When I move into a new house, should I leave my keys in the house?

When a new house moves in, there is no need for the property to give the master key to the real estate industry, and you will not leave the key to the property:

It's just that some properties need to be rented if they don't live by themselves. If the property is rented, you can leave the key to the property management, which is convenient for renting a house. But this is usually left by the decoration key.
