Seems relatively low, but does it back up to Palomar Airport Road? I can’t tell from the pics.
Personally, although the houses in RD are nice, especially those up the hill, I have always thought they were somewhat overpriced because they don’t really have any amenities (like the pool at Rancho Carillo), but have a fairly steep HOA and mello roos. Also they are of course in the San Marcos school district.
Anyway, maybe its just somebody who actually wants to sell their home?
