Homes for sale
This home's estimate is 0.7% lower than the average sale price ($1.45M) of 6 comparable homes.
A beautiful house with amazing views from a large deck. Outdoor spaces are difficult to take advantage of other than the deck. Access is along a narrow, uphill shared driveway with the neighbor, then a steep left turn. Manoeuvering cars can be a bit...
of a challenge. The lower floor is for the one car garage and the separate unit. The main floor has an open floor. There are steps in the house between split levels.
The house has been beautifully remodeled.
