The Buyers Agent completes several action phases on behalf of the Buyer to reach final settlement of any property. They include the preparation phase, sales offer phase, sales processing phase, managing and monitoring the contingency and mortgage phases, the mortgage process, preparation for settlement phase and then final settlement. 

Now that you are actively looking at properties and going on showing appointments with your agent, you should expect them to be performing the following tasks on your behalf

It is imperative that you keep in close communication with your lender who will let you know when additional documents are needed to approve your loan application and fund your loan

The final walk-through usually takes place a day before, or the day of the Settlement.
