Buyers are more comfortable with a probate sale when court confirmation is not required. The process is closer to a traditional sale because the accepted offer does not have to go through a separate court hearing.
With limited authority, the court confirmation process can create uncertainty. Another buyer can appear at the hearing, know the accepted offer price, and try to overbid the original buyer. That possibility can make some buyers more cautious.
When full authority is in place and the notice process is handled correctly, the sale can feel more predictable for buyers, the estate, and everyone involved.
