Hello Emma and thanks for your question.
Typically, whenever new homes are sold, the developer's corporate representative (the one with the power to execute documents of this type) will sign the documents in advance of the actual closing. The reason, of course, is that the authorized person may be trying to close more than one home on the same day and at more than one community. Having the documents signed in advance by the sellers ensures that you, as the buyer, are not held up in closing on your home.
In almost all states, the developer will wait until the deed is recorded (when you truly own your home) before providing you with the keys. Prior to your closing (probably just a week prior), however, you should have completed a walkthrough of the unit to approve the interiors, upgrades, conditions, and to create a list of defects to be addressed by the developer. During this walkthrough, the developer will typically tell you when you will be given a set of keys to the home. On the day of "key turnover", the developer will walk through the home again to begin crossing off any items listed on your defects list from the previous walk. Most developers strive to address all of the defects prior to your moving into the home.
If you purchased this home without a Realtor present to assist you, contact the sales office to determine when you can meet and complete the final walkthrough and key turnover. If you are working with a Realtor, the Realtor should advise you of the procedures to obtain keys and claim your new home.
Good luck!!
