01Reasons for the Increase in Renovations of Used Properties and Vacant Houses in Fussa City

Fussa City, Tokyo, is a town in Nishi-Tama where American-style streetscapes coexist with a downtown lifestyle, adjacent to the Tama River and Yokota Air Base. Single-family residential areas spread along the Ome Line, and the natural beauty of the Tama River is close at hand.

Single-family homes developed during the Showa era are now entering a generational transition period, reaching 40 to 50 years of age. This is why the option of “buying a used single-family home and renovating (or remodeling) it to fit one’s lifestyle” is expanding in Fussa City.

02Reasons for Renovating Vacant Houses and Used Properties

In recent years, the Japanese housing market has expanded options not only for new builds but also for renovating used properties. Interest in purchasing used homes for renovation and revitalization is also increasing. Here, we explain the typical reasons for renovating vacant houses and used properties.

Reason 1 To Live Comfortably as Your Own Home

The most common reason for purchasing and renovating a used property is “to live comfortably.” Older homes often have issues with the roof, exterior walls, and plumbing, making them less livable as they are. By renovating and updating the facilities and interiors, you can create a comfortable living environment. Additionally, by changing the layout and refreshing the interior, you can achieve a home that suits your family’s lifestyle while keeping costs lower than new construction.

Reason 2 To Increase Asset Value for Sale

More people are purchasing and renovating used properties with the intention of selling them. Used homes are often valued low in their current state, but renovations can enhance their appearance and performance, increasing their value as properties.

Reason 3 To Utilize as Investment or Business

For purchases made for investment or business purposes, renovations are essential. By transforming properties into stylish rentals or share houses, you can differentiate them from others, and depending on the location and planning, you can also expect improved profitability. Initial costs can be lower than new construction, and depending on the use and conditions, there may also be subsidies or tax incentives available, leading to an increase in the number of people utilizing vacant houses for business.

03Points to Consider When Renovating Vacant Houses and Used Properties

Point 1 Choose a Reliable Construction Company

First and foremost, it is essential to select a contractor that you can trust to handle your renovation with peace of mind. Since used properties have had previous occupants, the internal structure and condition are often not clear until you actually see them. Choose a contractor that can carry out the work thoroughly in line with your preferences, the structure of the house, and the surrounding environment, and also provides aftercare following the construction.

Point 2 Always Check the Condition of the Building

For used properties and vacant houses, it is crucial to confirm which parts have deteriorated and to what extent beforehand. Since the property has been occupied by someone else, internal damage is often not apparent without investigation. Conduct a current condition survey before starting construction to identify any hidden deterioration.

Point 3 Review Earthquake Resistance and Insulation Performance

Particularly important in the renovation of used and vacant houses is the review of earthquake resistance and insulation. The earthquake resistance standards were significantly revised in 1981, and homes built before that may not meet current standards. Furthermore, in 2000, regulations regarding joints and foundations were strengthened, making older buildings more likely to lack earthquake resistance. Check the condition of the building before starting construction and be sure to check earthquake resistance and insulation performance.

Point 4 Check Subsidy Programs and Renovation Tax Deductions

To keep construction costs down, it is important to check for subsidies and renovation tax deductions. Subsidies are provided by the national and local governments, and part of the costs for earthquake retrofitting, energy-saving construction, and barrier-free renovations may be supported. There are tax deductions available for “housing loan tax deductions” when using a housing loan, as well as systems that allow for partial deductions of costs for certain works even with personal funds. These can sometimes be used in combination, so it is essential to check in advance and plan to utilize them strategically for a successful renovation (for the latest information, refer to this subsidy section).

04Cost Estimates for Renovating Vacant Houses and Used Properties

The renovation costs for used properties and vacant houses vary significantly based on the extent of damage and the scope of work. First, please familiarize yourself with the approximate costs by area to serve as a guideline for your financial planning (the table below provides general estimates for typical single-family homes. The interior is based on a room of about 6 tatami mats, and the exterior is based on the indicated scope of work. Actual estimates will be provided after a site survey).

1. Roof and Exterior Walls

2. Interior (Interior Finishing)

3. Water-related Equipment

4. Equipment and Infrastructure

5. Waterproofing and Earthquake Resistance

6. Exterior Works

*The above are general estimates. Costs may vary depending on the presence of scaffolding, the condition, grade, and area of the building. Waterproofing for rooftops and updating plumbing and wiring for the entire house may exceed the above estimates depending on the area and method used. Please confirm the exact costs through a free on-site survey and estimate.

07How to Choose a Renovation Contractor for Used Properties and Vacant Houses in Fussa City

There are many renovation companies that serve Fussa City, and it can be confusing to decide which one to choose. When requesting renovations, be sure to check the following five points.

1. Experience in Renovation Work

Many renovation contractors publish their project achievements on their websites. If a contractor provides detailed explanations of the process with photos, it can help you visualize the outcome after the request, giving you peace of mind. If you’re uncertain, choose a contractor with ample experience.

Google and review sites can also be helpful. It’s important to check the content of low ratings, the company’s responses, and the timing of posts. While Google reviews are useful, do not make your decision based solely on reviews; consider project achievements, estimates, and warranty details for a comprehensive assessment.

2. Check for Warranties and After-Sales Maintenance

When selecting a contractor, be sure to check for warranties. If repairs are needed within the warranty period, they may be done for free. The duration varies by contractor and paint type, but typically ranges from 1 to 10 years (emergency repairs and partial repairs are often not covered). Some contractors also offer after-sales services separate from warranties, so be sure to check that as well.

Kakeru Koumuten Co., Ltd. provides a warranty for all exterior renovations and sealing work. We also conduct aftercare maintenance and send out annual notification DM to ensure annual inspections are possible.

3. Obtain estimates from multiple contractors (at least 3 companies)

When requesting renovations, be sure to obtain estimates from multiple contractors. Even for the same construction work, warranties, after-sales service, and prices can vary significantly. Having multiple estimates makes price negotiations easier.

When comparing estimates, it is important to look at not only the costs but also the “items in the estimate,” “check the undercoating materials, sealing materials, and paint for auxiliary parts,” and “confirm the process” in detail. Lowering the rank of auxiliary parts or skipping processes can reduce costs, so it is essential to not make judgments based solely on price.

4. Confirm whether the company conducts renovations in-house

At Kakeru Koumuten Co., Ltd., we carefully listen to and investigate the existing “condition,” “location,” “base materials,” “desired durability,” and “design” to propose the best plan. While there is nothing inherently wrong with a system where partner companies perform the work, it is important to confirm whether the contracting company understands the construction details and clearly defines the responsibilities for quality control and warranty. If the work is done in-house, it is easier to coordinate with the site, making it quicker to respond in case of any issues.

5. Check if they offer color simulations and perspective drawings

Choosing colors and envisioning the final look can be challenging for both exterior and interior work. With simulations, you can reduce the risk of mistakes like “it turned out differently than I imagined.” Since it is difficult to redo once the work is done, it is advisable to choose a company that can provide flexible simulations.
