After I take the house, I will leave a key in the property. What's going on? When will it be returned? Thank you.

Leaving the key in the property is generally to manage and maintain the house when the owner has not moved in. When a resident moves in, the property management company will return the key to the owner.

If the owner doesn't trust the property, he can refuse to give the property key. At the same time, after the owner moves in, the property company should also return the keys in time.

Please feel free to let me know if you have any other questions or need further help.
