Usually, yes. A personal representative with issued, unrevoked letters can generally sell estate property without a separate court order. Follow any restriction on a sale in the will, and a beneficiary specifically left the house generally must join in the sale. A court-order exception may apply when the estate cannot otherwise pay its required expenses and claims. A valid transfer-on-death designation may pass the house outside probate. Have the deed, will, appointment papers, and any court orders checked before setting a closing date.
