7 Reasons Apartment Investments Fail and How to Succeed: Yield Calculation and Property Selection

Discover the 7 most common causes of apartment investment failure in Japan, plus success strategies covering yield calculation and smart property selection.

About 3 min read

Apartment investment is a popular asset management strategy that can generate stable monthly rental income, but while some investors succeed, many others encounter failure. Knowing the common failure patterns in advance and taking the right preventive measures is the first step toward success.

This article provides a comprehensive overview of the seven causes of failure in apartment investment, four key points for success, a proper understanding of yield, and how to find income-producing properties.

7 Reasons Apartment Investments Fail

① Poor Location

No matter how good the floor plan or amenities are, demand for a property varies greatly depending on its location. Locations too far from train stations or commercial facilities, or areas saturated with competing properties, make it difficult to secure tenants. Location selection must also account for disaster risk.

② Design That Doesn't Match the Local Market

Even a high-end apartment will struggle to attract tenants if the rent is set far above the local market rate. Clearly defining your target demographic and designing to a grade appropriate for the area is essential.

③ Choosing the Wrong Construction or Management Company

Poor construction quality leads to tenant complaints and early move-outs. Similarly, a management company with low service standards will keep occupancy rates down. Since construction and management fees are significant costs, compare your options carefully rather than cutting corners.

④ Cash Flow Problems

Unexpected expenses—such as additional construction costs, emergency repairs, and loan repayments during vacancy periods—are an ever-present reality. A financial plan with sufficient buffer and a reserve fund are indispensable for stable apartment operations.

⑤ Deferring Maintenance and Repairs

Repairs made after a problem becomes serious are far more costly. By addressing issues early and maintaining a regular repair schedule, you can keep costs down while preserving the property's appearance and safety, allowing even an older building to remain a desirable place to live.

⑥ Ineffective Vacancy Reduction Strategies

Large-scale renovations often take a long time to recoup. Start with cost-effective measures first, such as relaxing tenancy conditions (e.g., allowing pets or elderly residents) and switching to a management company with stronger tenant acquisition capabilities.

⑦ Inadequate Handling of Tenant Issues

Problems such as rent arrears, noise complaints, and tenants absconding directly impact cash flow and occupancy rates. Selecting a management company experienced in dispute resolution and establishing a preventive response manual in advance are critical steps.

4 Key Points for Successful Apartment Investment

① Thorough Information Gathering

Staying diligent about gathering information on local demographics, competing properties, and future development plans to avoid mismatches between location and target tenants is the foundation of success.

② A Financial Plan With Sufficient Buffer

Keeping the loan-to-cost ratio at 70–80% of the initial investment is ideal. The more equity you have, the greater your resilience against vacancy risk, and the more flexibility you gain to implement tenant acquisition measures such as zero security deposits, zero key money, or rent-free periods.

③ Careful Selection of Construction and Management Companies

  • Construction company: Compare proposals, construction costs, and track records across multiple firms
  • Management company: Verify the scope of management, response speed, number of units managed, and reviews from other owners

④ Proactive Measures Against Future Risks

  • Stabilizing rental income: Consider rent guarantee services or sublease agreements
  • Stricter tenant screening: Screen out prospective tenants with a high risk of causing issues
  • Repair planning: Begin setting aside repair funds from the time of new construction

Essential Knowledge: Understanding "Yield" in Apartment Investment

The Difference Between Gross Yield and Net Yield

Gross YieldNet Yield
FormulaAnnual Rental Income ÷ Property Purchase Price × 100(Annual Rental Income − Annual Expenses) ÷ (Purchase Price + Ancillary Costs) × 100
CharacteristicsDoes not account for expenses. The figure typically listed in property listingsActual earning power after accounting for expenses
Calculation Example¥6M ÷ ¥50M × 100 = 12%¥5M ÷ ¥54.5M × 100 = approx. 9.2%

Even at a gross yield of 12%, once expenses are factored in, the net yield drops to approximately 9.2%—a difference of about 3%. Always base investment decisions on net yield.

Yield Comparison: New vs. Used Apartments

New ApartmentUsed Apartment
Typical Yield Range2–5%3–7% (6–10% for properties over 10 years old)
CharacteristicsHigher purchase price results in lower yieldLower purchase price results in higher yield
Minimum ThresholdAt least 3% requiredCalculate individually for each property

4 Key Points to Watch When Evaluating Yield

  1. Yield is only a guideline — Vacancies will cause actual returns to deviate from projections
  2. Net yield declines over time — Plan for rising repair costs and rent reductions as the property ages
  3. Exercise caution with unusually high gross yields — These may signal underlying problems such as excessive maintenance costs
  4. Don't rely on yield alone — A low vacancy rate (i.e., stable income) is equally important

Factors That Affect Yield

FactorDescriptionBenchmark
Rental IncomeFluctuates with vacancy rate and rent revisions
Initial CostsVaries significantly depending on land acquisition and new vs. used property
Property Tax, etc.Annual taxesAssessed value × 1.7%
Management & Cleaning FeesFees paid to the management companyApprox. 5% of rental income
Repair CostsOngoing maintenance and upkeep expensesApprox. 7% of rental income

How to Find Income-Producing Properties

  • Consult a real estate company — Access to local market knowledge and off-market listings
  • Real estate listing websites — Easily compare a large number of properties. Using multiple sites is more effective
  • Attend seminars — Gain specialized knowledge and access to off-market properties. Attend seminars from multiple companies to cross-reference information

5 Steps to Purchasing a Property

  1. Develop an investment plan — Clarify your goals and objectives; aim for 20–30% equity and 70–80% financing
  2. Search for properties — Make a comprehensive assessment of yield, area, location, surrounding environment, and management approach
  3. Consult with a bank about financing — Undergo screening based on your investment plan
  4. Execute the purchase agreement — Ensure you understand the important matters explanation before signing. Don't forget to confirm the earnest money deposit
  5. Take delivery of the property — After payment and registration are complete, receive the documents and keys

3 Key Points for Selecting a Property

  • Verify the income-based valuation — Research transaction benchmarks using the Ministry of Land, Infrastructure, Transport and Tourism's Land General Information System
  • Identify properties with low vacancy risk — Evaluate the surrounding environment, accessibility, amenities, and management system comprehensively
  • Consider asset value — Land value and management condition also influence loan screening outcomes

Conclusion

The success of an apartment investment is largely determined by the decisions made at the outset. By understanding common failure patterns in advance and making sound choices in location selection, financial planning, management company selection, and yield calculation, you can achieve stable long-term returns.
