Price, days on market and sales count: MLSListings, Inc. via rereport.com, July 2026, single-family re-sale homes. Days on market is published as an average, not a median, and measures list date to contract rather than to close. Housing-stock figures where shown are US Census ACS 2020–2024 five-year estimates. Figures change monthly — ask me for the current month before making a decision on them.
Housing stock
Median year built 1976. The Sunnyvale West and Ponderosa neighbourhoods hold consistent postwar tract housing; the Murphy Avenue downtown core and the areas near Lawrence Expressway have absorbed substantial higher-density redevelopment. Lot sizes and setback rules vary meaningfully between the older tracts and the newer infill.
Getting around
Highway 101, Highway 237, Central Expressway and Lawrence Expressway all serve the city, with Caltrain at Sunnyvale and Lawrence stations. Moffett Field and the bayfront business parks sit to the north.
What Prop 19 means for a longtime Sunnyvale owner
Sunnyvale generated 41 single-family sales in July — the deepest transaction volume in the set outside San Jose — so pricing evidence here is more reliable than in the thinner markets. For a longtime owner, that depth makes the net-proceeds and tax-base modelling more dependable too.
If you are 55 or older you can carry your existing property-tax base to a replacement home anywhere in California, up to three times. Read the Prop 19 guide, or run your net proceeds to see what a sale actually leaves you.
Selling here
Only county transfer tax applies. Because so much of the city is attached product, be careful that any comparable set your agent shows you is genuinely detached-to-detached.
Straight about the numbers: the figures above are transcribed from the sources named, for the month named. They describe a market, not your house. Condition, location within the city, lot and timing move an individual sale far more than a median does. Nothing here is legal or tax advice — your attorney and CPA have the final word.
What’s your Sunnyvale home worth?
A median tells you about the market. It doesn’t tell you about your house. Send me the address and I’ll put together a real analysis by hand — genuinely comparable sales near you, condition adjustments, and an honest range. If it’s not a good moment to sell, I’ll say so.
