A client called me last month with a screenshot. She had been comparing three Peninsula cities side by side on her phone, the way most buyers do now before they ever call an agent, and one number stopped her cold. Rolling Hills Estates, the city she and her husband had circled as their top choice, showed home prices down 28 percent year over year. Rancho Palos Verdes was basically flat. Palos Verdes Estates looked like it was climbing. Her question was simple: had she picked the wrong hill?
She hadn't. What she'd found wasn't a falling market. It was what happens to a median price when the number of sales behind it gets small enough that any single house can move it.
What Twelve Sales Can Do to a Median
Redfin's own data page for Rolling Hills Estates puts the headline number in plain terms. In March 2026, home prices in the city were down 28.2 percent compared to the year before, with a median sale price of $1.5 million. Average days on market jumped to 126, up from 39 the prior year. And here is the detail that changes the whole reading: only 12 homes sold in Rolling Hills Estates that month, up from just 6 the year before.
Twelve sales is not a market. It's a dozen individual decisions by a dozen individual sellers, and a median built on that few transactions behaves less like a trend line and more like a coin flip. If two or three of those twelve happened to be smaller homes on standard lots rather than the larger equestrian-zoned properties the city is known for, the median drops hard, even if not a single seller in town actually cut their asking price. Nothing about the underlying value of a Rolling Hills Estates home changed. The mix of what happened to close that particular month changed.
You can see the mechanism in a real closing. On January 16, 2026, an equestrian property at 36 Pony Ln, sitting on more than 26,000 square feet with a two-stall barn and direct access to the trail network that laces through the city, sold for $2,633,000. That's the kind of sale that pulls a thin month's median up. Take a sale like that out of the mix, or swap it for two smaller lots closing in the same window, and the reported year-over-year percentage swings by double digits without any change in what buyers are actually willing to pay for comparable homes.
What a Thicker Market Looks Like
Compare that to Rancho Palos Verdes, where Redfin's data for the three months ending May 2026 shows a median sale price of $1.7 million, up 2.0 percent from the same period the year before, with homes selling in around 40 days on average, close to the 38 days recorded the prior year. That city moved 107 homes in May 2026 alone, down from 126 the year before, but still nearly ten times the transaction count Rolling Hills Estates saw in its most recent reported month.
Volume like that doesn't eliminate volatility. The same Redfin page, in its separate rolling monthly summary, puts last month's average price at $1.64 million, down 10.3 percent, a figure that contradicts the steadier three-month median sitting a few lines above it on the same page. Average price gets skewed by a handful of outlier estates even in a market this size. But the three-month median, built on well over a hundred transactions, has enough weight behind it that one unusual sale can't drag the whole number around the way it can in a twelve-sale month. That's the real difference between Rolling Hills Estates and Rancho Palos Verdes. It isn't that one city is falling and the other is stable. It's that one number is trustworthy because of how many sales stand behind it, and the other isn't yet.
Palos Verdes Estates Shows the Same Math From the Other Direction
Palos Verdes Estates makes the point again, just pointed the opposite way. Redfin's three-month window ending May 2026 shows a median sale price of $3.0 million, down 0.73 percent from the year before, essentially flat, with 43 homes sold in May compared to 39 the year before. Days on market rose to 43, up from 32 the prior year, a real signal that homes are taking longer to find buyers even at a roughly stable price point.
But the same page's separate average-price line tells a different story: last month's average house price came in at $2.73 million, up 11.7 percent. A three-month median down less than a point and a one-month average up nearly 12 percent are not describing two different markets. They're describing one market with too few monthly sales for any single snapshot to be fully trusted on its own, the same underlying condition driving the Rolling Hills Estates headline, just landing on the other side of zero this time.
Reading These Numbers Like an Agent Instead of a Portal
None of this means the headline percentages are wrong. Redfin is doing the math correctly. It means the headline percentage answers a narrower question than most buyers assume. It tells you what happened to the specific homes that closed in a specific window. It does not tell you what your specific offer on a specific house will need to look like to win.
| City | Window | Median Sale Price | YoY Change | Days on Market | Homes Sold |
|---|---|---|---|---|---|
| Rolling Hills Estates | March 2026 | $1.5M | -28.2% | 126 (vs. 39 prior year) | 12 (vs. 6 prior year) |
| Rancho Palos Verdes | 3 months ending May 2026 | $1.7M | +2.0% | 40 (vs. 38 prior year) | 107 (May 2026) |
| Palos Verdes Estates | 3 months ending May 2026 | $3.0M | -0.73% | 43 (vs. 32 prior year) | 43 (vs. 39 prior year) |
If you're weighing these three cities against each other, the transaction count next to the price matters more than the price itself. A city moving a dozen homes a month can post a scary or flattering headline in either direction almost by chance. A city moving over a hundred is telling you something closer to the truth about where buyer demand actually sits. Before you let a single percentage push you toward or away from a neighborhood, ask what it's built on. How many sales are in that window. Whether the days-on-market figure is climbing or holding steady, since that tends to move more slowly and more honestly than price. And whether the specific homes you're comparing, not the city average, are actually alike in lot size, condition, and location within the city.
That last part is where a local read matters more than any portal snapshot. Rolling Hills Estates isn't one market. A resale on a standard lot near Peninsula Center behaves differently than an equestrian property backing onto the trail network, and lumping them into one monthly median is exactly how a 28 percent headline gets created out of ordinary variation.
Working With Someone Who Knows Which Twelve Houses Sold
Numbers pulled from a portal can tell you the shape of a market from a distance. They can't tell you why a particular street held its value while the one next to it didn't, or which of last month's twelve closings actually competes with the house you're considering. That's the gap between reading a headline and understanding a market, and it's the gap I spend most of my time closing for clients across Rolling Hills Estates, Rancho Palos Verdes, and Palos Verdes Estates.
If you're comparing these three cities and want the real story behind the numbers on your screen, not just the percentage at the top of the page, I'd welcome the conversation.
