Not every home that sells is ever listed publicly. A meaningful share of transactions in Silicon Valley happen off-market or inside a Coming Soon window, before the property reaches Zillow and the MLS. If you are only watching the public portals, you are seeing a partial market.
What off-market really means
Off-market covers a few different situations. A seller who wants privacy and does not want the whole neighborhood walking through. A home being quietly shopped to a short list of agents with qualified buyers. A property in a Coming Soon period where the listing exists but public showings have not opened yet. In each case, access depends on relationships, not search alerts.
For a seller, a quiet sale is sometimes the right call and sometimes leaves money on the table. For a buyer, it is a way to see inventory with less competition, before a bidding war forms.
How buyers get early access
Through an agent who is actually plugged into the broker networks where these homes circulate. That means the Coldwell Banker and Compass private-listing networks, plus direct agent-to-agent relationships built over years. It is not a list you can subscribe to. It is who picks up the phone when another agent has a home coming and wants to test demand quietly first.
If you want to be on the receiving end of those calls, off-market access is where that starts: your criteria, matched against what is moving quietly before it goes public.
