01Reasons for the Increase in Renovations of Used Properties and Vacant Houses in Yugawara Town

Yugawara Town is a historic hot spring area mentioned in the Manyoshu, with many villas and resorts from the coastline of Sagami Bay to the mountains. Located at the westernmost tip of Kanagawa Prefecture, bordering Shizuoka Prefecture, it boasts a warm climate and rich nature.

Old wooden houses and villas along the coast and in the mountains are at a stage where they require seismic, insulation, and salt damage countermeasures, and the demand for relocation, dual residences, and villa regeneration is increasing. This is why the option of “buying a used detached house or villa and renovating (renovating) it to suit your lifestyle” is expanding in Yugawara Town.

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 by purchasing and renovating used houses. 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 roofs, exterior walls, and plumbing, making them difficult to live in 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 interiors, you can finish a home that suits your family’s lifestyle at a lower cost 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 houses are often valued low as they are, but renovations can enhance their appearance and performance, thereby 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 constructions, and depending on the purpose and conditions, there may be subsidies or tax incentives available, leading to an increase in those 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 the renovation. Since used properties have had previous occupants, the internal structure and condition are often not clear until you see them in person. Choose a contractor who can carry out the work thoroughly according to your wishes, the structure of the house, and the surrounding environment, and who 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 lived in by someone else, internal damage is often not apparent without investigation. Conduct a current condition survey before starting work 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. 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 work 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, supporting part of the costs for earthquake retrofitting, energy-saving construction, and barrier-free renovations. Tax deductions include the “housing loan tax deduction” when using a housing loan, and there are systems that allow for deductions on certain costs even with personal funds. These can sometimes be used in combination, so it is essential to check in advance and plan to utilize them effectively 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 significantly based on the degree of deterioration and the scope of work. First, please understand the approximate costs by area to use 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 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 of rooftops and updates to 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 Yugawara Town

There are many renovation companies that cater to Yugawara Town, and it can be confusing to decide which one to choose. When requesting renovations, be sure to check the following 5 points.

1. Experience in Renovation Work is Abundant

Many remodeling contractors publish their construction achievements on their websites. If a contractor provides detailed explanations of the process with photos, it makes it easier to visualize what to expect after hiring them, which brings peace of mind. If you have concerns, choose a contractor with ample experience.

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

2. Confirm the presence of warranties and aftercare services

When choosing a contractor, make 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 aftercare services in addition to warranties, so be sure to check that as well.

Kakeru Koumuten Co., Ltd. provides warranties for exterior remodeling and sealing work. We also conduct aftercare services and send out annual reminder DM, making annual inspections possible.

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

When requesting remodeling, be sure to obtain estimates from multiple contractors. Even for the same construction content, warranties, aftercare services, and costs can vary significantly. Having multiple estimates makes price negotiations easier.

When comparing estimates, look at not just the costs but also the “items in the estimate,” “check the undercoat 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 important not to judge solely based on price.

4. Confirm whether they perform remodeling in-house

Kakeru Koumuten Co., Ltd. conducts detailed hearings and surveys on the existing “condition,” “location,” “materials,” “desired durability,” and “design,” to propose the optimal plan. While there is no inherent problem with the system where partner companies carry out the construction, it is important to confirm whether the contracted company understands the construction details and clearly defines the responsibilities for quality control and guarantees. If the construction is done in-house, it becomes easier to coordinate with the site, allowing for quick responses in case of any troubles.

5. Do they offer color simulations and perspective drawings?

Choosing colors and envisioning the outcome after construction can be challenging for both exterior and interior projects. 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 construction is done, it is recommended to choose a company that can provide flexible simulations.
