To maintain stable returns in rental property management, keeping vacancy rates as low as possible is essential. However, vacancy rates have been trending upward due to population decline and an increasing supply of rental properties. This article explains 10 vacancy reduction ideas, along with the causes of prolonged vacancies and key precautions when implementing solutions.

What Is the Vacancy Rate in Rental Properties and Why Does It Matter?

According to the 2018 Ministry of Internal Affairs and Communications "Housing and Land Survey," the total number of vacant homes nationwide was approximately 8.489 million units, of which rental properties accounted for 4.327 million units — roughly half.

Causes of Rising Vacancy Rates

  • Oversupply of rental properties: 300,000 to 400,000 new rental housing units are built each year
  • Population decline due to an aging society and falling birth rates: The population is projected to fall below 90 million by 2065

Why Maintaining Full Occupancy Matters

Prolonged vacancies reduce rental income, making it difficult to meet loan repayments and property tax obligations. Understand that full-occupancy management is the revenue foundation of rental property management.

What Are the Main Reasons Vacancies Persist?

Accurately analyzing the causes of unfilled vacancies is the first step toward effective solutions.

  • Rent is higher than the surrounding market rate
  • The property's appeal falls short of competitors (amenities, exterior, interior)
  • Insufficient collaboration with leasing agents
  • Too narrow a target demographic
  • Inadequate promotion of property information

10 Vacancy Reduction Ideas

Add amenities in high demand among prospective tenants, such as free internet, parcel delivery lockers, and video intercoms. Free internet in particular offers a high return on investment.

Idea 2: Optimize Rent Pricing

Research the surrounding market and set an appropriate rent that reflects the property's age and amenities. However, treat rent reductions as a last resort, as indiscriminate cuts will erode profitability.

Idea 3: Renovation and Remodeling

Consider investments that enhance the property's appeal, such as replacing wallpaper, updating flooring, and refreshing wet areas. Prioritize work based on cost-effectiveness.

Idea 4: Relax Tenancy Requirements

Expand your potential tenant pool by accepting foreign tenants, allowing pets, or welcoming elderly residents.

Idea 5: Improve Property Photography

Professional-quality property photos directly impact the number of viewings. Take bright, clean images and post them on listing portals.

Idea 6: Strengthen Relationships with Leasing Agents

Increase referral frequency through advertising fee (AD) incentives, regular property information updates, and effective collaboration with leasing agents.

Idea 7: Improve Common Area Appearance

Maintain thorough cleanliness of entrances, hallways, and garbage areas to enhance first impressions. First impressions during a viewing have a significant impact on the decision to move in.

Idea 8: Reduce Move-In Costs

Lower the barrier to entry by reducing or eliminating security deposits and key money, or by offering rent-free periods (free rent for a set period).

Idea 9: Review Your Property Management Company

Consider switching to a management company with strong tenant recruitment capabilities that prioritizes the owner's interests.

Idea 10: Brand Your Property

Differentiate your property through concept renovations and model room setups that highlight its unique character.

Key Precautions for Vacancy Reduction Measures

Keep the following points in mind when implementing measures.

  • Always evaluate cost-effectiveness: Calculate in advance whether the return justifies the investment
  • Avoid indiscriminate rent reductions: Once lowered, rents are difficult to raise again
  • Choose measures suited to your target demographic: Consider local area characteristics and tenant profiles
  • Combine multiple measures: Relying on a single measure limits its effectiveness

Frequently Asked Questions (FAQ)

Q. What is the most cost-effective vacancy reduction measure?

Offering free internet provides the best cost performance. An investment of just a few thousand yen per month can be expected to improve occupancy rates.

Q. How long should a rent-free period be?

One to two months is standard. Avoid going too long, as it will affect profitability — balance it against the length of the vacancy period.

Q. What budget should I set aside for vacancy reduction measures?

It is recommended to reserve approximately 5–10% of annual rental income for repairs and vacancy reduction expenses.
