Essential Pre-Contract Real Estate Checklist: 6 Reality Checks Before Buying Your First Home

When preparing to buy a home, most people start with similar thoughts.
"I like this house, but how much loan can I get?" "Should I just sign the contract first?" "What if I end up short on cash?" These questions constantly spin in your head.

Especially for first-time buyers like young professionals or newlyweds, the financial planning part often causes more anxiety than picking the house itself. On the surface, it seems like you just need the purchase price and the mortgage to line up, but in reality, you must also consider existing debt, hidden costs, monthly payment burdens, emergency funds, and contract clauses to make a truly safe purchase.

If terms like DSR, LTV, and DTI that often come up when discussing loan limits still feel unfamiliar, it's helpful to first clarify the concepts by reading The Ultimate Guide to DSR, LTV, and DTI: How Much Mortgage Can You Get on Your Salary?. That way, instead of a vague hope like "I should be able to get this much," you can make a more realistic judgment about what's possible in your current situation.

Therefore, in home buying, it's more important to first figure out "Is this a reasonable choice for my current situation?" rather than "How expensive of a house can I buy?". In this article, we'll break down the realistic checkpoints you must verify before signing a contract, explained easily even for beginners.

1. Check This Before the House Price: Recalculate Your Actual Loan Limit

Many people just look at the Loan-to-Value (LTV) ratio and think, "I can get a loan for up to 70% on this house," but this is often not the case in reality. The limit based on the house price and the limit you can actually afford can be very different.

Why It's Dangerous to Sign Based Only on LTV

LTV is simply the maximum loan ratio based on the house value; it doesn't guarantee the actual loan amount you'll receive. The actual limit depends on the review results factoring in your income, existing debt, interest rates, and maturity conditions.

You Must Also Look at DSR and Stress DSR for the Actual Limit

You can check the detailed calculation structure of DSR and Stress DSR in the Ultimate Guide to DSR, LTV, and DTI, but in practice, you only need to remember one fact.
"The limit I thought I had" and "The limit the bank actually recognizes" can be different, and the gap can be larger than expected.

Especially with the application of Stress DSR, your loan limit could be lower than before even with the same salary. So, rather than making a contract decision just by looking at an online calculator, the first step should be getting a pre-consultation based on your actual income documents and existing loan history.

2. What You Must Clear Before Contracting: Check Existing Debts and Installments

One of the first things you should do when preparing for a mortgage is to organize your existing debts. Loan reviews don't just look at the mortgage; they also factor in personal loans, credit card loans, car installments, and overdraft accounts you're already using.

Typical Items That Eat Up Your Limit

• Personal loans
  Even if the balance isn't large, it can be viewed as a burden during the loan review.
• Credit card loans and cash advances
  These are highly likely to be judged as high-interest short-term debts, acting against your loan review.
• Car installments and long-term installments
  Fixed monthly payments reduce your capacity to handle a mortgage.
• Unused overdraft accounts (Minus Tongjang)
  Even if you barely use it, depending on the financial institution, the limit itself may be seen as a debt burden, so it needs checking beforehand.

Practical Checkpoints

• Don't take out new personal loans right before signing a contract.
• Check whether to keep unused overdraft accounts open.
• Pay off credit card loans and cash advances at least a few months before your planned purchase.
• Also check your spouse's loans and installments.

If you want to increase your limit, reducing existing debt is often a more realistic solution than looking at more houses.

3. Looking Only at the Price Is Not Enough: Calculate Hidden Costs Like Acquisition Tax, Broker Fees, and Registration Fees

The money you need to buy a house isn't just "Purchase price minus loan amount." From the contract to moving in, you'll need significantly more cash than expected, and these costs generally cannot be covered by a loan.

Incidental Costs You Must Prepare For

• Acquisition tax and local education tax
  These vary depending on the house price, area, and the number of homes you own, and the actual burden can vary greatly.
• Real estate broker fees (Bokbi)
  Calculated based on the maximum rate for each transaction amount bracket, so it must be factored into your budget in advance.
• Registration fees and judicial scrivener (Beopmusa) fees
  These are fixed costs that cannot be avoided during the ownership transfer process.
• Loan execution incidental costs
  Detailed items like stamp duty, guarantee fees, and bond-related costs may arise.
• Moving and repair costs
  Wallpapering, flooring, lighting, move-in cleaning, and appliance replacement can add up to a unexpectedly large sum.

Why These Items Matter

If you sign a contract without accounting for these incidental costs, you'll run out of cash as the closing day approaches. You might end up urgently seeking personal loans or credit card loans, which could negatively impact your mortgage review. Therefore, before contracting, you must separately calculate the "total cash needed until move-in completion," not just the purchase price.

4. Getting Approved Isn't the End: Consider Your Monthly Payments and Emergency Funds

Just because your loan is approved doesn't mean the house fits your budget. What's more important is making sure your lifestyle won't collapse while handling the monthly principal and interest payments.

Set a Standard for Monthly Payments First

To avoid over-leveraging (often called 'Yeongggeul' in Korea), you must first check the ratio of the mortgage principal and interest to your actual monthly take-home pay.
Generally, keeping it under 30-35% of your net monthly income is safer for lifestyle stability.

For example, if your net monthly pay is 4,000,000 KRW (approx. 3,000 USD), the moment your housing-related payments significantly exceed 1,200,000 to 1,400,000 KRW, your living expenses, savings, and unexpected expenditures can quickly come under pressure.

Keep Your Emergency Fund Until the End

One of the most dangerous choices during the home buying process is putting all your cash into the down payment and the final balance.
It's safer to keep at least 6 months' worth of living expenses and loan payments as a separate emergency fund even after the loan is executed.

Unexpected variables like job changes, childcare, health issues, or interest rate fluctuations happen more often than you'd think. The period of surviving after buying the house is more important than the moment you buy it.

5. Final Check Before Signing: Prepare Special Clauses and a Plan B

Writing a contract when your loan limit is uncertain is the most careful point for beginners. Your final balance plan can easily be shaken by the timing of loan execution, bank review results, or eligibility for government policy loans.

Items to Check Before Signing

• Did you confirm your estimated limit through a bank pre-consultation?
• Did you check your eligibility for government policy loans?
• Did you consider the combined income of you and your spouse, rather than just your sole income?
• Have you created a cash flow statement for the funds needed up to the closing day?
• Do you have an alternative funding plan in case the loan comes out lower than expected?

Reviewing Special Clauses is Also Important

If loan approval is uncertain, reviewing special clauses when drafting the contract is crucial.
For instance, a condition regarding contract cancellation or the return of the deposit if the loan is denied can help reduce dispute risks.

Also, for areas with complex procedures like Land Transaction Permission Zones, you must verify the permission schedule alongside when you can apply for the loan. The "let's sign first and figure it out later" approach is extremely risky.

6. Quick Reality Checklist Before Buying Your First Home

Checking the items below before signing will make your financial plan much more stable.

Review Government Support Policy Loans Before Regular Mortgages

If you meet the income and home price requirements, it's better to review government policy loans before regular commercial bank mortgages. They can be more advantageous in terms of interest rates, repayment stability, and initial financial planning.

Key Products to Check

• Didimdol Loan (Stepping Stone Loan)
  Offers relatively low-interest conditions for actual first-time or non-homeowning buyers.
• Bogeumjari Loan
  Centered on long-term fixed rates, it is helpful for reducing the burden of interest rate fluctuations.
• First-Time Homebuyer Benefits
  It's good to check not only loan conditions but also potential tax reductions.

However, policy loans look at income, house price, household requirements, and actual residency requirements all together, so you should approach by plugging your situation into the conditions one by one, rather than just thinking "it might work."

Frequently Asked Questions (FAQ)

Q1. If I have a personal loan, will my mortgage application definitely be rejected?

It won't be automatically rejected. However, the repayment burden of your existing personal loan will be factored in, which may reduce your mortgage limit. Especially if your limit is borderline, even a partial repayment can change the result.

Q2. Is it always better to choose a longer loan maturity?

A longer maturity can be advantageous for lowering your monthly repayment burden. However, since the total interest paid may increase, a practical approach is to lower the initial burden and consider a pre-payment strategy later when you have extra funds.

Q3. Can I check my potential loan limit before signing a contract?

Yes. If you prepare income proof, employment documents, and existing loan records, you can check your estimated range through an advance consultation.
However, since the final approved limit may vary depending on the conditions at the time of the review, it is safer to take a conservative approach before contracting.

Q4. Does using a combined couple's income always increase the limit?

Not necessarily. Applying a combined couple's income increases the total income, which can be advantageous, but the spouse's existing loans and installments will also be factored in, so the actual outcome might be different.
