The call usually comes a few months after the move. Mom is settled in a community in Newport Beach or Irvine, the house in Costa Mesa or Corona del Mar has been sitting empty since spring, and the family has reached the point where paying property tax, insurance, and a gardener on a home nobody lives in no longer makes sense. What they want to know is the order of operations: who can sign, what the sale does to taxes, and how to handle a house full of forty years of belongings. This is that order, in plain English. It is general education, not legal or tax advice, and every one of these families should have an estate attorney and a CPA on the call.

Who has the authority to sell
Start with title. If the home is in a living trust, the trustee, or the successor trustee if the parent has stepped down or is no longer able to serve, has the authority to sell under the trust's terms. If the home is in the parent's name alone and the parent is competent, the parent signs, and a durable power of attorney can let an adult child handle the paperwork. If the parent is no longer able to make decisions and there is no trust and no power of attorney, the family is looking at a conservatorship through the probate court before anything can be sold, which is slow and expensive. This is the single biggest reason estate attorneys push families to get a trust or a power of attorney in place before a health change, not after. Whatever the structure, the title company will want the documents early, so gather them before the listing, not during escrow.
The capital gains rule that still applies
Families often assume that because Mom moved out, the home is no longer her principal residence and the capital gains exclusion is gone. Usually it is not. Federal law lets a homeowner exclude $250,000 of gain, or $500,000 for a married couple, on the sale of a home they owned and lived in for two of the last five years. And there is a specific rule for exactly this situation: if the homeowner becomes physically or mentally unable to care for themselves and moves into a licensed care facility, the time in that facility counts as time living in the home, as long as they actually lived in the home for at least one year during the five-year window. For a parent who lived in the house for decades and moved to licensed assisted living or memory care last year, the exclusion is typically intact. Two things to confirm with the CPA: that the facility is licensed, and how long the exclusion remains available as the years in care add up.
The other tax fact families should understand before choosing between selling now and holding: if the home passes at death, the heirs generally receive a stepped-up basis to market value, which can eliminate the gain entirely. If it is sold now, the parent's original basis applies, offset by the exclusion. On a long-held coastal home with a large gain, the difference can be significant, and it belongs in the decision alongside the cost of carrying an empty house. I covered step-up in basis in more detail earlier.

The Prop 19 angle most families miss
If the parent is buying rather than renting in the next community, such as a condo in a continuing-care setting or a smaller home near a child, Proposition 19 can carry the old property-tax base to that purchase, since the parent is over 55. The purchase and sale need to fall within two years of each other, and the new home has to be the parent's principal residence. Families rarely think of an assisted-living move as a Prop 19 move, but when there is a purchase involved, the savings can be thousands a year for the rest of the parent's life. The details are in my guide to Prop 19 downsizing in Newport Beach.
The reverse is also worth knowing. If the family decides to keep the house and rent it out, it stops being the parent's principal residence, which can affect both the capital gains exclusion over time and the parent-to-child transfer rules if the plan is to pass it on later. Under Prop 19, a rental transferred to a child is reassessed to market value. Holding is a legitimate choice; it just changes the tax picture, and the family should choose it on purpose.
The empty house
An empty coastal home has three practical problems. Insurance: most homeowners policies limit or exclude coverage once a home has been vacant for 30 to 60 days, so call the carrier and ask about a vacancy endorsement or a vacant-home policy before the gap opens. Security and upkeep: set up regular visits, keep the yard maintained, and leave a few lights on timers, because a visibly empty house draws attention. And contents: the estate sale, donation runs, and the difficult sort through decades of belongings are the part that stalls most families. Give it a date on the calendar and, if the family is scattered, hire an estate-sale company to run it. A home shows better empty and clean than half-packed, and buyers read a lingering listing as a family that has not decided.
A realistic timeline
Documents and authority sorted, one to three weeks. Contents cleared and the home prepared, four to eight weeks depending on how much there is and how much cosmetic work the family chooses to do. On market to accepted offer in coastal OC this fall, typically several weeks for a well-priced home. Escrow, thirty to forty-five days. Call it three to five months from the first family conversation to closing, and shorter when the trust and the paperwork were already in order. The families who feel least rushed are the ones who started the document conversation before the move, which is a good argument for having it now if a parent is still at home.
Questions families ask
Can my parent still use the capital gains exclusion after moving to assisted living?
Usually yes. Federal law treats time in a licensed care facility as time living in the home if the homeowner became unable to care for themselves and lived in the home for at least one year during the five-year lookback. The $250,000 or $500,000 exclusion is typically still available. A CPA should confirm the facility's licensing and the timing.
Who can sign to sell a parent's house after they move to assisted living?
The trustee if the home is in a living trust, the parent if they are competent, or an agent under a durable power of attorney. If the parent cannot make decisions and there is no trust or power of attorney, the family generally needs a court conservatorship before the home can be sold.
Should we sell the family home now or keep it until our parent passes away?
Selling now uses the parent's original basis offset by the capital gains exclusion, while inheriting later generally gives heirs a stepped-up basis to market value. Weigh that against the cost and risk of carrying an empty home, and make the decision with an estate attorney and CPA.
Does Prop 19 apply when a parent moves to assisted living?
If the parent is buying a replacement home, such as a condo in a care community, Prop 19 can transfer the old property-tax base to it because the parent is over 55, as long as the sale and purchase fall within two years of each other and the new home is the parent's principal residence.
A note from Jade
These sales are about a family as much as a house, and the best ones are handled with patience and a clear plan. If your family is at this point, I am glad to coordinate with your parent's attorney and CPA, give you an honest read on the home's value, and take the logistics of an empty house off your plate.

This is general real estate education, not legal or tax advice. Authority to sell, tax exclusions, and Prop 19 eligibility depend on the family's documents and circumstances. Before making a decision, confirm the details with an estate attorney, a CPA, or another qualified advisor.
