I remember riding my bike up in the Skylonda area! I believe you will need to market very personally and creatively. The weekends at Alice's restaurants would be a good time to clearly sign open house events; also I would promote to the equine community in that area as people who like horses like to be in that area.
In the winter months, there is a lot of Christmas tree traffic, so you might say something like "visit the house and get $5 off of Xmas tree park," and get with the Xmas tree park to get a coupon because they like the business too.
Additionally you want to just FLOOD photos so maybe 35 to 45 photographs of the home showing every single angle so that people who are considering visiting will get that feeling before they have to make the drive.
Then I would make sure to publicize to every agent who has represented a buyer or seller in Skylonda for the last 24 months. Because if they have, they may have other buyers who they can "wake up" by sending them information about your home. I would extend this into Pescadero and down into La Honda and possibly Woodside.
I would also give the house a story. Something interesting, do the research (or your agent can do this). Figure out how to talk about it so it sounds extremely interesting. Historical facts that will set it apart. You may not have those, but if you can find anything out about it that makes it unique and different, this is an attractive thing.
Then also post on craigslist every week for at least six months. Because you never know when it will catch your buyer's eye.
And finally I like to get a "sold" rider and place it inside your bedroom so you look at it every morning. I know that is slightly unusual but seeing it "done" is a good way of opening up to opportunities and getting clear.
I wrote a blog about clearing clutter, that is a timeless bit of wisdom you shouldn't over look.
I love that area of Skylonda and rode my bike a lot in that area as a child. It is so beautiful!
