I live up in pismo - keep looking. They are out there, but yes prices here are high.
I see specials sell in 3k+ all day for bikes that need work.
A good looking standard is 5k
I picked up a titled project bike a year or so ago for $200, they are out there but you gotta be hunting and on the ball to get em. (They are now the exception, not the rule)
Keep an eye on Craigslist in Ventura and SB.
Or you can do what I’ve done with about half of my bikes, buy em out of state and ship em in. Even with shipping, usually much cheaper (this applies to complete running and usually original bikes).
That bike listed in fallbrook looks far from ready to ride, as in it needs to be torn down and painted. Controls look like old junk, engine looks a bit crusty, by the time it was a proper bike, you’d be maybe another 2-3k into it if you do all the work. For over 5k you should expect a complete, solid bike.
Maybe the bike is painted to look rusted and old??? Idk
