Sandy Kantor, a top real estate agent in Tucson, Arizona, was helping a senior couple sell their home filled to the brim with clutter and paperwork when crisis struck. “The wife was feeling overwhelmed to begin with and was trying to figure out how she was going to get through all of this, and a week after we signed the listing agreement, her husband had a heart attack,” recalls Kantor, JD, SRES, CRS.
