The Ten Most Expensive Homes Sold in Marin County in 2021

byThomas Henthorne|January 28, 2024|inMarin Real Estate

The Town of Ross Again Features Prominently in the
Top 10 Most Expensive Homes Sold in Marin in 2021
My Listing (above) at 5 Norwood Avenue in Ross Sold in One Day for $505,000 Over Asking

The most expensive Marin County home sold in 2021 closed for $28,100,000, almost double the price of the most expensive home sold in 2020.  Once again the highly-desirable town of Ross features prominently on the list, hosting 4 in the top 10.  Marin saw another year of steady price appreciation, with the median home price increasing to $1.5 million at the end of November, after peaking at $1.820 million in July.

The red hot real estate market is reflected in this year’s numbers. The median of the top 10 home sales in 2021 was $20 million, double the median of 2019.  Just like last year, Four of the top ten most expensive homes sold were transacted off market then entered into MLS by their respective agents after the sales closed.

The market looks poised for a strong start to 2022, though the course of the pandemic is unknown given the Omicron variant surge. Check out my monthly Marin Real Estate Market Reports here for more commentary on the market. Wishing you and yours a very happy 2022!

Let’s go beyond the numbers. Call or text me at 415-847-5584 to discuss how I can help you attain your real estate goals in 2022.
