how lending regulations will change in 2025, realistic ways to borrow more money against your home, and what to look out for
what do you do when you've already maxed out your home equity line of credit with your bank, but you need urgent business or living expenses? I remember Kim, a 40-something self-employed business owner who came to me for advice not long ago. her sales were increasing, but she didn't have enough cash to buy anything right away. when she went to her main bank, she was told that DSR regulations prevented them from lending her more money. For house hunters or solopreneurs who have a home but are cash-strapped, the banking threshold is too high. But there's a workaround: subordinated mortgages. Today, we're going to take a deep dive into this hidden card of the financial world, subordinated mortgages, from A to Z, especially with the regulations changing in 2025

conclusion and Summary
1. what is a subordinate mortgage and how does it work?
what is a subordinated mortgage? In simple terms, it's taking out a second loan against your home. when you buy a house, you usually get a loan from a bank (the first lender), which puts a first lien on your home - the right to get paid first. a second mortgage means leaving this first mortgage in place and borrowing money from second and third lenders based on the value of your home minus the first mortgage (residual value)
it is mainly handled by secondary financial institutions such as savings banks, capital, insurance companies, peer-to-peer finance, and lending companies, and its main advantage is that you can raise additional funds even if you already have a mortgage. if your house is worth 1 billion won and your first loan is worth 400 million won, you can borrow additional money by pledging some of the remaining 600 million won as collateral. the interest rate is usually higher because the bank has a higher risk of losing the money than the first loan.
there are two main situations where this loan is utilized. first, it's used to fill in the gap when you don't have enough LTV to buy a home. Second, it's used when you already own a home and need additional funds for living expenses or a business. in recent years, borrowers who have been blocked from further borrowing in the first tier due to DSR rules have increasingly turned to business mortgages in the second tier
2. lending Regulatory Changes and Market Outlook for 2025 (Stressed DSR Phase 3)
the year 2025 is expected to be a turbulent time for lending markets. governments are pulling out stronger regulatory cards to manage household debt. if you're considering a subordinated mortgage, you need to understand the following regulatory changes.
stress DSR Phase 3 Implementation (scheduled for July 2025)
the biggest change is the phasing in of the stressed debt service coverage ratio (DSR). The DSR is the ratio of your principal payments to your annual income, plus an additional rate (the stress rate) that reflects the risk of future interest rate increases to calculate your borrowing limit.
starting in July 2025, we will implement a third phase of the Stress DSR. currently, only 50% of the stress rate is included in Tier 2, but 100% will be included in Tier 3. this means that the amount you can borrow will be significantly reduced
comparison of how the Stress DSR changes across tiers
categorywhen it appliespercentage of stressed rate reflectedapplies to phase 1 february 2024 to 25 bank Tier 1 tier 2 september 2024 to 50 banking facilities, credit facilities (including tier 2) tier 3 july 2025 (planned) 100 mortgages, credit loans, and other loans from all financial institutions
some analyses show that a borrower with an annual income of 100 million won taking out a 30-year mortgage loan could receive more than 100 million won less under the third phase of the stress DSR. In particular, other loans may be included in the scope of the regulation from the third phase, so the limit reduction could be even greater if the borrower has a negative passbook or card loan.
2Stop the tier 2 balloon effect
as the first-tier banks raise their lending thresholds, demand is pushed to the second-tier banks, creating a balloon effect. in response, financial authorities are tightening regulations on the secondary financial sector. in the past, savings banks and others had laxer DSR standards than banks (40% for banks, 50% for 2Fs), but now they are being subjected to the same standards or are tightening their own screening
as a result, subordinated mortgage approvals are likely to become more challenging as we move into the second half of 2025. Those in need of funding will need to either plan ahead in the first half of the year, before the regulations tighten, or have a strategy to quickly secure the best lender on their terms.
3. the key advantages of subordinated mortgages (LTVs and limits)
so why do so many people seek out subordinated mortgages with higher interest rates? the biggest reason is the LTV (loan-to-value) limit.
Loopholes in LTV regulations (up to 85%)
currently, LTV limits for conventional mortgages in regulated areas such as speculative hotspots are very strict, ranging from 40-50%. this means that even if you collateralize a KRW 1 billion apartment, you can only borrow KRW 400-500 million. however, if you utilize a business subordinated mortgage from a secondary financial institution, the story is different.
if the property is recognized as a business operation, the LTV can be up to 80% to 85%, depending on the lender. for example, if you have a senior loan of 400 million won (40% LTV) on a 1 billion won apartment, you can borrow up to 8.5 billion won (85% LTV) with a subordinated loan, which means you can borrow the difference of 4.5 billion won
of course, in this case, the actual amount you receive may be reduced due to room deductions (deduction for prioritized payment of small rental deposits), but the main attraction is that you can create a limit that is impossible with a regular household loan.
DSR exception (business loans)
business loans are relatively free from DSR restrictions, which is the biggest barrier to household loans. Since business loans are classified as business funds rather than household funds, they are judged based on RTI (rental to income ratio), business income, and estimated income, not DSR. Therefore, even freelancers or sole proprietors who have difficulty proving their income may be able to secure additional limits if they have a business license (after a certain period of time)
4. how to Use the Money (Life vs. Business)
subordinate mortgages are divided into two main categories based on the purpose of the funds: life savings and business funding. you should choose a strategy that fits your situation.
life Stability Fund (Employed, Unemployed)
if you are an office worker, housewife, or unemployed without a business, you can borrow for living expenses.
limit: In the past, there was a limit of 100 million won per year, but there has been confusion over the recent relaxation and tightening of regulations. as of 2025, each lender's policy determines the limit within the LTV and DSR range, but there are still some lenders that have a limit of KRW 100 million per year due to self-regulation of multifamily housing or secondary financial institutions. some lenders require headquarters approval for expenses over KRW 100 million
uses: You can use it for medical expenses, education, home repairs, repaying other loans, etc. however, it cannot be used to purchase a home, and the loan may be recalled if you purchase an additional home within a certain period of time after the loan is executed
characteristics: Interest rates are lower than business loans, but they are subject to DSR regulations, so if you have a high debt-to-income ratio, you may not qualify.
business funding (sole proprietorships, corporations)
if you have a business license, you can apply for a loan for business purposes.
limits: Up to 80-85% LTV to secure the highest limit available
terms: You'll need to have been in business for at least three months, but some lenders may make exceptions for more than one month or for new businesses. You may need proof of revenue or a business inspection to prove you're actually running a business
note: You can't use the loan for non-business purposes, such as buying a home or gambling. lenders require proof of use (tax invoices, purchase receipts, labor expense logs, etc.) within three months of loan disbursement. failure to do so will result in stiff penalties, including full recovery of the loan and restrictions on financial transactions for the next 3-5 years
5. compare rates across lenders and the impact on your credit score
subordinated secured loans have higher interest rates than tier 1 lenders, so careful comparison is essential.
interest rate levels (as of 2025)
tier 1 (banks): late 3% to mid-4% (based on seniority, subordinated has limited availability)
tier 2 (savings banks, insurance companies, mutuals): mid 5% to 9% vs. if you have good credit and enough collateral, you can get into the 5-6% range, but if your credit score is low or your LTV is tight, you may see rates closer to 10%
capital: 6% to mid-10%. Easy process and good availability, but rates are a bit higher.
P2P/Lending: 10% to 19.9%. considered a last resort if institutional financing is not available, but interest rates are very high.
credit score impact
in the past, there was a perception that borrowing only from tier 2 lenders would cause your credit score to plummet, but the reform of the credit scoring system from a rating system to a scoring system has mitigated the penalty. Now, borrowing at what percentage rate has a greater impact on your credit score than simply where you borrow from
however, it's still lower than it would be with a tier 1 lender. In particular, having more savings bank or capital loan holdings increases your chances of being turned down when you try to switch to a tier 1 lender in the future. Therefore, it's better for your credit to borrow all your money from one source at once, rather than spreading it out over multiple sources
6. loan application process and required documents
subordinated secured loans have a more flexible underwriting process than conventional loans, but there may be more documentation to prepare.
here's what to expect
line of creditinquiry: Get an approximate limit and interest rate based on your home address, market value, and income information. consider using a household lookup system that doesn't leave a credit report.
compare and consult with financial institutions: Compare the conditions of savings banks, capital, unit cooperatives, etc. Even for the same collateral, the limit varies depending on the financial institution's valuation criteria (KB market price, actual transaction price, appraisal value, etc.
document submission and application: prepare and submit the required documents and sign the loan agreement (affidavit). these days, you can often do this electronically on your mobile.
screening and due diligence: the lender reviews the submitted documents and, in the case of business loans, conducts due diligence to ensure that a physical business location exists.
setup and execution: The lender records a subordinate mortgage on the deed and receives the loan funds. if you have an existing high-interest loan, it may be executed on the condition that you pay it off.
list of required documents
the required documents vary for individuals and businesses
common documents:
iD (national ID, driver's license)
resident registration card, original resident registration (including address changes)
seal certificate, seal stamp (or signature verification)
title deed (house document)
tenant list (to verify the presence of tenants)
additional documents for employees:
additional documents for business owners:
copy of business license
proof of income amount
vAT tax standard certificate (last 1-2 years)
certificate of payment of national/local taxes
business premises lease (if leased)
confirmation of major insurance coverage (if required)
7. reasons for denial and tips to increase your approval rate
not every applicant will be approved for a loan. Know the top reasons for rejection and prepare ahead of time
top denial reasons
history of late payments: Being currently delinquent or having an excessive history of recent short-term late payments is fatal. late payments on telecom bills or small payments can also hurt your chances.
excessive debt to income: even a business loan can be denied if too much debt relative to income raises questions about your ability to repay, especially if you have a lot of credit card and cash advance usage.
insufficient collateral value: If your senior loan is already worth more than 70-80% of the market value, or if the bid-to-value ratio (the rate at which a property sells at auction) is low in your area, you won't be able to get additional equity.
encumbrances: If there are foreclosures, garnishments, or liens on the deed, you won't be able to borrow unless you can get them lifted.
tenant issues: If the tenant won't show the property, or the tenant's security deposit is so large that there's no residual value, it's difficult to proceed.
tips to increase your approval rate
ditch your primary bank: The secondary market is the realm of secondary lenders. it's to your advantage to use a specialized agent or platform that compares products from a wide range of savings banks and capital companies.
utilize estimated income: Sole proprietors and freelancers who don't file tax returns can use health insurance payments or credit card spending to convert their income into estimated income to demonstrate DSR or repayment capacity.
consolidate yourdebt: If you propose a consolidation loan that combines multiple small loans (card loans, credit cards) into a single, subordinated mortgage, lenders may approve it if they believe it will improve your ability to repay.
8. caution: Identifying rogue lenders and managing risk
the subordinated mortgage market is highly asymmetric, making it an easy target for rogue intermediaries and fraudsters.
characteristics of rogue lenders and how to recognize them
demanding upfront fees: anyone who asks you to deposit money upfront as an upfront fee, guarantee fee, or credit control fee to process your loan is a 100% scam. legitimate counselors don't get paid by lenders and don't pass on fees to customers.
unconditional approval: Avoid claims of unconditional approval for people with bad credit or late payments.
app installs: If a caller sends you a URL from an unknown source to install an app, it's most likely a hacked voice mail.
verification: Make sure the company and its counselors are legitimately registered by checking Pine or the Better Business Bureau.
risk management: a double-edged sword
a subordinated loan can be a firefighter to put out an urgent fire, but it can also be an interest rate bomb.
have anexit strategy: Because of the high interest rates, you should plan ahead for a short-term use of 1-2 years rather than a long-term use and then pay it off through increased business income, home sale, low-interest refinancing, etc.
auction risk: If you fall behind on interest payments, junior creditors may file for auction sooner than senior creditors. this is because junior creditors are further down the pecking order and want to collect before the collateral loses value
9. frequently asked questions (FAQs)
Q1. Can I get a subordinated loan if I have tenants living in the property?
A. It is possible, but the limit is greatly reduced. the tenant's security deposit is often considered a senior right to the bank, so you can only borrow up to the amount of [house price - senior loan - tenant's security deposit]. Also, if you have tenants, lenders often require their consent (such as a certificate of free residence), which can be tricky in practice.
Q2. Can I apply if I am unemployed or a housewife?
A. Yes, you can. if you have difficulty proving your income, you can use your credit card usage history (annualized amount) or health insurance premium payment history to be recognized as estimated income. however, the loan-to-value (LTV) limit may be lower than that of a business loan, and the loan is intended for living expenses.
Q3. Can I take out a personal business loan and use it for living expenses?
A. As a general rule, business mortgages should only be used to fund your business. if you are found to have used the loan for living expenses, stock investments, or purchasing another home, the loan will be immediately repaid and you may be registered as a financial disorderly person. however, it is okay to use the loan to refinance an existing high-interest business loan or to pay for labor, materials, etc. required for business operations. 9
Q4. My credit score is in the 600s, is this possible?
A. Second lien secured loans have relatively low credit score thresholds. If your score is in the 600s (NICE), you may be eligible for a savings bank or capital. however, the lower the score, the higher the interest rate, and if you're in the 500s or lower, you may have to turn to peer-to-peer or lenders. 15
Q5. Will my business loan be reduced if I'm in Stage 3 of the Stress DSR?
A. Stress DSR is, in principle, a regulation that applies to household loans. Therefore, mortgages taken by sole proprietors for business purposes are not subject to DSR regulation or are subject to other criteria (RTI, etc.), so the direct impact of limit reduction is small. However, if you are taking out a loan for household purposes (living expenses), you will be directly affected by Stress DSR Phase 3 and your limit will be significantly reduced. 8
10. conclusion and summary
subordinated mortgages are a powerful financial tool for securing liquidity by maximizing the equity in your home, especially as an alternative to tier 1 lending, which is stifled by LTV and DSR regulations, offering entrepreneurs the breathing room of 85% LTV and employees the opportunity for a nest egg.
however, the upcoming implementation of the third phase of the Stress DSR in 2025 and the tightening of regulations in the secondary market will further increase the lending threshold. Therefore, if you need funds, it is important to move proactively, taking into account the regulatory timeline. You should also calculate whether you can afford the cost of higher interest rates, and make sure to proceed through a trusted institutional lender.
don't just take the money because you need it, but use it wisely with a clear repayment plan, proof of use, and a strategy to minimize costs by comparing rates. we hope this article helps you get started on your money journey.
