What probate means for home sales in King County

Unless it was held in a trust or with survivorship rights, a Washington home owned by someone who has died usually passes through probate.

An executor or administrator, also called a personal representative, is appointed by the court, handles the estate’s debts, and can usually sell the home. Ask the estate’s attorney which steps apply before you put in an offer, because some sales need court approval.

Usually the choices are to keep the home, rent it, or sell it. When there are several heirs, the estate needs cash to pay bills, or the house needs major work, selling is a common choice.

Avoidable mistakes with King County probate leads

In King County, the most common mistake is negotiating with the wrong person. In most cases, the personal representative, or another person with legal authority, is the only one who can sign an estate contract, so check who has that authority before you make an offer.

In King County, overpaying or holding a property too long is another way investors lose money. Before you make an offer, review recent sales, permit timelines, and realistic repair costs, and decide on your exit before you buy.
