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

Kiyose City in Tokyo is a town in the northern Tama area, adjacent to Tokorozawa City in Saitama Prefecture, characterized by a harmonious blend of zelkova tree-lined streets, farmland, and residential areas. With its history of being a gathering place for sanatoriums, the area is rich in greenery and offers a tranquil living environment.

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

02Reasons for Renovating Vacant Houses and Used Properties

In recent years, the Japanese housing market has expanded options not only for new constructions but also for utilizing renovated used properties. There is a growing interest in living in renovated or refurbished used homes. 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 houses often have issues with the roof, exterior walls, and plumbing, making them difficult to live in as they are. By renovating and upgrading the facilities and interior, you can create a comfortable living environment. Additionally, by changing the layout and refreshing the interior, you can finish your home to suit your family’s lifestyle while keeping costs lower than a new build.

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, thereby increasing their value as properties.

Reason 3 To Utilize as an 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 other properties, and depending on the location and planning, you can expect improved profitability. Initial costs can be lower than for new constructions, and depending on the use and conditions, there may also be subsidies or tax incentives available, leading to an increase in 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 you can trust to handle your renovation. Since used properties have had previous occupants, the internal structure and condition are often not clear until you actually see them. Choose a contractor who can carry out the work thoroughly in accordance with your wishes, the structure of the house, and the surrounding environment, and who also provides aftercare following the construction.

Point 2 Always Check the Deterioration of the Building

For used properties and vacant houses, it is crucial to check which parts are deteriorating and to what extent beforehand. Since the property has been lived in by someone else, internal damage is often not apparent without investigation. Conduct a current condition survey before starting construction to identify 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 houses built before that may not meet current standards. Additionally, 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 the 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. Tax deductions include the “housing loan tax deduction” 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 important to check in advance and use them strategically as a key to successful renovation (for the latest information, see this subsidy section).

04Cost Estimates for Renovating Vacant Houses and Used Properties

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

1. Roof and Exterior Walls

2. Interior (Interior Finishing)

3. Water Facilities

4. Equipment & Infrastructure

5. Waterproofing & 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. Please confirm the exact costs through a free on-site survey and estimate.

07How to Choose a Remodeling Contractor for Used Properties and Vacant Houses in Kiyose City

There are many remodeling companies available in Kiyose City, and it can be confusing to decide which one to choose. When requesting a remodel, be sure to check the following five points.

1. Experience in Remodeling Work

Many remodeling contractors showcase their work on their websites. If a contractor provides detailed explanations of their processes with photos, it can help you visualize the outcome after your 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 the posts. While Google reviews are particularly useful, don’t make your decision based solely on reviews; consider their track record, estimates, and warranty details for a comprehensive evaluation.

2. Check for Warranties and Aftercare Services

When selecting a contractor, be sure to check for the availability of warranties. Repairs may be free within the warranty period. The duration varies by contractor and paint type, but typically ranges from 1 to 10 years (emergency repairs or partial fixes are often not covered). Some contractors also offer aftercare services in addition to warranties, so be sure to check for those 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, making annual inspections 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 work, warranties, aftercare services, and prices can vary significantly. Having multiple estimates makes it easier to negotiate prices.

When comparing estimates, it’s important to look at not just the costs but also the “items in the estimate,” “check the undercoating materials, sealing materials, and paint for auxiliary parts,” and “confirm the process.” Lowering the rank of auxiliary parts or skipping steps can reduce costs, so it’s essential to not make decisions based solely on price.
See detailed points for comparing estimates

4. Confirm whether the company performs renovations in-house

At Kakeru Koumuten Co., Ltd., we conduct detailed hearings and investigations regarding the existing “condition,” “location,” “base materials,” “desired durability,” and “design” to propose the optimal 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 work 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, allowing for quicker responses in case of any issues.

5. Check if they offer color simulations and perspective drawings

Choosing colors and visualizing the image after construction can be challenging for both exterior and interior work. Having simulations 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 accommodate flexible simulations.
