Mid-Payment Loan: Funds & Interest Costs
A construction loan (Jungdo-geum Daechool) is a loan from a bank that helps you cover the installments of the total purchase price when you buy an apartment. In this post, we're going to dive deep into the eligibility requirements, how the interest is structured, and exactly how much cash you'll need to have on hand.
How Much of the Sale Price Can You Borrow and What Are the Requirements?
Typically, the 60% of the total sale price is paid in installments of 10% over six payments, disbursed as the structural work progresses. You can only apply if you have fully paid your down payment and have your sales contract in hand. The bank will only lend you the money if a guarantee is issued by the Housing & Urban Guarantee Corporation (HUG) or the Korea Housing Finance Corporation (KHFC). If the apartment's sale price exceeds 900 million KRW, HUG may limit the issuance of guarantees, so you need to plan your finances conservatively before you apply.
There are limits on how many guarantees one household can have, and often, only those who are not homeowners or who are selling an existing home are eligible. The maximum loan amount varies depending on whether the area is designated as a Speculation Overheating Zone, so you absolutely must check the guidelines provided by the developer's designated bank. Also, if the complex has a mandatory occupancy period, keep in mind that you won't be able to rent it out right away to recoup your funds when you move in.
What's the Real Cost Difference Between "Interest-Free" and "Interest Deferred" Loans?
The final cost you actually pay depends heavily on whether the developer covers the interest or if you have to pay it all at once when you move in. With an interest deferral plan, you don't pay the interest accrued during construction, but that entire lump sum is charged to you at move-in, meaning you take on the risk of interest rate fluctuations.
| Category | Interest-Free Terms | Interest Deferral Plan | Deferred Payment Settlement |
|---|---|---|---|
| Interest Burden | Paid entirely by the developer | Paid as a lump sum at move-in | Paid during the sales process |
| Interest Rate Risk | None | Borne by the borrower | Borne by the borrower |
| Perceived Sale Price | Lower | Higher | Moderate |
Even if the sale price is the same, the interest terms can lead to tens of millions of KRW in extra costs, so you must ask these questions when visiting the model home. Especially during times of high interest rates, the interest deferral plan can affect your Debt Service Ratio (DSR) calculation, potentially causing issues when you need to secure your final payment.
What to Do and What Papers You Need at Each Loan Stage
You'll need to head over to the designated model home or bank branch on the date set by the developer to submit your paperwork. Usually, the first disbursement doesn't happen until several months after you sign the contract, and that's when you'll need to turn in your seal certificate and proof of income.
- Visit the model home or the partner bank on the scheduled date.
- Submit the original sales contract and your income verification documents.
- Pay the guarantee fee to the insuring agency and sign the bank's agreement.
- The bank will directly deposit the funds into the builder's account on each scheduled disbursement date.
If you miss the paperwork deadline, you could face late fees or even have your contract canceled, so it's smart to keep checking the text messages from the developer. If you're a stay-at-home parent or a freelancer with no formal income, you can use your credit card spending history or health insurance payment records to prove your income instead.
How Income and DSR Rules Apply to Your Loan
Since the interim loan itself is backed by guarantees from places like the Housing and Urban Guarantee Corporation (HUG), it's generally more flexible regarding the Debt Service Ratio (DSR) rules compared to a standard mortgage. However, you need to be careful because when you switch to the final payment, your personal income and existing debt load will be scrutinized very closely.
If you already have a line of credit or an auto loan, your loan limit might be lower than you expect, so you should check this beforehand. Families with lower annual incomes sometimes use joint ownership or bring in family members with income to meet the qualification standards.
What to Watch Out For When Moving or Reselling After the Loan
If the builder goes bankrupt or construction gets delayed, your financing costs can snowball quickly. Also, during the resale restriction period, you simply cannot change the ownership title. Even if the complex allows resale, you still need the bank to approve the transfer, meaning both the buyer and seller must go to the bank to handle the debt assumption process.
When reselling a pre-sale unit, you must clearly state in the special terms who is responsible for settling any interest that has already accrued to avoid future disputes. If the buyer's credit score doesn't meet the requirements during the interim loan transfer, the deal could fall through, so you should make sure to check the possibility of guarantee approval before signing anything.
Frequently Asked Questions
When Do I Start Paying Interest on My Interim Loan?
With the interest deferral option, you don't pay monthly; instead, the principal and interest are settled all at once during your designated move-in period. However, if you have a truly interest-free deal, you won't owe anything at all.
Will Leaving a Job or Changing Jobs Affect My Loan?
If your employment status was already verified and approved when the loan was first issued, most monthly payments will proceed as scheduled even if you leave your job later. That said, when you switch to the final closing loan at move-in, your updated income and employment status will be re-evaluated.
Can I Get This Loan Even If My Household Members Own a Home?
It's possible if you are a first-time homebuyer who agrees to sell your existing property. Otherwise, the requirement is that you must be without any property.
