Are there any companies that can bid on my behalf, since the process of real estate auction conducted by the court does not seem easy? If so, how much is the agency fee?

Yes, there are companies that bid on real estate for auction on your behalf. Although it is difficult to say, the market rate is about 3% of the winning bid price, excluding the bid deposit, the remaining amount after the winning bid, and taxes and other fees that must be paid. For properties with a small bid price, there are agencies that make a minimum commission amount.
