Okay, thank you for the opportunity to clarify.
We are not necessarily aiming for 60 years. In terms of our financial analysis, we limit it to 20 years, because it is usually the next 20 years that are the most critical.
There is not necessarily an end date. I don't know if there are any official residences that are more than 100 years old, but it is quite possible that some might be in heritage buildings or buildings that are of a certain age, or at least ten or so years old.
You have to consider the condition of the building. Refurbishing is usually considered at the midpoint of a building's lifespan. We try to determine whether the property can be used until the building is 50 or 60 years old. Then a decision has to be made. Is it better to renovate or replace the property? We might decide to renovate and keep the property. We do not necessarily have a preconceived idea based on the age of the property. We do a cost-benefit analysis, whether it is better to keep it or replace it.
