Good question. So long as escrow for your home has not closed yet, you can submit an updated transfer disclosure statement (tds) with respect to the small leak in the utility room that was rectified without much problems.Simply fill in a new tds, date and sign it and submit it to your real estate agent to be dislcosed to all potential buyers. My experience in selling a home is that it is always best to overdisclose matters with the listed property than not. I would not back date the disclosure. Simply date it when you sign it and state when the problem occured with the utility room.
