Policy Loan Application Requirements for Apartments Under 600 Million KRW: Comparing Bogeumjari Loan and Didimdol Loan Limits
Key takeaways
When buying an apartment under 600 million KRW, leveraging the Didimdol Loan and Bogeumjari Loan allows you to benefit from low interest rates and DSR exemption. A practical strategy is to first lower your interest burden with a Didimdol Loan and then combine it with a Bogeumjari Loan through a combined loan structure to cover any shortfall.
If you are a non-homeowner targeting an apartment priced at 600 million KRW or less, government policy loans are the top option you should consider. This is because the loan products you can apply for and their maximum borrowing limits are determined by the evaluated property value (KB market quote, actual transaction price, etc.).
Compared to commercial bank loans, which still carry the lingering impact of high interest rates, Didimdol Loans and Bogeumjari Loans offer relatively lower interest rates and allow borrowers to choose between fixed and variable rates according to their circumstances. Furthermore, the fact that they are exempt from DSR (Debt Service Ratio) restrictions is a major advantage. Here is a clear guide covering the eligibility requirements, borrowing limits, property valuation criteria, and combined financing strategies you need to know when purchasing an apartment under 600 million KRW for owner occupancy.
What is the difference between Didimdol Loan and Bogeumjari Loan when buying an apartment under 600 million KRW?
While both the Didimdol Loan and Bogeumjari Loan are government-backed products designed to help non-homeowner households purchase homes, they differ distinctly in eligible property price, income requirements, and applied interest rates. The Didimdol Loan is an ultra-low interest product tailored for low- and middle-income families, whereas the Bogeumjari Loan offers broader income thresholds and higher home value caps.
Based on the standards outlined in the HF Korea Housing Finance Corporation Bogeumjari Loan Guide and the HF Korea Housing Finance Corporation Didimdol Loan Guide, the two programs diverge starting from their net asset limits and property price criteria.
| Category | Didimdol Loan | Bogeumjari Loan |
|---|---|---|
| Eligible Property Price | Standard 500 million KRW or less (Newlywed/Multi-child 600 million KRW or less) | 600 million KRW or less |
| Combined Household Income | Standard 60 million KRW (Newlywed 85 million KRW, Multi-child 70 million KRW) | Standard 70 million KRW (Newlywed 85 million KRW, Multi-child up to 100 million KRW) |
| Net Asset Limit | 511 million KRW or less (as of 2026) | No asset limit |
| Maximum Loan Limit | Standard 200 million KRW / First-time buyer 240 million KRW / Newlywed & Multi-child 320 million KRW | Standard 360 million KRW / First-time buyer 420 million KRW |
| LTV / DTI | Max LTV 70% (First-time buyer 80%) / DTI 60% | Max LTV 70% (First-time buyer 80%) / DTI 60% |
| DSR Application | Not applied | Not applied |
While the Didimdol Loan is harder to qualify for, it allows you to secure a lower interest rate. In contrast, because the Bogeumjari Loan does not conduct a separate net asset assessment, non-homeowner households with moderate financial assets can easily access it without friction.
Property Value Criteria of 600 Million KRW: KB Quote vs. Actual Transaction Price Deep Dive
In policy loans, the appraised collateral value of a home does not strictly equal the contract price; financial institutions look first at official market valuations. Therefore, for apartments listed on KB Real Estate, even if the actual purchase price exceeds 600 million KRW, you can still apply for a policy loan as long as the KB market price remains at or below 600 million KRW.
Confusing actual transaction prices with valuation benchmark criteria frequently causes setbacks during the application process. Financial institutions determine property value according to the following priority order:
For example, even if you sign a sales contract for 620 million KRW, if the general average KB Real Estate price for that floor plan is verified at 595 million KRW, it meets the requirement for properties priced under 600 million KRW. Conversely, even if the actual transaction price is 580 million KRW, if the KB quote stands at 610 million KRW, the property may be disqualified, making it essential to verify market quotes prior to signing a contract.
Comparing Loan Limits by Category: What Are the Actual Limits for Standard, First-Time Buyers, and Newlyweds?
As of October 2026, the actual borrowing limits for Didimdol Loans and Bogeumjari Loans are applied on a tiered basis depending on household characteristics and first-time homebuyer status. While the standard household limit for a Didimdol Loan applies to homes priced at 500 million KRW or less, the property price limit is relaxed to 600 million KRW or less for newlywed or multi-child households.
The limit differences between the two products across household types can be reviewed at a glance in the chart below.
Looking strictly at interest rates, the Didimdol Loan ranges from 2.85%~4.15% per annum, making it advantageous to prioritize. The Bogeumjari Loan rate ranges from 3.90%~5.20% per annum, which is relatively higher, but it offers outstanding fixed-rate stability compared to commercial bank mortgages, along with the major benefit of bypassing DSR restrictions. Detailed rules can also be found in the Revised Policy Loan Criteria Guide.
How to Use a Combined 'Didimdol + Bogeumjari' Loan When Borrowing Limits Fall Short?
There is a solution if the Didimdol Loan limit alone is insufficient to cover your remaining purchase balance: a combined loan (simultaneous application) strategy where you execute the Didimdol Loan first and stack the Bogeumjari Loan on top within the remaining LTV cap. This path lets you maximize ultra-low interest benefits while closing any remaining funding gap.
In this setup, the Didimdol Loan secures first-priority mortgage status, while the Bogeumjari Loan receives secondary approval through the same financial institution within the remaining LTV allowance.
| Category | When Purchasing a 600 Million KRW Apartment (Example applying 80% LTV for First-Time Buyer Newlyweds) |
|---|---|
| Total Available Borrowing Limit (80% LTV) | Up to 480 million KRW (600 million KRW × 80%) |
| Priority 1: Approved Didimdol Loan | Up to 320 million KRW (Full receipt of max newlywed limit) |
| Priority 2: Additional Approved Bogeumjari Loan | 160 million KRW (480 million KRW - 320 million KRW) |
| Result & Benefits | 320 million KRW is secured at ultra-low rates (Didimdol), while only the remaining 160 million KRW shortfall is funded via Bogeumjari, minimizing interest burden |
Applying for both loans together extends document review and approval timelines by approximately 1~2 weeks compared to a single application. Therefore, it is safest to complete the application process at least 45 days prior to your final settlement date.
What Are the Practical Tips for Preventing Deductions via MCG and Leveraging DSR Exemption Benefits?
When applying for a Didimdol Loan, combining it with MCG (Mortgage Credit Guarantee) allows you to draw the maximum LTV limit without deductions for small-tenant lease deposits, commonly known as room deduction ("bang-gongje"). (However, because room deduction exemptions via MCG are restricted for apartments located in the Seoul Metropolitan Area, prior verification is required.) Additionally, unlike commercial bank loans, policy loans are exempt from DSR regulations, meaning even if you hold existing credit loans, approval is straightforward as long as you meet the 60% DTI threshold.
By default, mortgage loans legally subtract a fixed sum (room deduction) from the loan limit to protect small-scale tenants. As a result, maximum borrowing limits are reduced by approximately 55 million KRW in Seoul and 48 million KRW in the Overcrowding Control Region of the Seoul Metropolitan Area.
| Region Category | Room Deduction Amount (As of 2026) | Deduction Status with MCG Enrollment |
|---|---|---|
| Seoul Metropolitan City | 55 million KRW deduction | Restricted for Seoul metropolitan apartments (Exceptions allowed for non-apartments, etc.) |
| Seoul Metropolitan Overcrowding Control Region / Sejong / Yongin / Hwaseong, etc. | 48 million KRW deduction | Restricted for Seoul metropolitan apartments (Exceptions allowed for non-apartments, etc.) |
| Metropolitan Cities (Excluding Gun districts) / Ansan / Gimpo / Gwangju / Paju, etc. | 28 million KRW deduction | No deduction (100% of LTV limit recognized, excluding metropolitan apartments) |
| Other Regional Areas | 25 million KRW deduction | No deduction (100% of LTV limit recognized) |
Policy Loan Application Process, Document Preparation, and Essential Checklist
To initiate a policy loan, you must complete your purchase agreement and apply 30~60 days prior to the final settlement date. Furthermore, you are obligated to move into the home within 1 month of loan disbursement and maintain owner-occupancy for 1 year. Failing to fulfill this requirement risks loan recall action.
Here are the essential items to prepare before applying:
Application progress and details can be confirmed through disclosures and reports such as Policy Loan Analysis News. The review process progresses through document submission, asset review, on-site collateral assessment, approval, and contract execution.
This guide provides general information based on policy loan systems and financial regulations as of October 2026.

Frequently asked questions
Q. Can standard non-homeowners apply for a Didimdol Loan when purchasing an apartment worth 600 million KRW?
The price limit for properties eligible for a Didimdol Loan for standard non-homeowner households is 500 million KRW or less. For homes with a purchase price or KB market value of 600 million KRW, only newlywed households (married within 7 years or planning to marry within 3 months) or multi-child households with 2 or more children can apply for a Didimdol Loan.
Q. If the actual purchase price is 580 million KRW but the KB market price exceeds 600 million KRW, is the loan still available?
Government policy loans prioritize the general average price of KB Real Estate quotes as their primary standard. Even if the actual transaction price is under 600 million KRW, if the KB market price exceeds 600 million KRW, the property may be disqualified from Didimdol and Bogeumjari Loans, so you must check the KB quote prior to signing a contract.
Q. If the Didimdol Loan limit is insufficient, can I apply for a Bogeumjari Loan at the same time?
Yes, you can. You can use a 'combined loan (joint application)' approach by securing the Didimdol Loan as the primary lien first and then applying for a Bogeumjari Loan for the remaining balance within the 70~80% LTV limit.
Q. I have several existing credit loans; can my policy loan application be rejected due to DSR restrictions?
Didimdol Loans and Bogeumjari Loans are government policy loans exempt from DSR (Debt Service Ratio) regulations. Even if you have existing credit loans, as long as you satisfy the DTI (Debt-to-Income) limit of 60%, your loan can be approved.
