Once you have accepted an offer to sell your house you will need to make a list of all the things you must do, and a list of all the things the buyer must do, in order to proceed successfully to closing. The property may need to be formally appraised, surveyed, inspected or repaired. Depending on the specifics reached during the negotiations, you may pay for all, some, or none of these items. If each procedure returns acceptable results as defined by the contract, then the sale may continue. If there are problems with the property the terms set forth in the contract will dictate your next step. Depending on the contract, you or the buyer may decide to walk away, open a new round of negotiations, or close. 

Your agent can save you time and money by coordinating all the necessary items that must be done to finalize the sale.
