Some real estate agents ask us whether elderly people can move into an apartment or not. Unfortunately most landlords decline it. Because there is a possibility that tenants die in the apartment. In that case, we need to tell next tenant. Most people usually hesitate to apply for these apartments so landlords need to lower the price of the room which means the value of the apartment decrease. Not only that, some elderlies don't have close relatives. Sometimes, they are found long time after they die with really bad smell. The smell is absorbed into the room and it can be a little difficult to get rid of <strike style="background-color: rgb(255, 255, 0);">it</strike> completely. However a certain company reduces the risk of this situation. They install the sensor which can recognize the tenant's movement. If they don't move, it can call company soon. Though, some landlords accept elderlies, most landlords still hesitate to let them move into the apartment. We are facing the serious problem with aging population. I think we should give the first priority to think about how we accept elderly people.
