A rare opportunity to own a substantial piece of Mill Valley history, this 12+ acres of pristine verdant land is situated near downtown Mill Valley. Areas of the property are reminiscent of the early 1900's with meandering paths, original stone walls, a magical fountain with waterfall and flourishing landscaping replete with Redwood, Palm and Magnolia trees, some over 100 years old. This south facing property is enveloped by lush gardens with abundant fruit trees and has private water rights. Three separate buildings on site: a main residence with 4-BD and 4-BA, a guest house with downtown S.F. views and 1-BD, 1.5-BA, kitchenette, pool and spa, plus a charming studio cottage with a Murphy bed, kitchenette and bath. The property is comprised of 9 contiguous lots. The gated estate is fenced and backs to trails accessible from a private gate. Special water rights from the creek off of Mt. Tam irrigates the entire landscaped area of the large parcel and also creates water storage for fire protection. An enchanting setting with the potential to create an amazing compound or retreat.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
