Most of the inherited-property problems I get called into could have been prevented with one phone call earlier in the process. An attorney settles the estate beautifully, the trustee is ready to move, and then the real estate piece gets handled last — after a decision has already quietly cost the heirs money. I’ve coordinated probate and trust property sales in San Mateo County for 24 years, and this guide is written for you, the Wills & Trusts attorney: where the real estate timing intersects your work, and how looping in the right agent early protects your client and your reputation.
Stepped-Up Basis: Why the Sale Date Is a Tax Decision
Your clients know about the stepped-up basis, but the heirs often don’t grasp how time-sensitive it is. At the date of death, the property’s basis resets to fair market value. A Peninsula home bought decades ago for $250,000 and worth $2 million at death gets a new basis of $2 million — so a sale near that figure generates little or no taxable gain.
The trap is appreciation after death. On the Peninsula, where single-family medians run near $2.2 million and keep climbing, a home that sits for a year while the estate sorts itself out can rack up six figures of new gain — taxed in California as ordinary income up to 13.3%. I’ve watched a family pay roughly $180,000 they never needed to, simply because nobody timed the sale against the basis.
Here’s how I help: The moment you bring me in, I arrange a date-of-death valuation and a current market read so you and the trustee can see the basis, the gain exposure, and the cost of waiting — in dollars — before anyone commits to a timeline.
Trust Sale vs. Probate: Two Very Different Clocks
You handle this distinction daily, but it drives every real estate decision downstream. A trust sale can close in as little as two to six months because no court confirmation is required. A standard probate sale typically runs 12 to 18 months with mandatory creditor periods and, often, court confirmation and overbid procedures.
That difference changes how I prepare and market a property. A court-confirmed probate sale needs pricing and disclosure built around the overbid process; a trust sale lets the trustee move on a cleaner, faster timeline. When I know which track we’re on from day one, I can sequence prep, listing, and offer strategy to match — instead of redoing it midstream.
The Coordination Sequence That Protects Everyone
Here’s the order of operations I run with attorneys and trustees in San Mateo County. Start the real estate conversation 60 to 90 days before listing — not at the closing table. That window lets us secure the date-of-death appraisal, assess condition and any deferred maintenance, decide whether light prep will return more than it costs, and align the sale date with the estate’s tax and settlement realities. Rushing any one of those steps is exactly where money leaks out.
Here’s how I help: I act as the single point of coordination between you, the trustee, the appraiser, and the title company, so nothing falls between roles. You stay focused on the legal work; I keep the property and the timeline moving in lockstep with it. If it’s useful for your practice, I keep a free attorney coordination checklist — the exact sequence I run — that you’re welcome to request here, or read related notes on The Mark Tauber Blog.
Frequently Asked Questions
Q: How does stepped-up basis work when selling an inherited home in California?
The basis resets to fair market value at the date of death, so selling near that value creates little taxable gain. The risk is post-death appreciation, which is fully taxable — making sale timing a genuine tax decision on the Peninsula.
Q: How long does a probate sale take versus a trust sale in California?
A trust sale can close in roughly two to six months; a standard probate sale often runs 12 to 18 months due to creditor periods and court confirmation. The track dictates pricing and marketing strategy.
Q: When should a trustee sell an inherited Peninsula home?
Generally as soon as the estate and the trustee are practically ready, weighed against the stepped-up basis. The longer an appreciating Peninsula home sits, the more new, taxable gain accrues.
Q: Do you have to go through probate to sell a house held in a trust?
Usually not — property properly held in a trust typically avoids probate, which is exactly why the trust-versus-probate distinction changes the timeline and the strategy so much.
