You should take advantage of the final walk thru provision of the contract just prior to closing.  This provision protects the buyer in case there has been some change in the condition of the property. 

The “closing” is nothing more than finalizing the transaction and exchanging funds.  All of the terms of the contract have been met, all inspections negotiated, the loan documents are signed and funds are provided by the lender and the buyer.

If you have a home that you are selling then you will close that transaction first in order to provide the funds for the purchase transaction. 

If all of the proper documentation and negotiation was completed as provided in the sale contract this should be simply signing documents.
