01Reasons for the Increase in Renovations of Used Properties and Vacant Houses in Tsuzuki-ku

Tsuzuki-ku, Yokohama City, is one of the newest wards in Yokohama, established in 1994, and was planned around Kohoku New Town. Centered around Center Kita and Center Minami, it features residential areas with single-family homes and abundant greenways and parks, making it a popular area especially among families with children.

On the other hand, homes sold in the early stages of the new town are now entering a generation change period of over 30 to 40 years. This is why the option of “buying a used single-family home and renovating it to fit our lifestyle” is expanding in Tsuzuki-ku.

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 renovating and utilizing used properties. There is 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 homes often have issues with the roof, exterior walls, and plumbing, making them uncomfortable to live in as they are. By renovating and upgrading the facilities and interiors, 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 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 tend to be valued low as they are, but renovations can enhance their appearance and performance, increasing their value as properties.

Reason 3 To Utilize as an Investment or Business

When purchasing 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 also expect an increase in profitability. Compared to new constructions, initial costs can be reduced, and depending on the use and conditions, there may be cases where you can qualify for subsidies and tax incentives, leading to an increase in the number of people utilizing vacant houses for business.

03Points to Consider When Renovating Vacant or 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 renovations. 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 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 Deterioration of the Building

For used properties and vacant houses, it is crucial to check 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 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 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.

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, and there are systems where part of the costs can be deducted for certain works even with personal funds. These can sometimes be used in combination, so it is crucial 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 and Used Properties

The renovation costs for used properties and vacant houses vary significantly depending on the degree of damage 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 one 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 Facilities

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 updates to plumbing and wiring for the entire house may exceed the above estimates depending on area and method. 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 Tsuzuki Ward

There are many renovation companies that serve Tsuzuki Ward, Yokohama, 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

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 and provide peace of mind. If you’re feeling 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. In particular, Google reviews are useful, but don’t 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 choosing 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, so be sure to check for those as well.

Kakeru Koumuten provides warranties for exterior renovations and sealing work. We also conduct after-sales maintenance, sending 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 scope of work, warranties, after-sales service, and costs can vary significantly. Having multiple estimates makes it easier to negotiate prices.

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, we conduct detailed hearings and investigations regarding the existing “condition,” “location,” “base materials,” “desired durability,” and “design,” to propose the most suitable 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 scope of work and has clear responsibilities for quality control and warranties. If the work is done in-house, it is easier to coordinate with the site, allowing for quick 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 provide flexible simulations.

We are also equipped with various tools to handle different types of construction, such as compressors and cleaning machines.

In-House Waste Sorting

In exterior renovations, various waste materials such as paint, wood, and metal are generated. While many contractors dispose of them all together, our company significantly reduces waste disposal costs by sorting and recycling waste materials.

Exterior Renovation Dedicated Showroom

In our showroom, you can not only have meetings but also check the actual paint colors and a wide range of catalogs. You can also confirm heat insulation properties using color simulations and heat insulation paint testing equipment. It is just a 3-minute walk from Eda Station, which is close to Tsuzuki Ward.

To improve skills, we create various models and conduct practical training. Since exterior renovations differ in construction methods and materials based on existing materials and shapes, we regularly conduct technical improvement training to ensure each staff member can handle various sites.
