Hello, this is Cheongchul Law Firm.

Many buyers purchase officetels after being told that "yields are guaranteed" or "rental income will be stable," only to find that promised returns never materialize. We summarize when an officetel sales contract can be cancelled based on yield shortfall, fraud, or mistake under Korean civil law.

1. Can a mere yield shortfall justify contract cancellation?

2. When advertising or explanations rise to "fraud" or "mistake"

3. Interim loan misrepresentation and cancellation

4. Living-type accommodation (saengsuk) use disputes

5. Key evidentiary issues and how Cheongchul can help

1. A Mere Shortfall in Returns Rarely Justifies Cancellation

Korean Supreme Court rulings hold that operating methods and yield prospects for income-producing real estate are primarily matters for the investor to judge. Therefore, the result that "returns were lower than expected" alone is rarely sufficient ground for cancellation. Some degree of exaggeration in sales advertising is treated as customary trade practice.

2. "Fraud" or "Mistake" Exception — Specific False Statements, Not Mere Advertising

However, if the seller made specific false statements about material facts of the transaction, cancellation may be reviewed under Civil Code Article 110 (fraud) or Article 109 (mistake):

• Stating that a lease has already been concluded with a specific tenant when it has not

• Falsely representing guaranteed fixed returns

• Citing prices or rents far removed from objective market values as if they were facts

The legal issue is whether the motive of the transaction was incorporated into the contract beyond mere advertising.

3. Misrepresentation of "Interest-Free Interim Loan" and Cancellation

Because interim loans typically cover a substantial portion of the sales price, a contract conditioned on loan availability may treat that condition as a material element, opening the door to mistake-based cancellation. Lower court rulings have recognized cancellation where sales staff misrepresented loan availability and the buyer relied on that explanation. Conversely, where the "interest-free loan" advertising lacked concrete procedures and the issue was simply non-performance of loan brokerage, courts have rejected cancellation. The decisive factor is what was actually explained at the time of contract, not the mere fact that the loan ultimately did not materialize.

4. Living-Type Accommodation Sold as a Residential Property

Living-type accommodations (saengsuk) are statutorily lodging facilities, but in practice they are often marketed as freely usable for residence, causing disputes. Outcomes split as follows:

• Cancellation difficult: If the contract clearly states "living-type accommodation," notes the difference from residential buildings, and addresses lodging business registration or change-of-use issues

• Cancellation arguable: If the buyer clearly expressed a residential purpose and the seller, knowing this, represented that residence was freely possible — fraud or mistake may be argued

In short, the contract's stated use and whether the buyer's motive was incorporated into the contract are the decisive factors.

5. What Matters Is What You Were Told When You Signed

In officetel sales disputes, the central question is not "whether returns fell short" but what the buyer was told and reasonably believed at the time of contract. Preserve sales brochures, model house materials, conversations with sales agents, KakaoTalk messages, and texts from around the contracting period — these are critical evidence.

Officetel sales-contract cancellation cases turn on how facts are framed and which legal theory is chosen. If you face such a dispute, the real estate and construction attorneys at Cheongchul Law Firm are ready to assist from the initial review through strategy.
