No, the median SFH sales price in Santa Clara county is ~1.4 million. I just looked it up. https://scc.rereport.com/market_reports
Mountain View is one of the most expensive cities in the county, second to Palo Alto and maybe Los Altos. Most of the area is cheaper.
Low-end SFHs - we're talking a 3/2 built in the 1950s - go for about $1.8-$1.9M in Mountain View, $1.6-1.7M in Sunnyvale. A SFH like what you'd get in most of the rest of the U.S. - 4/2.5 or 5/3 on 1/4 acre lot, built somewhere between the 70s and 00s - will run about $2.4-2.8M.
