In South Korea, there is a concept called "jeon-se", which can be roughly translated into "lump-sum housing lease" or "long-term rental deposit". It goes like this: An owner leases their real estate for a lump-sum for a year or so. When the contract is not renewed and expires, the owner must give the money back to the tenant, who is moving out.
My parents recently showed me an opportunity to buy a house using jeon-se. The house's price is 300 million KRW(South Korean Won). I can use 50 million KRW(out of 170 million of my assets), but I can pay the rest using the tenant's jeon-se deposit(250 million KRW)
My parents insist to buy it because they speculate the price will increase, and they want me to have a house in my name. While I don't want to miss this opportunity, it seems risky. What if I can't find the next tenant in time? Then I might be in huge debt to banks to return the deposit.
How can I manage this kind of risk?
