Wooden apartment buildings are a property type often chosen as an entry point into real estate investment. While their low construction cost makes it easier to secure attractive yields, occupancy rates can suffer if you do not understand the characteristics of the structure. In this article, we explain the advantages and disadvantages of wooden apartment buildings from an investment perspective, along with practical points for selecting a property.
Why is investment in wooden apartment buildings attracting attention?
The main reason wooden apartment buildings are chosen as investment properties is their low acquisition cost and high yield potential. Compared with reinforced concrete (RC) and steel-frame (S) structures, construction and acquisition costs are lower, so the gross yield is higher even with the same rental income. In addition, because they are typically two-story buildings that do not require elevators, management costs can also be kept to a minimum.
What are the investment advantages of wooden apartment buildings?
- Lower rent and management fees make them easier to lease: Initial costs, including security deposits and key money, also tend to be lower, which helps attract tenants
- They have humidity-regulating properties: The moisture absorption and release characteristics of wood help stabilize the indoor environment and suppress mold and dust mites. This can also appeal to tenants with allergies
- There is little dead space, so the effective living area feels larger: Because there are fewer beams, floor plan flexibility is higher and the sense of usable space is greater
What disadvantages should you understand as investment risks?
- Lower sound insulation: There is a risk of tenant turnover due to noise problems. However, this can be mitigated by using sound-insulating materials and cushioned flooring
- Less efficient heating and cooling: Because they are more breathable, heating and cooling costs tend to rise, affecting tenants' running costs
- Fire and earthquake-resistance risks: Wooden structures are more vulnerable to fire, and properties built under the old seismic standards may raise concerns about earthquake resistance. It is important to choose properties built after the June 2000 revision to the Building Standards Act
Two checkpoints when choosing a wooden apartment building
1. Building age (whether it was built in or after June 2000)
The June 2000 revision to the Building Standards Act strengthened seismic standards for wooden houses. If you are selecting an investment property, we recommend using properties built after this revision as your benchmark.
2. Surrounding environment (whether there are noise sources nearby)
In wooden structures, where sound insulation is lower, properties near railway lines, main roads, factories, or entertainment districts face higher noise risk. Check the surrounding environment during viewings and choose a location where management costs can be kept under control.
Frequently Asked Questions (FAQ)
Q1. How large is the difference in investment yield between wooden and RC structures?
In the same area and at the same scale, wooden properties often deliver gross yields that are about 1% to 3% higher because acquisition costs are lower. However, it is important to compare the effective yield after including repair costs and management fees.
Q2. What are the risks of buying an older wooden apartment building?
The main risks are earthquake resistance, repair costs due to aging, and higher insurance premiums. Properties built before 1981 under the old seismic standards require particular caution.
Q3. How can sound insulation be improved in a wooden apartment building?
It can be improved through renovations such as adding sound-insulating materials, installing soundproof sheets, and switching to cushioned flooring. Carry out the work after calculating the cost-effectiveness.
Q4. What is the statutory useful life of a wooden apartment building?
Under tax law, the statutory useful life is 22 years. However, with proper management, many properties can remain in use for 30 to 40 years or more.
Q5. Which should you invest in, wooden or RC structures?
The answer depends on your capital scale, target yield, and management workload. Wooden structures are suited to a smaller budget and a focus on higher yield, while RC structures are better suited to long-term stability and a lower management burden.
