What moves the number
The market sets the number: recent closed sales of genuinely comparable homes, adjusted point by point for condition, lot, and location. If no truly comparable sale exists, the price is built from the closest comparables with documented adjustments, which is exactly the reasoning a court file needs to support.
Condition is the variable most heirs underestimate. Deferred maintenance discounts the price dollar for dollar, and a cluttered home photographs smaller than it is. A clean, decluttered house shows better, photographs bigger, and tends to draw more offers; for an estate, presentability is often the cheapest improvement that moves the final number.
Vacancy matters too. A house that looks lived-in, even when nobody lives there, sells to a larger pool of buyers. And the buyer pool is the quiet driver of the outcome: more eyes on the listing means more offers, and more offers means the estate negotiates from strength instead of desperation.
The "90 percent rule," stated accurately
Under Probate Code 10309, the court must not confirm a sale of estate real property unless the sale price is at least 90 percent of the appraised value, subject to the statute's own exceptions. This is why the phrase "an estate sale must clear 90 percent of appraised value" is true for certain court-confirmed sales, which means sales that must be reported to the court and confirmed by a judge.
It is not a blanket rule for every probate sale. Sales conducted under the Independent Administration of Estates Act (IAEA), where the personal representative has full authority to sell without court confirmation, are not generally subject to the 90 percent confirmation rule. An IAEA sale is priced and negotiated like any well-run sale, with the market and the condition of the property driving the number.
So when an agent says "we have to hit 90 percent of the appraisal," the accurate question is which sale process applies: if the sale must be court-confirmed, the confirmation rule is real; if the estate holds full IAEA authority, the 90 percent figure is not the constraint that governs the sale.
The tax angle: a note, with the caveat
Pricing also interacts with taxes. Inherited property generally takes a stepped-up cost basis, so selling near the date-of-death value often means little or no taxable capital gain. Timing that pulls a sale far from the date of death can change that picture. The step-up guide in this library explains the rule; the numbers for a specific estate belong to a tax professional, so confirm the figures for your dates, ownership, and situation before any decision is made.
