I buy a house. How long can I check in normally after I check in?

You can move in as soon as you finish your account, which means that the owner of the house has changed to you. If it is a second-hand house, you can check in on the same day.

If it is an auction house or a new house, if the developer fails to deliver it, you need to wait for the developer to deliver it before you can decorate it. But the ownership of the house is already yours.
