When the market moves quickly, your next purchase and your sale need to behave like a team.
If you are trying to buy your next home before selling the current one, timing matters more than bravado. My short answer is that Atherton, CA gives sellers real leverage right now, but that same speed can make the purchase side unforgiving, so I would treat the two decisions as one coordinated move, not two separate adventures.
A typical sale in Atherton, CA took 6 days over the previous 30 days, supply stood at 1.57 months, and recent offers landed at 103.3% of asking. At the same time, the typical asking price for active homes was $12,922,500, while the typical closed price was $14,800,000, so the market is not exactly handing out leisurely decision windows and complimentary second chances.
That matters if you need your sale proceeds to power the next purchase. I would not assume your current home will linger, and I also would not assume the replacement home waits politely while you get organized, because over the last 3 months there were 10 new listings and 6 homes went pending, with pending homes reaching contract after a typical 17 days. That is quick enough to reward preparation and punish improv comedy.
I would map your sale timeline first and build the buying plan around it. I would identify the likely competition before listing, then prepare disclosures, pricing, and showing readiness so your launch does not waste the strongest window. On the purchase side, I would narrow your targets early and be ready to move when the right fit appears. No wandering. Wandering is expensive.
