I can see that you are discouraged about the lack of activity on the sale of your home.
The market overall is still sluggish.
In times of difficulty and uncertainty, people tend to opt for the familiar, for the safe comfortable choice.
Skyline and Skylonda is not for every buyer.
Many find the drive up La Honda Road difficult. Commutes to work are longer from Skyline than from the flats.
Families with kids may prefer to be closer to schools, shops, Little League practice, and AYSO soccer.
The trend the past 10 or 15 years in real estate has been for people to desire "close-in" locations - where they can walk to stores, schools, restaurants etc.
So the buyer pool for Skyline is more limited than for other more "conventional" locations in the flats.
So your home must be very attractively priced and show very well to attract any interest.
Your agent should have a virtual tour and lots of photos of your home and property so that buyers can look without taking the time to drive up and see your home.
Perhaps you agent could hold a broker's tour and offer a $100 gift certificate to a few realtors who come take a look.
If you property offers outstanding value compared to the same house in the flats, then a buyer may trade the nicer house for the longer commute.
I started selling real estate in 1978 out of an office in La Honda. For years, I was up and down Skyline showing and selling property. And I can tell you, buyers for Skyline are a special bunch - they need to want something different and be willing to deal with the cons of living on Skyline in exchange for the benefits of living in such a beautiful area.
So be sure your home is priced aggressively, shows well, and is marketed properly. Be patient.
