Real Estate + Additional Revenue Diversification Strategy | Solar Power, Coin Laundries, Storage Units

Diversifying Real Estate Investment Revenue Streams

Real estate investment is a stable investment method with rental income as its primary revenue source, but the risks of vacancies and declining rents are always present. One strategy to counter these risks is diversifying revenue streams through real estate-based complementary businesses.

By combining rental income with utilization of underused spaces and complementary businesses, you can diversify revenue sources and increase the property's added value.

Solar Power Generation

Overview

This involves installing solar panels on the building's roof or grounds and selling the generated electricity or using it for self-consumption.

Benefits

• Stable Income: Utilizing the Feed-in Tariff (FIT) system guarantees a fixed purchase price for a set period
• Utilization of Underused Spaces: Effectively leveraging roofs and vacant land that typically generate no income
• Property Differentiation: Reduced electricity costs in common areas serve as a competitive advantage in tenant recruitment
• Environmental Appeal: Attracting environmentally conscious tenants

Points to Consider

• FIT purchase prices are declining annually, making revenue projections essential before investment
• For rooftop installation, verify the building's structural capacity and waterproofing integrity
• Declining power generation efficiency due to panel degradation over time
• Securing maintenance costs
• Consider exit strategies after FIT expiration, such as transitioning to self-consumption models or combining with battery storage systems

Suitable Properties

• RC apartment buildings with large rooftops
• Properties with good sun exposure
• Areas with few tall surrounding buildings

Coin Laundries

Overview

This involves operating a coin laundry facility in a vacant first-floor tenant space or adjacent area. The coin laundry market is expanding due to the proliferation of high-performance washing and drying machines.

Benefits

• Unmanned Operation: Minimizes labor costs and management overhead
• Stable Demand: Usage increases during rainy seasons and pollen seasons, regardless of weather
• Cash Business: No accounts receivable risk
• Enhanced Tenant Convenience: Promotes tenant recruitment by providing on-site laundry facilities

Points to Consider

• Significant Initial Investment: Costs for commercial washing and drying machines
• Requires plumbing and electrical construction work
• Must research competitor presence in the surrounding area beforehand
• Requires maintenance systems and equipment repair protocols
• Market Analysis is Critical: Surrounding demographics and competition determine profitability

Suitable Properties

• Properties with vacant first-floor tenant spaces
• Areas with high concentrations of single-person or family households
• Areas with few nearby coin laundries

Storage Units (Trunk Rooms)

Overview

This involves installing and leasing trunk rooms (storage spaces) in vacant property spaces or on the premises.

Benefits

• Effective Use of Vacant Spaces: Allows for monetization of spaces unsuitable for residential rental
• Easy Management: Fewer complications compared to residential rental operations
• Low Turnover: Tenants tend to use services long-term once they start
• Lower Exit Costs: Minimal restoration expenses compared to residential leases

Points to Consider

• Stabilizing occupancy rates takes time
• Requires security measures (surveillance cameras, access control)
• For outdoor container-type units, temperature and humidity control are challenges
• Must verify building code compliance and zoning restrictions

Suitable Properties

• Properties in or near residential neighborhoods
• Properties with available parking space
• Properties with basement or semi-basement spaces unsuitable for living but ideal for storage

Vending Machine Installation

Overview

This is the easiest method for diversifying revenue by installing vending machines in common areas or on the property grounds.

Benefits

• Minimal Initial Investment: When beverage manufacturers handle installation and management, the owner only needs to provide space
• Minimal Management: Manufacturers handle restocking and maintenance
• Enhanced Tenant Convenience: Particularly popular in properties targeting single occupants

Points to Consider

• Monthly revenue per unit is modest, typically a few thousand yen
• Power supply installation at the location is required
• Sales cannot be expected in low-traffic locations
• Aesthetic considerations

Suitable Properties

• Properties in high-traffic locations
• Properties with large numbers of tenant units
• Areas with few nearby convenience stores

Other Revenue Diversification Ideas

External Parking Lot Rental

This involves leasing unused parking spaces to external parties as monthly parking or car-sharing spaces. In urban areas, operating as hourly parking lots is becoming increasingly common.

Mobile Base Station Antenna Installation

This involves leasing your property's rooftop to mobile carriers for base station installation. While you receive rental income from telecommunications companies, installation opportunities depend heavily on property location, so it's typically initiated by carrier inquiries rather than owner solicitation.

Billboard and Advertisement Space Rental

This involves leasing wall surfaces or grounds of properties facing roads as advertisement spaces. While compliance with outdoor advertising regulations must be verified, well-located properties can generate stable supplementary income.

Important Considerations When Implementing Revenue Diversification

Balance with Primary Operations

Revenue diversification is ultimately a complement to real estate investment. Ensure that your primary rental operations don't suffer by carefully balancing management effort against returns.

Legal Verification

Verify all necessary legal procedures for each business, including zoning restrictions, building codes, fire codes, and required filings. Building approval may be required if existing structures require purpose changes.

Impact on Financing

If the property has financing, changing its purpose without lender approval may constitute contract breach. Always consult with your lender before launching new ventures.

Gradual Implementation

Rather than investing heavily all at once, a safer approach is to start small, build a track record, and gradually expand. Begin with low-risk options like vending machines or external parking rentals.

Conclusion

Revenue diversification in real estate investment is an effective strategy for leveraging underutilized assets and distributing revenue sources. By selecting methods suited to your property's characteristics and location—such as solar power generation, coin laundries, storage units, and vending machines—and implementing them gradually, you can enhance both the stability and profitability of your rental operations.
