Independent administration sells like an owner would
A usufruct means two sets of signatures
When a surviving spouse holds a usufruct over the house — the right to use it and collect any rent, without owning it outright — the children typically hold the "naked ownership" underneath. Conveying full marketable title generally takes signatures from both the usufructuary and the naked owners, since neither alone can deliver the whole interest a buyer expects.
Forced heirship can't be waved away by the will
Children under 24, or permanently incapacitated children of any age, are forced heirs under Louisiana's civil code, entitled to a guaranteed minimum share of the estate — the "legitime" — regardless of what the will says. Their claim has to be resolved as part of clearing title, not simply overridden.
No state estate or inheritance tax
Louisiana imposes neither. See Capital Gains Tax on the Sale for the separate income-tax question on the gain itself.
Title companies still want the paperwork on record
Even in an independent administration, a title company generally wants a recorded Judgment of Possession, or a qualifying recorded small succession affidavit, before it will insure the transfer — the representative's broad authority to sell doesn't skip that recording step.
