[Survey Results Summary]
- 66.0% say it's "acceptable" to live in a property over 40 years old
- The number one anxiety about properties over 40 years old is "low seismic performance"
- The condition for a property over 40 years old to be chosen is "renovated"
66.0% say it's "acceptable" to live in a property over 40 years old
When 500 men and women nationwide were asked, "Is it acceptable to live in a property over 40 years old?", the total number of people who answered "Acceptable (10.8%)" and "Acceptable depending on conditions (55.2%)" reached 66.0%.
It's easy to think that old houses are avoided, but we can see that in reality, many people think "an old house is fine."
However, only 10.8% are "actively" willing, which is quite small compared to those who say "depending on conditions (55.2%)." Depending on the conditions, there are attractive old houses and unattractive old houses.
The number one anxiety about properties over 40 years old is "low seismic performance"
The overwhelming number one anxiety felt about properties over 40 years old is "low seismic performance (46.0%)", accounting for more than 40% of all respondents. This is followed by 2nd place "deterioration of the building itself (29.8%)", 3rd place "deterioration of plumbing (21.2%)", and 4th place "low insulation performance (20.6%)" all over 20%.
Overall, there is great anxiety about low housing performance and deterioration. Since housing performance is constantly evolving, it is natural that many people feel anxious about "seismic resistance" and "insulation" the older it gets.
In addition to the deterioration of the building itself, there were many voices worrying about the deterioration and degradation of plumbing and water systems. It can be read that comfort and safety tend to be anxieties when considering properties over 40 years old.
<1st place: Low seismic performance>
- Because the seismic standards remain the old standards, I am concerned about safety during an earthquake. (Male in his 20s)
- Because there are many earthquakes, my image is "isn't 40 years old too old against earthquakes?" (Female in her 30s)
- The poor seismic performance inevitably bothers me. Even if it is renovated and looks better, I can't help but worry about the seismic resistance. (Male in his 40s)
If a property is over 40 years old, it may not meet the current seismic standards. Because Japan is a country with many earthquakes, a home being weak against earthquakes is a major source of anxiety.
There are also voices saying, "I am anxious because it is difficult for an amateur to judge." Because seismic performance is heavily related to invisible parts, it is clear that the point of "not knowing if it is truly safe" also strengthens the anxiety.
<2nd place: Deterioration of the building itself>
- Because I want to live there for a long time, it will be a problem if the deterioration is severe here and there. (Female in her 20s)
- I feel anxiety and resistance when floors and pillars are damaged. (Female in her 30s)
- As the building gets older, there will inevitably be many places that break down, and life will involve making various repairs, so there are more inconveniences compared to newly built houses. (Male in his 50s)
With properties over 40 years old, anxiety about the aging of the entire building also increases. This is because if the deterioration is severe, it leads to the anxiety of "I want to live there for a long time, but I might not be able to."
Deterioration also causes anxiety about vulnerability during disasters, and trying to deal with deterioration costs money and effort. In a deteriorating house, there is a disadvantage that the premise of continuing to live with peace of mind is easily shaken.
<3rd place: Deterioration of plumbing>
