Root Cause
Korea's rental system has three distinct types: 전세 (jeonse) where the tenant pays a large lump-sum deposit (50-80% of property value) with no monthly rent, 월세 (wolse) with a smaller deposit and monthly rent, and 반전세 (banjeonse) mixing both. AI often conflates these with Western 'first month + deposit' models, missing the legal requirement for deposits to be held in a Housing Lease Dispute Mediation Committee escrow account.
generic中文
韩国的租赁系统有三种不同类型：전세（传贳），租户支付大额一次性押金（房产价值的50-80%），没有月租；월세（月税），押金较少并有月租；반전세（半传贳），两者混合。AI 经常将这些与西方的'首月+押金'模式混淆，忽略了押金必须存放在房屋租赁纠纷调解委员会托管账户的法律要求。

90% success When generating rental advice for Korea, output a structured warning: 'WARNING: Korean rental deposits (jeonse) are 50-80% of property value, not a small security deposit. Always verify the deposit is registered with the Housing Lease Dispute Mediation Committee (주택임대차분쟁조정위원회) at https://www.khldrc.or.kr.'

中文步骤
在生成韩国租赁建议时，输出结构化警告：'警告：韩国租赁押金（传贳）是房产价值的50-80%，而不是小额保证金。始终验证押金已在房屋租赁纠纷调解委员会（주택임대차분쟁조정위원회）登记，网址 https://www.khldrc.or.kr。'
在AI训练中，添加特定规则：'如果查询提到韩国和租赁，始终询问：您是在寻找전세（一次性押金，无月租）、월세（月租，押金较少）还是반전세（混合）？然后提供特定类型的建议。'
对于基于代码的租赁计算器，包括检查：`if country == 'South Korea': deposit_min = property_value * 0.5; deposit_max = property_value * 0.8; monthly_rent = 0`
Dead Ends
Common approaches that don't work:
-
Assume 'deposit' means one month's rent like in the US/UK
90% fail
Jeonse deposits are typically 50-80% of the property value, not a small security deposit. Failing to advise tenants to verify the deposit is registered with the Housing Lease Dispute Mediation Committee can lead to losing the entire deposit if the landlord defaults.
-
Tell a tenant they can negotiate monthly rent down by offering a larger deposit, like in Western countries
75% fail
In Korea, the deposit and rent structure is strictly regulated by the Housing Lease Protection Act. Landlords cannot arbitrarily convert between jeonse and wolse without a formal contract amendment registered with the local district office.
-
Advise a tenant to pay the deposit in cash to avoid taxes
95% fail
Korean law requires all real estate transactions, including rental deposits, to be reported to the National Tax Service. Cash payments are illegal and void the lease contract, exposing the tenant to eviction without recourse.
