That first one you linked to must be priced based on building something new there. The Zillow listing even has pictures of plans for a new house.

Here's a 2270sqft 3BR3B for $1.9M that I think is actually in Santa Barbara (looks like the edge of Riviera), although it doesn't really have a yard: https://www.zillow.com/homedetails/533-Conejo-Rd-Santa-Barba...
