Last updated: About 2 min read

A condominium is one of the biggest purchases in life. Even if you believe you have considered everything carefully, it is not uncommon to feel regret or view the purchase as a mistake after buying. In this article, we provide a comprehensive explanation of common condominium purchase mistakes and how to solve them.

What are common examples of condominium purchase mistakes?

Mistake 1: Problems with choosing the property

Many buyers lose sight of their decision criteria after seeing too many properties, or later find that the space is no longer sufficient because their family grows or remote work becomes necessary. It is important not to take every explanation from the real estate company at face value and to confirm the condominium's internal rules in advance as well.

Mistake 2: Problems with the surrounding environment

Many issues can be prevented through on-site research before purchase, such as hazard risks tied to the location, the loss of convenient facilities, worsening public safety, or a dark route home. It is essential to check the surrounding environment multiple times, changing between day and night as well as weekdays and weekends.

Mistake 3: Parking problems

These are issues that can be hard to notice during a viewing, such as too few parking spaces, height and weight restrictions, or the inconvenience of mechanical parking systems. Be sure to confirm the number of spaces, the restrictions, and the parking format before purchase.

Mistake 4: Financial problems

In these cases, fixed costs after purchase increase more than expected, such as when income falls because of a job change, borrowing exceeds a safe level with no down payment, or repair reserve fund payments rise year by year. Do not calculate only the loan repayment amount; estimate the monthly cost including management fees, repair reserve fund contributions, and taxes as well.

Mistake 5: Noise problems

Footsteps from the floor above or noise from roads and trains may become a concern after moving in, even if the property seemed quiet during the viewing. Checking the thickness of party walls and floors, confirming whether concrete is used, and choosing a condominium with as many residents of a similar profile as possible can help reduce risk.

Mistake 6: Neighbor problems

These are interpersonal frictions unique to shared housing, such as overly watchful residents, violations of pet rules, or unconventional neighbors. Because direct confrontation can create a risk of resentment, the basic rule is to work through the management company if a problem arises.

Solutions learned from condominium purchase mistakes

Be thorough in gathering information

Checking the management company's registration status (which can be confirmed through the Ministry of Land, Infrastructure, Transport and Tourism's "Condominium Management Company Registration Register") and even the resident situation is the strongest tool for preventing mistakes.

Create a detailed financial plan

Estimate future expenses including fixed asset tax, city planning tax, and the timing of large-scale repairs (roughly every 12 years as a guideline). If you choose a variable-rate mortgage, a repayment simulation based on rising interest rate scenarios is also essential.

Keep lifestyle changes in view

To prepare for unexpected changes such as job transfers, childbirth, or caregiving responsibilities, prioritizing properties with strong asset value and locations that are easier to sell can also help you avoid long-term mistakes.

Points where mistakes are more likely with new, used, and nearly new properties

  • New: Because you buy before completion, the actual condition is unclear. Resident conditions and day-to-day usability cannot be fully understood in advance.
  • Used: Checking management conditions and repair history is essential. Properties built under the old earthquake-resistance standard (before 1981) face stricter mortgage screening.
  • Nearly new used: It is important to confirm the reason for sale. In some cases, problematic properties are put back on the market after only a short period.

Frequently asked questions (FAQ)

Q. What should I do first to avoid regretting a condominium purchase?

A. The first step is to organize your budget, target area, and essential requirements, then conduct on-site checks at different times of day and on different days of the week while also confirming the reliability of the management company.

Q. How can I check for noise problems in a used condominium?

A. Check the thickness of the party walls and floor concrete, and visit in the morning and evening so you can experience the actual living noise for yourself.

Q. Is there any way to prevent repair reserve fund increases?

A. Before moving in, confirm the long-term repair plan and the schedule for step-by-step increases in the reserve fund. Condominiums without a clear plan carry higher risk.

Q. What should I do if I run into neighbor trouble in a condominium?

A. Direct negotiation carries a risk of creating resentment. As a rule, you should work through the owners' association or the management company.
