If you want to buy a Silicon Valley home and you’re coming from outside of the area, you will likely notice that a few things are done differently here. Rather than give a lengthy explanation, I’ll just provide a quick list of some of the ways in which our market practices are different from other parts of California, the U.S. or around the world.
10 Home Buying and Selling Practices in Silicon Valley that Might Surprise You
1.) The escrow account, where money is held and disbursed by a neutral third party, is ordinarily with a title company in Silicon Valley and the San Francisco Bay Area generally. In CA it’s legal for real estate brokers to have the escrow account, but that is not the custom here. By contrast, in southern Calif., there are separate companies which often do the escrow work or a real estate broker may handle the funds, called trust funds.
2.) Santa Clara County is a “seller pay county” by tradition when it comes to the escrow fee and who pays the owner’s policy of title insurance. (Most of California is either buyer pay or split 50/50. Also, Santa Clara County is where San Jose and the bulk of Silicon Valley is located.)
3.) Because it’s a “seller pay” county, the seller or the listing agent (the seller’s real estate agent) typically chooses the title company. Most of the time, the home owners do not have a preference and don’t know anyone working at the nearby title companies, so usually the listing agent suggests one which they have had good experience with. But not everything paid in escrow is paid by the seller. For instance, if you purchase the property with a loan, you will need to buy lender’s insurance, too – and that’s a buyer cost.
4.) While in many east coast states an attorney is involved with the home buying and selling process, here lawyers are seldom involved with real estate sales – unless there is a big problem.
5.) Surveys are not usually part of the transaction here, with exceptions if there are serious doubts about the property boundaries.
6.) Buyers are provided information on natural hazards, and usually also known environmental hazards and area tax liabilities, in most cases via a professional disclosure company such as JCP Disclosures. Things such as 100 year flood plains, liquifaction zones, earthquake fault lines, underground water contamination will be revealed, if known, in most cases.
7.) Most sellers provide inspection reports upfront. Most sellers get inspections prior to listing and provide these to buyers upfront with their disclosure packet. That also means it’s less common to see offers with contingencies in our market (at least not inspection contingencies). Pest and property inspections are expected by Silicon Valley buyers, as are roof inspections unless it is a condo or has a very new roof. Additional inspections may also be provided based on additional property features, or worrisome defects (i.e. a pool inspection for a home with a pool, a well inspection for homes on well water, or if there is a large crack in the fireplace then a chimney inspection might be done).
8.) In some parts of the world, buyers do not have their own real estate professionals for guidance and advocacy, but here they do. Most of the time, in the San Jose and Peninsula area buyers have their own real estate agent working on their behalf, just as sellers have their own agent. Usually the buyers’ agents are paid by the sellers (a term that’s negotiated in the purchase contract), but they do not represent the sellers.
Note: Dual agency is legal in California as long as it is disclosed (and dual agency can mean either the same person or brokerage). Also, purchasing a home as an unrepresented buyer (no professional working on their behalf), is legal, but uncommon and generally not advisable.
9.) It has become the norm to get pre-approved with a lender or bank prior to writing a purchase offer on a house, condo or other home. (If you meet with a Realtor, getting you set up with a reputable lender will be one of the first things he or she asks you to do.) Also buyers have to provide “proof of funds” to demonstrate that they have the down payment available. Sometimes our international clients are surprised at the documentation required here, so it’s good if you are aware of it upfront.
Finally, it should be noted that the cost of housing in Silicon Valley is truly exorbitant. Most people know that Silicon Valley houses are very expensive, but until they get out and see what things cost, they really don’t understand how extreme it is. Often I tell people to expect to pay twice as much and to get half as much. Unless you are coming from a pricey locale, such as London, Tokyo, Paris, Manhattan or Boston, you may still find yourself in “sticker shock.”
One and a half million dollars buys a fairly small, modest home here, in an average area. Two million dollars is better – you can get into a better area and better house. The “luxury market” starts somewhere between $3.5 and $4.5 million, depending on which area you’re considering.
There are pros and cons to the way the market works here compared to other areas, but going in prepared and knowing what to expect will help you find a great home and have a smooth purchase as you relocate to Silicon Valley!
Today we’ll provide a few quick graphics to give you a Silicon Valley pricing snapshot on the counties where we sell homes. These will be ranked by the usual order of housing cost, from highest to lowest. (Sometimes they move “out of order”.) After that, we’ll provide more resources from our other sites and blogs with a deeper dive on our main Silicon Valley real estate markets.
Please note that we don’t cover all 9 of the San Francisco Bay Area counties, but here you’ll find several of them covered, plus Santa Cruz County (“central coast” and still Silicon Valley) and it’s a pretty good primer on the Bay Area housing market analysis.
Silicon Valley Pricing Snapshots
San Mateo County
San Mateo County is “The Peninsula”, the county just south of San Francisco and north of Santa Clara County and Santa Cruz County, touching the Bay on one side and the Pacific on the other. About a quarter of Silicon Valley is in this area, generally. It’s normally more expensive than Santa Clara County, but once in awhile those two areas flip for pricing order. It’s a hot market in San Mateo County!
Santa Clara County
Santa Clara County, our home base, normally is the second priciest area in this region and is the heart of Silicon Valley:
Today we’ll share the market reports for three Silicon Valley Counties. These are from July 2025.
Santa Clara County, San Mateo County, and Santa Cruz County are the areas covered below. Generally, “Silicon Valley” is 95% within Santa Clara and San Mateo Counties, plus a little of Santa Cruz County and a small part of Alameda County. Alameda County uses a different MLS system, and we don’t usually sell there, so we are not covering it in this post.
Each section below includes first the data for single family homes and then condos and townhomes for each region.
If you’re ready to dive a little deeper, we also provide regular monthly market updates on some of the popular communities within Santa Clara County over at my Valley of Heart’s Delight blog. Scroll the most recent ones here.
July 2025: Three Silicon Valley Counties
Santa Clara County Real Estate Market Report for July 2025
The first of the three Silicon Valley counties is Santa Clara County – home to San Jose, Cupertino, Sunnyvale, Mountain View, Palo Alto, Los Altos, Santa Clara, Campbell, Los Gatos, Saratoga, Monte Sereno, Milpitas, Morgan Hill, and a number of other cities and towns. This county is the heart of Silicon Valley.

The market is clearly cooling with longer days on market, fewer sales, and a falling sales price.
The condominium and townhouse report for Santa Clara County
While it had fewer than half the sales of the single family home market, the condo and townhouse market is experiencing similar trends, though prices are on the rise again after an earlier summer low.
Keep reading for updates on the San Mateo and Santa Cruz county markets.
If you’re relocating to the San Jose area, there are a few tools you can use for resources as you evaluate different parts of the region. When I started this website, I had books listed that you could purchase. Today, mostly I have websites that you should bookmark – for free!
Map data: Cal My Hazards
Natural & Environmental Hazard Information Tools You Can Use
Natural hazards are found throughout the United States, often the major one people consider is the one hundred year flood plain. Here in the Golden State, we have some additional concerns relating to fire and earthquake risks.
California MyHazards can display a map anywhere in the state with information relating to liquefaction zones, earthquake faults, 100 year flood plains, and high fire risk areas. (The info for the very high fire hazard severity zone has not been updated, so use the Cal Fire map for that info.)
Flooding from Dam Failure (potentially caused by earthquakes as well as other possibilities) is scary. Learn more about those zones at the link I’m providing here. (As of this writing, the Approved Inundation Maps link is not working.)
A Barclay’s Locaide will outline earthquake faults, flood plains, and other natural hazard zones you might want to know about. This is now out of date, but you may be able to locate a used one online or see if a local real estate association of Realtors bookstore has it available.
Something else to know is that there are state mapped earthquake faults (the more active ones, such as the Hayward or San Andreas Fault) and also the city, town or county mapped fault zones (for example, the Shannon Fault). The latter may have been dormant for 11,000 years or more.
Buying a home? Sellers usually provide a Natural Hazard Report, an Environmental Hazard Report, and a Tax Report from a company such as JCP. This same company / site has a great amount of information on local conditions on its About the Hazards page that newcomers would benefit from.
When buying a home in California, consumers are given a link to download brochures, or one combined document, on a variety of hazards. I’m not sure that most of them take the time to read it, but it’s excellent info and I highly encourage anyone living in CA, whether renting or owning, to read it: Homeowner’s Guide to Earthquake Safety & Environmental Hazards
Environmental Hazard Zones: Research Tools You Can Use
Local concerns also include environmental ones, such as Superfund sites.
Envirostor is an excellent resource for seeing Superfund and other toxic sites
Some sites with spills, leaking underground storage tanks, or other issues can be found at this Cleanups in my community page (nationwide info)
Mercury, or quicksilver, was mined in Almaden (New Almaden and related mines) and east Los Gatos (Guadalupe Mine area) – it is a naturally occurring element in cinnabar. For that reason, creeks in those areas should not be entered or fished in. It can be found in other creeks and rivers, too, but primarily in Almaden.
Asbestos is another naturally occurring element here. It was prized for being somewhat fire resistant and was mined under Communications Hill. It’s something to investigate if you want to live in that area.
Oil, gold silver, and other elements were mined here as well as granite (we still have quarries active in Santa Clara County today, a couple in the Cupertino area and one in the hills by Lexington Reservoir just outside of Los Gatos). Some old mines are not mapped if they are on private land, so one of the disclosures we have relates to unmapped, abandoned mines., which may be found in more rural pockets of the county.
Flooding from dam failure (dams are human made, hence it’s not a “natural” hazard ) is a risk in a large part of Silicon Valley. Most of the areas at risk from flooding due to dam failure are listed on this site.
In addition to natural and environmental hazards, there are big plusses that will attract new residents.
A School District Map of the County with school district boundaries will be a big help to you here, as schools are the #1 thing that drive home values. You can buy one at bookstores or online for about $5
If you want to read about individual communities within Santa Clara, I have an over view in popehandy.com (covers a broad area) and do market updates on many areas within SanJoseRealEstateLosGatosHomes.com (my main blog)
It is also helpful to have a knowledgeable Realtor as your resource! Please call me if you’d like assistance in your move to SIlicon Valley. I’d be happy to help you.
Santa Clara County is home to a number of Superfund sites. Where are they?
A helpful, free website that anyone can use is EnviroStor. From the home page you can take a tour on how to learn about Superfund and other environmental hazards in California. The image below is showing only the Federal Superfund – please note in the left column that just the first box is checked. If you are particularly interested in school cleanup or school investigation, you’ll want to check those boxes. (The image is linked to the EnviroStore page fyi.)
Map data: Google, EnviroStor
There are quite a few Superfund sites concentrated in Santa Clara, Sunnyvale, and Mountain View, but they can be found in San Jose, East Palo Alto, Scotts Valley, Cupertino, Palo Alto, and more areas in Silicon Valley.
