Do you tell them there is an unpleasant odor in their house, and you're not sure what it is. But it isn't good. Let's find out what it is, and get rid of it before we list.
Do you tell them the hardware on the cabinetry gives the kitchen an outdated look, and for a few hundred dollars or less they could update the room?
Do you tell them the colors on the walls need to be changed. Neutral earthy tones will completely change the look and feel of the room.
Do you tell them where they need to be priced to sell?
Sellers are looking for guidance. They do not know what color their walls should be, or that they can get an updated look for as little as a few hundred dollars, or where they need to be priced to sell in this market.
Be brutally honest with your Sellers, because they are counting on you.
