On the Peninsula, days on market often measures the listing calendar before it measures demand.
Every listing page shows the number, and most buyers read it the same way: how long has this house been sitting? Useful question. But here, especially in the first couple of weeks, it can mislead.
The number is partly scheduled
Before a Peninsula home goes live, it may already have been shown privately — through the listing agent’s network, internal team previews, or select buyer agents.
Then it hits the MLS. That’s when the public marketing window begins: open houses, showings, disclosures, and usually an offer date several days later.
So when a San Carlos home shows 10 or 13 days on market, that doesn’t mean buyers needed that long to decide. Part of the number reflects a launch calendar designed in advance. And Day 1 on the MLS may not be the first day serious buyers or agents have seen it.
Where the number starts talking
I pay much closer attention once the offer date passes.
A home that goes into contract on schedule tells me the launch worked. But if it’s still active several days later, that’s new information.
Maybe the price was too ambitious. Maybe buyers didn’t respond to the condition, layout, or location. Maybe seller expectations didn’t match the market. Whatever the reason, we know something we didn’t know before the deadline.
Same days-on-market number. Very different story underneath.
For buyers
Before the offer date, speed isn’t necessarily your advantage. You can’t outrun a deadline the seller already set. Preparation matters more:
- Knowing about the home early.
- Understanding the comps.
- Reviewing disclosures.
- Having financing and offer strategy ready.
After the offer date passes without a sale, the conversation changes. You now have market feedback — and potentially more negotiating leverage than the listing page suggests.
For sellers
The first stretch of days on market is partly built into your launch plan. So before listing, I wouldn’t just ask how do we sell quickly? I’d ask: what is our plan if the offer date comes and we don’t get the result we expected?
A seller can lose valuable time by holding the same price after the first buyer pool has already seen the home and responded. Decide beforehand what would trigger a change in price, presentation, or strategy — not on day 19.
What I actually look at
Days on market is one data point. I also want to know:
- Was there an offer date?
- Did it move?
- What happened afterward?
- Were there price changes?
- Was the property marketed or listed before?
Because the more useful question often isn’t how many days has this house been on the market? It’s where is this house in its selling cycle?
Send me the address
I live on the Peninsula and watch these offer dates every week. If there’s a property you’re weighing, send me the address. I’ll tell you what the timing and listing history actually say.
