The latest Coldwell Banker annual ranking of what big houses cost across the United States puts Wellesley at #10 — California markets account for the top 9.

The definition of a big house here — 4 bedrooms, 2 bathrooms — might seem modest by Wellesley standards, but nevertheless, that’s what this ranking is based upon. The average cost for such a house in Wellesley is $1.1 million, according to the report, which surveyed some 51,000 similar-sized houses in about 2,000 markets nationwide.

Tops on the list is Los Altos, with an average price of nearly $2 million. Surprisingly, New York and Connecticut didn’t have any markets on the top 10 list, with Greenwich leading the way in Connecticut with an average price of $924K.

The brokerage firm also looked at the most affordable markets, and Cleveland topped that list at about $65K.
