“What you want to do”, she said to the seller, “is remove anything that might get between the buyers and their ability to want to, and be able to picture themselves in your house”.
What are some of those roadblocks?
Price is one. Until they are no longer worried that they may be paying more than it is worth its an obstacle. Needed repairs that are obvious is another (think roof, siding, water stains in the basement, etc). Clutter is another problem that will make is difficult to picture themselves in the space as are personal photos.
This advice isn’t new but is is a new way of looking at it. Elegant.
