price instability.

and while the nine-year timeframe is just over twice as long as four years, the impact on the market is exponential, not arithmetic. the risk premium for landlords, the supply freeze effect, and the incentive to exit the market explode as the timeframe increases. the table below clearly illustrates how the intensity of regulation increases with each bill.

category pre-2020 rent2 Act of 2020 (2+2) 2024 Amendment (3+3+3) longest guaranteed residency customary 2 years 4 years 9 years number of contract renewals none 1 time 2 times rent Increase Cap none no more than 5% at renewal no more than 5% at renewal (maintained) landlord obligations basic obligations accept renewal requests disclosure of personal information, such as building fees, and additional information notices when transferring homes market impact stable surge in rental prices, decrease in listings, and dual pricing loss of charters, skyrocketing property values, accelerated gentrification (expected)

this comparison makes it clear that the proposed legislation is not just an improvement, but an extreme intensification of existing policy failures. as one real estate expert warned, "With new supply scarcer than it was in 2020, the shift to longer-term contracts will lead to an even faster decline in rental units and skyrocketing sublet prices to levels not seen before."

chapter 4: The Perfect Storm: Weak Markets and New Regulations Collide

the proposed amendments couldn't have come at a worse time. when introduced into a market already fragile from other regulatory policies, it could create a "perfect storm" of unimaginable destructiveness.

4.1. Cumulative regulatory burden

the market is already absorbing the shock of the "10-15 Real Estate Measures". the measures tightened the residency obligation to prevent gap investments and applied DSR (debt-to-income ratio) to rental loans for the first time. these are both measures that simultaneously tighten both supply and demand. the increased residency requirement reduces investment home purchases, cutting off potential rental supply, and the DSR on rental loans reduces effective demand by limiting renters' ability to obtain financing.

in other words, the rental market is already in a "dual squeeze," with supply and demand being squeezed from both sides. adding a strong supply-constraining policy like the nine-year rule to this environment could be the catalyst that triggers the collapse of an already fragile market structure. the negative effects of each policy will not simply add up, but will synergize with each other, plunging the entire market into unpredictable chaos.

4.2. Supply-side bottlenecks

the fundamental solution to housing stability is a sufficient supply of housing to meet demand. however, the market is currently producing fewer new homes than it did in 2020. focusing on demand-side regulations, such as longer tenure, while ignoring this fundamental supply shortage is misleading. it's like trying to regulate the amount of time each person can sit at the table without thinking about increasing food production when there is a shortage of food and people are starving. unless the underlying supply imbalance is addressed, any rent control will eventually shift the burden to renters in the form of higher prices and more competition.

chapter 5: Alternative Pathways to Housing Stability: from Controls to Incentives

to avoid the crises that a regulatory one-size-fits-all approach will create, we need to explore sustainable alternatives based on market principles. this means a policy shift towards achieving housing security through incentives and increased supply, rather than control and mandates.

5.1. Refocusing on the root causes: scarcity, not insecurity

the root cause of renters' housing insecurity is not a short contract term, but an absolute shortage of rental properties compared to the number of homes they want to live in. In other words, housing insecurity is a symptom of an underlying supply-demand imbalance called scarcity. the proposed legislation makes the mistake of trying to treat the symptom and actually exacerbating the cause of the disease.

5.2. Framing a sustainable solution

a realistic solution should focus on restoring the supply function of the market. market experts suggest that housing stability is best achieved through increased supply and tax flexibility. this means policies that incentivize the voluntary provision of quality rental housing, rather than imposing punitive mandates on landlords that lock them out of the rental market.

specifically, consideration could be given to reviving landlord registration incentives to stimulate private rental supply, and granting tax incentives to landlords who offer long-term leases. these policies align the interests of landlords with the goal of housing stability for renters. more supply provides renters with more choice, which naturally leads to price stability, creating a virtuous cycle. this is the way to move from a zero-sum game through controls to a positive-sum game through incentives.

chapter 6: Conclusion: A Warning of a Predicted Crisis

nine-year leases have the noble goal of protecting renters, but behind them lies a misunderstanding of market dynamics and a disregard for recent policy failures. when analyzed, it is clear that far from bringing stability, this legislation would create a compounded crisis on three levels

  1. supply collapse: A supply shock in which rental units disappear from the market at an unprecedented rate.

  2. price explosion: Hyperinflation of new charter deposits as demand concentrates on the few remaining units.

  3. structural disruption: a structural realignment that accelerates the demise of the charter system and pushes all renters into the more expensive rental market.

the 'renters' triple-dipping' and 'unprecedented price spikes' that experts warn of are not mere hyperbole. they are a logical and inevitable corollary of the proposed legislation's structure. to push through this policy in the face of such clear evidence and predictions would be to intentionally put the very people it seeks to protect at serious and ongoing risk. careful reconsideration is urgently needed to ensure that the warnings of "charter spikes like we've never seen before" do not become a self-fulfilling prophecy.
