Weston, which has unsurprisingly been ranked as the state’s most expensive housing market, has also ranked nationally in a new report.

The Boston suburb is the seventh most expensive housing market in the country, according to Coldwell Banker Real Estate LLC’s Home Listing Report (HLR). In Weston, the average four-bedroom, two-bathroom home has a listing price of $1.2 million.

The HLR provides the average home listing price of four-bedroom, two-bathroom properties listed on the real estate company’s website between September 2010 and March 2011 from more than 2,300 North American markets.

Compared to the national average of $293,251, the average four-bedroom, two-bathroom home in Massachusetts overall was $528,557.

The survey reviewed 88 real estate markets in Massachusetts and found Springfield led the list of most affordable markets in the state, with an average home listing price of approximately $133,404 for property listings meeting the subject home criteria.

"This report clearly illustrates the local nature of real estate. Massachusetts has a range of housing markets and overall has a higher average home price than other parts of the country because of our stronger economy and higher employment numbers," said Rick Loughlin, president of Coldwell Banker Residential Brokerage New England. "Weston, which is among the most expensive housing markets in the nation, continues to be a desirable community because of its close proximity to jobs, its picturesque neighborhoods and its top-performing schools."
