Frequently asked questions
Common questions about commercial building transactions in Korea.
Ask another questionHow much financing is available for a building?
Financing depends on the property value, intended use, repayment capacity, and each lender’s review criteria.
Do interest rates vary by bank?
Yes. Compare the total cost, expected limit, and repayment terms, not only the headline rate.
Should I lower the rent to fill a vacancy?
Not automatically. Review the asking terms, target tenant, fit-out condition, and competing supply first.
Is now a good time to buy?
Review the price, lease status, financing terms, vacancy risk, and holding plan together.
Can foreign buyers purchase commercial buildings in Korea?
Yes, subject to the applicable reporting, tax, funding, and foreign-exchange procedures.
