Last updated: About 2 min read

Rental properties that are more than 40 years old offer attractive rents and spacious layouts, but concerns about equipment quality and earthquake resistance can make prospective tenants hesitant. From an owner’s perspective as well, preserving the value of older properties, managing them properly, and securing tenants are important management issues. This article explains the characteristics of properties that are more than 40 years old and the key points of managing them.

What are the benefits of living in a rental property that is more than 40 years old?

Rent is lower than the market average

Once more than 40 years have passed since construction, the property value generally stabilizes, and there is usually little room for it to fall further. For tenants, this makes it easier to find a larger property or one in a better location within the same budget. Owners can also maintain stable occupancy by setting rents appropriately.

More spacious layouts and Japanese-style rooms

Properties built in an era when land was more readily available are often designed with larger floor areas than modern newly built properties. Some also feature larger tatami mats in Japanese-style rooms, and many offer ample storage such as closets and overhead compartments.

What are the drawbacks of living in a rental property that is more than 40 years old?

Equipment standards are lower

Compared with new properties, the number and quality of facilities are lower. However, because the extent of refurbishment and renovation differs from property to property, it is important not to make broad assumptions and to confirm the actual condition during a viewing. From the owner’s side, updating equipment is an effective way to strengthen competitiveness.

Properties built under the old earthquake-resistance standards require careful review

Buildings constructed before the 1981 revision of the Building Standards Act, which introduced the new earthquake-resistance standards, were built under the old standards. However, “old earthquake-resistance standards = dangerous” is not an accurate equation, because safety varies depending on ground conditions, the state of the structure, and whether seismic reinforcement work has been carried out. It is important to confirm whether a seismic diagnosis has been performed and whether reinforcement has been completed.

Soundproofing and insulation may also be weaker

Older buildings may have less insulation material, making it easier to hear noise from neighboring units. In some cases, this can be improved through DIY measures such as soundproof carpets or sheets, insulating window film, and heat-blocking curtains.

What should you check when choosing a property that is more than 40 years old?

Check the maintenance condition during the viewing

The presence or absence of regular maintenance often has a greater impact on living conditions than the building age itself. During a viewing, be sure to check for creaking floors, the cleanliness of water-related areas, and whether equipment is functioning properly. On the owner’s side as well, consistent cleaning and repairs are the foundation of vacancy prevention.

Confirm whether seismic work has been carried out

Even for properties built under the old earthquake-resistance standards, having seismic work already completed provides greater peace of mind. If it has not yet been done, confirm whether there are plans to carry it out in the future. Seismic diagnosis and reinforcement can also help improve property value.

Frequently Asked Questions (FAQ)

Q. Do properties that are more than 40 years old have low earthquake resistance?

Buildings constructed before 1981 follow the old earthquake-resistance standards, but safety differs significantly depending on the ground, the structure, and whether seismic reinforcement has been carried out. We recommend checking the results of a seismic diagnosis.

Q. Is it easier to negotiate rent for older properties?

In general, owners of older properties tend to be more flexible. However, this cannot be said across the board, because properties that have already been refurbished or renovated may have higher value.

Q. Is it acceptable to move into a property that is over 40 years old if it has been renovated?

If the interior and equipment have been updated, the living environment can be close to that of a new property. However, we also recommend checking the condition of the piping and structural frame during the viewing or with the real estate company.

Q. What can owners of older properties do to prevent vacancies?

Regular cleaning, equipment updates, seismic diagnosis, and appropriate rent setting are the basics. Renovation to enhance property value is also an effective option.
