San Marino Inventory Jumps 27% in One Week, but Asking Prices Hold Steady
· City Deep Dive
San Marino active listings nearly doubled week-over-week. Buyers face tighter competition despite stable prices.
San Marino is one of Southern California's most exclusive communities, and this week's market data shows a meaningful shift in inventory dynamics that deserves close attention from serious buyers. As of September 28, 2026, the city has 64 active listings in our MLS feed, up sharply from 51 just one day prior. That is a 27% jump in available homes in a single week, a volume change that will immediately affect how you approach a purchase here. For context, the overall region we serve (5,267 active listings across 18 cities) saw a median list price of $1,030,000, but San Marino sits in a different category entirely. This is not a market where inventory swings typically occur: when they do, they carry real meaning.
The critical counterpoint is that asking prices have not moved. The median list price in San Marino remains steady, which on the surface sounds favorable to buyers. However, this pairing, more homes on the market but no downward price adjustment, tells a specific story. Sellers are not yet conceding ground on value, even as choice has expanded. This is what happens in markets where confidence remains high and supply was genuinely constrained before. Buyers who were waiting for a price correction should understand that rising inventory alone does not guarantee falling prices; it simply opens the door to more negotiation room and a longer timeline to make a careful decision. You now have more homes to view, but you are not seeing a signal that owners are rushing to liquidate at lower prices.
To understand what this means in practice, consider the buyer's position. With more homes available, you are less likely to feel pressured into a rushed offer on the first property you see. You can afford to be selective, to view multiple homes, and to take time on inspections and due diligence. That breathing room is valuable in a community like San Marino, where homes are large, expensive, and often complex. At the same time, the fact that prices have held steady means that the market has not shifted dramatically in a buyer's favor, you are not seeing a 10% or 20% markdown on asking prices. What you are seeing is the chance to shop more carefully at roughly the same price point, which is its own kind of advantage. Sellers may be somewhat less willing to negotiate aggressively when multiple alternatives exist down the street, but they are not panicked.
For foreign buyers or those relocating from overseas, this inventory moment also means you have time to work with a lender and arrange financing properly. Foreign-national buyers (those without a green card or U.S. status) can borrow with a minimum 30% down payment on a passport basis, with no U.S. credit history, Social Security number, or ITIN required. With six or seven homes in San Marino now available instead of three or four, you are not competing against fifteen other offers for a single house. This creates space to get your documents in order, to arrange international wire transfers if needed, and to understand the escrow and closing process, which typically runs about 30-45 days with financing. That is not a luxury to take for granted in a community this exclusive.
One important reminder: the figures above are from our own MLS feed and represent the homes our team has visibility into as of this moment. To see the complete breakdown of all active listings in San Marino, their exact locations, asking prices, and days on market, visit tuhaousa.com/zh/city/san-marino (in Chinese) or the English version. That full listing table will show you where inventory has concentrated, whether new supply is coming from one neighborhood, one price band, or spread evenly across the community. Distribution matters. A jump of 13 homes means nothing if they are all townhouses or all priced at the low end; it means everything if they span the full range of what you are looking for.
Property tax in California typically runs about 1.1–1.25% of assessed value annually (Prop 13 base rate is 1% of assessed value). For a San Marino buyer, this is a meaningful line item. Suppose a $2,400,000 purchase: property tax at roughly 1.2% of assessed value comes to approximately $28,800 per year, or $2,400 per month. Add homeowners insurance, mello-roos or community assessments if they apply, and your housing costs grow quickly. This is why understanding the property in detail, including any special assessments, HOA obligations, or deed restrictions, matters even more when you have inventory to choose from. Escrow and other closing costs typically run about 2–5% of the purchase price; for a $2.4 million home, that is $48,000 to $120,000 out of pocket. Walk through those numbers with a professional before you commit.
The bottom line for buyers right now: San Marino has given you more choices at the same price level. That is not a crash, but it is a reset. Use the time and the selection to make a careful, informed decision. Do not assume that more inventory will lead to sharp price cuts, it has not yet. And do not assume that you are in a buyer's market just because choice has expanded; in San Marino, supply was simply constrained before, and now it is less constrained. That is the real story.
