What do homes sell for in Sunnyvale?
The median single-family sale in Sunnyvale was $2,820,000 in September 2026, at $1,653 per square foot. Across all of 2025, the median was $2,650,000. Individual homes range widely around the median depending on size, condition, and street.
How long does it take to sell a house in Sunnyvale?
The average Sunnyvale single-family sale took 10 days in September 2026. Well-prepared, correctly priced homes typically clear faster than the average; overpriced homes sit past it and often sell for less after a reduction.
Do homes in Sunnyvale sell over asking?
Yes, on average. Sunnyvale sellers collected 107% of list price in September 2026, which means the typical home sold above asking. Pricing to invite competition, rather than pricing at the ceiling, is what produces those results.
What does it cost to sell a home in Sunnyvale?
The main costs are agent commissions (negotiable, and set in your listing agreement), county transfer tax plus a city transfer tax where one applies, title and escrow fees, and any repairs or preparation you choose to invest in. The seller net sheet calculator on this site turns those into a single walk-away number for your price point.
When is the best time to list a home in Sunnyvale?
Spring and early fall bring the most buyer activity on the Peninsula, but the best month depends on inventory: listing when few comparable homes are active often beats listing in the busiest season. The listing timing calculator on this site shows the historical pattern, and Lisa reads current inventory before recommending a date.
How do I find out what my home is actually worth?
Automated estimates miss condition, upgrades, lot, and street. Lisa prepares a confidential valuation for your specific property, drawing on closed sales, active competition, and off-market activity, within 24 hours. Request it at lisamlum.com/selling/home-valuation.
